Building permits, zoning and septic rules in Cheshire County, New Hampshire
73Index Score / 100 #5 of 10 in New Hampshire
Cheshire County, New Hampshire has no county zoning or building department: each of the county's towns handles building permits and zoning on its own1. New Hampshire's state building code still requires a permit before most new construction, regardless of whether a given town runs its own building office2. We use Keene — the county seat and Cheshire County's largest city — as a worked example of how a town-level building and planning office works; contact your own town's office for its specific rules and fees3. Septic approvals come from the state, not the town or county4.

Do you need a building permit in Cheshire County, New Hampshire?
Cheshire County has no county building department, but a building permit is still required almost everywhere in New Hampshire before new construction begins: state law puts a duty on the person responsible for construction to obtain a permit before starting covered work211. Most Cheshire County towns enforce that requirement locally, through their own building or code office, following whatever process that town has adopted11. Once an application is complete, the building official must approve or deny an ordinary application within 30 days; the deadline is 60 days for a nonresidential application or a residential project encompassing more than 10 dwelling units12. In a town that has not adopted its own enforcement mechanism, the state fire marshal runs a state building permit system instead, though that state-run system does not cover an ordinary one- or two-family home; ask your town clerk who currently issues residential permits if your town has no building office11. Every Cheshire County building must meet the state building code, which is built on the 2024 International Residential Code and International Building Code13. A town cannot issue a permit for work that would violate its zoning ordinance, the building code or planning-board regulations14. A residence occupied by the owner and the owner's immediate family is exempt from the town's local enforcement mechanism unless the premises pose a clear and imminent danger to people other than the occupants, but that provision is not stated as an exemption from the state building code itself, so ask your town's building office before assuming no permit is needed5. Keene, the county seat and Cheshire County's largest city, is a worked example: its Building Safety staff reviews, approves, issues and inspects all construction in the city, including structural, electrical, plumbing, mechanical, accessibility, energy-efficiency and floodplain-development work3.
Who handles building permits and zoning in Cheshire County, since the county doesn't?
Cheshire County itself runs no zoning, planning or building department; its own list of county departments covers things like the sheriff, registry of deeds, corrections and human services, not land use1. Zoning and building permits are a municipal function everywhere in New Hampshire, so the office you need depends entirely on which of Cheshire County's towns your land sits in1. In Keene, that office is the Community Development Department, which runs both Building Safety and Planning & Zoning out of one office, reachable by phone or email315. If your land is in one of the county's smaller towns, start with that town's own town hall or select board office instead of Keene's, since each town sets and enforces its own rules1.
Does Cheshire County have zoning?
No: Cheshire County has no zoning ordinance and no planning department, and it exercises no zoning authority over any land in the county1. Zoning in New Hampshire is set town by town, and a town's planning board only regulates subdivision of land if that town has specifically authorized the planning board to do so by ordinance or resolution16. Even a farm or ranch building is not automatically exempt from a town's dimensional standards, setbacks, driveway rules or similar requirements; New Hampshire law lets a local board grant a waiver for an agricultural use only after notice and a hearing, and only to the extent needed to reasonably permit that use17. Because rules genuinely differ from one Cheshire County town to the next, confirm your specific parcel's zoning district and any subdivision requirements with that town's own office, such as Keene's Planning & Zoning staff for property inside the city15.
How do septic permits work in Cheshire County?
Septic permits in Cheshire County go through the state, not the county or even the town: the New Hampshire Department of Environmental Services requires prior approval of plans before anyone builds a structure that will discharge sewage or constructs a septic system418. You need both an approval for construction and an approval for operation before you can use a new system, and locally approved plans must also be submitted where a town planning board or other local body requires them1920. Soil is a real constraint here: only 10.9% of Cheshire County's soil rates free of severe limits for a conventional septic drain field in the USDA's survey, so budget for a site evaluation and the possibility of an engineered system on much of the county's land8. Some towns require local approval of water-supply and sewage-disposal plans before you apply to NHDES, so ask the town first21. On developed waterfront property with any part of the septic system within 250 feet of the reference line, the buyer must obtain a septic evaluation from a New Hampshire licensed evaluator before the transfer, unless the buyer replaces or repairs the system within 180 days and gives the required notices22. If a public sewer is within 100 feet of your building, state law requires connecting to it instead of using a septic system23.
