Rent & eviction protection

Is 231-233 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.

Built 1910

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.

15+ years since occupancy
Built 1910
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 231-233 11th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story residential building constructed in 1910, currently owned by Do Good LLC. The building has undergone significant renovations and safety upgrades over the past several years, most notably the installation of a comprehensive fire safety system in 2021-2023 that includes a new sprinkler system, fire alarm control unit, wireless communicator, smoke detectors, and manual pull stations, with associated costs totaling nearly $50,000. In 2022, the building underwent substantial interior modifications including kitchen and bathroom reconfigurations, window replacements, and the addition of a patio door. The property also underwent major structural work in 2021-2022, including the addition of roof dormers and conversion of attic space into habitable areas.

The building has faced some challenges, most notably an interior demolition without proper permits in 2020 that resulted in violation notices, though this issue was eventually abated in late 2024. Recent plumbing updates include sewer and house trap replacement and new gas line installations in 2023-2024, while electrical improvements from 2021 include complete rewiring of both units with new panels and extensive lighting, appliance, and safety system installations. Historical records from the late 1990s show previous maintenance issues with garage doors, water heater, and refrigerator, but these were promptly addressed. The building's recent maintenance history appears generally positive, with the most recent work focusing on plumbing infrastructure improvements and continued maintenance of fire safety systems.

Risk rating

How 231-233 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
94thpercentile

Out of 1723 buildings in this neighborhood, 103 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building age

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