Building permits, zoning and land rules in Kings County (Brooklyn), New York
11Index Score / 100 #62 of 62 in New York
Kings County, New York is Brooklyn, where most construction requires a New York City Department of Buildings building permit and plan review before work begins1. NYC zoning maps and district rules, not a separate county ordinance, control land use and zoning approval across Kings County2. Sewer and septic approvals are separate again: the NYC Department of Environmental Protection certifies sewer connections, and a private on-site septic system needs its own city permit34.
Building permits, plan review, zoning compliance review, electrical and plumbing filings, inspections and certificates of occupancy for Kings County (the borough of Brooklyn); there is no separate Kings County building department, since NYC's Department of Buildings performs this function borough-wide

Do you need a building permit in Kings County (Brooklyn), New York?
Most construction in Kings County requires a building permit from the New York City Department of Buildings, and an application must go to DOB for Building Code review before work begins10. Brooklyn projects are governed by the NYC Construction Codes, including the administrative, building, plumbing, mechanical, fuel-gas and energy provisions11. After permitted plumbing work is finished, the applicable inspection unit checks the installation and materials against the approved plans; inspection requirements depend on the work and inspection unit12. A new building must have a Certificate of Occupancy, while an existing building needs a current or amended certificate when its use, egress or occupancy type changes13.
Who issues building permits in Kings County, and how do you reach them?
The NYC Department of Buildings' Brooklyn Borough Office handles building matters for Kings County14. The office is at 345 Adams Street, 3rd Floor, Brooklyn, NY 11201, and customer service is (718) 802-367514. Certificate-of-occupancy questions go to (718) 802-3680; the office also publishes separate telephone lines for construction, electrical and plumbing development14. Depending on the filing type, an application may go through the borough office or DOB NOW: Build15. The published filing workflow includes a completeness check, fee assessment, data entry, plan review, resolution of objections and permit issuance15. Give the office the property address and exact project scope when asking which filing route applies.
Does Kings County have zoning?
Kings County is governed by the New York City Zoning Resolution and zoning maps rather than a separate county zoning system2. The mapped district may be residential, commercial, manufacturing or special-purpose, and its use, bulk, parking and special-permit rules determine what can be built2. Residential controls can cover lot size, yards, open space, lot coverage, height, setbacks and the permitted number of dwellings16171819. NYC permits one ancillary dwelling unit on a qualifying zoning lot with a single- or two-family residence, subject to an 800-square-foot cap and restrictions tied to flood risk, district, location, access and owner occupancy6. Check the parcel's mapped district and every special-purpose rule before designing the footprint or counting on an ancillary unit.
How do sewer connections and septic permits work in Kings County?
Brooklyn is served by the NYC public sewer system operated by the Department of Environmental Protection20. DEP approval is required when a project connects to a city sewer, and sewer certification is required for a new connection to a city sewer, private sewer, private drain, septic system or other approved outlet3. A New York State licensed Professional Engineer or Registered Architect must submit the certification for the owner or developer, and the later sewer connection permit authorizes the connection work21.
A private septic system is possible only in narrow cases: it is unlawful to construct, replace or substantially alter an individual private on-site sewage disposal system without a city permit, and no permit is issued where a public sanitary or combined sewer is available and connection is feasible as determined by DEP4. A registered design professional must prepare the construction documents, and the system must pass sand column and absorption testing before a permit is issued4. We could not confirm a general inspection program for private onsite systems, so ask the DOB Brooklyn Borough Office and DEP which approvals fit a parcel that cannot reach the public sewer14.
Can you live in an RV or tiny home on land in Kings County?
We could not confirm a general Brooklyn rule that allows or prohibits living in an RV, camping on a private lot, or occupying a tiny or manufactured home. A small dwelling is not automatically outside the ordinary approval system: NYC zoning controls land use and development, and most construction requires DOB plan review and a permit210. A homeowner who performs permitted work in the homeowner's own home may submit a Workers' Compensation Board waiver instead of the insurance otherwise required of a permittee, but the rule does not establish a broad owner-builder exemption7. Ask the Brooklyn Borough Office about the proposed structure, intended occupancy, duration, utilities and mapped zoning district before buying or placing a unit.
Building a home in Kings County (Brooklyn): the steps, in order
Identify the parcel's zoning district and any special-purpose district, then verify the allowed use and applicable bulk rules2.
Confirm the filing route and submit plans to DOB for Building Code review before construction begins22.
Resolve objections, pay the assessed fees and obtain the DOB permit before starting covered work15.
Obtain DEP sewer certification and the connection permit when the project needs a new sewer, private-drain, septic-system or other approved-outlet connection21.
Complete the inspections required for the permitted work12.
Obtain a Certificate of Occupancy or Temporary Certificate of Occupancy before occupying a new building13.
What should you check before buying land in Kings County?
Confirm the zoning map designation and special-purpose rules before relying on a proposed use, footprint or unit count2. Check the lawful occupancy record because a new building needs a Certificate of Occupancy and certain changes to an existing building require a current or amended certificate13. A property in a designated flood zone can face added zoning provisions and Building Code requirements23. A well supplying a building requires a city permit, and a potable-well applicant must show that municipal water is inaccessible8. A new curb cut needs DOB safety and zoning approval, a DOB work permit, and a sidewalk-and-curb permit from DOT9. If rental income matters, NYC requires short-term-rental hosts to register and bars booking platforms from processing unregistered rentals, subject to stated exemptions24.
Watch-outs
An ancillary dwelling unit is not automatically available on every Brooklyn lot; flood-risk maps, zoning district, location, access and owner-occupancy conditions can rule out a proposed unit6.
A homeowner insurance waiver does not create a general exemption from DOB permits or professional filing requirements7.
A Brooklyn curb cut requires approvals from both DOB and DOT before work begins9.
A private septic system on a Brooklyn lot needs its own city permit and is not issued where a public sewer connection is feasible, so confirm sewer access before planning an onsite system4.

