ARTICLE I · COUNTY BASELINE

CODES & LOCAL AUTHORITY

FIPS 48201

Article I · County Baseline

The county inherits from the state. And adds local rules.

Harris County and the City of Houston generally utilize the 2021 International Building Code family with specific local amendments.

Harris County only exercises permitting authority in unincorporated areas, while the vast majority of the population resides in incorporated cities that manage their own building codes and zoning. Development in unincorporated areas is subject to Harris County Engineering Department regulations, including specific drainage and floodplain management requirements due to the county's flat topography and flood risk.

Harris County enforces strict drainage and detention requirements for all new development in unincorporated areas to mitigate regional flooding risks.

How this fits with the state

The state authority here is Texas Department of Licensing and Regulation; Texas State Board of Plumbing Examiners. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
