Rent & eviction protection

Is 52 Beaver St 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.

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 1932
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 residential building at 52 Beaver Street in San Francisco's Duboce Triangle neighborhood is a two-story flats and duplex structure built in 1932 and currently owned by the Low-Aoki Family Revocable Trust. The property underwent significant renovations in 2013, including a comprehensive $70,000 project that modernized the kitchen and bathroom facilities, added a new bathroom, and upgraded associated electrical and plumbing systems, with the work being completed under proper permits for both plumbing and electrical work. This renovation included converting galvanized water lines to copper and upgrading the electrical service to 200 amps with new fixtures and safety features.

The building has maintained its structural integrity through various improvements over the years, including earlier renovations in 2001 that involved demo work on kitchen and bathroom facilities and structural modifications. However, the property has experienced numerous parking enforcement issues in the immediate vicinity throughout 2024, with ten reported incidents of driveway blocking or illegal parking between February and October 2024. While most of these cases resulted in citations or attempts at enforcement, several were documented as "unable to locate" or "could not be validated" upon officer response, suggesting potential ongoing challenges with parking management in the area, though these incidents are external to the building itself and primarily affect public street access.

Risk rating

How 52 Beaver St'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
68thpercentile

Out of 287 buildings in this neighborhood, 92 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