Kings County rules
InspectionsLimited
New buildings and alteration work administered by the New York City Department of Buildings in Kings County (Brooklyn).
Inspection requirements depend on the scope and type of work.
For 1- and 2-family alterations, DOB requires inspections at various stages of completion and at final completion.
Plumbing, sprinkler, gas, and standpipe contractors may have self-certification options for specified inspections.
The cited page states that special and progress inspections may be required under Chapter 17 of the NYC Building Code.
“In accordance with AC 28-116.2 and BC 110.1, DOB requires inspections at various stages of completion during alteration work, as well as at final completion. Based on the scope of work, the following inspections from different DOB Inspection Units may be required:”
County-wide zoningPresent (with conditions)
Land use and development throughout Kings County, which is within the City of New York and is regulated through the NYC Zoning Resolution and its zoning districts.
The applicable requirements depend on the zoning district, applicable articles, zoning maps, and any Special Purpose District regulations.
The source describes the City of New York rather than using county terminology; the countywide scope is an aggregation for Kings County.
“establish the zoning districts for the City and the regulations governing land use and development.”

Present (with conditions) — Land use and building form in Kings County (Brooklyn), which is within New York City.
“This Resolution shall be known and may be cited as the Zoning Resolution of the City of New York.”
Local zoningVaries (with conditions)
Aggregate conclusion for Kings County: local zoning is governed by New York City’s Zoning Resolution, with regulations varying by City zoning district and applicable special-purpose district; the countywide claim aggregates the municipal/city zoning regime and does not assert that Kings County administers each ordinance.
The City of New York Zoning Resolution establishes zoning districts and regulations governing land use and development.
Articles I through VII contain use, bulk, parking, and other regulations for each zoning district.
Articles VIII through XIV establish regulations for Special Purpose Districts.
Specific use, bulk, parking, and development requirements depend on the applicable NYC zoning district and any applicable Special Purpose District.
“The Zoning Resolution consists of 14 Articles and 11 Appendices, plus 126 Zoning Maps, that establish the zoning districts for the City”

