Rent & eviction protection

Is 254 27Th 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.

Built 1959

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.

Built 1959
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 4-unit, 2-story multi-family residential building at 254 27th Avenue in the Lake --The Presidio neighborhood was constructed in 1959 and is currently owned by Rudolph A & Stephanie G Hof. The building has undergone several significant maintenance and repair works over the years, with the most recent notable improvement being a $6,000 siding repair project undertaken in December 2019, involving the installation of primed cedar siding on the building's front facade. Earlier maintenance work included a complete reroofing project in 2002 costing approximately $10,000, and more substantial repairs to address dry rot in deck support structures, though this permit ultimately expired. Historical records show routine apartment inspections in 1996, 2003, and 2007, with the latter inspection revealing multiple violations including the need for smoke detectors, ventilation for public halls, and adjustments to self-closing exterior door devices, all of which were promptly corrected by November 2007.

In terms of more recent history, there has been a pattern of parking-related issues near the property, with multiple citations issued for driveway blocking between 2021 and 2024, including two such incidents recorded in September 2024. Additional urban maintenance matters were addressed in 2021 and 2018, including the removal of encampment items and loose garbage. The building's overall record indicates regular maintenance and compliance with housing inspection requirements, with prompt responses to violations when they occur. The property has maintained its classification as a multi-family residential building throughout its history, with no significant changes to its basic structure or use.

Risk rating

How 254 27Th 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
24thpercentile

Out of 660 buildings in this neighborhood, 502 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
