Rent & eviction protection

Is 824 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 1968

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

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 1968
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 5-unit, 2-story multi-family residential building at 824 Corbett Ave in Twin Peaks, owned by Gaehwiler 2000 Trust and constructed in 1968, has undergone several significant improvements and faced various maintenance challenges over the past two decades. Most notably, the building completed its mandatory soft-story retrofit in 2017 at a cost of $100,000, addressing earthquake safety requirements. Recent safety improvements include the installation of a new fire alarm system in 2022 (costing $13,921) and the replacement of kitchen cabinets and countertops in unit #3, along with associated electrical and plumbing upgrades, completed in 2017. The building has maintained its infrastructure with multiple utility updates, including water heater replacements in 2013 and 2014, and a furnace replacement in unit #5 in 2011.

The property has experienced some code compliance issues, most notably regarding the soft-story retrofit program, which generated complaints in 2019 that were ultimately resolved by September 2021 when the work was completed and a Certificate of Final Completion was issued. Historical violations from 2003 related to fire escape and rear deck issues were also resolved. While there have been multiple parking enforcement calls in recent years (2023-2024) regarding vehicles blocking sidewalks or driveways, these are external issues not directly related to building maintenance or safety. The building's maintenance record shows regular upkeep, including a reroofing project in 2017 and various unit-specific improvements. The property has experienced minimal fire-related incidents, with only one minor alarm system issue recorded in 2009 that was promptly corrected.

Risk rating

How 824 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
72ndpercentile

Out of 172 buildings in this neighborhood, 48 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Number of units

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

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location
