Rent & eviction protection

Is 104-106 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 1961

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 1961
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 property at 104-106 Corbett Avenue is a two-unit, two-story multi-family residential building located in the Corona Heights neighborhood, owned by Jasmine Yee Hing Leung and constructed in 1961. The building's history reveals significant concerns about unauthorized unit conversions and safety compliance, particularly during the early 2000s. A major incident occurred in 2004 when an illegal basement unit was discovered, containing two bedrooms, kitchen, bathroom, and living areas, constructed without permits and lacking proper fire protection - this violation was abated in September 2004 through a series of permits that legalized the basement bedroom, including electrical work and a $3,000 building permit. The building has also undergone various infrastructure updates, including gas houseline extensions in 2007, the installation of a grounding wire in 2005, and earlier projects in the 1980s for fungus damage repairs.

More recent history shows continued concerns about unauthorized modifications, with multiple complaints in 2006-2014 regarding possible illegal units in the garage and basement, though these complaints were eventually closed. Building systems have seen improvements through several permits, including electrical upgrades and plumbing work. The property has experienced some safety issues, including two fire-related incidents in June 2010 (one involving blocked exits and another related to a contained cooking fire), though no civilian injuries were reported. Recent maintenance and environmental concerns have been documented through 311 calls, including reports of graffiti, tree-related property damage, sewer odor, and multiple instances of garbage and debris issues in 2023-2024. While many historical violations have been addressed, the pattern of unauthorized unit modifications and safety-related incidents suggests ongoing challenges with building code compliance and maintenance standards.

Risk rating

How 104-106 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
78thpercentile

Out of 348 buildings in this neighborhood, 77 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
