Rent & eviction protection

Is 622-624 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 1940

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 1940
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 622-624 33rd Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1940 and currently owned by Kitty Kit Yee Shum. The building has undergone several significant renovations, with the most recent work completed in December 2024 focusing on repairs to exterior wooden stairs affected by dry rot, costing $3,000. A notable and concerning incident occurred in December 2024 when a building complaint was filed regarding possible illegal construction work being performed on the fire escape, with reports of continuous loud noise and safety concerns; this complaint was investigated and abated within ten days.

Earlier substantial improvements were made to the property in 2007, including a comprehensive remodel of both units' bathrooms and kitchens, addition of a new bathroom on the second floor, and upgrades to the water heater and furnace, with associated plumbing and electrical work totaling approximately $25,000. The building has a history of parking-related issues in the vicinity, with several complaints about vehicles blocking sidewalks or driveways between 2012 and 2021, though these were external matters not directly related to the building's condition. A false fire alarm was recorded at the address, but no injuries were reported. The property appears to be generally well-maintained, with the most recent repairs addressing specific deterioration issues, though the December 2024 construction complaint raises some concerns about proper permitting and safety protocols.

Risk rating

How 622-624 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
69thpercentile

Out of 1040 buildings in this neighborhood, 322 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
