Rent & eviction protection

Is 478-480 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 before 1979
Built 1925
2 or more units

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 1925
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 478-480 33rd Avenue in San Francisco's Outer Richmond neighborhood, owned by Jasmin Luc and Zhao Min Ying, was constructed in 1925 and has experienced several significant maintenance and safety-related events in recent years. Most notably, the property has undergone substantial window improvements, with three separate window replacement projects between 2020-2021 totaling over $50,000 in upgrades. The building faced serious housing code violations in 2016, with multiple issues including plumbing problems, staircase safety concerns, and smoke detector deficiencies, though these were all resolved by March 2017. A series of fire safety violations between 2019-2023 have been documented, with the most recent being a sleeping area requirement violation issued in December 2023. The property has also seen infrastructure improvements, including electrical upgrades in 2020 with the installation of new circuits, bathroom fans, and a sub-panel, as well as plumbing enhancements with washer/dryer installations in multiple units.

Recent maintenance concerns have persisted, with multiple 311 calls in 2024 regarding sanitation issues near the property. The building's fire safety systems have required regular attention, with violations related to extinguishers and alarm systems being issued and subsequently corrected between 2019 and 2023. A notable plumbing incident occurred in February 2024 involving a sewage backup. The property underwent various improvements in 2020/2021, including bathroom ventilation upgrades, electrical system enhancements, and the installation of a mini-split system, demonstrating ongoing efforts to maintain and upgrade the building's systems. While many historical violations have been resolved, the pattern of recurring fire safety issues and recent plumbing concerns suggest ongoing maintenance challenges.

Risk rating

How 478-480 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
96thpercentile

Out of 1040 buildings in this neighborhood, 42 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