Can you live in an RV or tiny home on your land in Cheshire County?
New Hampshire's recreational-campground law governs RVs at licensed, regulated campgrounds and camping parks, where a site is for temporary recreational occupancy only, not year-round residency, unless that site meets the same construction standards as a single-family house6. Outside a licensed campground, the same law lets a landowner host an RV on their own parcel for occasional use of no more than 7 days in a calendar year, but only after filing a statement of compliance with the town's governing body within 7 days before that use6. Neither provision creates a general right to live in an RV on ordinary land year-round; that question depends on your specific town's zoning ordinance, so confirm it with your town's planning or zoning office before you buy1. A composting or incinerator toilet needs no state sign-off if the structure has no internal plumbing and no supplied water service, which is worth knowing if you are building a simple cabin without a well or septic system24.
Do you need a driveway permit in Cheshire County, New Hampshire?
A driveway, entrance or approach onto a New Hampshire state highway needs a written permit from the state Commissioner of Transportation before construction or alteration begins7. If 400 feet of all-season safe sight distance cannot be obtained in both directions, no more than one access to the parcel may be permitted, and a qualifying residential application gets a decision within 60 days7. A driveway onto a town road is a different question: the town's own road agent or select board sets that process, and we could not confirm it for any Cheshire County town, so ask the town office before you clear a drive.
How do you build a home in Cheshire County, New Hampshire, step by step?
Contact your specific town's building or code office (or the Community Development Department if you're in Keene) to confirm local zoning, setbacks and the permit process before you design15.
If your lot needs a septic system, get your design approved by the New Hampshire Department of Environmental Services and obtain a construction approval before building starts1918.
Apply for your building permit through your town's building office if it has adopted its own enforcement mechanism; otherwise check with your town clerk about the state fire marshal's building permit system11. A building official must approve or deny a completed ordinary application within 30 days, while a nonresidential application or residential project encompassing more than 10 dwelling units has a 60-day decision deadline12.
If the driveway meets a state highway, get the state driveway permit before construction7.
Build to the state building code and request the required inspections as work proceeds, including before any work is concealed25.
Get your septic system's approval for operation from NHDES before you use it, in addition to the earlier construction approval19.
Close out with a certificate of occupancy where your town requires one, after final inspections confirm the work meets state and local codes26.
What should you check before you buy land in Cheshire County?
Confirm which town your parcel sits in and call that town's office directly, since Cheshire County itself sets none of the zoning, building or subdivision rules that will govern your land1. Test the soil before you count on a simple septic system: with only 10.9% of the county's soil rated free of severe limits for a conventional drain field, many lots will need an engineered system and a New Hampshire Department of Environmental Services site evaluation8. If you plan to drill a well, know that the contractor must file a completion record with the state within 90 days, so ask for a copy for your own records27. Property taxes run well above the national norm here: the effective rate is about 2.3% of assessed value, producing a typical annual bill near $5,968, so factor that into any purchase928. Homeowners insurance is comparatively affordable, with a typical policy near $1,375 a year29.
Watch-outs
Cheshire County has no zoning, building or planning department of its own; every rule that matters for your land is set by the specific town it sits in, so confirm directly with that town before you buy1.
New Hampshire's occasional-RV-use exception is capped at 7 days a year and requires filing a statement of compliance with the town in advance; it is not a path to living on raw land in an RV6.
An owner-occupied residence is exempt from the town's local enforcement mechanism, but we could not confirm that this removes the need for a permit or inspection; ask your specific town's building office before acting as your own contractor5.

