Building permits, zoning and septic rules in Orange County, Texas

#61 of 254 in Texas

Unincorporated Orange County, Texas has no zoning ordinance, but it still requires a development permit for any building constructed or moved onto a property, including a new home, an addition, or a manufactured home12. Any building with living quarters also needs three inspections under Texas HB 2833: foundation, framing/mechanical, and completion3. The same Environmental Health and Code Compliance Department issues both the development permit and the septic (OSSF) permit34.

Do you need a building permit in Orange County, Texas?

Unincorporated Orange County, Texas requires a development permit for any building constructed or moved onto a property, or for an improvement worth more than half the value of an existing building23. The county's own list of what triggers a permit is broad: a new home, an addition, a manufactured or mobile home placed on the land, a temporary residential or commercial building, an agriculture building, and fill, grading, excavation, mining or dredging all need one3. Any building with living quarters also has to pass three inspections under Texas House Bill 2833: a foundation inspection before concrete is poured, a framing and mechanical inspection before drywall goes up, and a final completion inspection3. Those inspections must be done by a licensed engineer, a registered architect, a Texas Real Estate Commission-licensed inspector, a licensed plumbing inspector, or a certified residential combination inspector3.

Who is the Orange County building department, and how do you reach them?

Development and floodplain permits in Orange County go through the Environmental Health and Code Compliance Department at 11475 FM 1442, Orange, TX 77630, phone (409) 745-14633. The office is open Monday through Friday, 8:00am to 5:00pm3. Once you submit a development permit application, the department determines what FEMA flood zone the property sits in, and that determines how high you'll need to build3. If the parcel is in Flood Zone A, you'll also need to provide the department with an elevation certificate before the permit is issued3. The same department, at the same address and phone number, also issues septic (OSSF) permits4.

Does Orange County have zoning?

Orange County has no zoning ordinance; the county administers development and floodplain permits, not zoning districts1. Texas gives most counties no general zoning power at all, and Orange County is not one of the narrow exceptions the state legislature has carved out for specific areas like Padre Island or the Amistad Recreation Area6. Because there is no zoning, the county sets no minimum home size, minimum lot size, setback, lot-coverage limit, or building-height limit by ordinance, and doesn't restrict RVs, tiny homes, manufactured homes or accessory dwellings by zoning6. That doesn't mean anything goes: the development-permit rule above still applies, and placing a manufactured home or a temporary residential building is explicitly one of the things that triggers a permit23.

How do septic permits work in Orange County?

Every new on-site sewage facility (OSSF, commonly called septic) in unincorporated Orange County must be permitted through the Environmental Health and Code Compliance Department before installation begins45. The county's own guidance is to start by contacting a septic installer licensed by the State of Texas, who can help assemble the paperwork the permit application needs4. Statewide, Texas requires a permit and approved plan to construct, alter, repair or extend an OSSF, though a 10-acre exemption can apply if a licensed site evaluator or engineer signs off, the tract has a single-family home on at least 10 acres, all system parts sit at least 100 feet from the property line, and effluent stays on the property9. Because Orange County's own department, not a separate district, issues the permit here, that's who to call with soil or site questions before you buy4.

Can you live in an RV or tiny home on your land in Orange County?

Because unincorporated Orange County has no zoning, there's no zoning-based restriction on living in an RV, a tiny home, or a manufactured home on your own land6. That's not the whole picture, though: the county's development-permit rule specifically lists placing a manufactured or mobile home, and putting up a temporary building for residential use, as things that require a development permit before you move in23. If the structure has living quarters, plan on the same three HB 2833 inspections that apply to a stick-built home: foundation, framing/mechanical, and completion3. Confirm with the Environmental Health and Code Compliance Department how they'll treat your specific RV or tiny-home setup before you buy or move one in3.

Building a home in Orange County: the steps, in order

  1. Contact the Orange County Environmental Health and Code Compliance Department (409-745-1463) before you buy, to confirm the flood zone and what the development permit will require3.
  2. Submit a development permit application for the new home; permits are valid for one year once issued3.
  3. If the parcel is in Flood Zone A, provide an elevation certificate as part of the permit process3.
  4. Line up a licensed engineer, registered architect, TREC-licensed inspector, licensed plumbing inspector, or certified residential combination inspector to perform the foundation, framing/mechanical, and completion inspections HB 2833 requires for any building with living quarters3.
  5. Contact a Texas-licensed septic installer and apply for an OSSF permit through the same Environmental Health and Code Compliance Department if the property isn't on sewer4.
  6. If your driveway will connect to a state highway rather than a county road, apply to TxDOT for a driveway permit on Form 1058 before you build it8.

What to check before you buy land in Orange County

Confirm the flood zone with the Environmental Health and Code Compliance Department before you buy: Flood Zone A land needs an elevation certificate and will affect how high you have to build3. Ask the same office what OSSF site evaluation your soils will need, since Texas's statewide 10-acre exemption only removes the permit requirement if every one of its conditions is met, including a licensed site evaluator's sign-off and 100 feet of clearance from the property line for the whole system9. Orange County averages 61.4 inches of annual precipitation and sits at a wooded 53.3% forest cover, so expect wetter soils than much of Texas when you're planning a septic field1011. If your access road will tie into a state highway, budget time for a separate TxDOT driveway permit on top of the county's process8. There's no county zoning to check on a specific parcel, so verify any deed restrictions or subdivision covenants directly with the title company, since those can be more restrictive than anything the county requires6.

Watch-outs

  • Orange County's own page does not state whether an owner-builder exemption applies to the development permit or the inspections it requires; ask the Environmental Health and Code Compliance Department directly before you plan to self-build73.
  • A development permit is only valid for one year, so time your application to when you're actually ready to start construction3.
