What are the Short Term Rental Regulations San Francisco?

At its core, the San Francisco short term rentals law, formally known as the Short-Term Residential Rental Ordinance, is designed around one fundamental principle, which is your rental must be your primary residence. This is not a side gig for investors with multiple properties. It is strictly intended to allow permanent local residents to occasionally rent out their own homes.

Here are the (Short-term Rental) STR laws that you should know:

The Primary Residence Rule: The Anchor of STR Laws

To legally operate, you must prove your rental unit is where you permanently reside. This is the bedrock of all San Francisco short-term rental laws.

  • Permanent Residency Defined: You must occupy the unit for a minimum of 275 nights per calendar year. That’s roughly 75% of the year.
  • Initial Requirement: You must have lived in the unit for at least 60 days before you can even apply for a Short-Term Rental Certificate.
  • One Unit Only: You can only register and rent out the specific unit in which you live, even if you own a multi-unit building.

This is where the law truly restricts full-time apartment conversions.

  • Hosted Rentals (Sharing a Room): If you are present in the unit during your guest’s stay (e.g., renting out a spare bedroom), there is no limit on the number of nights you can host per year.
  • Unhosted Rentals (Renting the Entire Unit): If you rent out your entire unit while you are away, you are limited to a maximum of 90 nights per calendar year. This cap ensures the property remains a home, not a hotel.

Registration with the Office of Short Term Rentals San Francisco

To register, you must provide:

  • Proof of residency
  • Proof you live in the home
  • Proof of insurance

How to be in Compliance with the Airbnb San Francisco Rules

Compliance is a two-part process involving two separate government offices. You need to obtain two different documents, and your failure to do so is the main trigger for the OSTR to issue penalties. Here’s a guide on how to open a short-term residential rental.

Step 1: Get Your Business Registration Certificate

First, because the city considers short-term rental activity a business, you must register with the San Francisco Treasurer & Tax Collector’s Office.

  • Action: Apply for a Business Registration Certificate and obtain a Business Account Number (BAN).
  • Cost: While the certificate itself is free, there is an annual fee you must pay to the Rent Board.
  • Why it Matters: You need this BAN before you can apply for your main short-term rental license.

Step 2: Obtain Your Short-Term Rental Certificate

This is the main license issued by the OSTR.

  • Action: Submit a complete online application to the OSTR.
  • Key Requirements:
    • Proof of Primary Residence: You must provide at least two approved documents (like a valid California Driver’s License or voter registration) showing your address.
    • Business Registration Certificate: Your BAN from Step 1.
    • Liability Insurance: Proof of property liability insurance coverage. Airbnb Management San Francisco offers this coverage, but you should confirm.
    • Application Fee: The non-refundable application fee is substantial (currently $925 for a two-year certificate, as of the latest updates).
  • Ongoing Compliance: Once certified, you must display your OSTR certificate number on all listings (e.g., Airbnb, VRBO, etc.).

Step 3: Collect and Remit San Francisco Tax (TOT)

All rentals for less than 30 days are subject to the city’s Transient Occupancy Tax (TOT).

  • Tax Rate: The TOT rate is 14% of the gross rent.
  • Responsibility: As the host, you are responsible for collecting this tax from the guest and remitting it to the city.
  • Platform Role: Many hosting platforms, including Airbnb, collect and remit the TOT on your behalf. However, you are legally responsible for confirming this is done correctly.

Step 4: Quarterly Reporting

Certified hosts must file quarterly reports with the OSTR detailing their rental activity. This is the city’s way of monitoring the 90-day unhosted cap and ensuring overall compliance.

  • What to Report: Dates rented, whether you were present (hosted or unhosted), the platform used, and the amount paid for each stay.

San Francisco Weekly Rentals & Short Term Housing

For guests looking for San Francisco weekly rentals, the STR rules still apply. Weekly stays fall under short-term rental rules because they are fewer than 30 days.
