Short-Term Rentals in San Ramon, CA

Every city handles short-term rentals a little differently. In San Ramon, California, there are 10 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Host Platform Liability

Short-term rental operators in San Ramon owe Transient Occupancy Tax on every booking, but Municipal Code section D4-27.D.9 credits any TOT a hosting website already collected and paid to the city under its own agreement. Operators pay only the balance, and platforms without such an agreement leave the full obligation on the operator.

Key details: Tax owed: TOT paid annually by Operator. Platform credit: Only if platform has City agreement. Registration: Mandatory for TOT collection. No agreement: Full TOT still owed by Operator. Enforcement: Title B of Municipal Code.

An operator who under-reports TOT by wrongly assuming a platform's collection satisfies the full obligation is liable for the shortfall to the Finance Department. Enforcement follows Title B of the Municipal Code, and unresolved short-term rental violations can trigger the D4-27.G revocation hearing before the Zoning Administrator.

Repeat Violator Strikes

San Ramon can revoke a short-term rental registration for violating its standards or creating a public nuisance, and Municipal Code section D4-27.G bars the property from re-registering for 12 months after revocation. The Zoning Administrator holds a public hearing before any revocation takes effect.

Key details: Revocation process: Requires public hearing. Decision-maker: Zoning Administrator. Re-registration bar: 12 months after revocation. Bar scope: Runs with the property. Daily enforcement: Title B of Municipal Code.

Repeated Terms of Use violations or a nuisance finding can trigger a Zoning Administrator hearing on revocation under D4-27.G. If the registration is revoked, the property cannot hold a new short-term rental registration for 12 months, on top of any Title B penalties already assessed for the underlying violations.

Compared to other cities, San Ramon takes a harder line on repeat violator strikes. The enforcement and penalty structure reflects that.

Host Presence Rule

San Ramon's short-term rental ordinance draws a hard line between hosted rentals, where the owner-operator lives onsite and actively manages the property, and un-hosted rentals, where a local contact stands in instead. Under Section D4-27, un-hosted rentals are capped at 12 weeks a year; hosted rentals face no such annual limit.

Key details: Governing section: Zoning Ordinance Section D4-27.A, D.12. Hosted rentals: No annual rental-frequency limit. Un-hosted rentals: Capped at 12 weeks per year. Local contact: Must respond onsite within 30 minutes. Classification: Declared on annual registration application.

Operating an un-hosted rental beyond the 12-week annual cap, or misclassifying an un-hosted rental as hosted to avoid the cap, is a violation of the registration Terms of Use enforceable under Title B of the Municipal Code. The Zoning Administrator can schedule a public hearing to revoke the short-term rental registration for a Section D4-27 violation or public-nuisance finding, and a revoked registration cannot be reissued at that property for 12 months under Subsection G.

Insurance Requirements

San Ramon requires every short-term rental registration to include proof that the property is insured for short-term rental use before the City will issue a registration under Zoning Ordinance Section D4-27.C.2.i. The requirement sits alongside a mandatory hold-harmless acknowledgment protecting the City from claims tied to the rental's operation.

Key details: Governing section: Zoning Ordinance Section D4-27.C.2.i. Requirement: Proof property is insured for STR use. Paired duty: Hold-harmless/indemnify City, Subsection C.2.j. Effect of missing proof: Application incomplete, registration not issued.

Submitting a registration without proof of insurance leaves the application incomplete under Subsection F, so the City will not issue the registration and the property cannot lawfully operate as a short-term rental in the interim under Section D4-27.C.1. Operating without a completed, insured registration is enforced under Title B of the Municipal Code and can support revocation proceedings before the Zoning Administrator under Subsection G.

Short-Term Rental Parking Rules

San Ramon requires short-term rental guests to park in the property's own garage and driveway before using the street. Municipal Code section D4-27.D.7 bars oversized vehicles and landscape-area parking at any registered short-term rental. The rule attaches to every registration and is checked at annual renewal.

Key details: Onsite requirement: Garage/driveway used first. Street parking: Only after onsite exhausted. Oversized vehicles: Barred entirely on-site. Landscape parking: Prohibited. Enforcement: Title B, revocation possible.

Guests who park oversized vehicles on-site, use landscaped areas, or take street parking before the garage and driveway are full put the registration at risk. Enforcement runs under Title B of the Municipal Code; the Zoning Administrator can call a public hearing on revocation, and a revoked registration cannot be reissued for 12 months under D4-27.G.

