San Francisco, California Short Term Rental Regulations Guide for Airbnb hosts

Executive Overview: STR Status in San Francisco

Short-term rentals are allowed in San Francisco, CA, but under strict regulatory framework. The city permits short-term residential rentals (stays under 30 nights) only for permanent residents who live in their units as their primary residence. This represents a significant shift from pre-2015 when all short-term rentals were illegal in the city. San Francisco operates under a charter city authority that allows local regulation of short-term rentals while maintaining compliance with state law.

Key Framework: The city operates under the "hosted vs. un-hosted" model where permanent residents can host unlimited stays when present with guests, but are limited to 90 un-hosted nights per calendar year. This regulatory structure balances housing preservation with legitimate home-sharing opportunities.

What do Airbnb hosts actually earn in San Francisco?

Regulatory Changes: San Francisco actively enforces and periodically updates STR regulations; stay current through regular OSTR communication.
Neighborhood Relations: While not regulatory requirements, maintaining positive relationships with neighbors and adherence to noise/parking rules can prevent complaints that trigger enforcement actions.
