Rent & eviction protection

Is 440-442 Green St 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 1907
2 or more units

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 1907
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 440-442 Green Street property in Telegraph Hill is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by Chin Howk Hong Wong Fei Fon. The building's permit history shows minimal recent maintenance activity, with only two street space permits issued in 2007 and 2016, and a now-expired permit from 1993 for bathroom and kitchen repairs on both floors. The most significant recent issue has been an ongoing problem with garbage and debris management, with multiple 311 calls recorded between 2024 and 2023 regarding abandoned furniture and other debris. Of particular concern are nine separate reports of illegal sidewalk parking between August and November 2024, with several resulting in citations, though many officers were unable to locate the offending vehicles when responding.

A building complaint filed in March 2019 reported issues with tenant access and trash bin placement impacting sidewalk access, though this case is currently marked as not active. The only fire incident on record involved a malfunctioning alarm system, with no civilian injuries reported. While the building has maintained its original class as Flats & Duplex, the permit history suggests limited recent interior improvements or maintenance. The high frequency of parking-related incidents in recent months may indicate ongoing challenges with the building's surrounding infrastructure and accessibility.

Risk rating

How 440-442 Green St'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
66thpercentile

Out of 684 buildings in this neighborhood, 233 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.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
