Rent & eviction protection

Is 681 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 1975

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 1975
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 7-unit, 2-story multi-family residential building at 681 Corbett Avenue, owned by Raymond Yang and constructed in 1975, has undergone several significant renovations and faced various maintenance challenges over the years. Most recently, in 2024, there have been multiple complaints filed regarding unit leaks, water damage, pests, electrical issues, and mold problems, particularly in Unit 2 since 2014. The building experienced notable construction activity in the early 2000s, including a major interior remodel of the top floor penthouse (Unit 7) in 2002 costing $77,000, followed by electrical upgrades in 2003-2004 that included installation of new lights and electrical plugs. However, this period also saw several permit issues, with multiple expired permits and unauthorized work, including window installations, leading to violations in 2003-2005 that were eventually abated by 2004-2005.

The building's maintenance history reveals recurring concerns with building systems and resident comfort, including a 2019 mold complaint, and more recent issues in 2024 involving water damage and ventilation problems. Historical violations from 2003-2004 related to fire escape and laundry room ventilation were resolved, and roofing work was completed in 2004. Recent 311 calls (2023-2024) around the property have primarily concerned parking issues and graffiti, though these are external to the building's structural and maintenance concerns. The building's original construction and various improvements have been documented through multiple permits, though some faced challenges with expired permits requiring renewals and additional inspections. The property appears to have undergone significant modernization efforts in the early 2000s, followed by ongoing maintenance challenges in recent years, particularly relating to water and ventilation issues.

Risk rating

How 681 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
56thpercentile

Out of 172 buildings in this neighborhood, 76 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
