Local context for Houston
Houston permits are issued by the Houston Permitting Center through the Houston Permit Portal. Houston Chapter 19 floodplain regulations, updated after Hurricane Harvey, require new construction in the 100-year floodplain to be elevated 24 inches above the 500-year flood elevation (3 feet above for critical facilities), significantly stricter than federal NFIP minimums. Texas does not license general contractors statewide, but TDLR licenses trades.

Does the Houston flood elevation rule really require 2 feet above the 500-year flood?
Yes. Chapter 19, updated after Hurricane Harvey, requires new construction in the 100-year floodplain to sit 24 inches above the 500-year flood elevation. Critical facilities require 36 inches. This is stricter than the federal NFIP standard of 12 inches above 100-year BFE.

Texas does not license residential general contractors statewide. Houston does not require a city GC license either. Plumbing, electrical, HVAC, and related trades require TDLR licensing, and Houston verifies at permit issuance.
