Montgomery County, Alabama requires a building permit before construction begins on a structure over 200 square feet, but only outside the police jurisdictions of the City of Montgomery and the Town of Pike Road1. Inside those police jurisdictions, the city or town governs building permits and lot size, while septic permits for homes without public sewer still come from the Montgomery County Health Department23. We could not confirm a countywide zoning ordinance4.

Do you need a building permit in Montgomery County, Alabama?

Montgomery County requires a building permit before construction begins on a structure over 200 square feet in county jurisdiction, which is the area outside the police jurisdictions of the City of Montgomery and the Town of Pike Road1. Each police jurisdiction extends 3 miles beyond its city or town limit, so a rural-looking parcel may belong to the city or town process instead; the septic permit stays with the county Health Department either way123. A non-flood-prone building permit costs $100 per structure when construction starts within six months of issuance5. Starting required work without a building permit adds another $100 fee12. Flood-prone projects use a cost-based sliding scale and must follow the county Floodplain Prevention Ordinance effective December 16, 202513. Alabama's owner-builder exemption covers contractor licensing only and does not remove the county building permit requirement10.

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

The Montgomery County Engineering Department handles county building permits for property outside the police jurisdictions of the City of Montgomery and the Town of Pike Road14. Call Building Permits at 334-832-4950 or visit 101 South Lawrence St., Montgomery, AL 3610414. The county's published process requires the permit before work begins, charges a $100 building permit fee for a non-flood-prone structure when work starts within six months, and uses a cost-based fee for flood-prone work15. Ask County Engineering to confirm jurisdiction, flood status, application materials and inspections before finalizing plans; we could not confirm the adopted code edition or a building-inspection schedule.

Does Montgomery County have zoning?

Montgomery County regulates subdivision development in the unincorporated area, but we could not confirm a general countywide zoning ordinance or published county zoning districts16. Alabama counties do not receive broad general zoning authority under statewide law; limited authority can come from local laws or specified circumstances6. A proposed subdivision outside municipal jurisdiction that will use onsite sewage needs a minimum 1-acre lot and at least 100 feet of road frontage11. The County Engineer or designee reviews proposed plats, and an approved plat is filed in the County Probate Office16. Inside a municipal police jurisdiction, lot size for lots under two acres is governed by the City Planning Commission, while outside the police jurisdiction the Health Department governs lot size2. Call the County Engineer at (334) 832-1310 to ask which subdivision, municipal, floodplain or other land-use controls apply to the parcel8.

How do septic permits work in Montgomery County?

Alabama's Soil and Onsite Sewage Branch coordinates the program through county health departments, and the Montgomery County Health Department's Environmental Division reviews local applications and issues permits after state requirements are met173. Call 334-293-6452 or visit 3060 Mobile Highway, Montgomery, Alabama 3610818. A homeowner or business without public sewer must obtain a local health department permit before installing or repairing an onsite system; the application includes the fee, two completed application-and-plot-plan sets, soil results and calculations7. A licensed installer must do the work, the Health Department must be called before installation to schedule inspection, and Approval for Use must be issued before occupancy19. Only about 5.5% of Montgomery County soils are rated without severe limitations for a conventional drain field, so complete the site evaluation before relying on a listing's claim that a lot is buildable20.

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

We could not confirm Montgomery County rules for long-term RV occupancy, temporary camping or tiny-home occupancy on private land in the unincorporated area. Ask the County Engineer at (334) 832-1310 about the parcel and the exact proposed use before buying or moving a unit onto the land8. Alabama recognizes a qualifying manufactured home as a residence when it meets the state definition, bears a HUD Seal and connects to required utilities, but local siting, health, utility and permitting rules still apply21. A manufactured home is not the same category as a travel trailer or motorhome, so the state manufactured-home rule does not answer the RV question21. We also could not confirm a minimum dwelling size or general building setbacks for unincorporated Montgomery County.

Building a home in Montgomery County: the steps, in order

  1. Ask County Engineering whether the parcel is in Montgomery County's permit jurisdiction or within the City of Montgomery or Town of Pike Road police jurisdiction1.
  1. Ask whether subdivision review applies; a septic-served proposed subdivision outside municipal jurisdiction needs at least 1 acre and 100 feet of road frontage11.
  1. If public sewer is unavailable, submit the local septic application and obtain the Permit to Install before installation or repair7.
  1. Confirm flood status, then apply through County Engineering; flood-prone work must follow the county Floodplain Prevention Ordinance and uses a cost-based permit fee22.
  1. An owner may use Alabama's exemption for an owner-occupied one- or two-family home only by personally providing all material supervision and not offering the home for sale23.
  1. For access on a public county road right-of-way, ask Engineering about a turnout; the county provides labor and gravel if the owner supplies the required drainage pipe24.

What should you check before buying land in Montgomery County?

Check jurisdiction first because both named municipal police jurisdictions reach 3 miles beyond their limits1. Verify legal access next: Montgomery County will install a requested turnout on a public county road right-of-way at no charge when the owner supplies the drainage pipe, while access to an Alabama state highway requires an ALDOT permit and is paid for by the applicant2425. Test septic feasibility before closing because only about 5.5% of county soils are rated without severe limitations for a conventional drain field20. Confirm flood classification with County Engineering because flood-prone construction requires certificates, elevation above the base flood level and a cost-based fee13. We could not confirm a permit rule for an ordinary private well, so ask the Montgomery County Health Department about local requirements and testing.

Watch-outs

  • A parcel can look rural while sitting inside a municipal police jurisdiction that extends 3 miles beyond the City of Montgomery or Town of Pike Road limit; confirm which jurisdiction issues the building permit before applying, since the county Health Department still issues the septic permit13.
  • Montgomery County has not confirmed countywide zoning, RV occupancy, tiny-home occupancy, a minimum dwelling size or general setbacks; ask the County Engineer at (334) 832-1310 about the parcel and proposed use8.
  • Only about 5.5% of Montgomery County soils are rated without severe limits for a conventional drain field, so obtain a professional site evaluation before closing20.
