Short-Term Rental Rules in Middle Tennessee: What to Know Before You Buy

If you're weighing an investment property in Middle Tennessee and the short-term rental (STR) numbers are part of the plan, the single most important thing to understand up front is this: whether you can legally run a property as an Airbnb or Vrbo depends far less on the listing photos than on the address, the zoning, and the local ordinance attached to that specific lot. Two houses on the same street can have completely different rights. A property that someone operated as an STR five years ago may not be re-permittable when it sells. This guide is a plain-English walkthrough of how the rules actually work across Nashville and the surrounding counties — the state law that sets the floor, the city rules that do most of the real work, the taxes, and the non-zoning landmines (HOA covenants, insurance, financing) that catch first-time investors. It is general education, not advice on any single property or a recommendation to buy. STR rules change often, so treat everything here as a framework for the right questions, and verify the current ordinance and your numbers before you write an offer.

First, three definitions that drive every decision

Before any of the rules make sense, you need the vocabulary, because the legal status of a rental in Tennessee turns on how long the guest stays and who owns the property.

• •Short-term rental (the legal trigger): Tennessee law and most local ordinances treat a stay of fewer than 30 continuous days as the short-term threshold. Tennessee's Short-Term Rental Unit Act defines a short-term rental unit as a residential dwelling rented wholly or partially for a fee for a period of less than 30 continuous days (hotels, motels, and bed-and-breakfast establishments are handled separately). The 30-day line is what flips a property from ordinary residential rental into the heavily regulated STR category.
• •Owner-occupied vs. non-owner-occupied: This distinction is the dividing line in many local rule sets. An owner-occupied STR is one where the owner permanently lives at the property (renting a room, a portion, or the whole home while present or away). A non-owner-occupied STR is a pure investment property — the owner lives elsewhere. In several Middle Tennessee jurisdictions, owner-occupied STRs are treated much more permissively than investor-owned ones. If your strategy is to buy and never live there, you are in the more tightly regulated bucket almost everywhere.
• •Mid-term and long-term rental: A stay of 30 days or more generally falls outside the short-term rules entirely. This matters strategically: in places where STRs are restricted or banned, a 30-plus-day model (often called a mid-term rental, popular with traveling nurses, relocating families, and corporate stays) can sometimes be operated where a nightly Airbnb cannot. Always confirm the day-count definition in the specific ordinance — a few jurisdictions phrase it differently.

The state law sets a floor — but cities do the heavy lifting

Tennessee passed the Short-Term Rental Unit Act in 2018 (Tennessee Code Annotated Title 13, Chapter 7, Part 6). It is the backdrop for everything, and it does two big things investors should understand.

First, it limits how far local governments can go. Under the Act, a local government generally cannot enact a brand-new ordinance that outright prohibits short-term rentals as a category, and any health-and-safety regulation it does impose is supposed to use the least restrictive means to achieve the stated purpose. In other words, the state pushed back against blanket bans. But — and this is the part that trips people up — the Act expressly preserves the power of cities and counties to regulate permits, zoning districts, occupancy limits, parking, safety inspections, and nuisances. So a city can lawfully decide that non-owner-occupied STRs are only allowed in certain commercial or mixed-use zones, which functions as a near-ban for investors in residential neighborhoods even though it isn't framed as a categorical prohibition.

Second, the Act created a 'legacy' (grandfathering) protection. A property that was lawfully operating as an STR before a new restriction took effect can generally keep operating under the old rules — but that protection is fragile. Under the statute, legacy status typically ends when the property is sold or transferred, when it goes unused as an STR for a set period (commonly cited as 30 continuous months), or after a defined number of violations of generally applicable local laws. The practical takeaway for a buyer is enormous: a grandfathered STR permit usually does not transfer to you when you purchase the home. If the listing markets 'great existing STR income,' that income stream may legally evaporate at closing unless the property independently qualifies under the current ordinance. Confirm permit transferability in writing before relying on it.

The Act also leaves homeowners associations, condominium associations, and co-ops free to restrict or ban short-term rentals through their own covenants and bylaws, and it lets landlords restrict subletting through leases. The state did not override private contracts — more on that below, because it is one of the most common reasons a 'legal' STR turns out not to be allowed.

Nashville / Davidson County: the most structured — and most restrictive for investors

Metro Nashville runs a formal short-term rental property (STRP) permit system administered by the Metro Codes Department, and it is the single most consequential rule set in the region because so much investor interest concentrates there. Metro uses permit categories that hinge on owner-occupancy.

