814 Corbett Ave

Twin Peaks, SF 94131 2779002 19 units · 3 fl · 1964

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 814 Corbett 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 before 1979
Built 1964
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1964
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

814 Corbett Avenue is a 3-story, 19-unit multi-family residential building constructed in 1964, currently owned by Gaehwiler 2000 Tr. The building has undergone significant safety and maintenance upgrades in recent years, including the completion of a soft-story seismic retrofit (Tier 2) in 2016, a voluntary fire alarm system upgrade in 2012, and various interior improvements. The property has consistently addressed safety requirements, with recent work including a sleeping area sound level verification completed in February 2024 and the resolution of a December 2023 violation related to sleeping area requirements. Major maintenance work has included window replacements, roof work, and individual unit improvements such as the recent kitchen renovation in Unit 405 (2017).

The building's history shows attention to infrastructure maintenance, with plumbing upgrades including water heater and boiler replacements in 2019 and 2015 respectively, as well as electrical system improvements such as elevator upgrades and fire alarm system integrations. Several building violations were recorded in the past, primarily related to fire safety and security concerns between 2003 and 2011, but these were all properly abated. There were also some complaints regarding unauthorized work and heating issues in 1997-2010, which were addressed at the time. The property has experienced recurring issues with parking violations in recent years, with multiple enforcement calls between 2023-2024, though these are not directly related to building safety or maintenance.

Risk rating

How 814 Corbett 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
32ndpercentile

Out of 172 buildings in this neighborhood, 117 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.

Building size

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

Number of units

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
