Do you need a building permit in Hemphill County, Texas?
Unincorporated Hemphill County does not require a general county building permit for an ordinary site-built home1. Industrialized and modular housing is different: state installation or alteration requirements can apply outside a municipality11. A qualifying purchaser installing an industrialized house or residential modular component for personal use may obtain a residential installation permit instead of registering as an industrialized builder; that state permit does not waive inspections or mandatory codes12. Inside Canadian, the city requires a building permit before work covered by its building code begins; the cited code provision covers buildings other than single-family residential structures, so ask the city what code and permit process applies to a house3. Septic permits still go through TCEQ Region 1, and wells still go through the Hemphill County Underground Water Conservation District56.
Who issues building, septic and road permits in Hemphill County?
Hemphill County has no general building-permit or inspection department for ordinary site-built homes in unincorporated areas1. Canadian issues city building permits for work governed by its building code and publishes a city permit-fee schedule; its separate street-cut repair fees apply to utility or licensed-plumber cuts within the city, not rural construction313. TCEQ Region 1 issues septic permits throughout Hemphill County because there is no local OSSF agent514. The County Judge's Office handles underground crossings, road cuts and waterline crossings on county roads1516. A driveway connecting to a state highway requires TxDOT approval17. We could not confirm a county-road driveway or culvert rule, so ask the County Judge's Office about access before construction16.
Does Hemphill County have zoning?
Unincorporated Hemphill County has no county zoning, so the county does not set zoning districts, minimum dwelling size, minimum lot size, setbacks, lot coverage or building height there2. That answer does not erase septic, well, subdivision, floodplain, deed-restriction or access requirements. Inside Canadian, municipal zoning applies, and the city uses a variance process4. Canadian also requires building permits for work covered by its adopted building code, while septic permits remain with TCEQ Region 1 and wells remain with the Hemphill County Underground Water Conservation District356. For land outside another incorporated municipality, confirm city-limit and extraterritorial-jurisdiction status before assuming the unincorporated-county answer controls9.
How do septic permits work in Hemphill County?
A septic permit and approved plan are generally required to construct, alter, repair, extend or operate an on-site sewage facility in Hemphill County7. TCEQ Region 1 is the permitting authority because Hemphill County has no local OSSF agent514. The state exemption for a qualifying large tract applies only when every condition is met, including a licensed site evaluation, a single-family dwelling as the only dwelling on the tract, no nuisance or groundwater pollution, on-property effluent disposal and the required property-line separation18. Grandfathered systems and specified emergency repairs have separate limited exceptions18. Only 32.9% of county soils are free of severe limitations for a conventional drain field, so obtain the site evaluation before fixing the house location19.
Can you live in an RV or tiny home on your land in Hemphill County?
Unincorporated Hemphill County has no county zoning restriction on tiny-home or manufactured-home occupancy, but that does not answer sanitation, floodplain, deed-restriction or utility requirements2. We could not confirm a rule that answers long-term RV occupancy on unincorporated private land; ask the County Judge's Office before using an RV as a residence16. The county's published RV limits cover public campgrounds, not private property8. Inside Canadian, city zoning applies to the parcel, while septic permits still go through TCEQ Region 1 and wells still go through the water district456. An RV, tiny home or manufactured home using an OSSF generally needs septic approval unless a state exception applies7.
Building a home in Hemphill County: the steps, in order
Confirm whether the parcel is inside Canadian or another municipality; unincorporated Hemphill County has no general county building permit or county zoning, while Canadian has city zoning and building-permit rules1243.
Confirm the tract was legally divided. State law generally requires a subdivision plat outside municipalities, while a qualifying agricultural, farm, ranch, wildlife-management or timber-production division may be exempt910.
Ask TCEQ Region 1 for the septic permit process and arrange the site evaluation714.
Register an exempt well or obtain the applicable district permit before drilling6.
Obtain TxDOT approval for state-highway access or county approval for an underground crossing, road cut or waterline crossing1715.
If the project uses industrialized or modular housing, confirm the separate state requirements before installation11.
What should you check before buying land in Hemphill County?
Start with septic suitability: only 32.9% of Hemphill County soils are free of severe limitations for a conventional drain field19. Confirm that a divided tract has any required plat approval and tax certificate; an agricultural-use plat exemption is limited and does not remove septic, floodplain, water-district or municipal rules2010. Plan water before closing because every new exempt or non-exempt well must be registered or permitted through the Hemphill County Underground Water Conservation District before drilling6. The county averages 23.3 inches of precipitation a year and experiences severe drought in 32.3% of years2122. The effective property-tax rate is about 1.2%, with a median annual bill near $2,5022324.
Watch-outs
Do not use the septic form posted on Hemphill County's website: it is labeled for Hill County; Hemphill County septic permits go to TCEQ Region 1514.
Canadian's building permits and zoning apply inside the city; septic permits remain with TCEQ Region 1 and wells remain with the Hemphill County Underground Water Conservation District3456.
The county's public-campground rules do not answer whether an RV may be occupied long term on private land; ask the County Judge's Office816.

