Rent & eviction protection

Is 2319 21St 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 1927

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.

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 Parkside duplex at 2319 21st Avenue, owned by Leung Yan & Yim Fong Truste, is a two-story multi-family residential building constructed in 1927. The property has undergone two significant modifications over its lifetime: in 1993, a $12,000 renovation was completed to legalize rooms on the first floor in response to a violation notice, and in 1984, aluminum windows were installed in existing frames.

The most notable recent issue affecting the property has been a persistent pattern of driveway blocking incidents, particularly throughout 2022 and continuing into 2023-2024. The building's owners have filed multiple complaints about unauthorized parking, with at least five documented instances resulting in citations being issued between April and September 2022 alone. More recently, there were three documented parking enforcement requests in 2023-2024, including one case involving a black Subaru XV Crosstrek in August 2023 where officers were unable to locate the vehicle, and another in September 2024 that was declared invalid due to incomplete reporting information. While these parking issues are primarily enforcement matters, they suggest an ongoing challenge with parking management in the immediate vicinity of the building, though it's worth noting that the majority of these complaints have been resolved through proper channels with varying levels of enforcement response.

Risk rating

How 2319 21St 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
70thpercentile

Out of 255 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.
