Rent & eviction protection

Is 475 33Rd 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 1924

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.

Built 1924
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 two-unit, two-story residential building at 475 33rd Avenue in the Outer Richmond, owned by Siu Chun Lee Revocable Trust 2009, has maintained its character as a 1924 flats and duplex structure. The property's documented history reveals several maintenance and infrastructure issues over the years, with the most recent significant incident being a sewage backup in September 2022 that required PUC Sewer Operations intervention and was subsequently resolved. A more serious maintenance complaint was filed in September 2005 regarding the kitchen and bathroom conditions, specifically mentioning loose floor tiles and mold in the bathroom ceiling, though this issue was marked as abated by June 2006.

The building's permit records show minimal activity, with only one street space-related permit issued in October 2012 at an almost negligible cost of $1.00. More recent street-level maintenance issues have been addressed through standard municipal channels, including the pickup of abandoned Christmas trees in February 2023, general cleaning needs in May 2021, and the resolution of illegal postings in November 2013, though these exterior matters are not directly related to the building's residential conditions. The only recorded fire-related incident was a false alarm or call, with no civilian injuries reported and no specific date documented in the provided data.

Risk rating

How 475 33Rd 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
54thpercentile

Out of 1040 buildings in this neighborhood, 478 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