What the ordinances and state agencies actually say — one answer per question, each quoted from the official source and independently re-checked.
Hemphill County rules
Local zoningVaries (with conditions)
Aggregate conclusion for local zoning within Hemphill County; incorporated municipalities may administer their own zoning rules, while this claim does not attribute each municipal ordinance to the county.
The official source confirms zoning regulation within the City of Canadian; applicability depends on whether property is within Canadian or another local jurisdiction.
The source concerns a zoning variance and does not establish countywide zoning in unincorporated Hemphill County.
“The zoning variance would apply to the following described property. Section 77, Block 42, H & TC. The address is: 1 Main Street, Canadian, Texas 79014 Hemphill County, Texas.”

Well permitLimited
New exempt and non-exempt groundwater wells constructed within the boundaries of the Hemphill County Underground Water Conservation District, whose boundaries are coterminous with Hemphill County.
The District requires each new exempt or non-exempt well within its boundaries to be registered or permitted under District rules.
Domestic, livestock, rig-supply, monitoring, and Texas Water Code §36.121 wells covered by the exempt-well subchapter must be registered.
Exempt wells do not require a production permit but remain subject to District registration and production limitations.
Existing and new domestic and livestock wells are limited to beneficial use without waste or no more than 50,000 gallons per day (35 gallons per minute), whichever is less.
An exempt well loses its exemption if its nature changes so it no longer qualifies; the owner must notify the District in writing within 30 days of changed circumstances.
A non-exempt well requires the applicable District permit under the District rules.
domestic or livestock exempt-well production limit: <= 50000 gallons per day (or beneficial use without waste, whichever is less) · domestic or livestock exempt-well flow limit: <= 35 gallons per minute (alternative expression of the 50,000-gallon-per-day limit) · changed-circumstances notice: <= 30 days (after facts that may cause loss of exemption)
“Each year, the District will require all new exempt or non-exempt wells that are constructed within the boundaries of the District to be registered or permitted with the District in accordance with the District Rules.”

“Yes, all wells are to be registered or permitted through the District and all new wells must be registered or permitted prior to drilling.”
Agricultural exemptionAvailable
Exemption from county subdivision plat requirements for qualifying land divisions outside municipal limits in Hemphill County.
The land must be used primarily for agricultural use as defined by Section 1-d, Article VIII, Texas Constitution, or for farm, ranch, wildlife-management, or timber-production use within Section 1-d-1, Article VIII, Texas Constitution.
The owner must divide the tract into two or more parts without laying out a part of the tract described by Local Government Code Section 232.001(a)(3).
If the tract ceases to be used primarily for the qualifying use, the platting requirements apply.
The exemption concerns subdivision platting; it does not eliminate other applicable requirements such as septic, floodplain, water-district, or municipal/ETJ rules.

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.

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.”

Building code adoptedPartial
Buildings and structures within the City of Canadian other than single-family residential structures.
The adopted code is the 2018 edition of the International Building Code.
A copy of the IBC must be kept in the city secretary’s office and made available for public inspection during normal business hours.
The code is amended to insert City of Canadian, Texas; a fee schedule is attached for Section 108.2; City of Canadian, Hemphill County, Texas and specified dates are inserted into Section 1612.3; and October 21, 2019 is inserted into Section 3410.2.
A building permit is required for work that must conform to the city building code, including construction, enlargement, alteration, improvement, removal, relocation, or demolition; work may not begin before the permit is obtained from city hall.
