Nashville Metropolitan Planning Commission: Role and Decision-Making

The Nashville Metropolitan Planning Commission (MPC) is the principal land use planning body for Metropolitan Nashville–Davidson County, responsible for shaping how land is developed, subdivided, and regulated across the consolidated city-county jurisdiction. This page covers the Commission's statutory composition, how it evaluates applications, the categories of cases it routinely decides, and the boundaries of its authority relative to other Metro government bodies. Understanding the MPC's role is essential for property owners, developers, and residents who interact with Nashville's zoning and development review processes.

Definition and scope

The Nashville Metropolitan Planning Commission was established under the Metropolitan Government Charter following the 1962 city-county consolidation that created the unified Nashville–Davidson County government (Nashville Metro Charter Government). The Commission operates under Tennessee Code Annotated (TCA) Title 13, which governs municipal and regional planning in the state.

The MPC consists of 15 members: 3 appointed by the Mayor of Nashville, 9 elected from Metro Council districts, and 3 at-large members, as structured under the Metro Charter (Nashville Metro Charter, Metropolitan Code of Laws, §17.04). The Commission is supported by a professional Planning Department staff that conducts technical analysis, prepares staff reports, and manages the Nashville Zoning Code.

Scope of coverage: The MPC's jurisdiction encompasses all of Davidson County, including both the Urban Services District and the General Services District. This consolidated geographic scope distinguishes Nashville's planning authority from peer Tennessee cities, where planning is typically split between a municipality and its surrounding county. Adjacent counties — Williamson, Rutherford, Wilson, Sumner, Cheatham, and Robertson — fall entirely outside MPC jurisdiction and are governed by their own planning commissions or county legislative bodies.

The MPC does not hold authority over:
- Federal properties within Davidson County
- State-owned land subject to Tennessee Department of Transportation decisions
- Private deed restrictions or homeowners association covenants
- Building permit issuance, which falls under Metro's Codes Department (Nashville Building Permits)

How it works

The Commission meets on a published monthly schedule, with agendas posted publicly through the Metro Nashville Planning Department website. Cases proceed through a defined sequence:

  1. Application submission — A property owner or authorized agent files a request (rezoning, subdivision plat, specific plan amendment, or policy amendment) with Planning Department staff.
  2. Staff review — Planners evaluate the application against the NashvilleNext General Plan, the adopted Zoning Code, and any applicable Community Character Manual guidelines.
  3. Staff report publication — A written staff report with a formal recommendation is published prior to the public hearing, typically 5–7 business days in advance.
  4. Public hearing — Affected parties, neighborhood associations, and members of the public may testify before the Commission.
  5. Commission vote — The 15-member body votes on whether to approve, deny, defer, or approve with conditions.
  6. Transmission to Metro Council — For rezonings and certain plan amendments, the MPC recommendation transmits to the Nashville Metro Council, which holds final approval authority over zoning map changes.

The distinction between MPC-final decisions and Council-final decisions is operationally significant. Subdivision plat approvals are generally final at the MPC level, while zoning changes require a second legislative vote by the 40-member Metro Council.

Common scenarios

The MPC regularly processes three primary categories of cases:

Rezonings (Zone Map Amendments): A property owner requests reclassification from one zoning district to another — for example, from RS5 (Single Family) to RM20 (Multi-Family Residential). The Commission evaluates consistency with NashvilleNext and the applicable Community Plan. The Commission's vote is a recommendation; Metro Council enacts the change by ordinance.

Subdivision Plats: Developers seeking to divide land into legally recorded lots submit preliminary and final subdivision plats. The MPC holds final approval authority here, making its decision binding without a Council vote. Plat approval confirms that proposed lots comply with minimum street frontage, lot size, and utility access standards set in the Subdivision Regulations.

Specific Plan (SP) Amendments: Nashville's SP zoning district allows site-specific development standards. Amendments to an existing SP — adding building square footage, modifying setbacks, or changing permitted uses — require MPC review and a Council vote. SP cases constitute a significant share of the Commission's docket in high-growth corridors such as Midtown, The Gulch, and East Nashville.

Decision boundaries

The MPC's authority is bounded by statute and charter in specific ways that are frequently misunderstood.

MPC vs. Board of Zoning Appeals (BZA): The MPC handles legislative land use decisions (rezonings, plan amendments, subdivision plats). The BZA, a separate 5-member body, handles quasi-judicial decisions on variances, special exceptions, and appeals of administrative zoning interpretations. An applicant who cannot meet a dimensional standard — say, a required 20-foot setback — applies to the BZA, not the MPC. These two bodies operate on parallel tracks and do not substitute for each other.

MPC vs. Metro Council: On rezonings, the MPC recommendation carries weight but is not self-executing. Metro Council can override a negative MPC recommendation by a simple majority vote (20 of 40 members). A Council override of a positive MPC recommendation to deny a rezoning does not require a supermajority under standard procedures, though neighbor petition processes can trigger a 27-vote threshold under Metro Code provisions.

Appeals: MPC decisions on subdivision plats and other final actions may be appealed to Davidson County Chancery Court under TCA §27-8-101 (common law writ of certiorari), providing judicial review of whether the Commission acted within its lawful authority.