Zoning districtsPublished
New Hampshire's statutory zoning-district framework, under which a local legislative body may divide a municipality into zoning districts and regulate buildings, structures, and land within those districts.
The statute supplies enabling authority and does not publish the actual district maps or district schedules for each municipality.
District boundaries, number, shape, area, and regulations are determined locally by the municipality's local legislative body.
Regulations must be uniform for each class or kind of building throughout each district, but regulations may differ between districts.
Local zoning remains a municipal-government responsibility.
“The local legislative body may divide the municipality into districts of a number, shape and area as may be deemed best suited”
Minimum lot sizeDistrict specific
New Hampshire municipalities and qualifying counties may adopt local zoning regulations governing lot sizes; the statute does not set a single statewide minimum lot size.
The actual minimum depends on the locally adopted zoning ordinance and district.
The cited statute authorizes local regulation and is not itself a numeric minimum-lot-size rule.
“For the purpose of promoting the health, safety, or the general welfare of the community, the local legislative body of any city, town, or county in which there are located unincorporated towns or unorganized places is authorized to adopt or amend a zoning ordinance under the ordinance enactment procedures of RSA 675:2-5.

SetbacksDistrict specific
New Hampshire municipalities and qualifying counties may adopt local zoning regulations governing yards and other open spaces that may include setback controls; the exact setback depends on the local ordinance and district.
The actual setback distance depends on the locally adopted zoning ordinance and district.
The cited statute authorizes local dimensional regulation and is not itself a numeric setback rule.
“The zoning ordinance shall be designed to regulate and restrict: [...] Lot sizes, the percentage of a lot that may be occupied, and the size of yards, courts and other open spaces;”
Lot coverageDistrict specific
New Hampshire municipalities and qualifying counties may adopt local zoning regulations limiting the percentage of a lot that may be occupied; the exact percentage depends on the local ordinance and district.
The actual lot-coverage limit depends on the locally adopted zoning ordinance and district.
The cited statute is an enabling provision and does not establish a statewide percentage.
“The zoning ordinance shall be designed to regulate and restrict: [...] Lot sizes, the percentage of a lot that may be occupied, and the size of yards, courts and other open spaces;”
Building heightDistrict specific
New Hampshire municipalities and qualifying counties may adopt local zoning regulations governing building height and number of stories; the exact height depends on the local ordinance and district.
The actual building-height limit depends on the locally adopted zoning ordinance and district.
The cited statute authorizes local regulation and does not establish a statewide height limit.
“The zoning ordinance shall be designed to regulate and restrict: (a) The height, number of stories and size of buildings and other structures;”

Septic inspectionLimited
Proposed sewage or waste disposal systems and certain waterfront property transfers in Cheshire County
Inspection responsibility may be delegated to a full-time local health officer, building inspector, or other qualified local official.
For developed waterfront property with any portion of the septic system within 250 feet of the reference line, the buyer must obtain an evaluation before transfer.
A transfer evaluation is not required if the buyer replaces or repairs the system within 180 days and gives the required notices and report.
If failure is determined, the buyer must replace the system within 180 days and file the state approval for operation.
waterfront distance: <= 250 feet (Any portion of the septic system within 250 feet of the reference line under RSA 483-B:4, XVII.) · replacement or repair deadline: 180 days (Buyer may avoid the evaluation requirement by notifying the department and local health officer before transfer and completing replacement or repair within 180 days.)
“the buyer of the property shall, at the buyer's expense, engage a New Hampshire licensed septic system evaluator to conduct a septic system evaluation.”

Required — Construction, operation, and maintenance of subsurface sewage disposal systems statewide in New Hampshire.
“Septic tanks shall be inspected for accumulation of sludge and surface scum at a frequency sufficient to allow the tank to be pumped by a licensed septage hauler when the combined thickness of the sludge and surface scum equal 1/3 or more of the tank depth.”
Off-grid sanitationLimited
Composting or incinerator toilets in New Hampshire structures.
Department approval is not required where the structure has neither internal plumbing nor supplied water service.
If the structure has internal plumbing and water service from a drilled well, internal or external storage tank, or municipal water system, an ISDS with DES operational approval is required even if the toilet is not connected to it.
Toilet waste disposal must comply with applicable state rules and local law.
“Composting toilets and incinerator toilets in structures that do not have internal plumbing and that do not have a supplied water service to the building shall not require approval by the department.”
Well permitLimited
Private and other water wells constructed in New Hampshire, including special requirements for open-loop geothermal wells.
Within 90 days after completion, the water well contractor must provide the New Hampshire Water Well Board a well completion record containing the specified location, construction, yield, use, and contractor information.
Open-loop geothermal wells require a groundwater discharge permit under Env-Wq 402.33 through Env-Wq 402.36.
The reviewed sources establish reporting and special-purpose permit requirements; they do not establish a universal construction permit requirement for every ordinary private well.
well completion record deadline: 90 days after completion
“An owner of an open loop geothermal well shall obtain a groundwater discharge permit in accordance with Env-Wq 402.33 through Env-Wq 402.36.”
Mandatory utility hookupConditional
Buildings occupied or used for dwelling, office, store, theater, public hall, sleeping apartment, or tourist cabin in New Hampshire.
Connection to a public sewer is required if one is within 100 feet.

Agricultural exemptionConditional
New, re-established, or expanded agricultural operations and activities subject to local building and site requirements in New Hampshire.
Agricultural operations are not categorically exempt from dimensional standards, setbacks, driveway and traffic regulations, parking, noise, odor, vibration, or sign regulations.
A waiver may be required where literal application would effectively prohibit an agricultural use allowed by the statute or would otherwise be unreasonable in the agricultural context.
The waiver requires due notice and hearing by the board of adjustment, building code board of appeals, or other applicable local board.
The waiver must be limited to the extent necessary to reasonably permit the agricultural use or activity.
No waiver is required if it would have a demonstrated adverse effect on public health or safety or on the value of adjacent property.
The waiver continues only while the property is utilized for the permitted agricultural use or activity.
RSA 147 health-and-safety findings and the duties of the Department of Environmental Services under RSA 485 or RSA 485-A, and the Commissioner of Agriculture, Markets, and Food under Title XL, are preserved.
The statute does not affect regulation of sludge or septage.
approval mechanism: waiver after due notice and hearing (only to the extent necessary to reasonably permit the agricultural use or activity) · adverse-effect limitation: demonstrated adverse effect on public health or safety, or on the value of adjacent property (waiver unavailable where this limitation applies)
