STR regulations: what to check before you sign a lease

Short-term rental rules can change from one block to the next. Two units a mile apart can sit in different zones, different cities or different HOAs, and one may be fine to rent by the night while the other is not. A landlord's yes does not settle it, and a listing tool full of nearby Airbnbs proves nothing. Some of those hosts may be operating without a permit.

Do the rules check before you talk money with a landlord. It costs you a few hours. Skipping it can cost you a 12-month lease you cannot use. This guide covers what to check at each level of government and in the building itself, where to find the answers, and what to do when short-term rental is off the table.

A rental arbitrage lease is only worth signing if the property can legally do what your numbers assume. If short-term rental turns out to be banned, capped or only allowed with a permit you cannot get, you still owe the rent. You may also be fined, and your landlord may be fined too, which ends the relationship quickly.

Checking first also helps your pitch. A landlord who hears you name the zoning, the permit process and the HOA rules for their address takes you more seriously than one who hears a revenue projection. Operators who lead with compliance tend to get further than operators who lead with upside.

One rule to keep in mind: the address decides everything. Do not rely on what a city is known for, what a forum post says or what another operator told you. Check the specific property.

Rules can come from several layers at once, and the strictest one wins. Work through each layer for every address.

1. City. Is the property inside city limits? If so, does the city have a short-term rental ordinance? Look for how it defines a short-term rental (usually by number of nights), whether non-owner-occupied rentals are allowed, and which zones allow them.
2. Zoning. Find the property's zoning designation, then check whether short-term rental is permitted, conditional or prohibited in that zone. Some places allow it in commercial or mixed-use zones but not in residential ones.
3. Permit or license. Is a permit, registration or business license required? Is there a cap on the number of permits, a waitlist, a lottery, or a limit per owner or per building? Find out who has to apply: the owner, the operator or both.
4. Primary-residence rules. Some places only allow short-term rental of a host's own home. That rules out standard arbitrage, because you will not live there.
5. Night caps. Is there a yearly limit on rented nights? A cap can break a deal that only works at high occupancy.
6. County. If the property is in an unincorporated area, the county may set the rules instead of a city. Counties can also have their own registration or tax requirements.
7. State. Some states limit what cities can regulate. Others add statewide registration, licensing or tax rules. Check both directions.
8. Operating standards. Look for occupancy limits, parking minimums, noise and quiet-hours rules, trash requirements, safety inspections and a local contact who must respond within a set time.

Write down the answer to each item, the source and the date you checked. Rules change, and you want a record of what was true when you signed.

Most of this is public, but it is spread out. Here is where to look.

• The municipal code. Most cities and counties publish their code online. Search it for terms like short-term rental, transient, vacation rental, lodging and bed and breakfast. Read the definitions section first.
• The zoning map. City or county planning departments usually have an online map. Search the exact address to get its zone.
• The planning or permitting office. Call or email with the address and ask directly: can a non-owner operate a short-term rental here, and what permit is needed? Ask for the answer in writing if you can, and note the name and date.
• The tax authority. The state revenue department and the city or county tax office explain lodging and occupancy tax registration.
• Recent council agendas. Search city council and planning commission agendas for short-term rental items. Pending changes matter as much as current rules. A ban that takes effect six months into your lease is still a ban.

If the code is unclear or the stakes are high, pay a local real estate attorney for an hour. That is cheap next to a year of rent. Market guides give useful background on how to approach specific cities, but always confirm against current official sources for the exact address.

A city can allow short-term rental and the building can still forbid it. HOA and condo rules are private contracts, and they are often stricter than city rules.

• Ask the landlord for the CC&Rs, bylaws and current rules and regulations. Read them yourself.
• Look for minimum lease terms, bans on transient use, limits on the number of rentals in the building, guest registration rules and fines.
• Check whether the board has voted on, or is considering, a change. Ask for recent meeting minutes.
• For apartments, the building's management company may have a policy separate from the owner's wishes.

Then make sure the lease matches. It should say plainly that the landlord consents to short-term or mid-term subletting, that you are allowed to get permits in the property's name if needed, and who pays which fees. A landlord consent clause that is vague is close to having none. Run your draft through the lease clause checker before you sign.

Also check the landlord's mortgage and insurance. Some loans and policies restrict short-term use, and that risk lands on both of you.

Most places tax short stays, often at more than one level. Depending on the location, there may be state, county and city lodging taxes on the same booking.

Booking platforms collect and remit some of these taxes in some places, but not always all of them, and not on direct bookings. Check:

• Which taxes apply to the address, and at which levels.
• Which of those each platform you use collects and remits for you.
• Which you must register for, collect and file yourself.
• How often filings are due, even in months with no bookings.

Put any tax you collect yourself into your underwriting as a pass-through and note the filing work. The hotel occupancy tax glossary entry explains the basics.

Many short-term rental ordinances define a short-term rental by the length of the stay. Stays at or above a set number of nights, often around 30, may fall outside the ordinance and be treated as ordinary residential leases. That is why mid-term rental to traveling nurses, relocating workers and insurance placements can work where nightly rental cannot.

Do not assume the threshold. Confirm the local definition before you rely on it:

• What stay length does the local code use, and is it counted in nights, days or months?
• Does the state use a different threshold for tax purposes than the city uses for zoning?
• Does the HOA set its own minimum lease term that is longer?
• Do mid-term stays need a written lease, and do local tenant protections apply to your guests?

Then rerun the numbers. Mid-term rental usually means lower monthly revenue than a strong STR month but steadier occupancy and lower turnover costs. Our mid-term rentals guide covers how to underwrite it.

Say you find a two-bedroom unit and the rent is $1,800. Here is how the check might go.

1. The zoning map shows a residential zone. The city code allows non-owner-occupied short-term rental there with a permit.
2. The permitting office confirms permits are open, with no waitlist, and the owner must sign the application.
3. No night cap applies. Occupancy is limited by bedroom count.
4. The HOA rules require a minimum stay that is longer than a weekend. That cuts out weekend guests.
5. Taxes: the platform remits some taxes but not one local tax, which you must file monthly.

Result: short-term rental is legal on paper, but the HOA minimum changes the revenue picture. You rerun the deal with longer stays and a mid-term fallback, then decide. If the numbers only work with weekend guests, walk away.

A simple rule: if any layer says no, or the answer is unclear and you cannot get it in writing, do not sign. Listings on ArbiBase come with owner consent and a city, county and HOA rules check already done, which is what our verification covers, but you should still confirm permits and taxes for your own operation.

Before your next landlord call, pick one address and work through every layer: city, zoning, permit, primary-residence rules, night caps, county, state, HOA, lease, taxes and the mid-term threshold. Write down each answer with its source and date. Once the rules hold up, move on to the numbers with our guide to underwriting an arbitrage deal.