Noise Rules

San Ramon holds the owner and operator of a short-term rental jointly responsible for the property's compliance with the City's noise regulations under Zoning Ordinance Section D4-27.D.6. The same Terms of Use ban renting the property for parties, weddings or conferences outright, cutting off the main source of short-term-rental noise complaints before it starts.

Key details: Governing section: Zoning Ordinance Section D4-27.D.6. Liability: Owner and operator jointly responsible. Special events: Weddings, conferences, parties banned, D.2. House rules: Operator must give renters Terms of Use, D.11.

A substantiated noise complaint tied to a short-term rental, or evidence the property was rented for a banned special event under Subsection D.2, is enforceable against the owner and operator jointly under Subsection D.6 and Title B of the Municipal Code. Repeated or serious noise violations can be treated as a public nuisance, letting the Zoning Administrator schedule a hearing under Subsection G to revoke the registration, with a 12-month bar on reissuance at that property afterward.

San Ramon places no calendar limit on hosted short-term rentals under Municipal Code section D4-27.D.12: a homeowner who lives onsite and manages guests can rent rooms year-round. The unlimited schedule applies only while the Operator resides on the property during every stay.

Key details: Annual cap: None for hosted rentals. Condition: Operator must live onsite. Un-hosted rentals: Capped at 12 weeks/year. Registration: Annual renewal still required. Occupancy: 2 adults per bedroom max.

Claiming hosted status while the Operator is absent from the property during rentals reclassifies the stay as un-hosted, exposing the operator to the 12-week annual cap and possible registration revocation under D4-27.G for misrepresenting registration information.

The rules around extended home share in San Ramon lean permissive, but that does not mean anything goes.

Short-Term Rental Permits

It is unlawful to operate a short-term rental anywhere in a San Ramon residential district without first registering it with the City under Zoning Ordinance Section D4-27.C.1. Registration is annual, requires a City-issued registration number on every advertisement, and the Community Development Director can impose extra conditions or send a dispute to the Planning Commission.

Key details: Governing section: Zoning Ordinance Section D4-27.C. Registration cycle: Annual, renewed 30 days before expiration. Unregistered operation: Unlawful under D4-27.C.1. Reviewing official: Community Development Director or designee. Revocation ban: 12 months after revocation, Subsection G.

Operating a short-term rental without registering it, or after a registration has expired, is unlawful under Section D4-27.C.1 and enforceable under Title B of the Municipal Code. A determined violation or public-nuisance finding can trigger a Zoning Administrator hearing to revoke the registration under Section D7-32, and a revoked registration is barred from reissuance at that property for 12 months, per Subsection G.

This is not one of those rules that cities tend to ignore. San Ramon actively enforces its short-term rental permits requirements.

Occupancy Limits

San Ramon caps short-term rental occupancy at two adults per bedroom whenever any part of the dwelling is rented, under Zoning Ordinance Section D4-27.D.1. The bedroom count used for that math is the one the owner reports on the registration application, and it sets the maximum occupancy printed on the proof of registration.

Key details: Governing section: Zoning Ordinance Section D4-27.D.1. Occupancy formula: Two adults per bedroom. Bedroom count source: Reported on annual registration, C.2.e. Applies to: Whole-dwelling and partial-dwelling rentals alike.

Exceeding the two-adults-per-bedroom occupancy cap printed on the registration is a violation of the Section D4-27 Terms of Use, enforceable under Title B of the Municipal Code and treatable as a public-nuisance basis for revocation. Under Subsection G, the Zoning Administrator can hold a hearing to revoke the registration for an occupancy violation, and a revoked registration cannot be reissued at that address for 12 months.

Taxes & Fees

Short-term rental operators in San Ramon must register with the City to collect and remit Transient Occupancy Tax under Zoning Ordinance Section D4-27.D.9, and pay a separate, non-refundable registration or renewal fee under Subsection F set by City Council resolution. Fees paid directly are reduced by any TOT a host website already collects under its own city agreement.

Key details: TOT registration: Required, Subsection D.9. TOT offset: Reduced by platform-collected TOT. Registration/renewal fee: Set by City Council resolution, Subsection F. Renewal deadline: 30 days before expiration. Fee refunds: Non-refundable.

Failing to register for TOT collection or failing to remit the tax due is enforceable under Title B of the Municipal Code and can support a public-nuisance or Section D4-27 violation finding. Letting a registration lapse without paying the renewal fee 30 days before expiration under Subsection F ends the registration, and operating afterward without a current registration is unlawful under Subsection C.1, exposing the property to the same revocation and 12-month reissuance ban under Subsection G.
