Rent & eviction protection

Is 423-425 11Th 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.

Built 1922
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 Huang/Wang Family Trust owns this two-unit residential building located at 423-425 11th Avenue in the Inner Richmond neighborhood. Built in 1922, this two-story flats and duplex structure underwent significant modernizations in 2019-2020, including comprehensive renovations to both units featuring kitchen and bathroom overhauls, installation of new water heaters and laundry facilities, and the addition of new bathrooms. The building's electrical infrastructure was notably upgraded, with the main service capacity increased from 100 amps to 200 amps in July 2022, following earlier improvements in March 2020 that included sub-panel upgrades and comprehensive electrical work related to the remodels.

The property has undergone substantial interior improvements, including the installation of new furnaces for both units in March 2020. A street space permit was issued in August 2019, and a similar permit was obtained in September 2012. The building's maintenance history includes a 2012 sidewalk repair that addressed both damaged sidewalk conditions and a loose sewer vent cover, which were properly resolved as per inspections on November 29, 2012. The recent planning record indicates interior tenant improvements focusing on window modifications, specifically replacing existing windows with double-hung and casement wood aluminum-clad windows, without any changes to unit count or sizes. The extensive renovations completed in 2019-2020 improved both units' amenities and infrastructure, modernizing the building significantly while maintaining its original residential character.

Risk rating

How 423-425 11Th 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
96thpercentile

Out of 1723 buildings in this neighborhood, 69 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
