What building code does San Antonio, TX use?
San Antonio, TX currently enforces the 2024 International Building Code. San Antonio adopts its own code editions. Ordinance 2025-01-30-0075 (effective May 1, 2025) moved San Antonio to the 2024 I-Codes while deliberately retaining the 2021 IECC; the ordinance and the city's engagement page cite the 2023 NEC (matching Texas TDLR's statewide baseline) even though Sec. 10-51 of the codified Chapter 10 PDF still prints '2020 edition' - an internal inconsistency resolved here in favor of the newer ordinance.
