Rent & eviction protection

Is 2224-2230 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.

Built before 1979
Built 1904
2 or more units
30 units
Property type
Multi-Family Residential

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 1904
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 3-story, 30-unit multi-family residential building at 2224-2230 Union Street in Cow Hollow, owned by East-west Generations, has undergone significant renovations and maintenance since its construction in 1904. The building has completed its soft-story retrofit and received a CFC certification. Recent improvements include a comprehensive electrical panel upgrade in 2024 for units 102-214, installation of low-frequency sounders, and fire alarm control panel replacement in 2021, demonstrating ongoing commitment to safety systems maintenance. The property has a history of addressing unit upgrades systematically, with multiple apartment renovations completed between 2017-2022, including kitchen and bathroom remodels in units 107, 112, 207, and others.

However, there have been persistent fire safety concerns, with multiple violations issued for alarm system maintenance, sprinkler service requirements, and emergency lighting since 2023. Recent building violations in 2023 related to an unpermitted boiler operation were abated, though there have been recurring issues with the fire alarm system requiring attention. The building experienced a period of vacancy in early 2023, resulting in complaints about compliance with the vacant storefront ordinance. Historical complaints from 2017 regarding unauthorized penthouse living quarters without elevator access were eventually resolved, and the property now meets Tier 4 soft-story requirements. The building's maintenance history shows regular attention to infrastructure needs, including a 2018 reroofing project and various plumbing upgrades, though some 311 calls in 2024 indicate ongoing exterior maintenance concerns such as sidewalk conditions and debris management.

Risk rating

How 2224-2230 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
0thpercentile

Out of 861 buildings in this neighborhood, 861 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
