Rent & eviction protection

Is 275-277 Oak 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 1900

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 1900
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 275-277 Oak Street property is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1900 and currently owned by Nobuth Prithvi & Patel Kirt. The most significant recent development occurred between 2018-2020 when the building underwent major improvements including the addition of two ADU units in the ground floor garage and storage area, installation of a complete sprinkler system, and substantial plumbing and electrical upgrades. The project included voluntary seismic improvements and was completed with a total investment of approximately $190,550. More recent maintenance and compliance work has been conducted in 2020, including furnace replacements, water heater installations, and electrical upgrades, with the most recent building inspection-related work completed in late 2020 to comply with inspection report CC-8465.

The building's history reveals several maintenance and safety concerns, with the most serious being an active housing complaint from 1995 regarding a bathroom ceiling collapse with potential electrical concerns, as well as multiple plumbing-related issues in 2005 involving sewer concerns that were promptly addressed. The property has had some fire safety incidents, including two false alarms in 2021 and a sprinkler system issue that was corrected in July 2021. Recent records from 2025 show multiple reports of garbage and debris issues near the property, though these are street-related matters and not directly concerning the building itself. The property's infrastructure upgrades, including the 2018-2020 sprinkler installation and ADU additions, suggest significant investment in improving the building's safety and living conditions, though ongoing maintenance issues like the 1995 ceiling collapse complaint and recent street cleaning needs indicate that some areas still require attention.

Risk rating

How 275-277 Oak 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
63rdpercentile

Out of 1027 buildings in this neighborhood, 380 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