Varies (with conditions) — Aggregate conclusion for Kings County: zoning controls vary by NYC zoning district, zoning map, and special district, although the administering local government is the City of New York rather than Kings County government.
“Articles I through VII contain the use, bulk, parking and other applicable regulations for each zoning district.”
Minimum dwelling sizeDistrict specific (with conditions)
Certain pre-existing dwelling units and joint living-work quarters for artists governed by NYC Zoning Resolution §15-024, including specified historical occupancy categories; this is not a uniform Kings County minimum for every dwelling.
The section applies to units existing on September 1, 1980 with specified residential or joint living-work occupancy determinations, registered Interim Multiple Dwellings, or units found covered by the Loft Board under Article 7C of the New York State Multiple Dwelling Law.
Such units generally may not subsequently be divided into units or quarters of less than 1,200 square feet unless the Loft Board requires otherwise for legalization.
A unit may be no less than 415 square feet only if it has a window opening onto a street or 30-foot yard, the required window area is at least 8 percent of floor area with 50 percent openable, and the window wall is at least 12 feet wide.
Alternatively, a unit may be no less than 600 square feet only if the stated yard, court, street, window-area, distance, width, and ceiling-height conditions in §15-024(c)(2) are met.
minimum floor area: >= 415 square feet (Only under all conditions in §15-024(c)(1).) · minimum floor area: >= 600 square feet (Only under all conditions in §15-024(c)(2).) · subsequent division minimum: >= 1200 square feet (Applies to covered pre-existing units unless the Loft Board requires otherwise for legalization.)
“The minimum size of a #dwelling unit# or #joint living-work quarters for artists# may be no less than 415 square feet of #floor area#”
Septic permitRequired
Construction, replacement, or substantial alteration of an individual private on-site sewage disposal system in Kings County.
A permit issued by the department is required before constructing, replacing, or substantially altering the system.
The system must meet 1 RCNY §8001-01 or 10 NYCRR Part 75 and Appendix 75-A.
No permit will be issued where a public sanitary or combined sewer is available and connection is feasible as determined by NYC DEP.
No permit will be issued until the sand column and absorption testing requirements are met.
Construction documents for a new, replacement, or substantially altered system must be prepared by a registered design professional, except in-kind like-for-like plumbing repairs or replacements may be performed by licensed master plumbers.
Applications serving tax lots or zoning lots containing 15 or more dwelling units must be submitted to DOHMH unless DOHMH determines that individual systems are more practicable because of physical or engineering difficulties, estimated construction cost, or other pertinent considerations.
Applicable DEP, DEC, City Planning Commission, and Board of Standards and Appeals documents may be required before approval.
“It is unlawful to construct, replace or substantially alter an individual private on-site sewage disposal system without a permit issued by the department.”

