Rent & eviction protection

Is 619 17Th Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1926

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1926
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 619 17th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1926 and currently owned by the Yoshi Serizawa Revocable Trust, this flats and duplex-style building has undergone several significant maintenance and improvement projects over the past two decades. Most notably, in late 2021, the building underwent kitchen and bathroom remodeling work valued at $28,000, which included electrical and plumbing updates. A concerning incident occurred in March 2022 when a tenant reported mold issues and leaks, with the situation compounding due to improper remediation attempts involving bleach treatment and paint over application. This led to the issuance of multiple building violations related to ventilation and lead hazard concerns, though these were officially abated by April 2022.

The building's maintenance history includes some important infrastructure work, such as a sewer replacement project completed in 2009 that involved approximately 27 feet of piping from the foundation to the city connection. More recently, in January 2024, there was a permit for furnace installation, though this permit has since expired. The property has experienced multiple parking-related issues in the surrounding area between 2022 and 2023, with several documented instances of vehicles blocking driveways, though these are external to the building itself. A complaint regarding unauthorized demolition work and construction debris blocking the sidewalk was filed in November 2021, which was resolved by January 2022. While the building has undergone various improvements, the past issues with mold, lead hazards, and ventilation suggest historical maintenance challenges that were addressed through subsequent renovations and repairs.

Risk rating

How 619 17Th Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
