Rent & eviction protection

Is 524 30Th 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 1971
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 1971
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 four-story, 23-unit apartment building at 524 30th Avenue in the Central Richmond neighborhood, currently owned by David S Isaac Tr and built in 1971, has undergone several significant improvements and faced various maintenance challenges over the past decades. Most notably, the building completed a mandatory soft-story retrofit in 2016 (costing $78,000) that included concrete moment frames and reinforcing steel, achieving compliance with seismic safety requirements. Recent maintenance includes the installation of a new domestic hot water boiler in June 2024. The building has also seen improvements in its fire safety systems, though issues persist, with an open violation as of November 2023 related to sleeping area requirements, and previous violations in 2016 concerning sprinkler systems and alarm systems that were eventually addressed. Historic upgrades include window replacement (2013), garage door resizing, and various plumbing and electrical improvements.

The property has experienced multiple compliance challenges over its history, with clusters of violations and complaints in specific periods. A series of fire safety and electrical issues were documented in 2004, and there was a notable incident in 1994 regarding unauthorized bathroom facilities in unit #203. More recent years have shown continued attention to building systems, particularly regarding the boiler, with violations in 2022 and 2023 related to permit requirements. The building's management has generally addressed violations within reasonable timeframes, though some recent fire safety issues remain unresolved. External maintenance concerns have been documented through 311 calls, including noise reports and requests for tree pruning, though these are typically municipal issues rather than building management concerns.

Risk rating

How 524 30Th 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
1stpercentile

Out of 2250 buildings in this neighborhood, 2228 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
