Rent & eviction protection

Is 62-64 Williams 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 before 1979
Built 1911

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 1911
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 62-64 Williams Ave in the Bayview neighborhood is a two-unit, two-story multi-family residential building constructed in 1911, currently owned by Tim H S & Ella A Wong Revoc. The building has undergone several significant renovations and faced some maintenance challenges over the years. Most recently, in July 2024, a substantial reroofing project was completed at a cost of $24,500. In September 2023, the property was cited for lead paint hazards, with violations issued regarding peeling and flaking exterior paint, though these were officially abated by December 2023. The building has a history of electrical system updates, including a comprehensive electrical renovation in 2006 that involved replacement of wiring and fixtures in multiple rooms and installation of new circuits and panel. Earlier modifications include a conversion of commercial space to residential use in 1995 and fire repairs in the same year that addressed various structural and safety improvements.

The property has experienced periodic issues with parking violations in the surrounding area, particularly during late 2024 and early 2025, with multiple reports of illegal parking and sidewalk obstruction, though most of these incidents were either unable to be validated or resulted in citations. Two unrelated fire complaints were recorded in April 2009, both of which were promptly corrected. The building's maintenance history shows a pattern of addressing significant structural and safety issues, though the recent lead paint violations underscore the importance of ongoing maintenance and safety compliance.

Risk rating

How 62-64 Williams 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.

Neighborhood percentile
82ndpercentile

Out of 382 buildings in this neighborhood, 69 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
