Rent & eviction protection

Is 805-811 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.

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 1936
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 four-unit, two-story apartment building at 805-811 27th Avenue in the Central Richmond neighborhood, constructed in 1936, has undergone significant structural and cosmetic improvements, most notably an $18,000 foundation reinforcement project completed in 2010 that addressed serious structural concerns identified in 2007-2009. During the 2009 renovation period, the building received comprehensive updates including kitchen and bathroom remodels in units 805, 809, and 811, along with electrical upgrades for all units that encompassed lighting, wiring, and bathroom facilities improvements, with costs totaling over $45,000. The property experienced several serious issues between 2007 and 2009, including structural instability, inadequate heating, and security concerns, all of which were ultimately resolved through the various improvements and repairs carried out in 2009-2010. Since these major renovations, there have been no recorded building violations or major complaints regarding habitability or safety.

The most recent planning application proposes converting non-occupied ground floor space to living quarters and making additional bathroom modifications, indicating ongoing improvements to the property. Recent records from 2024-2025 show only minor issues, primarily related to parking violations and street cleaning matters, with multiple citations issued for driveway blocking and several cases of abandoned debris requiring sanitation services. These recent maintenance and compliance records suggest that the property management is currently maintaining the building to acceptable standards, with no recurring structural or habitability concerns similar to those experienced in previous years.

Risk rating

How 805-811 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
28thpercentile

Out of 2250 buildings in this neighborhood, 1620 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.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
