If you have ever found a great property on Zillow or Redfin, run the numbers, gotten excited — and then discovered the city does not allow short-term rentals there — you know how painful this is. Redfin and Zillow show you price, square footage, and school ratings. They do not tell you whether you are legally allowed to rent the place on Airbnb. That gap has cost investors real money.

Here is how to check STR permit eligibility before you make an offer, city by city.

Why Redfin and Zillow Will Not Help You Here

Zoning and STR permit rules are set at the city or county level, sometimes even at the neighborhood level. They change frequently and vary wildly between markets. No listing platform has the resources or incentive to track all of it, so none of them do. What you need to verify for any property you are serious about:

The Fast Check: What to Look Up First

Before you spend an hour on a city permitting portal, do a 5-minute sanity check. Search: [city name] short-term rental permit requirements 2026. Look for the city's official planning or permitting department page — you want the .gov source, not an aggregator. Those are almost always out of date.

From that page, you are looking for three things: Is a permit required? Is there a cap on permits issued? Is owner-occupancy required? If the city page is confusing or contradictory — which is common — call the planning department directly. Ask: "I am considering purchasing a property at [address]. Would it be eligible for a short-term rental permit?" They are used to this question.

City-Specific Notes for Common Markets

Austin, TX

Austin has three permit types: Type 1 (owner-occupied), Type 2 (non-owner-occupied single-family or duplex), and Type 3 (multifamily). Type 2 is currently being issued but carries more restrictions — notably a 1,000-foot spacing requirement between Type 2 STRs under the same ownership. July 1, 2026 is a hard enforcement deadline: platforms must delist any unlicensed listings within 10 days of city notice. From that same date, licensing shifts to biennial (every 2 years), occupancy is capped at 2 guests per bedroom plus 2 with a maximum of 10, and spacing rules are more strictly enforced. Fines for operating without a license can reach $2,000 per day.

Nashville, TN

One of the most operator-hostile permit systems in the country. Owner-occupancy is required for most permit types. If you list on Airbnb before your permit is approved, you are banned from applying for a full year — not suspended, banned. The city cross-references active listings against its permit database. Check Metro Nashville's permit portal and confirm the exact property address is in an eligible zone before doing anything else.

Denver, CO

Two separate licenses required: a Denver Business License and an STR license. Primary residence only — you cannot STR a property you do not live in. This rules out most pure investment purchases. Confirm with Denver's Excise and Licenses department before buying.

New York City, NY

Local Law 18 effectively bans entire-unit STRs. You must be present during the guest's stay and can host a maximum of 2 guests at a time. Fines run up to $5,000. For most investors, NYC is simply not a viable STR market for whole-unit rentals. Do not buy expecting to rent the full unit short-term.

Portland, OR

Permits are available but there is a 95-night annual cap on total nights rented per year, not per booking. Most hosts do not realize they have hit it until Airbnb flags them. Factor the cap into your revenue projections before buying — it changes the math significantly.

Palm Springs, CA

The contract cap system here is more nuanced than most sources report. In October 2025, the City Council reversed a planned reduction and maintained the higher cap for legacy permits. Current state:

One contract equals one booking regardless of length — a 2-night and a 14-night stay both count as one. One permit per owner maximum. Neighborhoods are subject to a 20% density cap; 10 of 66 neighborhoods are already at or above it, meaning no new full permits are available there at all. Factor all of this into your revenue model before buying.

Houston, TX

Houston's STR ordinance passed April 16, 2025 with enforcement starting January 1, 2026 — but platforms were given until April 1, 2026 to delist non-compliant listings. Registration costs $275 plus a $33.10 admin fee per unit, renewed annually. All applicants must complete human trafficking awareness training. STRs cannot be advertised as event spaces. Fines run $100–$500 per day for operating without registration. Each unit requires its own certificate — one registration does not cover a whole building.

Miami-Dade, FL

Highly fragmented. Rules differ between Miami city, Miami Beach, and unincorporated Miami-Dade County. Miami Beach is extremely restrictive. Always check at the exact municipality level, not the county level. A property listed as "Miami" on Zillow could fall under any of several different regulatory frameworks depending on where the parcel actually sits.

The Deeper Check: Zoning Maps

For properties you are seriously considering, pull the zoning map. Most cities have an online GIS tool where you can enter an address and see the zoning classification. Search: [city] zoning map GIS or [city] parcel viewer.

Once you have the zoning code — something like R-1, R-2, or MU-3 — search for that code in the city's zoning ordinance to confirm STRs are a permitted use. Some zones allow them by right, others require a conditional use permit, and some prohibit them entirely. This takes 20–30 minutes but it is the most reliable check you can do before making an offer.

HOA and Condo Boards: The Wild Card

Even if the city permits STRs, an HOA or condo association can ban them in their governing documents. This is fully enforceable and Airbnb will delist your listing if a verified HOA complaint is filed. Before closing on any property in an HOA or condo building:

HOA bans have blindsided investors who did everything else right. Do not skip this step.

Tracking It All After You Buy

Once you own the property and get permitted, the compliance work does not stop. Most STR permits require annual renewal and the requirements often shift year to year — updated insurance minimums, re-inspections, new local ordinances. Missing a renewal can mean an automatic delisting from Airbnb with no warning.

One property is manageable with a calendar reminder. Multiple properties across different cities with different renewal dates, reporting deadlines, and night cap counters — that gets messy fast. Tools like RentPermit exist specifically for this: permit tracking, renewal countdowns, and cap monitoring across your whole portfolio.

Quick Checklist Before Making an Offer

The research is tedious but takes 2–3 hours per property. That is worth doing before you put down earnest money on something that will not work as an STR.
