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 review1. The county does not enforce zoning in unincorporated areas, though the City of Odessa zones land inside the city2,3. Septic permits for installing or repairing a system come from Ector County Development Services2.
Do you need a building permit in Ector County, Texas?
Unincorporated Ector County requires Development Structure and Drive Approach permits for a dwelling or business.
Unincorporated Ector County requires Development Structure and Drive Approach permits for a dwelling or business1. 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 months1. 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 construction5. Ector County does not issue county certificates of occupancy in unincorporated areas, though an MHRC may separately need a Certificate of Compliance2,5. General county permits have no charge, but subdivision-development review has separate fees due before review5.
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.gov.
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.gov1,2. Send permit applications, site plans and attachments to Development Services by email with the property address in the subject line1. The office handles Development Structure, Drive Approach, Septic, Right-of-Way and Tower permits1. 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 modification1,2. 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 application1,7.
Does Ector County have zoning?
Ector County does not enforce development zoning in unincorporated areas, but the City of Odessa administers zoning within Odessa.
Ector County does not enforce development zoning in unincorporated areas, but the City of Odessa administers zoning within Odessa2,3. 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 occupancy6. No county zoning does not mean no land rules: Development Structure, driveway, septic, subdivision, manufactured-home rental-community and floodplain requirements can still apply2. Dividing unincorporated land into subdivisions or lots generally requires a plat approved by the Commissioners Court before recordation5.
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 facility.
Ector County administers septic permitting and requires a permit to install or repair an on-site sewage facility2,4. Construction must wait for approval, and unauthorized work can bring civil or administrative penalties2. 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 work8. 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 line9. The county's general permit schedule is free, while subdivision review can carry separate fees5.
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 land.
Ector County zoning does not restrict RV, tiny-home or manufactured-home occupancy on unincorporated land6. 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 approval1,2. Covered subdivisions and manufactured-home rental communities must plan for water, sewer, septic and utility infrastructure under the applicable public or private service rules5. An MHRC utility may not start water, sewer, gas or electric service without the owner's county-issued Certificate of Compliance5. Inside Odessa, municipal zoning applies, so do not carry the unincorporated-county answer across the city limit3. 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 inspection10.

- Confirm whether the parcel is inside a municipality or in unincorporated Ector County; Odessa has municipal zoning, while the county does not zone unincorporated land2.
- Email the Development Structure application, site plan and attachments to Ector County Development Services with the property address in the subject line1.
- 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 connection1,7.
- Secure county approval before installing or repairing the septic system2.
- If the project divides unincorporated land, obtain Commissioners Court plat approval before recordation and pay applicable subdivision-review fees5.
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 drought.
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 drought8. 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 approval2,8. For land in a covered subdivision, check plat status and the applicable water, wastewater and utility plan before relying on a proposed homesite5. For access, identify whether the frontage is a county road or state highway because the permit path changes1,7. The effective property-tax rate is about 1.3%, with a median annual bill near $2,4388. 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 building5. A well inside a groundwater conservation district generally needs that district's permit, so ask the district serving the parcel11.
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 there1,2.
- General county permits are free, but subdivision-development review has a separate fee schedule that must be paid before review5.
- 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 home5.
