Do you need a building permit in Irondale, Alabama?

Yes. Irondale requires a building permit before a new home goes up inside city limits1. The city submission for a new home includes plans, a plot plan, the building permit application, sewer or septic approval, and stair and wall detail1.

Erosion control comes first. Irondale must approve erosion-control measures before it issues a residential building permit, and only erosion-control installation may happen before the permit arrives1. Irondale has adopted building codes by reference through a city ordinance2, and inspections are required during construction5. Before utilities can be turned on, the city needs a certificate of occupancy, which requires a complete subcontractor list with addresses, phone numbers and license numbers10.

Who issues building permits in Irondale, and how do you reach them?

The City of Irondale Inspections Department handles all commercial and residential permitting and inspections inside the city11. Call (205) 769-0692 or visit 1801 Crestwood Boulevard, Irondale, AL 3521011. To get an inspector on site, call for an appointment11.

Irondale publishes a fee schedule. Residential building, electrical, mechanical, plumbing and gas permits carry a $60 issuance fee plus $9.50 per thousand dollars of job cost6. Separate fees apply to demolition, blasting and land disturbance6.

Jefferson County Development Services issues building permits only in unincorporated Jefferson County; for land outside Irondale's limits, see the Jefferson County page.

Does Irondale have zoning, and what does it mean for RVs and lot size?

Irondale has its own zoning. The city's Planning and Zoning Board makes recommendations to the City Council on zoning and approves or disapproves subdivisions and other divisions of property3. Zoning is district-based: in the A-1 Agriculture district, buildings are limited to 2½ stories or 35 feet12, and newly recorded A-1 subdivision lots must be three acres or more3.

For RVs, Irondale's ordinance allows recreational vehicles only in an RVP recreational vehicle park, with a maximum stay of 90 days in a 12-month period; moving to another space in the same park does not reset the clock7. The RVP designation is for recreational vehicles only, and manufactured homes are not permitted there13. We could not confirm a rule for tiny homes or accessory dwelling units inside Irondale, so ask the Inspections Department before you plan one.

How do septic permits work inside Irondale?

Septic permits for land inside Irondale come from the local county health department, which here is the Jefferson County Department of Health4. Alabama requires a septic permit for homes not connected to a public sanitary sewer14.

The process starts with a soil investigation by a local engineer, land surveyor or soil scientist, followed by a permit application and plot plan15. Once the health department issues the permit, the building permit follows15. Irondale's own new-home checklist asks for sewer or septic approval with the building permit application1. Call the Community Environmental Protection Division at 205-930-123015.

For Jefferson County overall, USDA rates 24.1% of soils as not limited for a conventional drain field, a strict rating, so expect a site evaluation and possibly an engineered system16.

Can you live in an RV or tiny home on your land in Irondale?

Not on an ordinary lot, based on what we confirmed. Irondale's RV rule covers RVP recreational vehicle parks, with a 90-day maximum stay in a 12-month period7. The ordinance describes those parks as sites for occupants visiting, vacationing in or passing through the city17. We could not confirm any rule on RV living on a private lot or on tiny homes inside Irondale; call the Inspections Department at (205) 769-0692 before you buy11.

The county's temporary RV-while-building allowance applies only in unincorporated Jefferson County, not inside Irondale; see the Jefferson County page for land outside the city.

Building a home in Irondale: the steps, in order

  1. Confirm zoning and any RV or accessory-building plans with the Inspections Department11.
  2. Get a septic evaluation and permit from the Jefferson County Department of Health if no sewer serves the lot15.
  3. Prepare plans, a plot plan, the building permit application, and stair and wall detail1.
  4. Get erosion-control measures approved; nothing else may be built before the permit1.
  5. Pay city permit fees6.
  6. Schedule inspections by calling the Inspections Department11.
  7. Submit the subcontractor list so the certificate of occupancy can be issued and utilities turned on10.

Alabama's owner-builder exemption to home-builder licensing is available to owners building their own home8; it does not replace the city permit.

What stays with Jefferson County, and what to check before you buy

Septic permits stay with the Jefferson County Department of Health4. We could not confirm a private-well permit rule, a driveway-access rule or an agricultural-building exemption inside Irondale, so ask the Inspections Department about each.

In flood-hazard areas, Irondale requires the lowest floor of new construction to be at least one foot above base flood elevation where that elevation is mapped9. Check the flood map before you buy.

Jefferson County's effective property tax rate is 0.6%, with a median bill of $1,340 a year1819.

Watch-outs

  • Irondale's building codes were adopted by Ordinance 2022-09, but the exact adopted-code text was not located, so ask the Inspections Department which code edition applies2.
  • Unincorporated Jefferson County rules do not apply inside Irondale; use the city's Inspections Department for building permits and the county health department for septic4.
