Rent & eviction protection

Is 39-43 Auburn 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.

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 three-unit, three-story building located at 39-43 Auburn Street in San Francisco's Nob Hill neighborhood was constructed in 1906 and is currently owned by Leung Chiman & Yiyi. Over the past seven years, the property has experienced minimal formal complaints and violations, with only one Department of Building Inspection (DBI) complaint and six DBI Notices of Violation recorded during this period. The most significant recent activity involves multiple service requests in July 2026 related to scooter management and sidewalk blocking, with a total of five municipal transportation agency requests concerning scooters and two blocked sidewalk incidents (one with a seated scooter and one with a standing scooter), though all these cases have been resolved. Additionally, there was one service request regarding loose garbage and debris, which was determined to be a duplicate case.

While the building's violation history appears relatively limited, with no recent building safety concerns noted in the available data, the recent cluster of transportation-related service requests suggests ongoing challenges with public space management in the immediate vicinity. The focus of these service requests has primarily been on issues external to the building itself, particularly involving shared transportation devices and sidewalk accessibility. The property's historical record shows it was built in 1906, making it over 117 years old as of 2023, and it has maintained a consistent three-unit configuration throughout its history.

Risk rating

How 39-43 Auburn 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
73rdpercentile

Out of 1125 buildings in this neighborhood, 304 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.

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.
