Columbia is the Maury County seat and one of the older towns in Middle Tennessee, with a historic courthouse square, Victorian and early-20th-century neighborhoods close to downtown, and newer subdivisions spreading toward Spring Hill. That mix means two very different kinds of projects: careful repair and restoration on older houses, and the usual finishing and upgrading on newer ones. The city recently changed its building codes, and its historic districts have their own review.
New codes as of January 1, 2026
Columbia's Building Inspections office enforces these editions, adopted by Ordinance 4566 and effective January 1, 2026:
- International Residential Code (2024);
- International Building, Existing Building, Energy Conservation, Fire, Fuel Gas, Mechanical and Plumbing codes (2024);
- ICC A117.1 accessibility standard (2017).
Until December 31, 2025, the city used the 2018 editions. If your plans were drawn in 2025, ask whether they need updating for a permit issued in 2026.
For electrical code questions, the city's codes page sends you to Columbia Power and Water Systems, not the building department. Your electrician will know the process.
What needs a permit (and what doesn't)
Columbia's Development Services FAQ answers several common questions directly:
| Project | Permit? |
|---|---|
| Fence | No permit, but the city's fence requirements still apply |
| Shed or accessory building under 200 sq ft | Small accessory permit |
| Accessory building 200 sq ft or more | Accessory structure building permit |
| Retaining wall supporting over 4 ft of earth | Building permit |
| Building, electrical, plumbing or mechanical work | Check the codes page or call 931-560-1560 |
A permit stays valid as long as work keeps going. It expires if the Building Official determines the work has been suspended, discontinued or abandoned for 180 days in a row. Permit status is shown in the city's Online Permitting System, and you'll get an email when it changes.
Front-yard ditches stay open
Many Columbia streets drain to open roadside ditches. Homeowners often want to pipe them over for a smoother lawn or a wider driveway. The city says it doesn't allow converting ditches to piped conveyances in most situations, because the ditch has to stay open to take water from the yard and road. Day-to-day ditch maintenance is the property owner's job. Repairs needing heavy equipment are typically handled by Public Works. Plan driveways and landscaping around the ditch rather than over it.
Five historic districts
Columbia has five historic districts, each with guidelines administered by the Historic Zoning Commission. The city says the commission reviews any exterior modifications or replacement of components on a structure in a district. That includes windows, doors, siding, porches and roofing, not just additions. For some maintenance work, city staff can review and issue a Certificate of Appropriateness on the commission's behalf, which is faster.
The commission meets the third Wednesday of each month at 4 p.m. at City Hall, and the city publishes design guidelines and an application form. If your house is in a district:
- read the design guidelines for your project type;
- ask staff whether your work qualifies for staff review;
- if not, time your application for the next meeting and expect the building permit to wait for the Certificate.
Older houses and lead paint
As Tennessee's environment department notes, lead-based paint was banned for residential use in 1978, and the U.S. EPA requires contractors doing renovation, repair and painting projects that disturb lead-based paint in homes built before 1978 to be certified and to follow specific work practices. Many of the houses near downtown Columbia are that old. Ask for the firm's certification before any exterior painting, window or siding work. See exterior painting, windows and siding.
Licensing
Maury County hasn't adopted Tennessee's Home Improvement license law, so state licensing for general remodeling starts at $25,000, when a contractor's license is required. Trades are licensed separately. Verify any license on the state's Verify search.
Common projects
Restoration on older houses. Repairing wood windows, porches and siding in kind is often easier to approve in a historic district than replacement. See roofing and siding.
Kitchens and baths. Interior work isn't reviewed by the historic commission, though building permits still apply. See kitchen remodeling and bathroom remodeling.
Additions. Rear additions under the 2024 codes, with historic review if you're in a district. See home additions.
HVAC. Older homes often have undersized ductwork or none at all. Ductless systems can be a fit. See HVAC.
