Rent & eviction protection

Is 437-439 Plymouth 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.

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 two-unit multi-family residential building at 437-439 Plymouth Avenue, located in the Oceanview neighborhood, is a two-story flats and duplex structure built in 1906, currently owned by Liao Junchu and Liu Mian Zuan. The property's documented improvements include the installation of vinyl siding on one side of the house in 2000 (permit expired), and a solar panel installation in 2011 consisting of 5 roof-mounted PV modules with a total rating of 1.17 kW, which was successfully completed.

The building has experienced numerous municipal service calls over the past year, with the most frequent issues being related to parking violations, including multiple instances of driveway blocking and sidewalk parking between October 2024 and January 2025. Environmental concerns have been notable in recent months, with several reports of garbage and debris, including an instance of a mattress being dumped (resolved), and ongoing issues with park service area trash dumping (open). As of late 2024, there are two open cases that require attention: one regarding an overgrown tree near communication lines (accepted) and another concerning general park service area maintenance. The building's location has been affected by various parking enforcement challenges, though most of these cases were either unable to be validated or resolved through official citations.

Risk rating

How 437-439 Plymouth 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
65thpercentile

Out of 79 buildings in this neighborhood, 28 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.

Neighborhood (ZIP code)

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

Building age

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