Housing and Building Standards Tennessee 3 Minutes Read ยท published February 21, 2026 Flag of Tennessee

Accessory dwelling units (ADUs) are secondary living spaces on the same lot as a primary dwelling and can expand housing options in Murfreesboro, Tennessee. This guide summarizes how local zoning and building rules typically apply, what permits and inspections you must expect, who enforces the rules, and practical steps to apply, comply, and appeal. It is focused on city processes, building permits, and planning reviews that affect ADU size, location, occupancy, and utilities. Where numerical fines, specific fees, or exact forms are not published on the official code or department pages, the guide notes that the detail is "not specified on the cited page" and points to the official city code and municipal departments for authoritative requirements and forms.

Overview of ADU rules

Murfreesboro regulates accessory structures and accessory residential uses through its municipal code and development regulations. Zoning districts, lot size, setbacks, maximum floor area, and parking requirements can determine whether an ADU is permitted, allowed with a conditional use permit, or prohibited. For the controlling municipal code and zoning text, consult the City of Murfreesboro Code of Ordinances.[1]

Site, design, and zoning considerations

  • Zoning district allowances and conditional uses determine ADU eligibility.
  • Setbacks, lot coverage, and lot size minimums may apply and affect placement.
  • Design standards can include separate entrances, maximum unit size, and required parking.
  • Utility connections and address assignment commonly require coordination with building inspections and utilities.
Check both zoning and building rules early in project planning.

Penalties & Enforcement

Enforcement of ADU-related violations in Murfreesboro is handled through the city's municipal code enforcement and building inspection processes. Typical enforcement actions can include stop-work orders, permit denial, orders to remove or vacate an unlawful unit, and monetary fines where the code authorizes them. If a specific penalty amount or schedule is not published on the cited official pages, this guide notes that it is "not specified on the cited page" and directs readers to the municipal code and enforcing departments for details.[1]

  • Fine amounts: not specified on the cited page; consult the city code or enforcement notices for exact figures.
  • Escalation: whether first offence, repeat, or continuing daily fines apply is not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to vacate or remove an unlawful ADU, and court-ordered compliance are used where authorized.
  • Enforcers: Planning and Zoning, Building Inspections, and Code Enforcement divisions administer reviews and field inspections; contact those offices for complaints and inspections.
  • Appeal/review routes: specific appeal bodies or time limits are not specified on the cited page; check the municipal code and department pages for appeal deadlines and procedures.
If you receive an enforcement notice, act promptly and document communications.

  2. Prepare plans: engage a designer or architect to draw site and building plans meeting setback, size, and code requirements.
  3. Apply for permits: submit building and any required land-use applications to Planning and Building Inspections and pay applicable fees.
  4. Inspections and occupancy: schedule inspections as required and obtain certificate of occupancy before renting or using the ADU.
  5. Appeals and variances: if denied, follow the municipal appeal or variance process set out in the municipal code.
Obtain approvals before leasing an ADU to avoid enforcement actions.
