CODES & LOCAL AUTHORITY
FIPS 48121
Article I · County Baseline

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

2021 International Codes commonly adopted with city amendments.

Denton County permits center on unincorporated work; the cities (Denton, Frisco, Flower Mound, Lewisville, Little Elm, Highland Village) own their permit operations.

Rapid growth corridors (Frisco, Prosper) trigger active review of impact fees and infrastructure requirements.

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.