Permit feesVariable (with conditions)
DOB NOW: Build permit and filing fees for construction, alteration, demolition, and related work in Kings County (Brooklyn).
DOB NOW calculates fees under the NYC Construction Codes as amended by Local Law 56 of 2016.
The fee amount depends on the relevant scope of work, building type, filing type, and, for specified filings, reported construction cost.
Beginning February 2, 2026, updated calculations apply to subsequent filings on an Alt-CO with existing building elements to remain, new full-demolition filings, and AHV permits.
For subsequent Alt-CO filings, the 2026 notice lists work types including plumbing, sprinkler, standpipe, general construction, mechanical systems, structural, support of excavation, and protection and mechanical.
For full demolition initial filings submitted on or after February 2, 2026, the record management fee is $45 for 1-, 2-, or 3-family buildings and $165 for other buildings.
The DOB NOW payment FAQ states that a 2% fee is added for credit card, debit card, PayPal, and Venmo payments, while eCheck has no fee; returned checks incur a $20 fee.
full demolition record management fee for 1-, 2-, or 3-family building: 45 USD (Initial filings submitted on or after February 2, 2026.) · full demolition record management fee for other building types: 165 USD (Initial filings submitted on or after February 2, 2026.) · electronic payment convenience fee for credit card, debit card, PayPal, or Venmo: 2 percent (eCheck payments have no fee.) · returned check fee: 20 USD (Added to the original fee for each returned check.)
“Fees will be calculated based on the construction cost reported on the filing, rather than the prior flat fee of $130.”
New York rules that apply here
Building permitRequired
Work that must conform to the New York State Uniform Code or Energy Code throughout New York State except New York City, where the city has its own construction code; local authorities having jurisdiction administer and enforce the state requirements within their boundaries.
A local authority having jurisdiction may expressly exempt one or more listed categories of work from the building-permit requirement.
Permitted exemption categories include one-story detached tool or storage sheds, playhouses, or similar structures associated with one- or two-family dwellings or townhouses not exceeding 144 square feet gross floor area; temporary sets and scenery; certain window awnings; partitions or movable cases less than 5 feet 9 inches high; painting, wallpapering, tiling, carpeting, or similar finish work; listed portable equipment or appliances; certain equipment replacements; and repairs that do not affect fire and life safety.
A permit exemption does not authorize work violating the Uniform Code or Energy Code.
Beginning December 31, 2025, regulated parties submitting building permit applications must comply with the 2025 NYS Uniform Code, subject to the stated transition option before that date.
maximum gross floor area for listed detached accessory structures: <= 144 square feet (Only for one-story detached structures associated with one- or two-family dwellings or townhouses and used for tool/storage sheds, playhouses, or similar uses.) · height threshold for listed partitions or movable cases: < 5 feet 9 inches
“Each authority having jurisdiction shall include in its code enforcement program provisions requiring building permits to be required for work that must conform to either or both of the Codes.”
Owner-builder exemptionConditional
Owner-performed home-improvement work at an owner’s primary residence in New York, as to a New York State home-improvement-contractor license.
New York State does not license home-improvement contractors.
A county or local municipality may license home-improvement contractors or particular home-improvement trades.
The Department of State identifies New York City; Suffolk, Nassau, Westchester, Putnam, and Rockland Counties; and the City of Buffalo as examples of local jurisdictions requiring a home-improvement-contractor license.
This finding concerns home-improvement-contractor licensing only; it does not establish an exemption from locally administered building permits, inspections, or licenses for particular trades.
“Check your local government licensing requirements: New York State does not license home improvement contractors. However, some counties and local municipalities do, including New York City, Suffolk, Nassau, Westchester, Putnam, and Rockland counties, and the City of Buffalo.”
Building code adoptedAdopted
The New York State Uniform Fire Prevention and Building Code for construction statewide outside New York City, including residential construction in towns and other local governments.
The Uniform Code took effect January 1, 1984.
New York City was permitted to retain its own code.
Cities, towns, and villages outside New York City do not need to adopt the Uniform Code affirmatively; it is automatically in effect.
A local government cannot exclude itself from all or any part of the Uniform Code.
Building permits must be required for work that must conform to the Uniform Code, subject to permitted exceptions.
effective date: 1984-01-01
“The Uniform Code is applicable in every part of the State (except the City of New York, which was permitted to retain its own code).”
Certificate of occupancyRequired
Work subject to a building permit and the Uniform Code or Energy Code, and structures or portions converted from one use or occupancy classification or subclassification to another, throughout New York State except New York City.
Permission to use or occupy covered buildings or portions is granted only by issuance of a certificate of occupancy or certificate of compliance, except as provided for temporary certificates of occupancy.
Before issuance, the authority must inspect and determine compliance with applicable Codes and, where applicable, review structural-observation statements, special-inspection reports, flood-hazard certifications, Energy Code test results, and manufactured-building or manufactured-home seals, insignias, and data plates.
A temporary certificate may be issued before completion for a specified period and specified portions, subject to safe occupancy, operational fire and life-safety components, required means of egress, and completion of remaining work.
temporary certificate period: specified period (The permit holder must undertake to bring the structure into full compliance with the Codes.)
“The code enforcement program shall provide that, except as provided in section 1203.3 (d)(4), permission to use or occupy a building or structure, or portion thereof, for which a building permit was previously issued, or which has been converted from one use or occupancy classification or subclassification to another, shall be granted only by issuance of a certificate of occupancy or a certificate of compliance.”
Zoning districtsPartial
Publication and adoption of zoning districts by New York municipalities statewide; zoning is locally adopted and administered rather than administered by New York State as a single statewide zoning map.
Zoning districts are shown on each municipality’s zoning map.
A New York municipality has the choice whether to adopt zoning and, if adopted, how the zoning regulations will work in the community.
The source states that all New York cities have adopted zoning, while towns and villages may adopt zoning under the applicable enabling laws and local procedures.
District-specific zoning regulations and maps must therefore be obtained from the relevant city, town, or village.
The cited publication discusses local adoption procedures and does not publish a single statewide set of zoning districts.
“Since New York is a home rule state, a municipality has the choice of whether or not to adopt zoning and if it does, how the zoning regulations will work in the community.”

