Building permits, zoning and septic rules in Ector County, Texas
41Index Score / 100 #192 of 254 in Texas
Unincorporated Ector County, Texas requires Development Structure and Drive Approach permits for a dwelling or business, but the structure permit addresses finished-floor elevation rather than comprehensive structural plan review12. The county does not enforce zoning in unincorporated areas, though the City of Odessa zones land inside the city34. Septic permits for installing or repairing a system come from Ector County Development Services5.

Do you need a building permit in Ector County, Texas?
Unincorporated Ector County requires Development Structure and Drive Approach permits for a dwelling or business12. The structure permit requires the finished floor to be at least 1 foot above the road crown or curb, while the Drive Approach permit is valid for 6 months12. The county sources do not establish comprehensive structural plan review or general building inspections for ordinary dwellings or businesses; Ector County may, however, inspect manufactured-home rental-community infrastructure during or after construction12. Ector County does not issue county certificates of occupancy in unincorporated areas, though an MHRC may separately need a Certificate of Compliance713. General county permits have no charge, but subdivision-development review has separate fees due before review8.
Who issues building, driveway and septic permits in Ector County, and how do you reach them?
Reach Ector County Development Services at 1010 E 8th Street, Suite 114, Odessa, Texas 79761, by phone at (432) 498-4241, or by email at development.services@ectorcountytx.gov1415. Send permit applications, site plans and attachments to Development Services by email with the property address in the subject line16. The office handles Development Structure, Drive Approach, Septic, Right-of-Way and Tower permits15. A Right-of-Way permit is needed for work within a county right-of-way, and a Tower permit is required for tower construction or modification1514. Use the county permit path for an approach to a county road; a new or revised driveway on a state-highway right-of-way instead requires a TxDOT application211.
Does Ector County have zoning?
Ector County does not enforce development zoning in unincorporated areas, but the City of Odessa administers zoning within Odessa34. On unincorporated land, county zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit or building-height limit, and county zoning does not restrict RV, tiny-home, manufactured-home or accessory-dwelling occupancy9. No county zoning does not mean no land rules: Development Structure, driveway, septic, subdivision, manufactured-home rental-community and floodplain requirements can still apply3. Dividing unincorporated land into subdivisions or lots generally requires a plat approved by the Commissioners Court before recordation10.
How do septic permits work in Ector County?
Ector County administers septic permitting and requires a permit to install or repair an on-site sewage facility65. Construction must wait for approval, and unauthorized work can bring civil or administrative penalties5. About 27.8% of Ector County soils are rated without severe limits for a conventional drain field, so evaluate the actual homesite rather than assuming a conventional system will work17. A narrow state exemption can apply to a single-family home on at least 10 acres only when a licensed site evaluator or engineer approves the site, the home is the tract's only dwelling and every part of the system remains at least 100 feet from the property line18. The county's general permit schedule is free, while subdivision review can carry separate fees8.
Can you live in an RV or tiny home on your land in Ector County?
Ector County zoning does not restrict RV, tiny-home or manufactured-home occupancy on unincorporated land9. That answer is limited to county zoning: a dwelling or business still needs the county's Development Structure and Drive Approach permits, and a septic system still needs approval125. Covered subdivisions and manufactured-home rental communities must plan for water, sewer, septic and utility infrastructure under the applicable public or private service rules19. An MHRC utility may not start water, sewer, gas or electric service without the owner's county-issued Certificate of Compliance13. Inside Odessa, municipal zoning applies, so do not carry the unincorporated-county answer across the city limit4. Texas also exempts a person from state electrician licensing for electrical work on a dwelling the person owns and lives in, but that licensing exemption does not waive a locally administered permit or inspection20.
How do you build a home in Ector County, step by step?
Confirm whether the parcel is inside a municipality or in unincorporated Ector County; Odessa has municipal zoning, while the county does not zone unincorporated land21.
Email the Development Structure application, site plan and attachments to Ector County Development Services with the property address in the subject line16.
Plan for the finished floor to sit at least 1 foot above the road crown or curb1.
Obtain a Drive Approach Permit for a county-road connection; use TxDOT's Form 1058 process for a state-highway connection211.
Secure county approval before installing or repairing the septic system5.
If the project divides unincorporated land, obtain Commissioners Court plat approval before recordation and pay applicable subdivision-review fees108.
What should you check before buying land in Ector County?
Confirm water service before closing: Ector County averages 13.5 inches of precipitation a year and has spent about 30% of recent years in severe drought2223. We could not confirm a countywide private-well permit rule, so ask the water provider or groundwater district serving the parcel. Only about 27.8% of county soils are rated without severe limits for a conventional drain field, and septic installation requires county approval175. For land in a covered subdivision, check plat status and the applicable water, wastewater and utility plan before relying on a proposed homesite1019. For access, identify whether the frontage is a county road or state highway because the permit path changes211. The effective property-tax rate is about 1.3%, with a median annual bill near $2,4382425. On a subdivision lot that includes land in a designated 100-year flood hazard zone, the owner must contact the Ector County Floodplain Administrator to request a floodplain development permit before building26. A well inside a groundwater conservation district generally needs that district's permit, so ask the district serving the parcel27.
Watch-outs
Ector County's Development Structure and Drive Approach permits still apply to dwellings or businesses in unincorporated areas even though the county does not enforce development zoning there31.
General county permits are free, but subdivision-development review has a separate fee schedule that must be paid before review8.
A manufactured-home rental community may need infrastructure inspections and a Certificate of Compliance before utilities can connect service; that rule does not establish a general inspection program for an individual home1213.

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.

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.”
