Because Nashville and Davidson County merged into a single consolidated city-county government in 1963 (see our property tax guide for the Urban Services District / General Services District split that merger created), zoning across all of Davidson County — Downtown Nashville, The Gulch, and every neighborhood in between — is administered by one body: the Metro Nashville-Davidson County Planning Department, working from the NashvilleNext general plan and Metro's zoning code, with rezoning and variance decisions going through the Metro Planning Commission and, for legislative rezonings, the Metro Council. This is a genuinely simpler picture than a typical multi-city metro, where every incorporated city runs its own separate planning department — here, one planning department covers the entire consolidated county, including the six smaller "satellite cities" inside Davidson County that kept their own municipal governments after the 1963 merger (Belle Meade, Berry Hill, Forest Hills, Goodlettsville, Oak Hill, and Ridgetop), several of which layer their own additional zoning review on top of Metro's base code for parcels within their boundaries.
We were not able to confirm, as of this writing, whether Metro Nashville has adopted anything resembling Charlotte's 2023 Unified Development Ordinance — the sweeping citywide elimination of single-family-only zoning covered in our Charlotte governance guide. Nashville has been the subject of ongoing citywide housing and zoning policy debate in recent years, but we're not asserting a specific outcome here; confirm the current state of Metro's zoning code and any recent amendments directly with the Planning Department before relying on a specific parcel's by-right density.
Franklin, Brentwood, Murfreesboro, Hendersonville, Mt. Juliet, Gallatin, and Smyrna sit in four separate, non-consolidated counties (Williamson, Rutherford, Sumner, and Wilson) and are not part of Metro Nashville's consolidated government or its planning department. Each is an ordinary independent Tennessee municipality that zones under its own city planning and codes department, with rezoning decisions made by its own planning commission and board of aldermen or city commission following the standard public-hearing process. Unincorporated areas of those four counties are zoned separately by each county's own planning office.
Tennessee does not have as comprehensive, centralized a statutory HOA framework as some neighboring states — there's no single, heavily detailed "Planned Community Act" of the kind North Carolina uses for its HOAs. Condo associations are governed by Tennessee's Horizontal Property Act, and Tennessee's Nonprofit Corporation Act generally governs HOAs organized as nonprofit corporations, but the day-to-day authority over assessments, architectural review, and enforcement for a typical single-family-home HOA in this metro is driven mainly by that specific community's own recorded declaration of covenants, conditions & restrictions (CC&Rs) and bylaws, rather than a single detailed statewide statute the way North Carolina's Planned Community Act works. We were not able to independently confirm the full current landscape of Tennessee HOA-specific statutory protections (disclosure requirements, lien/foreclosure procedure, dispute-resolution channels) as of this writing — treat this section as a general orientation, not a complete legal picture, and review a specific community's actual recorded covenants (available from the county register of deeds) before buying into an HOA-governed property, ideally with a Tennessee real estate attorney.
Davidson County has a number of well-established historic neighborhoods with local, binding design-review overlays administered by the Metro Historic Zoning Commission — long-time examples include Edgefield, Lockeland Springs, Germantown, and Waverly-Belmont, among others. None of these fall within our two Davidson County guide areas (Downtown Nashville and The Gulch), which are both largely commercial and high-rise districts rather than historic residential ones; see Section 5 for what does and doesn't apply to each guide city specifically. Outside Davidson County, several of the historic downtown cores in this metro — most notably Franklin's — carry their own binding local historic-zoning overlays, separate from and stricter than honorific National Register of Historic Places listing.
"Local historic review" below means a binding design-review process actually applies to exterior changes, not just National Register listing. Where we could not independently confirm a city's local historic-district ordinance status, we've flagged it as unconfirmed rather than guessing — this is exactly the kind of small-city detail that's easy to get wrong, and worth a direct check with the relevant planning department before you rely on it.
| Guide city | Local historic review? | HOA / governance character |
|---|---|---|
| Downtown Nashville | No — a commercial/entertainment core, not a Metro Historic Zoning Commission overlay district | Condo/high-rise association governance, not traditional single-family HOA |
| The Gulch | No — governed instead by its own Business Improvement District (BID) and LEED-ND neighborhood-development standards, not a historic overlay | Condo/high-rise association governance dominant |
| Franklin | Yes — downtown Franklin's historic core has a local Historic Zoning Overlay with design-review authority, on top of its National Register listing | Mixed — historic downtown largely non-HOA, Cool Springs-area and newer subdivisions heavily HOA-governed |
| Brentwood | Unconfirmed — no citywide historic-district design-review program was independently confirmed this session | Heavily HOA-governed — the dominant pattern across Brentwood's upscale subdivisions |
| Murfreesboro | Unconfirmed — the area around the historic Rutherford County Courthouse square is National Register-listed; whether Murfreesboro separately administers binding local design review was not independently confirmed | Mixed — in-town historic streets largely non-HOA, newer subdivisions and MTSU-area developments HOA-governed |
| Hendersonville | Unconfirmed — no citywide historic-district design-review program was independently confirmed this session | Mixed — older lakefront streets largely non-HOA, newer subdivisions HOA-governed |
| Mt. Juliet | No local historic-district program confirmed — a fast-growing suburb without a historic downtown core of comparable scale to its neighbors | Heavily HOA-governed — the default across the city's recent-decades subdivisions |
| Gallatin | Partially confirmed — downtown Gallatin's historic core (including the restored 1913 Palace Theater) is a recognized historic area, though the specific binding local design-review mechanism was not fully confirmed this session | Mixed — historic downtown largely non-HOA, newer subdivisions HOA-governed |
| Smyrna | No local historic-district design-review program confirmed; the Sam Davis Home is a standalone state historic site, not a neighborhood overlay | Mixed — older in-town streets largely non-HOA, newer subdivisions near the Nissan plant corridor HOA-governed |
Sources: Metro Nashville-Davidson County Planning Department and Metro Historic Zoning Commission materials (Sections 1 and 4, confirmed directly); National Register of Historic Places listings for each city, cross-checked September 2026. Every "unconfirmed" entry above reflects a genuine gap in our sourcing, not a settled "no" — confirm directly with the relevant city's planning or codes department before relying on it.
The consolidated-government structure in Section 1 and the four-county satellite-city picture in Section 2 are both well-documented and don't change often. Tennessee's HOA statutory landscape in Section 3 is an area we've deliberately flagged as only partially confirmed — we plan to research it in more depth in a future update rather than overstate our confidence here. The city-by-city table in Section 5 reflects what we could and couldn't confirm as of September 2026. If you spot something on this page that's changed, or notice a broken link, we'd like to know — see our contact information.