Owner-occupied permits (Type 1)

An owner-occupied permit requires that the owner be a natural person — not an LLC, corporation, trust, or partnership — who permanently resides at the property, and applicants must document that owner-occupancy. Metro publishes occupancy and per-lot limits (for example, a cap on the number of sleeping rooms rented to a single party and generally one permit per lot in single- and two-family districts). This is the category most accessible to a homeowner who wants to rent a room or rent the whole house while traveling. It is not a path for a pure absentee investor.

Non-owner-occupied permits (Type 2)

This is the investor category — and it is sharply limited. Metro does not permit new non-owner-occupied STRs in its residential zoning districts; they are generally confined to specified commercial, mixed-use, and downtown districts (and even there, often as a conditional use). On top of that, Metro has historically treated many existing non-owner-occupied permits in residential zones as non-transferable when the property sells, which means the right to operate can extinguish at a change of ownership rather than passing to the buyer. The headline for investors: do not assume you can buy a house in a Nashville residential neighborhood and run it as a nightly rental. In most residential zones, that door is closed to new non-owner-occupied operators.

Metro also layers on operational requirements that commonly include annual permit renewal and fees, fire/life-safety standards, proof of liability insurance, and identification of a responsible local contact. These specifics, the eligible zoning districts, the fee schedule, and any caps are set by Metro ordinance and are revised periodically — verify the current rules directly with Metro Codes (nashville.gov) for the exact address you're considering, because the zoning designation of a single parcel can be the entire ballgame.

The surrounding counties vary widely — and that's the opportunity and the trap

Step outside Davidson County and there is no single 'Middle Tennessee' rule. Each city and county sets its own framework, ranging from relatively permissive to effectively closed in residential areas. A few illustrative examples (current as of this writing — all subject to change, so confirm before relying on any of them):

• •Williamson County / Franklin: Franklin regulates short-term vacation rentals through its zoning ordinance and has continued to update those rules. Like the state framework, Franklin's approach preserves legacy status for properties that were legally established and permitted before a new ordinance's effective date — but that protection generally lasts only until the property is sold, transferred, or sits unused as an STR for a set period. New entrants face the current zoning rules, not the old ones. Confirm specifics with the Franklin Planning Department.
• •Rutherford County / Murfreesboro: Historically among the more permissive in the region — Murfreesboro has at times not required a special STR permit for residential operation, while still requiring annual registration of the unit with the county property assessor and collection of the local hotel/occupancy tax. 'No special permit' is not the same as 'no rules,' and local approaches here have been actively debated, so verify the current ordinance.
• •Sumner County (Hendersonville, Gallatin): Hendersonville has historically restricted short-term (under-30-day) rentals to certain commercially zoned areas, meaning a homeowner in a typical residential neighborhood generally could not run a nightly rental, and the city has pursued enforcement (including injunctions) against non-compliant operators. Gallatin operates a short-term rental permit process with fire-marshal inspection at application and renewal and published occupancy limits. Two adjacent Sumner cities, two different rule sets.
• •Wilson County (Lebanon, Mt. Juliet): The county has taken steps to define and address short-term rentals through resolution rather than imposing an outright prohibition, and individual cities set their own rules. As in every county, the city ordinance — not just the county's — governs an in-city address.

The strategic point is not which town is 'best' — rules move, and this article does not make market calls. The point is that in Middle Tennessee, STR-buildability is hyper-local. Underwriting an STR strategy off a regional average, or off what a neighbor was doing two years ago, is how investors end up with a property they legally cannot operate the way they planned. The verification has to happen at the level of the individual parcel, its zoning, and the city's current ordinance — before the offer, not after.

Taxes: three different layers, and who pays what

STR income is taxed in Tennessee through a stack of obligations that surprises out-of-state buyers used to a single 'lodging tax.' The mechanics here are set by the Tennessee Department of Revenue and local governments, and the figures below are general; always confirm current rates and rules with the Department of Revenue and a Tennessee tax professional.

• •State and local sales tax: Tennessee applies its state sales tax (7%) to the rental of short-term accommodations, plus the applicable local option sales tax for the jurisdiction. Because the local rate varies by location, the combined sales-tax rate differs from address to address.
• •Local occupancy (hotel/motel) tax: Cities and counties may levy a local occupancy tax on stays under 30 days — the same kind of tax hotels collect — and the rate is set locally. This is on top of sales tax, not instead of it.
• •Business tax / business license: Tennessee imposes a business tax once a taxpayer's taxable gross receipts in a jurisdiction reach the state threshold (commonly cited at $100,000), which can require registering for and paying business tax and obtaining a business license. Many cities and counties also require their own business license. Thresholds and requirements change — verify with the Department of Revenue.