Partial — New York cities, towns, and villages that enact local zoning laws and zoning districts
“New York’s zoning enabling statutes (the state statutes which give cities, towns and villages the power to enact local zoning laws) require that zoning laws be adopted in accordance with a comprehensive plan.”
Who permits septicMixed (with conditions)
Residential and other septic or cesspool systems statewide in New York.
New York State DEC administers SPDES permitting for regulated wastewater discharges.
For systems with less than 1,000 gallons per day of sewage-wastewater discharge to groundwater and no industrial or other non-sewage wastes, approval may still be required from the appropriate city health department, county health department, or district office of the New York State Department of Health before construction.
The actual local or district health authority depends on the property location.
groundwater discharge design flow threshold: < 1000 gallons per day (No industrial or other non-sewage wastes)
“city health department, county health department”
One more reviewed finding on this topic
Mixed (with conditions) — Residential individual onsite wastewater treatment systems throughout New York State, including alternative systems under Appendix 75-A.
“State or county health department official”
Septic inspectionLimited
Post-construction certification for residential alternative onsite wastewater treatment systems under Appendix 75-A.
A design professional must supervise construction.
The design professional must certify after construction that supervision occurred and that construction conforms to approved plans.
The cited passage establishes certification, not a general periodic inspection schedule for routine operation.
“a design professional shall provide [...] a certification”
Off-grid sanitationAllowed (with conditions)
Use of an individual onsite wastewater treatment system where a municipal or communal wastewater system is unavailable.
The system must comply with statewide Appendix 75-A minimum standards.
Alternative systems require prior review and approval by the State or county health department official having jurisdiction.
Design must be prepared by or under the supervision of a design professional.
“when a municipal or communal system is not available”
Mandatory utility hookupConditional
Residential realty subdivisions, including subdivisions of fewer than 50 lots.
Community water and/or sewers may be required when public services are available, groundwater quality or quantity is poor, or site conditions are unacceptable for onsite wastewater treatment systems.
The source addresses subdivision approval and does not establish a universal statewide connection mandate for every individual residential parcel.
“Yes, if there is good reason such as: public services are available”
Agricultural exemptionConditional
Farm operations located within a New York agricultural district, including associated land, on-farm buildings, equipment, manure processing and handling facilities, and qualifying agricultural practices.
The protection applies only to farm operations in an agricultural district.
Local governments must exercise their planning and land-use authority consistently with Article 25-AA of the Agriculture and Markets Law.
Local governments may not unreasonably restrict or regulate the covered farm operation unless public health or safety is threatened.
Only farm operations are protected; the Department evaluates whether the regulated activity encompasses a farm operation.
The reasonableness analysis considers whether the restriction is unreasonable on its face and as applied to the particular situation, and depends on the totality of the circumstances.
A farmer, municipality, or other eligible requester may seek a Department opinion concerning the effect of a proposed or existing local law or ordinance.
If the Department determines that a local law or ordinance is unreasonably restrictive, it may seek remediation and the Commissioner may issue an order to comply or bring an enforcement action.
“Local governments, when exercising their powers to enact and administer comprehensive plans and local laws, ordinances, rules or regulations, shall exercise these powers in such manner as may realize the policy and goals set forth in this article, and shall not unreasonably restrict or regulate farm operations within agricultural districts in contravention of the purposes of this article unless it can be shown that the public health or safety is threatened.”

Available (with conditions) — Agricultural uses and agricultural-use structures within the Adirondack Park Agency jurisdiction, including relevant Freshwater Wetlands Act and Wild, Scenic and Recreational Rivers System Act permitting contexts.
““Agricultural uses” and “agricultural use structures” are generally exempted from permitting requirements under New York State’s Adirondack Park Agency Act”
Subdividing landLimited
Subdivision review by a town planning board for land outside the limits of an incorporated village in New York.
The town board may authorize and empower the planning board only by resolution.
Town Law § 276 applies to the part of a town outside the limits of an incorporated village.
Subdivision means division of a parcel into lots, blocks, or sites as specified in a local ordinance, law, rule, or regulation, with or without streets or highways, for sale, transfer of ownership, or development.
Local regulations may define subdivisions as major or minor and must set the review procedures and criteria for each.
Preliminary and final plats must comply with applicable State Environmental Quality Review Act requirements.
A final plat receiving conditional approval does not qualify for recording and does not authorize building permits until the required conditions are completed, the plat is signed by an authorized planning-board officer, and the plat is recorded.
An approved final plat must generally be filed with the county clerk or register within sixty-two days after final approval or the approval expires.
minimum unimproved-lot threshold for previously filed plat to be treated as undeveloped: >= 20 percent (unless existing conditions, such as poor drainage, have prevented development) · final plat filing deadline after final approval: 62 days (otherwise approval expires) · partial approved plat filing threshold: >= 10 percent of total lots (remaining sections are subject to the statutory expiration rule)
“the town board may, by resolution, authorize and empower the planning board to approve preliminary and final plats of subdivisions showing lots, blocks or sites, with or without streets or highways, within that part of the town outside the limits of any incorporated village.”

