Building permits, zoning and land rules in Delta County, Texas
71Index Score / 100 #36 of 254 in Texas
Unincorporated Delta County, Texas has no residential building-permit requirement and no zoning ordinance, because Texas gives counties building and zoning authority only in narrow situations that don't apply here123. The county's Development Services office does administer subdivision rules, driveway and culvert permits, and septic (on-site sewage facility) permits as the local TCEQ-authorized agent4. Inside the City of Cooper, the city's own zoning ordinance applies, and septic permits still come from the county54.

Do you need a building permit in Delta County, Texas?
Unincorporated Delta County has no residential building-permit requirement1. Texas law lets a county adopt a fire code and permits only if the county has more than 250,000 people or borders one that does, and then only for commercial, public and large multifamily buildings; Delta County's population of 5,520 is far below that mark98. Delta County does run a Development Services office, but its published permits cover subdivision rules, driveway and culvert installation, and septic permits, not a residential building permit110. Inside the City of Cooper, ask the city whether it requires building permits for your lot; the county does not issue them either way5.
Who do you call in Delta County for permits?
Delta County's Development Services office is the right place to start for anything related to land development: subdivision rules, driveway and culvert installation onto a county road, and septic permits101112. The County Judge's Office oversees county administration and the Commissioners Court, and is the office to ask about anything not posted online, including floodplain questions13. Neither office reviews building plans or issues a residential construction permit, because unincorporated Delta County doesn't run that program1.
Does Delta County have zoning?
Unincorporated Delta County has no zoning ordinance or zoning districts; the county regulates land outside city limits only through its subdivision rules and regulations2. Texas law gives counties zoning power only in narrowly defined special areas, and Delta County has not adopted county zoning143. As a result, no county rule sets minimum lot size, setbacks, lot coverage, building height or accessory-dwelling limits on unincorporated land, and the county does not restrict living in an RV, tiny home or manufactured home3. Inside the City of Cooper the answer is different: the city has its own zoning ordinance and a Planning & Zoning Commission, so city rules apply to any lot within Cooper5. If you are subdividing a tract outside a city, Delta County's subdivision rules still apply and are worth checking with Development Services before you plat10.
How do septic and well permits work in Delta County?
Delta County's Development Services administers on-site sewage facility (OSSF/septic) permits directly, acting as the local TCEQ-authorized agent rather than routing applications to a TCEQ regional office4. Statewide, every OSSF requires a permit before construction, installation, alteration, extension or repair15. A limited exemption applies only on tracts of at least 10 acres, and only if every condition is met: a licensed site evaluator signs off, it's a single-family home, all parts of the system sit at least 100 feet from the property line, and the tract has no other dwelling15. Private water wells may also need a permit if Delta County falls inside a groundwater conservation district, though that hasn't been confirmed for this county specifically; ask Development Services or the County Judge's Office before you drill161013.
Can you live in an RV or tiny home on your land in Delta County?
Delta County has no zoning ordinance, so there's no county rule restricting RV living, tiny homes or manufactured homes on your own land3. That's a real answer, not just an absence of research: Texas law gives Delta County no zoning power to regulate these uses in the first place3. Statewide rules about licensed RV parks and campgrounds don't apply to living in your own RV on your own land, so don't read those as a limit here. Whatever dwelling you choose, its septic system still needs a Delta County OSSF permit, since that requirement doesn't depend on the structure being a conventional house4. If you're subdividing land first, Delta County's subdivision rules still apply even though its zoning rules don't10.
Building a home in Delta County: the steps, in order
Confirm your parcel is in unincorporated Delta County and check whether it's already part of a platted subdivision, since the county's subdivision rules apply either way10.
Call Delta County Development Services to confirm the current culvert and driveway permit process before you build a new entrance onto a county road11.
Apply for a Delta County on-site sewage facility (OSSF) permit through Development Services before you design your septic system124.
If your tract is at least 10 acres, have a licensed site evaluator confirm in writing whether you qualify for the state's septic-permit exemption, since every condition has to be met15.
If you're adding or changing access onto a state highway rather than a county road, submit TxDOT Form 1058 and wait for a fully executed permit before starting work17.
Ask the County Judge's Office to confirm current floodplain status for your parcel before you finalize your building site13.
What to check before you buy land in Delta County, Texas
Delta County is one of the wetter, greener rural counties in this guide, averaging 46.1 inches of rain a year, with severe drought in only 21.1% of recent years and 21.5% of the land wooded181920. Soils here support a conventional septic drain field on only 6.6% of the county's land, so plan on testing your specific parcel closely and budgeting for an engineered system if it doesn't pass21. The land is entirely gentle, with 100% at 15% slope or less, and about 5.6% of the county is federal land2223. Delta County sits about 55 miles from the nearest metro area, and its effective property tax rate runs around 1%, with a median annual bill near $1,456242526. Budget for a typical home insurance premium around $2,178 a year, and confirm driveway, septic and subdivision requirements with Development Services before you close2710.
Watch-outs
Delta County's own website currently blocks automated fetch tools, so this guide couldn't re-verify office phone numbers or addresses directly; call ahead and confirm current contact details through Development Services before you rely on any number you find secondhand10.
Delta County has a Development Services office, unlike many rural Texas counties with no development office at all; don't assume 'no building permit' means 'no permits of any kind' here, since subdivision, driveway/culvert and septic permits all still apply1.
Whether Delta County sits inside a groundwater conservation district that requires well permits hasn't been confirmed on an official source; ask Development Services before you drill rather than assuming either way16.

