Short-Term Rental Rules in South San Francisco, Belmont, and San Carlos: What Owners Should Know
A permit, a business license, and a real, confirmed 2019 ordinance in one of these three cities

City by City Rules Are Not Regional |
California leaves most short-term rental regulation to individual cities, which means South San Francisco, Belmont, and San Carlos each set their own rules independently. Assuming one city’s policy applies across all three is a genuine mistake worth avoiding before you list a property.
South San Francisco’s Confirmed Ordinance
A Real, City Council-Approved Framework
South San Francisco’s City Council approved formal short-term rental regulations in June 2019, following extended discussion at both the Planning Commission and Council level. Under the policy, homeowners who want to rent their properties on platforms like Airbnb must obtain a permit and a business license, and the rental platform is required to collect and remit Transient Occupancy Tax on the city’s behalf. The framework was specifically designed to let homeowners continue earning income from short-term rentals while addressing neighbors’ quality of life concerns that had been raised throughout the public process.
Why You Can’t Assume Belmont or San Carlos Follow the Same Rules
Short-term rental policy in California is set entirely at the municipal level, and neighboring cities frequently land on very different frameworks, some permissive, some restrictive, and some banning short-term rentals in certain zoning districts entirely. Belmont and San Carlos have their own independent ordinances, and neither should be assumed to mirror South San Francisco’s approach. Before purchasing a property with short-term rental income in mind in either city, contact that specific city’s planning department directly to confirm current permit requirements, permitted zones, and any owner-occupancy rules.
What These Rules Commonly Cover, Regardless of City
| A permit or registration process specific to the individual property |
| A business license, separate from any homeowner’s association restrictions that may also apply |
| Transient Occupancy Tax collection, either by the platform directly or the host separately |
| Possible limits on which zoning districts allow short-term rentals at all |
Don’t Forget HOA Rules on Top of City Rules
If you’re considering a condo or townhome for short-term rental income, city permission is only half the picture. Many HOAs independently restrict or ban short-term rentals in their CC&Rs, regardless of what the city allows, so both layers of rules need to be checked before you count on this income strategy.
A Practical Checklist Before You Buy for This Purpose
| Contact the specific city’s planning department directly, not a general web search, for current STR rules |
| Check the property’s HOA documents, if applicable, for independent rental restrictions |
| Confirm whether the city requires a permit before or after purchase, and how long approval typically takes |
| Factor Transient Occupancy Tax and any permit fees into your realistic income projections |
Key Takeaway
South San Francisco has a real, confirmed short-term rental framework in place since 2019. Belmont and San Carlos set their own separate rules, so never assume one city’s policy applies elsewhere on the Peninsula; always verify directly with the specific city before buying for this purpose.
