Building permits in unincorporated Rutherford County — the fast-growing Middle Tennessee county surrounding Murfreesboro — are issued by the Rutherford County Building Codes Department. The Board of Commissioners adopted the 2024 International Codes effective May 14, 2026.
This Rutherford County building permit guide covers what requires a permit in unincorporated areas, how the Building Codes Department works, fees, state-administered electrical permits, and inspections.
Rutherford County issues permits for unincorporated areas only. The City of Murfreesboro, Town of Smyrna, and City of La Vergne each run their own permitting. Check the county GIS map to confirm your parcel is in the unincorporated area before applying.
What requires a building permit in Rutherford County?
Under the International Codes as adopted by Rutherford County, a permit is required before constructing, enlarging, altering, repairing, moving, demolishing, or changing the occupancy of most structures. Common triggers include:
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Reroofing, windows, doors, and exterior changes
- Electrical, plumbing, mechanical, and gas work
- HVAC installations and changeouts
- Decks, pools, fences, accessory structures
- Change of occupancy or use
- Pre-manufactured home placement
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- One-story detached accessory structure ≤ 200 sq ft
- Replacement of existing fixtures (like-for-like swaps)
- Minor repairs not affecting structural or safety systems
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Rutherford County trade permits
Electrical, plumbing, mechanical, and gas permits are filed separately. Each requires a Tennessee-licensed trade contractor.
Electrical permits
Required for service upgrades, panel work, solar PV, and most wiring — performed by a TN-licensed electrical contractor.
Plumbing permits
Required for new plumbing, repipes, water heaters, and gas piping — performed by a TN-licensed plumber.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and refrigeration — performed by a TN-licensed mechanical contractor.
Miscellaneous & specialty
Reroofs, decks, pools, fences, accessory structures, and demolition are permitted separately.
Verify your contractor's license. Tennessee requires a state contractor license issued by the Tennessee Board for Licensing Contractors (under the Department of Commerce & Insurance / TDCI) for projects valued at $25,000 or more. Separate trade licenses are required for electrical (CE), plumbing, and HVAC/mechanical work. Homeowners may pull their own permit for personal-use construction once every 24 months under TCA § 62-6-103 — but the project must still meet all code and inspection requirements. Verify licensure at tn.gov/commerce/regboards/contractors.