County-wide zoningAbsent
Texas counties lack general zoning authority in unincorporated areas; Delta County regulates land only through subdivision rules and regulations, not zoning districts.
Industrialized housing or buildings installed in Texas, including purchasers or lessees acquiring a unit for their own or their company’s use.
A person purchasing or leasing an industrialized house or building for their own use or their company’s use may file for an installation permit instead of registering as an industrialized builder.
A person responsible for assembly, connection, and on-site construction for persons other than themselves must be registered as an industrialized builder.
Municipalities may require applicable local permits and licenses before construction begins when the municipality regulates the installation.
“A person who is a retailer of industrialized housing or buildings, or who is responsible for the assembly, connection, and on-site construction and erection of an industrialized house or building for persons other than themselves, must be registered as an industrialized builder. Subcontractors do not require the registration unless required by other applicable state laws. For example, electricians, HVAC contractors, and plumbers must be licensed in accordance with the applicable state law. If you are purchasing or leasing an industrialized house or building for your own use, or your company's use, you may file for an installation permit in lieu of registering as an industrialized builder.”
Owner-builder exemptionConditional
An owner performing electrical, plumbing, or air-conditioning and refrigeration work on the owner's own residence or homestead in Texas.
Electrical work is exempt from state electrician licensing when performed on a dwelling the person owns and resides in.
Plumbing is exempt from state plumbing licensing when performed by the property owner in the property owner's homestead.
Air-conditioning and refrigeration contracting is exempt from the applicable state registration requirements when performed in a building owned solely by the person as the person's home.
These exemptions do not establish a blanket exemption for every construction trade or contractor-regulated activity.
“A person who perform electrical work on a dwelling that they own and reside in is not required by the state to be licensed as electricians.”

Who permits septicMixed (with conditions)
OSSF permitting, inspection, and administration throughout Texas.
TCEQ administers the program in areas where no local jurisdiction has been authorized.
A local governmental entity may administer the program only after an order, ordinance, or resolution is approved by TCEQ.
The authorized agent administers the program within its approved area of jurisdiction.
Local programs may adopt requirements more stringent than state minimums.
“The authorized agent is responsible for the proper implementation of Texas Health and Safety Code, Chapter 366, 30 TAC Chapter 285, including reviewing OSSF permit applications, conducting inspections, investigating complaints, and more.”

