Summary
Vestavia Hills struck the International Residential Code's automatic fire sprinkler mandate entirely. Local amendments delete both IRC R313.2 and R309.5, so no new one- or two-family home or townhouse built in the city must have a sprinkler system. An NFPA 13D system remains available only as a voluntary alternate to standard garage fire-separation under R302.6.1.
R302.6.1 Alternate provisions. As an alternate to R302.6, the structure shall be protected by an approved NFPA 13d fire sprinkler system. Installation of said system shall be approved by the Fire Marshal. Sprinkler heads shall be installed in the following locations: ... R309.5 Fire Sprinklers. This section shall be deleted in its entirety. ... R313.2 One-and Two-Family Dwellings Automatic Fire Systems. This section shall be deleted in its entirety.

Full Breakdown
Under Code of Ordinances § 5-101(a), the city adopted the 2021 International Residential Code, then amended it in subsection (b). 2 One- and Two-Family Dwellings Automatic Fire Systems, the IRC provision that otherwise requires sprinklers in new detached and townhouse construction, is also deleted in its entirety. 6 dwelling-to-garage fire separation wall. That substitution is optional, not required, and the Fire Marshal must approve the installation before it counts. If a builder chooses the sprinkler alternate, heads are required at fixed locations: two heads in each attached-garage parking space and in the basement, one head over each water heater and furnace area located in a basement or garage, two heads in the kitchen, and one head in each laundry room.
1. These amendments trace to Ord. No. 2329 (3-22-10), most recently updated by Ord. No. 2668 (8-22-16) and Ord. No. 3066 (12-20-21), and are enforced by the city's Department of Building Safety.
Violations & Fines
Because sprinklers are optional, most enforcement here runs through general permit and inspection rules rather than a sprinkler-specific fine. Section 5-3 lets the code official issue a stop-work order on any work done contrary to the adopted code, and continuing work after such an order exposes the violator to penalties prescribed by law. Section 5-51(g) separately fines anyone who starts covered work, including fire-suppression work, before obtaining a permit: a flat $100.00 penalty plus a doubled permit fee, applicable across every division of the Department of Building Safety.
