Outside city limits, Milam County has no building code or building permit for houses. Rural projects go instead to Planning & Development (254-627-1760) for a development permit, $100 for a residential application, and to the Health Department for a septic permit from $410. Commercial establishments, public buildings and apartment buildings of four or more units need a building permit from the County Fire Marshal under the fire code adopted May 26, 2025. Cameron and Rockdale permit work inside their own limits.

- County road entrance (driveway) permit, approved on site by the precinct commissioner

Inside Rockdale or Cameron, the city’s permit office handles the building permit, not the County.
Send the Development Permit Application with a site plan to Planning & Development; the administrator decides whether the site lies in a flood hazard area and what else is needed.
Have a registered sanitarian, engineer, licensed installer or site evaluator do the soil evaluation and planning materials, then file the septic application in the owner’s name.
Meet the precinct commissioner on site; the commissioner’s office sets the culvert size within 7 days.
Submit plans and fees through MilamCountyPermits.com; the code gives the Fire Marshal 30 days to issue or deny the permit.
Collect the septic License to Operate, and for commercial buildings the Certificate of Occupancy, before use.
Inspections and project closeout
Septic: construction cannot begin until the Health Department issues an Authorization to Construct, which is valid for one year. After the system passes inspection, the owner receives a License to Operate. Owners of aerobic systems must keep a maintenance contract with a state-certified provider on file with the Health Department, and the provider must inspect at least every 4 months; failing either is a Class C misdemeanor with fines of up to $500 a day.

Commercial buildings: the Fire Marshal’s Office schedules its inspections through MilamCountyPermits.com. A failed fire inspection costs $65 to re-inspect, a temporary Certificate of Occupancy is $550 for 90 days, and inspections outside 8:00 a.m.–6:00 p.m. on weekdays need a written request 3 days ahead and cost $150 an hour, with a two-hour minimum.
Texas building code
Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