“Permits may be required by a GCD for all wells except for wells specifically exempted by a GCD and statutorily-exempt wells (i.e., wells used solely for domestic use or for providing water for livestock or poultry purposes; the drilling of a water well used solely to supply water for a rig actively engaged in drilling or exploration operations for an oil or gas well permitted by the Railroad Commission of Texas (RRC); and the drilling of a water well authorized by the RRC for mining activities).”
Driveway accessRequired
New or modified access driveways connecting property to a Texas state highway right of way.
A local public agency may receive access driveway permitting authority for state highways, but TxDOT approval remains required for drainage impacts on the state highway system before local approval.
No access driveway is permitted within a flared or widened right-of-way section at an intersection of a state highway with another highway, road, or street.
All entrances and exits, including radii, must be confined within the permittee's property frontage.
One-way 45-to-90-degree driveways are permitted for connections to one-way frontage roads or lane-divided highways; otherwise the driveway angle must be 75 to 90 degrees.
ADAAG and Texas Accessibility Standards apply.
private residential driveway maximum width: <= 24 feet (Except as increased by permissible radii.) · driveway-to-pavement radius: >= 15 feet
“A driveway must be constructed in accordance with a fully executed driveway permit”
Permit processPublished (with conditions)
Constructing a new driveway or revising an existing driveway on the right of way of a Texas state highway.
The applicant should contact the local District TxDOT office.
The applicant must submit Form 1058, Permit to Construct Access Driveway Facilities on Highway Right of Way.
The application must be for the bona fide purpose of securing or changing access to the owner's property, not parking or servicing vehicles on state highway rights of way.
No construction may begin on the right of way until a fully executed driveway permit is received and the applicant gives TxDOT 24-hour notification.
The driveway must comply with the executed permit and applicable regulations; TxDOT inspection must find construction satisfactory.
Where a local public agency has permitting authority, drainage impacts on the state highway system still require TxDOT approval before local approval.
Driveway geometrics, utilities, environmental requirements, wetlands considerations, ADAAG, TAS, and other applicable state and federal laws must be considered.
required form: Form 1058, Permit to Construct Access Driveway Facilities on Highway Right of Way · advance notification: 24 hours (Notification to TxDOT is required before construction on the right of way.) · private residential driveway maximum width: <= 24 feet (Except as increased by permissible radii.) · minimum driveway radius to highway pavement: >= 15 feet
“The applicant shall complete and submit to TxDOT a Form 1058”
county zoning authorityLimited
Texas counties adopting zoning regulations for specified unincorporated or otherwise specially defined areas.
Chapter 231 does not grant a general statewide county zoning power; authority is provided through geographically or subject-matter limited subchapters.
For Padre Island, the authority applies in Cameron or Willacy County outside a municipality and within two miles of a publicly owned park or recreational development, or within two miles of a beach, wharf, or bathhouse used by at least 500 persons annually.
Other Chapter 231 subchapters address special areas including the Amistad Recreation Area in Val Verde County, military zones, certain lakes, the El Paso Mission Trail Historical Area, Lake Somerville, and Falcon Lake in Zapata County.
The cited statute was enacted effective September 1, 1987; the Falcon Lake subchapter was added effective June 15, 2007, and amended effective September 1, 2009.
Padre Island distance from publicly owned park or recreational development: <= 2 miles (Area must be outside a municipality and in Cameron or Willacy County.) · Padre Island distance from beach, wharf, or bathhouse: <= 2 miles (The beach, wharf, or bathhouse must be used by at least 500 persons annually.)
“This subchapter applies to the areas of Padre Island located in Cameron or Willacy County and located: (1) outside a municipality but within two miles of a publicly owned park or recreational development; or (2) within two miles of a beach, wharf, or bathhouse used by at least 500 persons annually.”

Limited — County zoning authority over unincorporated land in Texas, where a specific statutory grant applies.
“As you suggest, a county has very limited and specific zoning authority, and none that may be used to regulate construction or operation of the proposed facility.”
county building authorityLimited
Texas counties adopting and enforcing fire-code building permits for specified buildings in unincorporated areas and applying residential building-code standards in certain counties.
Under Section 233.061, the county must have a population over 250,000 or be adjacent to a county with a population over 250,000.
Under Section 233.062, the fire code applies only to commercial establishments, public buildings, and multifamily residential dwellings consisting of four or more units constructed in an unincorporated area.
The fire code does not apply to an industrial facility having a fire brigade that conforms to Occupational Health and Safety Administration requirements.
A covered applicant must submit a plan and a commissioners-court-set application fee; the county must issue or deny the permit within 30 days, and failure to act within 30 days approves the construction for purposes of the subchapter.
The fire code must conform to the International Fire Code or Uniform Fire Code as those codes existed on May 1, 2005, or establish protective measures exceeding those standards; later editions may be adopted.
Residential standards under Section 233.152 apply only if the county adopts a resolution or order and the county is within 50 miles of an international border or has a population over 100.
Those residential standards apply only to new single-family-house or duplex construction beginning after September 1, 2009; manufactured or modular structures governed by Occupations Code Chapters 1201 or 1202 are excluded from the definition of new residential construction.
A municipality's building code controls in its extraterritorial jurisdiction, and Section 233.152 does not authorize county prior approval of new residential construction or county zoning regulations.
Fire-code inspection and permit fees may be charged under a fee schedule based on building type, limited to amounts necessary to administer and enforce the subchapter; inspection fees must be reasonable and reflect approximate inspection costs.
county population threshold for fire-code authority: > 250000 persons (A county adjacent to a county over 250,000 also qualifies.) · multifamily residential dwelling threshold: >= 4 units (The fire code applies only to covered buildings constructed in an unincorporated area.) · residential-code border distance: <= 50 miles (Alternative qualification is county population over 100.) · application decision period: 30 days (If the commissioners court does not issue or deny the permit within 30 days after receiving the application and fee, construction is approved for purposes of the subchapter.) · residential standards effective construction date: > 2009-09-01 (Applies only to new residential construction that begins after September 1, 2009.)
“The commissioners court of a county with a population of over 250,000 or a county adjacent to a county with a population of over 250,000 may adopt a fire code and rules necessary to administer and enforce the fire code. [...] The fire code applies only to the following buildings constructed in an unincorporated area of the county: (1) a commercial establishment; (2) a public building; and (3) a multifamily residential dwelling consisting of four or more units.”
