Rent & eviction protection

Is 11 Broderick 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.

Built before 1979
Built 1900
2 or more units
5 units
Property type
Multi-Family Residential
Zoning
RH3
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1900
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 5-unit, 2-story multi-family residential building at 11 Broderick Street in Buena Vista Park, owned by the Blanz Revocable Trust, was constructed in 1900 and has undergone several significant maintenance and safety improvements over the years. Most notably, the building completed its mandatory soft-story retrofit in 2023, bringing it into compliance with San Francisco's earthquake safety requirements, for which a Certificate of Final Completion was issued. Recent infrastructure updates include the installation of new gas lines to units 2, 3, and 4 in 2015, and the completion of a reroofing project in 2009. The building had a series of sewer-related issues in 2021, including multiple sewage backup incidents in June and July, which were resolved by PUC Sewer Operations. Historical violations from 2002 included various safety-related issues such as stair repairs, gas utility safety requirements, and security improvements, all of which were subsequently abated.

The property has maintained regular compliance with housing inspections, though it experienced some maintenance challenges in recent years. In addition to the completed soft-story retrofit, recent building permits indicate ongoing maintenance, including a 2018 street space permit and the 2023 final inspection of previously approved work. The building had a few external maintenance issues documented through 311 calls, including tree concerns (2021) and flooding incidents, which were addressed by city services. A water or steam leak incident is recorded in the fire incident section, but no civilian injuries were reported. The property's compliance history shows a pattern of addressing mandatory requirements and maintenance issues, with all recent major safety improvements properly completed and documented.

Risk rating

How 11 Broderick 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
13thpercentile

Out of 351 buildings in this neighborhood, 305 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
