Do you need a building permit in El Paso County, Texas?

Not a conventional one. El Paso County does not issue conventional building permits in unincorporated areas, but covered residential construction still requires notice and inspection14. El Paso County's residential program took effect in 2013 for new single-family homes, duplexes, and additions that increase a home's square footage or value by more than 50%14. A builder, contractor, or owner must file a Commencement of Residential Construction notice before work begins14. Third-party inspections are required before foundation concrete, before framing and mechanical systems are covered, and at completion2. El Paso County does not perform those inspections; qualifying inspectors include Texas-licensed engineers or architects, TREC inspectors, plumbing or building inspectors, and IRC-certified code inspectors2. The county does not issue a certificate of occupancy, although an Emergency Service District or municipality may have a separate requirement15.

Who handles permits in El Paso County, and how do you reach them?

For septic, driveway, road-cut, floodplain, and plat-compliance permits, contact El Paso County Planning and Development at 915-273-3330 or visit 800 E Overland Suite 200, El Paso, TX 7990116. The county identifies Accela as its permit and application submission portal6. For residential construction registration, contact the Public Works Department at (915) 546-2015; the Commencement of Residential Construction form is available at 800 E. Overland St, Suite 40717. El Paso County directs people seeking building-permit guidance in unincorporated areas to Emergency Service District #1 or #218. Before applying, confirm the parcel is outside a municipality because city requirements are separate from county requirements6.

Does El Paso County have zoning?

Not in unincorporated areas, with two narrow exceptions. El Paso County's own FAQ states there are no zoning requirements for land in unincorporated areas unless it sits near Fabens Airport or the Historic Mission Trail, and the county does not publish the specific district names, boundaries, or numeric standards that apply in those two exception areas4. Texas law backs this up: Chapter 231 of the Local Government Code gives counties zoning power only for specific, named places such as Padre Island in Cameron or Willacy County, the Amistad Recreation Area, certain lakes, and the El Paso Mission Trail Historical Area, not a general county zoning power19. That absence of zoning means unincorporated El Paso County sets no minimum home size, minimum lot size, building setback, lot-coverage limit, or building-height limit89102021. It does not mean unregulated land division, though: subdividing land outside a city into two or more residential lots of five acres or less still requires preliminary and final plat approval from the County Engineer and Commissioners Court before it can be recorded22. Remember this only covers unincorporated land; the City of El Paso runs its own zoning section that reviews projects, rezoning requests, and setback relief inside city limits23.

How do septic permits work in El Paso County?

El Paso County Planning and Development administers OSSF permits and inspections in unincorporated areas24. Before building, verify whether public sewer is available; if it is not, a septic system is required25. A permit and approved plan are generally required to construct, install, alter, extend, repair, or operate an OSSF26. A possible exemption applies on tracts of at least 10 acres only when every condition is met, including a qualifying site evaluation, one dwelling, all system parts at least 100 feet from a property line, and on-site effluent disposal26. Only 34.1% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation part of due diligence13. Texas recognizes approved composting toilets, but all other wastewater still needs an approved OSSF, and product approval does not approve a particular site27. For a private well, El Paso County requires a certified-laboratory test as the potable-water alternative to metered service, but we could not confirm a countywide well-permit rule; ask Planning and Development2516.

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

Unincorporated El Paso County has no zoning ordinance, so accessory dwelling units, tiny homes, and manufactured homes are unrestricted by county zoning, since Texas law gives zoning power only to counties like El Paso in specific named areas and the county has none of the general kind7. Long-term or permanent RV occupancy on privately owned land is a real gap, though: no official county source, including the Permits page, Plan Review materials, or floodplain rules, establishes whether living in an RV on your own unincorporated land is allowed, limited, or prohibited. The one RV rule the county does publish only covers county-owned property: tents and RVs can't be used or occupied on El Paso County property after regular business hours (8:00 a.m. to 5:00 p.m. each county business day, weekends and holidays excluded) without written authorization, and that rule says nothing about private land28. Before counting on RV or tiny-home living as a strategy, call Planning and Development directly to confirm there's no unwritten practice or code-enforcement position on the subject16.

Building a home in El Paso County: the steps, in order

First, confirm your parcel is unincorporated and not inside the City of El Paso, Socorro, or Horizon City, since none of the county's rules below apply inside those cities29. Second, check whether the property is in a County-adopted special flood hazard area; if it is, get a floodplain determination letter and a Floodplain Development Permit from Planning and Development, prepared with a Texas-licensed engineer or surveyor12. Third, verify your water source (metered public water or a lab-tested well) and whether public sewer reaches the lot; if not, plan your OSSF and apply for a septic permit through Planning and Development255. Fourth, if you're building a new single-family home or duplex, or an addition growing the home by more than 50% in size or value, file the Commencement of Residential Construction notice with Public Works before starting work1730. Fifth, schedule your third-party inspections at the foundation, framing/mechanical, and completion stages to comply with that same order30. Sixth, if you need a new driveway or road cut, get that permit through Planning and Development's Accela portal before construction31. Seventh, if your driveway connects to a state highway, apply separately to TxDOT using Form 1058 and give 24-hour notice before construction32.

What to check before you buy land in El Paso County

Water is the first question in this part of Texas: El Paso County gets only about 9.5 inches of rain a year, with severe drought in nearly 20% of years, so confirm your water source and its reliability before you commit3334. Soils are comparatively workable for septic, with 34.1% free of severe limitations for a conventional drain field, but still budget for a site evaluation13. Terrain is mostly gentle, with 85.6% of the county at 15% slope or less, though only 2.9% of land is wooded, so expect open desert rather than tree cover3536. Check whether the parcel is in a County-adopted special flood hazard area and whether it's near Fabens Airport or the Historic Mission Trail, the two places where county zoning-style rules can apply outside the general no-zoning picture124. If you're buying a smaller tract, confirm any prior split from a larger parcel went through the county's plat-approval process, since residential subdivisions of five acres or less require it22. Property taxes run higher here than in many rural Texas counties: an effective rate near 2.1%, with a median bill around $3,490 a year against a typical home value of about $233,320373839.

Watch-outs

  • El Paso County's Permits page says the county can't issue building permits, but a separate 2012 Commissioners Court order still requires registration and mandatory third-party inspections for new single-family homes, duplexes, and large additions in unincorporated areas; don't assume 'no permit' means 'no requirements'30.
  • No official county or state source confirms whether long-term RV occupancy is allowed on private unincorporated land; the only published RV rule covers County-owned property, not private lots28.
  • No official source establishes a countywide private-well permit requirement or an agricultural exemption from county development rules; confirm both directly with Planning and Development before you rely on either25.

Water rights & wells in El Paso County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Texas’s water agency.

Actively managed

This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.

Household wellExempt up to a limit

Texas groundwater is governed by the rule of capture; a Groundwater Conservation District must exempt qualifying domestic/livestock wells and may not restrict their production, but well registration and spacing rules can still apply and the exemption does not cover wells serving a platted subdivision.

Limit: Domestic/livestock well exempt from GCD production permitting if on a tract >10 acres AND incapable of producing >25,000 gal/day (Tex. Water Code §36.117)
