Steps to Building a House in Alabama, from Lot to Move-In
The order matters more than most people expect. Settle the land questions first, then design and money, then permits and building. Here's the sequence, with the Alabama-specific issues in the middle of it.
1. Check the land before you buy it
- Jurisdiction. City or county decides whose permits you need. Oxford: city steps. Elsewhere: county steps.
- Sewer or septic. No sewer means a soil evaluation before you commit; ADPH lists who can do it.[1]
- Flood zone. Check FEMA's map.[2] Homes in a mapped hazard area must be elevated above the base flood elevation.[3]
- Soil. The USDA's free Web Soil Survey maps soil types parcel by parcel, a useful first look before paying for testing.[4]
2. Plan, price and pay
Get plans and a written price, then decide how you'll pay. HomeGuide's Alabama range is $150 to $300 a square foot for builder-grade and $300 to $500 for custom, before land.[5] Our cost page breaks that down; loans covers financing.
3. Permits and approvals
In Oxford you need a building permit before excavating or even storing materials on the lot, and the City's 311 answer puts the wait at about two weeks.[6][7] Add the septic Permit to Install where there's no sewer,[8] a floodplain permit if any of the work is in a mapped hazard area,[3] and a 911 address.[9]
4. Build, with Alabama in mind
Energy code
Alabama's Residential Energy Code is the 2015 IECC with state amendments, enforced from October 1, 2016.[10][11] The state rule covers climate zones 2 and 3 and calls for air-leakage testing with a blower door, with a maximum of 5 air changes per hour.[10] Since October 1, 2024, the Home Builders Licensure Board has held authority to adopt the state's residential building and energy codes.[12]
A storm safe room
A house that isn't built yet is the easiest place to add a safe room. FEMA's P-320 guide covers safe rooms for one- and two-family homes and includes prescriptive design plans that meet FEMA's criteria, built on the ICC 500 storm shelter standard.[13] Ask your builder whether a room in your plan can be built to it.
Inspections and sign-offs
Expect inspections as the work goes, and keep copies. Where there's a septic system, it can't be used until the health department issues its Approval for Use.[8]
5. Move in
HomeGuide puts typical construction time at 6 to 12 months or more.[5] Walk the house with the builder before the last payment and get warranties in writing; the state doesn't require builders to offer one.[14]
Questions to ask a home builder before hiring
- What name and number is your Alabama license under, and when does it expire?[15]
- Can I see proof of liability insurance and workers' comp?[16]
- What's the payment schedule, tied to which stages?[16]
- Which materials, brands and models are included, in writing?[16]
- What warranty do you give, and on what?
- Who is my contact on site, and how do changes get priced?
- Can you build a FEMA-criteria safe room, and what would it add?
- Have you built under the current Alabama energy code, including the blower-door test?
