Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 332-334 Frederick 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 1905
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 1905
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 332-334 Frederick Street property is a 2-story, multi-family residential building constructed in 1905 in the Haight Ashbury neighborhood, currently owned by Klots Family Trust. The building underwent significant renovations between 2013-2014, including complete plumbing system replacement, electrical upgrades, and window/door improvements. Major improvements included the installation of a new fire sprinkler system throughout the garage and residential units in April 2013, comprehensive bathroom and kitchen remodels in all units, and window replacements on both the front facade and east alley. The electrical system received substantial upgrades with new subpanels, lighting, and appliance installations across all units. While there were some historical violations and complaints in the early 2000s related to plumbing, electrical, and smoke detection issues, all were resolved by 2005. A 1998 complaint regarding utility metering was also resolved, indicating previous concerns about unit count and metering were addressed.

Recent activity at the property has been limited to routine maintenance and management of external issues. The most notable recent concern was a collapsed sidewalk reported in March 2024, which was subsequently repaired. Minor issues such as toters being left out, illegal parking, and trash-related complaints have been addressed through normal municipal processes. The building's major systems have been significantly upgraded over the past decade, including the addition of fire sprinklers, new HVAC systems, comprehensive plumbing updates, and electrical system modernization, suggesting current compliance with safety and building codes. While there have been periodic issues with illegal parking and sidewalk maintenance in the vicinity, these are typical of urban properties and do not directly reflect on the building's condition or management.

Risk rating

How 332-334 Frederick 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
55thpercentile

Out of 581 buildings in this neighborhood, 261 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
