Noe Valley, SF 94110 6616001 5 units · 3 fl · 1913

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 5-11 28Th 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.

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 1913
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 subject property at 5-11 28th Street is a three-story, 5-unit multi-family residential building constructed in 1913, currently owned by Claudia C. Kardzair. The building has undergone several significant improvements over the past two decades, most notably including sewer line repairs in 2013, rear stair replacements in 2005, and various restaurant-related modifications between 2002-2014. The restaurant space underwent multiple changes, with permits issued for installing equipment and infrastructure including a hood system, exhaust fan, grease trap, and gas lines, culminating in a 2014 change of use approval from limited restaurant to full restaurant status with a Type 41 ABC license.

The building has experienced typical urban challenges over the years, with documented routine housing inspections in 1996, 1999, and 2008, the latter revealing a fire safety issue that was promptly resolved within a month. More recently, the property area has faced several maintenance issues, including reported sewage backup (January 2023), graffiti removal (January 2023), and multiple street cleaning matters (most recent in December 2024). Urban forestry concerns have emerged in late 2024 regarding tree maintenance. The building's safety record is generally clean, with no reported fire incidents resulting in civilian injuries, though there have been documented non-building fires and vehicle accidents in the vicinity. The property has complied with various municipal requirements throughout its history, including completing necessary repairs and addressing safety violations in a timely manner.

Risk rating

How 5-11 28Th 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
37thpercentile

Out of 1879 buildings in this neighborhood, 1184 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
