Rent & eviction protection

Is 460-464 Union 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 1908
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

460-464 Union Street is a 3-story multi-family residential building constructed in 1908, consisting of 6 units and located in San Francisco's Telegraph Hill neighborhood. The property, currently owned by Lou Shuxian & Zhou Yanchun, has undergone several significant renovations and faced multiple regulatory challenges over the past two decades. Most recently, in 2018, there was a kitchen remodeling project costing $20,383, though associated plumbing permits from that period have since expired. The building has experienced several concerning incidents, particularly during unauthorized construction work in 2018 that reportedly caused an accidental fire and involved non-contracted workers, which is currently listed as an active complaint. Additionally, there was a complaint in 2016 regarding unpermitted modifications to a roof access doorway.

The property's maintenance history reveals some serious historical concerns, with violations recorded in 2011 related to interior paint conditions and potential lead paint hazards, though these were subsequently addressed. Earlier routine inspections in 2005 raised issues regarding emergency exits and smoke detectors, which were also resolved. Two alarm system malfunctions were recorded in 2009 and 2008, but no civilian injuries were reported. The building's recent history shows consistent parking enforcement issues, with numerous citations for driveway blocking recorded between 2022 and 2024, though these are not directly related to building conditions. A window replacement permit from 2007 and various citations for parking violations in the surrounding area (totaling around 11 cases in 2022-2024) are also part of the building's permit and complaint history.

Risk rating

How 460-464 Union 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
18thpercentile

Out of 684 buildings in this neighborhood, 561 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