“the town board may, by resolution, authorize and empower the planning board to approve preliminary and final plats of subdivisions”
Driveway accessRequired
New or modified commercial access to a New York State highway, including changes of use or expansions of existing development on a State highway.
A highway work permit from NYSDOT is required.
The commercial driveway/access permit review generally consists of initial proposal review, design review, and final submission review.
Final submission may require insurance documentation, performance security, permit fees, and additional documentation.
A simple commercial driveway project may qualify for a single-stage expedited review if it meets the applicable criteria.
The page states that the PERM 33-COM application and checklist is used for commercial highway work permit submissions, including minor or major commercial driveways, minor home business driveways, or subdivision streets.
“If your commercial property development plans involve new or modified access to a state highway, or involve any change of use or expansion of an existing development on a state highway, you will need a highway work permit from the New York State Department of Transportation (NYSDOT).”

“If your residence is on a State highway, you will need a permit from the NYS Department of Transportation to build or modify a driveway.”
Building in a floodplainRequired
Development in FEMA-mapped Special Flood Hazard Areas in New York State, with local administration by the municipality having jurisdiction.
Local communities participating in the National Flood Insurance Program regulate development in Special Flood Hazard Areas.
Private development is subject to local floodplain development permits.
Development funded and undertaken by the State or Federal government is an exception to the local-permit rule and is regulated by the responsible agency, subject to technical assistance by NYSDEC and FEMA.
Each participating community has a designated floodplain administrator, usually the building inspector or code enforcement official.
The local laws apply to development undertaken by any county, city, town, village, school district, or public improvement district within the community.
The source states that any new structure or structure substantially improved or substantially damaged is subject to floodplain development regulations, with substantial improvement or damage exceeding 50% of the structure’s market value.
substantial improvement or damage threshold: > 50 percent of structure market value
“Private development is subject to local floodplain development permits.”
Permit processPublished (with conditions)
Building-permit applications for work subject to the New York State Uniform Code or Energy Code, administered through the authority having jurisdiction’s code-enforcement program.
A building permit is required for work that must conform to the Uniform Code or Energy Code.
The code-enforcement program may exclude listed categories, including qualifying detached structures not exceeding 144 square feet, temporary sets and scenery, certain awnings, partitions or movable cases under 5 feet 9 inches, finish work, listed portable equipment, qualifying equipment replacements, and repairs that do not affect fire and life safety.
Excluded work must still conform to applicable Uniform Code and Energy Code provisions.
An authority having jurisdiction may instead require permits for all work subject to the Uniform Code and Energy Code.
Applications must include, at minimum, the work location, nature, extent and scope; tax map number and street address; occupancy classification; applicable special-inspection statement; and acceptable construction documents.
Construction documents may need site plans, code-compliance information, structural and building-system information, Energy Code compliance, flood-hazard information, and licensed architect or professional-engineer documentation where applicable.
detached accessory structure exemption threshold: <= 144 square feet (one-story detached structures associated with one- or two-family dwellings or multiple single-family dwellings used for tool/storage sheds, playhouses, or similar uses) · movable partition or case exemption height: < 5 feet 9 inches
“An authority having jurisdiction’s code enforcement program must require any party who proposes to perform any work which must conform with the Uniform Code”

“The application and review process generally consists of the following three stages of review:”
Campground & park staysLimited
Temporary camping at New York State Department of Environmental Conservation campgrounds statewide.
All campers must register and obtain a camping permit.
Check-in is from 2:00 p.m. to 9:00 p.m.; campers must register and occupy the campsite by 9:00 p.m. on the first reservation night or the campsite may be re-rented and fees may be forfeited.
Campers must vacate by 11:00 a.m. on the final day.
Camping permits are limited to 14 nights but may be renewed depending on site availability.

county building authorityLimited
County administration and enforcement of the Uniform Code and Energy Code within a local government, including unincorporated town areas, when the local government has opted out or when the Secretary of State designates the county.
Every local government ordinarily administers and enforces the Uniform Code and Energy Code.
A local government may opt out by local law enacted before July 1; the opt-out becomes effective January 1 of the following year.
After a local-government opt-out, the county administers and enforces the codes within that local government.
The county may itself enact a local law opting out; if both local government and county opt out, the Secretary of State administers and enforces the codes.
Counties may charge fees to defray administration and enforcement costs.
A responsible county must establish a code-enforcement program by local law, ordinance, or other appropriate regulation.
local-government opt-out deadline: < July 1 · successor enforcement date: January 1 (the January 1 next succeeding the effective date of the local law)
“The secretary may designate the county in which such local government is located to administer and enforce the uniform code in such local government.”
