Rent & eviction protection

Is 893 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 1951
2 or more units

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 1951
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 two-unit residential building at 893 Corbett Avenue in Twin Peaks is a two-story flats and duplex structure built in 1951, currently owned by David & Jennifer Lee 2008 T. The building's maintenance history shows three significant repairs over the past several decades: a reroofing project completed in 1997, a kitchen remodeling in 1988, and repairs to rear stairs in 1984.

More recent concerns have centered around public safety and maintenance issues, particularly affecting access to the property. The past year (2023-2024) has seen multiple reports of parking violations, including five documented cases of vehicles blocking driveways between April and May 2024, with one resulting in a citation. Of particular note is an April 2024 report of a lifted sidewalk, which though acknowledged by the Department of Public Works (DPW) as an unaccepted street issue, still represents a notable infrastructure concern. Multiple reports between October and December 2023 documented defects in public stairways and sidewalks, including a damaged wooden staircase. The building has experienced two fire-related incidents in recent years - one involving a carbon monoxide detector activation with no CO detected, and another involving outside rubbish that was also confirmed to be non-injury related. Additional reported issues in 2023 include instances of graffiti (February), human or animal waste (August), and a garbage and debris incident involving electronics (July 2024). While the building has maintained basic functionality as evidenced by the completion of various repair permits, the recent pattern of parking violations and infrastructure maintenance issues suggests ongoing challenges with property access and public space management in the immediate vicinity.

Risk rating

How 893 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
95thpercentile

Out of 172 buildings in this neighborhood, 9 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 location

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Building age

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