Rent & eviction protection

Is 619-621 Central 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 1916

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 1916
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 619-621 Central Ave in Park North, owned by Collin & Lily Chu 2020 Lvg, was constructed in 1916 as a two-story flats and duplex structure. The building's maintenance history shows limited permitted work, with a sidewalk & street space permit issued in 2008 and a reroof permit from 1998 that has since expired. More recent building records indicate only one fire-related incident, which was an unintentional detector activation with no fire or civilian injuries reported.

The property has experienced recurring challenges with street and sidewalk cleanliness between 2022 and 2024, including multiple instances of human or animal waste (January and September 2023), various types of garbage (general cleaning cases in January and October 2023), and even hazardous materials (an oil/paint-related incident in August 2022). Other documented incidents include graffiti on the sidewalk (June 2022), a noise issue during festival days (August 2022), and a water-related complaint (December 2023) that required referral to customer service. While these external maintenance issues have been addressed through appropriate channels, they represent ongoing environmental challenges in the immediate vicinity of the building.

Risk rating

How 619-621 Central 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 797 buildings in this neighborhood, 175 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.

Building age

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

Construction spend, owner's portfolio

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
