If you build or remodel homes in unincorporated Shelby County, Monday morning's county commission meeting is worth your attention. Commissioners have scheduled a public hearing on adopting the 2024 International Residential Code with energy amendments, which would replace the 2015 edition the county enforces today (via Shelby County).
The meeting starts at 8:30 a.m. on Nov. 9 at the Shelby County Administration Building at 200 West College St. in Columbiana. The hearing comes early on the agenda, right after public comment, and it's the only public hearing listed.
The agenda lists three related code items under the commission's Budget, Finance and Legal committee: proposed adoption of the International Energy Conservation Code, the International Building Code and the International Residential Code. Only the residential code is tied to an edition on the agenda itself, and that's the 2024 edition. The agenda doesn't say which editions of the energy and building codes are proposed.
The supporting pages behind those three items run to nearly 50 pages, but they aren't posted with the online agenda. That means the specific local amendments, including what the "energy amendments" change, aren't public online yet. Builders who want to see the details before Monday should ask the county's Development Services office for the packet.
According to the county's adopted codes page, Shelby County currently enforces the 2015 International Residential Code with Appendix G and the 2015 International Energy Code on the residential side (Shelby County Adopted Codes). The commercial side is already newer: the county lists the 2024 International Building Code, along with the 2024 existing building, plumbing, mechanical, fuel gas and fire codes, and the 2026 National Electrical Code.
So the big change here is on houses. Moving the IRC from 2015 to 2024 skips three full code cycles. That's not unusual in Alabama, where the statewide residential baseline set back in 2016 was also the 2015 IRC and the 2015 IECC with state amendments (ADECA; U.S. DOE).
The agenda also lists an IBC adoption item even though the county already shows the 2024 IBC as enforced. It may be a re-adoption or a cleanup to line the codes up together, but the agenda doesn't say.
The timing isn't happening in a vacuum. A 2024 state law moved authority over Alabama's residential building and energy codes to the Home Builders Licensure Board, and it sets Jan. 1, 2027, as the date when home builders must build to either the state residential code or the local jurisdiction's code (Alabama Legislature, HB 198).
The same law says a local residential code already in effect on Jan. 1, 2027, isn't overridden by the state code, while local codes adopted after that date have to meet the state's minimums. State law also says a county's code can't take effect until 120 days after the commission adopts it by resolution, and that county codes apply in unincorporated areas unless a city agrees otherwise (Home Builders Licensure Board). If the commission adopts on Nov. 9, that 120-day clock would put the earliest effective date around early March 2027, unless the county's resolution handles timing differently.
Other items on Monday's agenda include bid awards for traffic signal installation and on-site metered concrete for the Highway Department, plus water meters for Water Services.
Why it matters for Contractors
A three-cycle jump in the residential code touches almost every trade on a house: framing details, energy envelope requirements, mechanical and duct provisions, and inspections. Even with a likely delay before it takes effect, jobs you price this winter could be permitted under the new rules.
For small builders and remodelers working in unincorporated Shelby County, a few practical steps make sense:
Ask for the packet. Development Services can be reached at (205) 620-6650. The local amendments matter as much as the base code, especially on energy.
Show up or speak up. The hearing is the public's chance to comment before the commission votes. If a change would hurt how you build, Monday is the time to say so.
Watch the effective date. Find out exactly when the new code applies and whether permits already in the pipeline stay under the 2015 rules.
Start reading now. If you've been building to 2015 for a decade, it's worth getting your hands on the 2024 IRC and talking with your inspector before the first job lands under it.
