Murfreesboro's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Murfreesboro, Tennessee, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Building Permits

Decks, fireplaces, and roof overhangs built onto a Murfreesboro home can't sit within 5 feet of a side lot line under the city's amended residential code, with a narrow overhang exception.

Key details: Side setback: 5 feet minimum. Overhang exception: 12 inches with fire rating. Structure spacing: 10 feet between buildings. Code basis: Amended IRC Section R302.1.

Building a deck, patio structure, or addition that violates the 5-foot side-lot-line setback is enforced as a Code violation under Section 7-4, punishable by a fine up to $50.00 per day the violation continues.

Electrical Permits

Altering a home's electrical service, panel, or circuits in Murfreesboro is prohibited without a permit issued to a licensed electrical contractor by the Building and Codes Department.

Key details: Permit holder: Licensed electrical contractor. Adopted code: 2017 National Electrical Code. Issuing office: Building and Codes Dept.. Late-start penalty: Permit fee doubled.

Starting electrical work before the permit issues doubles the required permit fee under Section 11-9(B), on top of any penalty for uninspected wiring.

Plumbing Permits

Murfreesboro requires plumbing work in the City, or work connected to the City water or sewerage systems, to meet the 2024 International Plumbing Code, including Appendix B, as amended in City Code § 23-2. One and two-family dwellings and townhouses up to three stories high follow the International Residential Code instead. The Building and Codes Department is the code agency, and a violation carries a fine of up to $50 per day.

Key details: Adopted code: 2024 International Plumbing Code, including Appendix B. Residential plumbing: International Residential Code for 1-2 family dwellings and townhouses. Code agency: Building and Codes Department. Emergency repairs: Permit due within two working days. Maximum fine: $50.00 per violation, each day separate.

Section 23-4 punishes any violation of the International Plumbing Code, or any failure to comply with it, with a fine not exceeding $50.00. Constructing, installing, altering, replacing, enlarging or repairing a plumbing system in violation of the Code counts. Each violation and each day of the violation is a separate offense, and the fine is on top of recovery of costs, which the violator also owes. Starting work before a permit exposes the applicant to the doubled fee under Section 108.4.

Fire Sprinkler Requirements

Murfreesboro deletes Section R309, the automatic fire sprinkler section of the 2024 International Residential Code, in its entirety under City Code § 7-12(S). The model code's sprinkler section does not apply to homes covered by the residential code. One narrow mandate survives: a medical care facility inside a dwelling unit, where occupants cannot save themselves, must be sprinkled under Section P2904.

Key details: Governing section: Murfreesboro City Code § 7-12(B), (C) and (S). Deleted: Section R309, automatic fire sprinkler systems, deleted in its entirety. Remaining mandate: Medical care facility in a dwelling unit sprinkled per P2904. Code edition: 2024 International Residential Code, adopted in § 7-11. Administered by: Building and Codes Department, Chief Building Official.

The sprinkler amendments carry no separate penalty. Enforcement runs through the permit system. Under § 7-12(L), starting work before the permit issues means paying two times the established permit fee, and the Chief Building Official can waive the doubling only on a showing of good cause. A medical care facility in a dwelling that skips the P2904 sprinkler system fails the R101.2 requirement and cannot pass inspection. Orders can be appealed to the Construction Board within 20 calendar days of service.

If you are coming from a city with tighter rules, you will find Murfreesboro gives residents more flexibility on fire sprinkler requirements.

The Bottom Line

Murfreesboro's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Murfreesboro is broadly strict or permissive.
