Rent & eviction protection

Is 1855 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.

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.

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 multi-family residential building at 1855 30th Avenue in San Francisco's Central Sunset neighborhood, owned by Sua Far & See Chow Lee 2015, was constructed in 1939 and has undergone several significant modifications over the past decade. Most notably, in 2015 efforts were made to legalize an in-law unit on the first floor, adding one bedroom and one bathroom, which was subsequently documented through various permits including electrical work (30 lights, switches, and receptacles) and plumbing modifications (new bathroom and kitchen). The building has experienced recurring fire alarm system issues, with documented violations in 2010 and 2021 related to system maintenance, though no civilian injuries were reported in associated fire incidents. Recent concerns from January 2025 include multiple reports of garbage and debris on the street, though these appear to be external to the building itself.

The property has also seen substantial administrative changes, including an address modification in 2015 that was formally documented in 2017. While the building has experienced various maintenance and compliance issues over the years, most have been addressed promptly and no recent major safety concerns have been reported. The most current activities include a completed gas houseline extension in January 2024 and various work completed in 2017 to properly establish the additional unit, including electrical, plumbing, and permit documentation.

Risk rating

How 1855 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
39thpercentile

Out of 814 buildings in this neighborhood, 497 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
