Nashville ADU Zoning & Owner Rules

Housing and Building Standards Tennessee 3 Minutes Read · published February 07, 2026 Flag of Tennessee

In Nashville, Tennessee, accessory dwelling units (ADUs) are regulated by Metro planning and building rules that affect where you can build an ADU, who may occupy it, and what permits are required. This guide summarizes how Nashville treats ADUs, how owner requirements interact with zoning, the permitting path, enforcement and common violations, and practical next steps for homeowners considering an ADU.

Overview

ADU rules are set by Metro Nashville planning and the municipal code; development standards may include lot, size, setback, parking, and owner-occupancy conditions. Before design or construction, confirm your parcel's zoning district and any overlay rules with Metro Planning and consult the official municipal code for enforceable provisions. For planning guidance and the latest rules see the Metro planning ADU resources [1] and the Metro code of ordinances [2].

Check zoning and overlay districts before preparing plans.

Zoning & Owner Requirements

Local zoning sets whether an ADU is allowed and what owner requirements apply. Typical owner-related conditions may require owner occupancy of either the principal dwelling or the lot, limits on short-term rentals, and registration or licensing for rental use. The exact owner-occupancy text, rental restrictions, and unit size limits are published in Metro planning guidance and the municipal code; where the code text is not explicit on a point, the planning page or code annotation is the controlling source [1][2].

  • Confirm allowed zones and overlay requirements with Metro Planning.
  • Determine owner-occupancy or registration requirements before applying for permits.
  • Design to meet building code, setbacks, height, and parking requirements.

Penalties & Enforcement

Enforcement of ADU-related zoning, building, and occupancy rules is carried out by Metro Codes and Metro Planning enforcement channels. Where the municipal code or Metro Planning guidance lists fines or civil penalties those amounts apply; if a fine amount or escalation schedule is not published on the cited Metro pages, the amount is not specified on the cited page. For enforcement contact and complaint submission use Metro Codes or the Planning compliance contacts listed in Resources below.

  • Fines: not specified on the cited planning or code pages where amounts are not listed.
  • Escalation (first/repeat/continuing offences): not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to remove or correct, and referral to court or civil enforcement are possible under Metro authority.
  • Enforcer: Metro Codes and Metro Planning; complaints and inspections are processed by the Codes Enforcement division.
  • Appeals/review: where a code or permit decision is issued, appeal routes and time limits are those specified with the decision or permit; if a specific time limit for appeals is not published on the cited page, it is not specified on the cited page.
Failure to obtain required permits can lead to stop-work orders and possible civil enforcement.

Applications & Forms

Most ADU projects require a building permit and related plan review. Specific application names and fee schedules are posted by Metro Codes or the Permit Center. Where a named ADU registration form or fixed fee is not published on the cited pages, that item is not specified on the cited page. Typical steps and documents include:

  • Building permit application (submit plans and structural details to Metro Codes).
  • Plan review and permit fees as posted by the Permit Center or Codes; consult the official fee schedule.
  • Inspections: footing, framing, mechanical, electrical, plumbing, and final inspection are required as part of the permitting process.
Plan review and inspections must be scheduled through Metro Codes' permitting portal.

  1. Confirm your parcel zoning and ADU eligibility with Metro Planning.
  2. Prepare plans that meet building code, setbacks, and parking requirements.
  3. Apply for a building permit via the Metro Permit Center and submit required documents.
  4. Complete required inspections and obtain final approval/occupancy.
  5. If enforcement or complaints arise, contact Metro Codes or Planning for appeal instructions.
