Summary

Plain-english overview

Stamford does not have a single 'STR license,' but regulates short-term stays through strict zoning and general rental registration laws. In most single-family residential zones (RA-1 to RA-3), the owner must reside on-site during the rental, effectively banning unhosted whole-home rentals in those areas.

What this means for you

To host an Airbnb in Stamford, you first need to check your zoning. If you live in a single-family residential area (like RA-1, RA-2, or RA-3), you can only rent out your home if you stay there at the same time as your guests. You are also required to register your property as a rental with the City and pay for a Certificate of Apartment Occupancy ($75), which involves a safety inspection. Stays under 30 days are subject to a 15% state tax, which Airbnb and Vrbo typically collect for you.
