Building permits, zoning and septic rules in Troy, Alabama

Building a new home, addition or accessory structure inside Troy, Alabama city limits requires a city building permit, with plans and a site plan showing setbacks1. Troy runs its own zoning and subdivision rules through the City Planning & Community Development Department23. Septic permits come from the Pike County Health Department, but new construction must connect to city sewer when a main is within 500 feet45.

Do you need a building permit in Troy, Alabama?

Yes. New homes, additions and accessory structures inside Troy city limits need a building permit, and new-home plans must be approved along with a site plan showing the required setbacks1. A mobile home placed outside a mobile-home park also needs Board of Adjustment approval before the permit is issued12. The Inspection Department enforces the 2021 International Building Code and International Residential Code and the 2020 National Electrical Code13. The State Building Code run by the Division of Construction Management does not generally govern ordinary residential property, so the city is the code authority for a house here14.

Alabama exempts an owner who acts as their own contractor on a one-family or two-family home from the residential home-builder license, with conditions: the owner supervises personally, the home is for their own use and not for sale, and subcontractors over $10,000 must be licensed15. That is a licensing exemption; we could not confirm any exemption from Troy's own building permits, so ask the Inspection Department16.

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

The City of Troy Inspection Department enforces the building codes inside city limits and is at 301 Charles W. Meeks Ave.; its phone is (334) 566-017716. New-home permit fees are 0.0025 of the estimated contract amount plus $5.00, and plan review is generally 7 days67. Construction projects require foundation, rough-in and final inspections8. Inside Troy, the city and not Pike County issues building permits; septic permits stay with the county health department17.

Does Troy have zoning, and what does it mean for lot size and homes?

Troy has a zoning ordinance, most recently amended on May 28, 2024, and an Official Zoning Map9. Rules differ by district. In the RR (Reserved Residential) district, the minimum lot area is 15,000 square feet, and Pike County Board of Health minimums prevail where sewer is unavailable and a larger area is needed for percolation10. RV parks are allowed in RR only on appeal18. Cottage Housing Developments allow one-story units of 800 to 1,000 square feet and two-story units of 1,200 to 1,400 square feet19. Dividing land inside Troy falls under the city planning department's subdivision regulations3. We could not confirm district setbacks, tiny-home rules, accessory dwelling units or temporary camping rules; ask the Zoning Office16.

How do sewer and septic permits work in Troy?

New construction in Troy must connect to the city sanitary sewer when a city main is within 500 feet of the closest property line5. The city can exempt a property when service is unavailable, when connection is infeasible, or when an easement cannot be obtained after a good-faith effort5. Where sewer is not required, the Alabama Department of Public Health program runs through the county health department: an application for a Permit to Install goes to the Pike County Health Department, and construction may begin only after the permit is issued411. The installer must be licensed by the Alabama Onsite Wastewater Board4. Roughly 42% of Pike County soils are not limited for a conventional drain field, so expect a soil evaluation and possibly an engineered design2021. Call Environmental Services at 334-566-286022.

What about floodplains, stormwater and driveways in Troy?

Development in special flood hazard areas and flood-prone areas that Troy regulates must follow the city's floodplain standards, and required approvals from other agencies go in the floodplain development permit file23. A site that disturbs one or more acres, or is part of a larger plan that will, needs state construction stormwater coverage, with an application fee of $1,38524. For commercial and industrial development, Troy allows at most 2 access points per public street, at least 75 feet apart25. We could not confirm a residential driveway permit rule; ask the Inspection Department16.

Building a home in Troy: the steps, in order

  1. Check the lot's zoning district on the Official Zoning Map9.
  2. Find out whether a city sewer main is within 500 feet; if not, apply for a Permit to Install with Pike County Environmental Services522.
  3. Submit printed and digital plans and a site plan showing setbacks to the Inspection Department716.
  4. Build to the adopted codes and call for foundation, rough-in and final inspections8.
  5. Where building and trade permits apply, final approved inspections come before a certificate of occupancy26.

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

Inside Troy, the city sets zoning and issues building permits, while septic permits come from the Pike County Health Department17. Pike County has no countywide zoning for unincorporated land, and its subdivision rules cover only unincorporated areas, so neither applies to a lot inside Troy2728. For land outside city limits, see the Pike County page. Before you buy, confirm the zoning district, sewer availability and any floodplain designation. The typical Pike County home value is about $165,42329.

Watch-outs

  • Sewer connection is mandatory for new construction when a city main is within 500 feet of the property line, which can rule out septic5.
  • The owner-builder exemption is from Alabama's home-builder license, not from Troy's building permit; subcontractors over $10,000 must still be licensed15.
  • We could not confirm Troy rules on wells, tiny homes, accessory dwellings or short-term rentals; ask the Inspection Department16.
