Do you need a building permit in Athens, Texas?

Yes. Athens requires a building permit to build, alter, enlarge or repair any residential or commercial structure inside city limits, and city staff review every application before it is issued110. Construction may not begin before the permit is issued1.

The city has adopted the 2021 International Building Codes and the 2020 National Electric Code, so plans are reviewed against those editions5. Every permit requires a final inspection, and the applicant is responsible for calling the City of Athens for each inspection the adopted code requires6. A certificate of occupancy must be issued before a new or changed building can be used or occupied7.

We could not confirm an owner-builder exemption from city permits. The state's licensing exemption for electrical work on a home you own and live in is not an exemption from locally administered permits or inspections11.

Who issues building permits in Athens, and how do you reach them?

The City of Athens issues its own building permits through its Development Services staff, at 508 East Tyler Street, phone 903-675-513110. Applications can be emailed to the planning department at planning@athenstx.gov, and a permit is not complete until every required submittal is received12. The city posts a fee schedule on its Forms & Fees page, and the most recent one took effect October 1, 202513.

Inside Athens, the county planning counter is not the place to start. Henderson County's own development office handles floodplain administration only in areas outside any city limits14.

Does Athens have zoning, and what does it mean for lot size, RVs and tiny homes?

Yes. Every property inside Athens city limits has a zoning designation, and the city has 17 zoning districts, each with its own allowable uses, spatial regulations and development standards4215. Check the district for the exact parcel on the city's zoning map before you buy.

Minimum lot sizes depend on the district. The city's single-family districts are SF-15 (15,000 square feet), SF-10 (10,000 square feet), SF-7 (7,000 square feet) and SF-5 (5,000 square feet)16. Dwelling floor area, setbacks, lot coverage and building height are also set district by district, so ask the city for the district schedule171819.

We could not confirm what Athens allows for RV living, tiny homes, accessory dwellings or manufactured homes on a given lot. Ask the city's Planning & Zoning staff at 903-675-5131 which district the parcel is in and whether that use is permitted there15.

How do septic permits work inside Athens, Texas?

We could not confirm who issues septic permits for lots inside Athens city limits. Henderson County Septic Services acts as the county's permitting agent for on-site sewage facilities3, and Texas requires a permit and approved plan to construct, alter, repair, extend and operate a septic system20. Call Henderson County Septic Services at 903-257-9057 to confirm whether a city address falls under its program, and ask the city whether public sewer is available to the lot21.

A lot with city sewer access may not need a septic system at all, but we could not confirm the city's connection rules. If you plan a septic system on a tract of 10 acres or more, Texas has a limited exemption that requires a licensed site evaluation and every other state condition to be met22.

Building a home in Athens: the steps, in order

  1. Ask Planning & Zoning at 903-675-5131 which of the city's 17 zoning districts the parcel is in and what that district allows215.
  2. Confirm water and sewer service with the city, and septic authority with Henderson County Septic Services if sewer is not available21.
  3. Prepare plans to the 2021 International Building Codes and 2020 National Electric Code5.
  4. Submit the building permit application and required submittals to Development Services, including by email at planning@athenstx.gov12.
  5. Wait for permit issuance before any work starts1.
  6. Call the city for each required inspection, and pass the final inspection6.
  7. Get the certificate of occupancy before anyone moves in7.

What stays with Henderson County, and what to check before you buy in Athens

The city's rules stop at the city limits. Unincorporated Henderson County has no county zoning ordinance8, and the county requires a development permit only for development in a designated floodplain area outside city limits9. If the land you are eyeing is outside Athens, read the Henderson County page instead.

Wells in Henderson County fall under the Neches and Trinity Valleys Groundwater Conservation District, which exempts qualifying domestic and agricultural wells from permits but requires them to be registered23. We could not confirm private-well rules inside city limits. A driveway onto a state highway needs a TxDOT permit on Form 105824.

Countywide figures for context: Henderson County's median property tax bill is $1,859 a year25, and its typical home value is $273,12026.

Watch-outs

  • Zoning district decides what you can put on an Athens lot, so get the district from the city before you sign a contract4.
  • We could not confirm who issues septic permits inside Athens city limits; call Henderson County Septic Services at 903-257-9057 before you plan a septic system21.
  • We could not confirm Athens rules for RVs, tiny homes, accessory dwellings or manufactured homes; ask Planning & Zoning at 903-675-513115.
  • City fee schedules change; the posted Athens schedule took effect October 1, 2025, so confirm current fees with Development Services13.
