Codes & Texas state rules

  • Texas cities apply the International Residential Code for homes (Local Government Code ch. 214) and generally adopt ICC codes plus local amendments — check which edition Liberty Hill uses.
  • Cities may not regulate exterior building materials beyond national codes for most residential and commercial buildings (HB 2439, 2019).
  • Septic (on-site sewage) systems fall under TCEQ rules, often administered by Williamson County where city sewer is unavailable.
  • Properties in a FEMA flood zone need a floodplain development permit from the local floodplain administrator.
  • Homeowners may often pull permits for work on their own homestead; trades work for hire requires a state license.
