Rent & eviction protection

Is 431-433 9Th 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 1923

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 property at 431-433 9th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1923, currently owned by the Robert H Chee Bypass Trust. The building's maintenance history includes several significant structural and aesthetic improvements from the 1980s, including two separate kitchen remodeling projects in 1986 and 1989, and more substantial structural work in 1985 that involved repairing stud framing, installing footings, and addressing stair and door issues, though this permit expired without completion.

The property has experienced recurring issues with sidewalk maintenance and street cleanliness over the past two decades, with the most recent incidents occurring in 2024 involving garbage and debris on the street. A notable pattern of sidewalk-related problems emerged in 2013 and 2015, when the property was found to have significant sidewalk defects, including a collapse and uneven surfaces totaling approximately 59 square feet between the two incidents. While these structural issues appear to have been addressed, as indicated by the "Completed" status of the 2013 citation, similar concerns have persisted in subsequent years, with multiple reports of loose garbage on the street requiring municipal intervention. The building's permit history suggests regular maintenance and upgrades were attempted during the 1980s, though no recent permits or major improvements have been documented in the past three decades.

Risk rating

How 431-433 9Th 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
72ndpercentile

Out of 1723 buildings in this neighborhood, 482 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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

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

Building age

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