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 has its own zoning ordinance, last amended in May 20242. Septic permits for every address in Pike County, city or not, come from the Pike County Health Department, but new construction must connect to city sewer when a main is within 500 feet34.

Do you need a building permit in Troy, Alabama?

Yes. New homes, additions and accessory structures inside Troy city limits need a permit, and new-home plans must be approved along with a site plan showing the required setbacks1. The zoning ordinance exempts only minor work: repairs costing $500 or less, painting and flooring1. A Board of Adjustment special exception or variance can support a permit for something that does not otherwise conform to zoning1. Troy enforces the 2021 editions of the International Building Code and International Residential Code, along with the 2020 National Electrical Code9. We could not confirm an owner-builder exemption from city permits; ask the Inspection Department10.

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) 566-017710. Plan review for a new home is generally 7 days; commercial new construction needs state-licensed architect or engineer plans and generally 15 to 20 working days5. Construction projects require foundation, rough-in and final inspections, and a request for inspection needs four-hour notice6. Inside Troy, the city and not Pike County issues building permits; septic permits stay with the county health department3.

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 Map held in the Troy Zoning Office7. 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 percolation8. RV parks are allowed in RR only on appeal11. Mobile homes must meet manufacturer-association standards, carry the seal, be tied down and skirted, and must connect to city utilities when water and sewer are within 100 feet of the lot line12. 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 feet13. We could not confirm Troy rules on tiny homes or accessory dwelling units, so ask the Zoning Office10.

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 line4. 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 effort4. Where sewer is not required, a septic permit comes from the Pike County Health Department, and Alabama requires that permit before an onsite system is installed314. Roughly 42% of Pike County soils lack severe limits for a conventional drain field, so a site evaluation is still needed15. Call Environmental Services at 334-566-286016. We could not confirm whether the city adds its own septic permit step.

What about floodplains 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 file17. For commercial and industrial development, Troy allows at most 2 access points per public street, at least 75 feet apart18. We could not confirm a residential driveway permit rule; ask the Inspection Department10.

Building a home in Troy: the steps, in order

  1. Check the lot's zoning district on the Official Zoning Map at the Troy Zoning Office7.
  2. Find out whether a city sewer main is within 500 feet; if not, apply for a septic permit with Pike County Environmental Services416.
  3. Submit printed and digital plans and a site plan showing setbacks to the Inspection Department510.
  4. Build to the adopted codes and call for foundation, rough-in and final inspections6.

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 Department3. Pike County has no countywide zoning ordinance for unincorporated land, so that fact does not apply to a lot inside Troy city limits19. Before you buy, confirm the zoning district, sewer availability and any floodplain designation. The typical Pike County home value is about $165,42320.

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 septic4.
  • We could not confirm Troy rules on owner-builders, wells, tiny homes, accessory dwellings or short-term rentals; ask the Inspection Department10.
