Building permits, zoning and land rules in Jeff Davis County, Texas

#117 of 254 in Texas

Unincorporated Jeff Davis County, Texas does not require a building permit for a home, and Texas law gives the county no general zoning authority, so there is no county minimum lot size, setback, or restriction on living in an RV, tiny home or manufactured home on your own land12. Septic is the exception: Jeff Davis County itself is the state's authorized agent for on-site sewage facility (OSSF) permits in the unincorporated county, so that permit comes from the county, not directly from the state3.

Do you need a building permit in Jeff Davis County, Texas?

No. Jeff Davis County does not require a building permit for an ordinary single-family home in its unincorporated area and has no building department to issue one1. A separate Texas residential-code provision can apply only after a qualifying county adopts it by resolution or order; we could not confirm that Jeff Davis County has done so8. If that provision applies, a new residence on a vacant lot must receive foundation, framing-and-mechanical, and final inspections, with the builder hiring an authorized inspector; additions are inspected as their scope requires9. Because Jeff Davis County has no county building permit, it publishes no owner-builder permit exemption; the state inspection law instead gives a narrow penalty protection to a person building or contracting a primary residence who fails to submit the required notice59.

Who handles building, zoning and septic permits in Jeff Davis County, and how do you reach them?

There is no building, planning or zoning department in unincorporated Jeff Davis County14. The Jeff Davis County Judge's Office at the county courthouse in Fort Davis handles general county administration, and it is the office to start with for anything the website doesn't list a specific department for, including septic (OSSF) permit questions10. The Jeff Davis County Clerk records deeds, plats and other official public records11. The Jeff Davis County Tax Assessor-Collector handles property tax assessment and collection12.

Does Jeff Davis County have zoning?

No. Texas lets counties zone only in a short list of specific places, and Jeff Davis County is not on it, so the county has no general zoning authority over unincorporated land13. With no county zoning ordinance, Jeff Davis County sets no minimum home size, no minimum lot size, no setbacks, and no lot-coverage or building-height limit, and it does not restrict accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping on your own unincorporated land2. That applies to unincorporated county land only: if a parcel is inside Valentine or Fort Davis, ask that community about its own rules, because we could not confirm what they are4. Septic stays with the county either way: OSSF permits do not move to a town3.

How do septic permits work in Jeff Davis County?

Jeff Davis County is the authorized agent for septic (OSSF) permits in the unincorporated county, while TCEQ's Region 06 office in El Paso covers areas outside that authority3. Submit the application and planning materials to the permitting authority before constructing, altering, repairing, extending or operating a septic system or holding tank; the authority must approve or deny a complete submission within 30 days of receipt14. A single-family home on at least 10 acres may avoid the permit only after a licensed site evaluator or professional engineer confirms every condition, including a 100-foot property-line separation, on-property effluent disposal, no nuisance or groundwater pollution, and no other dwelling on the tract15. An owner may install the system for a single-family home the owner owns, but only if the permitting authority allows owner installation16. We could not find a Jeff Davis County OSSF fee schedule; the state's $10 fee is only what an authorized agent collects and reports, not the full local fee, so ask the County Judge's Office what the county charges1710. Only about 11.7% of county soils lack severe limitations for a conventional drain field, so arrange the site evaluation before assuming a standard system will work18. Systems using secondary treatment or drip irrigation require inspection every four months, although qualifying single-family homeowners may maintain their own systems; that rule does not cover every conventional system19.

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

Yes, on unincorporated county land: Jeff Davis County does not use zoning to restrict RV, tiny-home or manufactured-home occupancy on private land2. Texas law does not give Jeff Davis County general zoning power over that land13. Off-grid living still requires lawful wastewater disposal: an OSSF generally needs a permit and approved plan, and the exemption for a single-family home on at least 10 acres applies only when every site-evaluation, setback, groundwater, nuisance, effluent-disposal and single-dwelling condition is met15. Inside Valentine or Fort Davis, ask that community directly because local rules may differ and we could not confirm them4.

How do you build a home in Jeff Davis County, Texas, step by step?

  1. Confirm the parcel is in unincorporated Jeff Davis County rather than inside Fort Davis or Valentine city limits, where municipal rules may apply4.
  2. No county building permit is required, but ask the County Judge's Office whether the state residential inspection provision has been adopted for your project before work begins1910.
  3. Submit the OSSF application and plan to Jeff Davis County, or document that every condition of the 10-acre exemption is met; the permitting authority has 30 days from receipt to approve or deny the materials314.
  4. For a new or changed driveway onto a state highway, submit Form 1058 through the local TxDOT district office and wait for the executed permit before entering the right of way20.
  5. Contact the Jeff Davis County Clerk if you need to record a deed, plat or new legal description11.
  6. Ask the Tax Assessor-Collector how the parcel is assessed and how improvements may affect the tax bill12.

What should you check before buying land in Jeff Davis County, Texas?

Get the septic picture early: only about 11.7% of Jeff Davis County soils lack severe limitations for a conventional drain field, so arrange a site evaluation before assuming a standard system will work18. Annual precipitation averages about 14.2 inches, and severe drought occurs in roughly 31.2% of years, so confirm the water source and expected well yield before committing2122. Jeff Davis County has about 0.8 people per square mile and roughly 1,856 residents, while the nearest city of 100,000 or more is about 134 miles from the county center232425. A new or modified entrance onto a state highway needs a TxDOT permit, and right-of-way construction cannot begin until the executed permit is received and TxDOT receives 24-hour notice20. Land that has been devoted to agricultural use for at least five of the past seven years may qualify for agricultural appraisal, which lowers the tax bill; ask the county appraisal district whether a parcel already holds it, because converting it to non-agricultural use can trigger rollback taxes26. The effective property-tax rate is about 0.5%, with a median annual bill near $1,28367.

Watch-outs

  • We could not confirm whether Jeff Davis County adopted the state residential inspection provision or requires a certificate of occupancy; ask the County Judge's Office before construction begins910.
  • Jeff Davis County's website does not publish a dedicated environmental health or OSSF department; start septic questions with the County Judge's Office rather than assuming a specific office exists10.
  • This page covers unincorporated Jeff Davis County only. Valentine and Fort Davis may have their own local rules, and no official source we found states what they are; septic permits stay with the septic permitting authority either way43.

Texas rules that apply here

  • Building permitLimited

    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

    “This depends on whether the permitting authority allows this in their local requirements. Otherwise yes, provided you have the knowledge, skills, and equipment to do so AND: the OSSF is for a single family dwelling that you own, you also own the property, no part of the property will be developed for sale or lease, all permitting, construction, and maintenance requirements of the permitting authority are met.”
