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.

Fire Sprinkler Requirements

Murfreesboro struck the International Residential Code's automatic fire sprinkler requirement entirely, so new one- and two-family homes in the city aren't required to install residential fire sprinklers.

Key details: IRC section deleted: R313 Automatic fire sprinklers. Effect: No residential sprinkler mandate. Applies to: New 1- and 2-family homes. Code basis: Murfreesboro City Code § 7-12(T).

Not applicable: there is no local sprinkler mandate to violate. Fire code violations unrelated to sprinklers, such as blocked egress or faulty wiring, are still enforced under the adopted International Fire Code.

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

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.

Plumbing Permits

Murfreesboro requires all plumbing work to comply with the 2018 International Plumbing Code, or the International Residential Code for one- and two-family homes, adopted by City Code § 23-1, with permits issued by the Building and Codes Department.

Key details: Adopted code: 2018 International Plumbing Code. Small residential: International Residential Code applies. Issuing dept: Building and Codes Department. Emergency repairs: Permit within 2 business days.

Work performed without a required permit is subject to Code § 1-8 penalties; commencing work before permit issuance can double the standard fee unless the Chief Building Official waives it for good cause shown.

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.

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.
