Rent & eviction protection

Is 407-409 35Th 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

Just-cause eviction

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 three-story, two-unit multi-family residential building at 407-409 35th Avenue in the Outer Richmond district, owned by the Linda Quan 2008 Revoc Trust, has experienced several significant events in recent months. Most notably, in October 2024, multiple building violations were issued regarding an unauthorized roof installation over the exterior stairwell on the north side of the building, measuring approximately 100 square feet. This violation, which triggered monthly monitoring fees, was addressed through a permit process costing $12,000 in December 2024, though the status remains suspended as of October 2023. Additionally, there were concerns in October 2024 regarding exterior paint work that allegedly generated paint chips and potential lead paint concerns, leading to multiple housing inspection complaints.

The building has undergone several documented improvements over the years, including bathroom repairs and cosmetic updates in 2013 ($4,000), north side siding overlay and painting in 2012 ($4,000), and aluminum window installation in 1983. A recent fire incident investigation revealed one fire event categorized as "other" with intentional ignition, though no civilian injuries were reported. Between April and November 2024, there were multiple 311 calls related to the property, primarily concerning garbage and debris issues on public property, though these were generally resolved promptly. The building's current status shows an open planning appeal regarding the stairwell roof installation violation, indicating ongoing administrative review of this structure modification.

Risk rating

How 407-409 35Th 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
71stpercentile

Out of 1040 buildings in this neighborhood, 302 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.
