Short-Term Rentals in Sunnyvale, CA

If you live in Sunnyvale or are thinking about moving there, short-term rentals are one of those things you probably won't think about until they affect you directly. Sunnyvale has 6 specific rules on the books covering different aspects of short-term rentals, and some of them might surprise you.

Short-Term Rental Permits

Sunnyvale bans short-term rentals citywide except for city-approved hosted rentals. Under SMC 19.76.030 and 19.76.050, a host must apply for and receive Community Development Director approval before advertising or operating any stay of thirty days or less, and the director's decision on the application is final.

Key details: Governing chapter: SMC Chapter 19.76. Permit required: Yes, director approval before operating. Application includes: Host and owner contact info, HOA letter if applicable. Decision: Director's approval decision is final. Unpermitted operation: Declared a public nuisance, city attorney abates.

Operating, maintaining, authorizing, aiding, facilitating or advertising a short-term rental without an approved application violates Section 19.76.050(a). Section 19.76.090 declares any short-term rental operated contrary to the chapter a public nuisance that the city attorney may abate, remove or enjoin, in addition to any other remedy available under the code or state law.

This is one of the stricter rules in Sunnyvale's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Host Presence Rule

Sunnyvale only permits hosted short-term rentals, meaning the host must physically reside on site throughout every lodger's stay. Section 19.76.040(a)(4) defines residing on site as using the property as a primary residence for eating, sleeping and daily living while lodgers are present.

Key details: Rule: Host must reside on site throughout the stay. Defined as: Property is host's primary residence. ADU exception: Lodgers in ADU if host is in primary dwelling. Two-family exception: Lodgers in one unit if host is in the other. Enforcement: Director revocation after notice and hearing.

A rental where the host does not reside on site loses the hosted-rental exemption and becomes a prohibited short-term rental under Section 19.76.030. The director may revoke an existing approval for this reason under Section 19.76.070 after mailed notice and a hearing, and Section 19.76.090 authorizes the city attorney to abate the activity as a public nuisance.

Compared to other cities, Sunnyvale takes a harder line on host presence rule. The enforcement and penalty structure reflects that.

Host Platform Liability

Hosting platforms listing Sunnyvale short-term rentals must disclose tax and chapter requirements to hosts, notify hosts of city-reported violations, deactivate listings immediately after a revocation, and retain transaction records for five years under Section 19.76.060.

Key details: Governing section: SMC § 19.76.060. Must disclose: TOT obligations and chapter rules to listers. Must notify host: Immediately after a city violation notice. Must deactivate listing: Immediately after a revocation notice. Records retention: 5 years, produced on lawful request.

A hosting platform that fails to deactivate a listing after a city revocation notice, fails to notify the host of a reported violation, or fails to produce five years of transaction records on lawful request is facilitating a noncompliant short-term rental in violation of Section 19.76.050(a), exposing the listing to nuisance abatement under Section 19.76.090.

Taxes & Fees

Sunnyvale short-term rental hosts collect and remit a 12.5% transient occupancy tax on every stay under SMC 3.16.040(d), register for a TOT certificate under 3.16.070, and pay whatever permit fee the city council sets by resolution under 19.76.080.

Key details: TOT rate: 12.5% of rent, effective January 1, 2019. Registration: TOT certificate required within 30 days. Returns due: Last day of month after each reporting month. Late penalty: 10% plus 10% at 30 days, 25% if fraud. Interest: 1% per month on unpaid tax.

Late TOT remittance draws a ten percent original delinquency penalty, an additional ten percent if unpaid more than thirty days after the due date, a twenty-five percent penalty if the tax administrator finds fraud, and interest of one percent per month on the unpaid tax, all under Section 3.16.090. Every penalty and interest amount becomes part of the tax owed. Operating without the required TOT registration certificate or short-term rental approval is separately enforceable as a public nuisance under Section 19.76.090.

Occupancy Limits

Sunnyvale STR occupancy is capped at 2 guests per bedroom plus 2 additional, not to exceed the building code maximum. Commercial events and parties are prohibited.

Key details: Formula: 2 per bedroom plus 2. 3-Bedroom Cap: 8 overnight guests. Events: Prohibited. Posting: Required on-site. Code: SMC 19.76.

Compared to other cities, Sunnyvale takes a harder line on occupancy limits. The enforcement and penalty structure reflects that.

Key details: Off-Street Spaces: 1 per rented bedroom. RVs and Trailers: Prohibited. Street 72-Hour Rule: SMC 10.12.040. Code: SMC 19.76.