Who actually remits these matters. Under Tennessee's marketplace rules, when a guest books through a short-term rental marketplace such as Airbnb or Vrbo, the marketplace is generally responsible for collecting and remitting the applicable sales tax and the local occupancy tax to the state on the host's behalf. If you book guests directly (your own website, repeat guests, direct messages), that collection-and-remittance responsibility generally falls back on you. And business-tax obligations and business licensing are not handled by the marketplace — those remain the owner's responsibility regardless of how the booking happens. Registration is typically done through the state's TNTAP portal. The honest summary: the platform handles some of the tax some of the time, and assuming it handles all of it is a frequent and expensive mistake.

Separately, most Tennessee counties also require STR operators to register the unit annually with the county property assessor's office under the state act. That registration is about property classification and is distinct from your tax filings and your operating permit — it's one more box that's easy to miss.

The non-zoning landmines: HOA, insurance, and financing

Even when the city says yes, three private-side issues can still stop an STR cold. These are independent of the local ordinance, and they catch first-time investors constantly.

HOA, condo, and subdivision covenants

Tennessee's state law specifically left associations free to restrict short-term rentals, and many do. A homeowners association, condo association, or recorded subdivision covenant can prohibit rentals under a certain length, cap the number of rental homes, or ban transient occupancy entirely — and a private covenant can be more restrictive than the city ordinance. A property can be perfectly legal to STR under city zoning and still flatly prohibited by its HOA. Before you rely on STR income, read the recorded covenants, conditions, and restrictions (CC&Rs) and any HOA rules for the specific community, and confirm there's no rental restriction. Associations can also adopt or tighten rental rules over time, so an absence of restriction today is not a permanent guarantee.

Insurance

A standard homeowner's policy — and even a standard long-term landlord policy — typically is not built for nightly transient guests and may exclude or limit coverage for STR use, including certain guest-caused damage and liability. STR operators generally need a policy specifically written for short-term rental use (or an appropriate endorsement). Lenders, HOAs, and some city ordinances may also require minimum liability coverage. Talk to an insurance professional about a policy that actually matches the use before guests arrive; discovering a coverage gap after a claim is the worst time to learn this.

Financing and loan occupancy terms

How you finance the purchase can constrain how you're allowed to use it. Owner-occupant loan products carry occupancy requirements, and using a primary-residence loan for a property you intend to run as a full-time investment rental can conflict with the loan terms. Investment-property financing exists, but it generally comes with different down-payment, rate, and reserve requirements, and lenders may have their own views on STR income. Mortgage lenders also typically require insurance and may escrow it. Confirm with your lender that your intended use is consistent with the loan you're getting — before closing, not after.

A practical due-diligence checklist before you buy

If you take one thing from this guide, make it a verification habit. For any specific property you're considering as a short-term rental, work through these questions — ideally during your inspection/due-diligence period, with answers in writing where it counts:

• •What is this exact parcel's zoning district, and does the current local ordinance allow a non-owner-occupied (investor) STR in that district? Verify with the city or county, not the listing.
• •If the listing claims an existing STR permit, is it a non-owner-occupied permit, and does it legally transfer to me at sale — or does it extinguish? Get the answer from the permitting authority in writing.
• •Is there an HOA, condo association, or recorded covenant, and do those documents restrict or prohibit short-term rentals? Read the actual CC&Rs.
• •What are the local occupancy-tax, sales-tax, business-tax/license, and county-assessor registration obligations for this address, and who remits each?
• •Does my financing allow the intended use, and can I obtain insurance written for short-term rental use (and any minimum liability the city/HOA requires)?
• •What is my plan if the rules change — does the property still work as a long-term or 30-plus-day mid-term rental if nightly STR becomes restricted?

That last question is the discipline that separates durable investing from a bet on a single regulatory regime. STR ordinances in Middle Tennessee have changed repeatedly and will keep changing; cities adjust zoning, caps, and enforcement as neighborhoods and politics shift. An investment that only works as a nightly rental is exposed to that risk. An investment that also pencils as a conventional rental gives you a fallback.

The bottom line

Short-term rental rules in Middle Tennessee are a layered system: a state law that prevents flat bans but preserves local control, city and county ordinances that do the real regulating (and vary block by block), a three-part tax stack with split collection responsibilities, and private-side constraints — HOA covenants, insurance, and loan terms — that can override a green light from the city. None of it is insurmountable, and plenty of investors operate compliantly across the region. But the legality and the economics are decided at the level of the specific address, not the metro area, and the rules genuinely change — so nothing here should be read as fixed advice or a recommendation on any property. Verify the current ordinance for the parcel, read the covenants, confirm the tax and registration obligations, and run your numbers conservatively (and ideally have them stand up even under a long-term-rental scenario).
