Sunnyvale STR Approval Requirements

Community Development Director approval is required before a host undertakes or advertises a short-term rental.

  • Use the City short-term-rental application.
  • Provide the property address, host information, and requested acknowledgments.

Chapter 19.76 limits a hosted rental to four overnight adult lodgers per night in a single-family dwelling or dwelling unit.

  • Minor children accompanied by an adult do not count toward the four-adult limit.
  • Do not rent to an unaccompanied person under age 18.
  • The host must remain on-site for the entire stay.
  • Use lawful dwelling occupancy and fire-safety limits when they are more restrictive.
  • Do not treat a platform guest-capacity field as City approval.
Safety and records

Sunnyvale STR Safety and Records

  • Confirm smoke, carbon-monoxide, egress, and occupancy requirements for the specific dwelling.
  • Maintain insurance that covers the proposed hosted-rental activity.
  • Keep approval, advertisement, booking, guest, and tax records organized.
  • Retain lodging-tax records for at least three years.
  • Provide guests with clear parking, refuse, noise, and emergency instructions.
Listing and operations

Sunnyvale Listing and Guest Duties

Every short-term-rental advertisement must include the City-issued approval number, and operation must continue to satisfy the conditions supporting approval.

  • Keep the host on-site throughout each booking.
  • Limit stays and adult lodgers to the approved scope.
  • Maintain the property as the host’s primary residence.
  • Keep approval, booking, tax, and guest records organized.
  • Use a local plan for noise, parking, refuse, and neighbor concerns.
Tax filing

Sunnyvale Transient Occupancy Tax

Sunnyvale’s official short-term-rental page states a 12.5% transient occupancy tax applies. Hosts using platforms other than Airbnb must register, file, and remit as directed by City Finance.

  • Airbnb-only hosts should confirm the City’s current platform-collection guidance.
  • Register directly with Finance for non-Airbnb or direct bookings.
  • Submit required returns by the last day of the month following the reporting period.
  • Retain lodging and tax records for at least three years.
  • Confirm the taxable-rent base and treatment of charges with Finance.
Compliance

Sunnyvale STR Complaints and Enforcement

The City directs short-term-rental complaints to online reporting or Neighborhood Preservation. Approval does not excuse violations involving nuisance, parking, refuse, or public safety.

  • Report suspected unregistered or unhosted operation through MySunnyvale.
  • Call Neighborhood Preservation at 408-730-7610 for code complaints.
  • Use 911 for an emergency and 408-730-7100 for non-emergency public safety.
  • Preserve approval, advertisement, booking, and tax records.
  • Correct violations promptly and confirm any appeal path with the issuing office.
Property review

Sunnyvale Property-Level Underwriting

Model a hosted rental from address-specific evidence rather than market-wide projections. Host-presence rules, room count, taxes, and operating costs can materially change the result.

  • Confirm City jurisdiction, zoning, dwelling legality, and approval in writing.
  • Use the four-adult cap and any stricter building or fire limit.
  • Model only the rooms and dates that can operate lawfully with the host present.
  • Price taxes, insurance, utilities, cleaning, repairs, and management.
  • Stress-test rate, booked nights, and maintenance without assuming appreciation.
Contacts and support

Sunnyvale STR Contacts
