Rent & eviction protection

Is 551-555 Duboce 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 before 1979
Built 1906

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 1906
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 9-unit, 3-story multi-family residential building at 551-555 Duboce Avenue, built in 1906, has undergone significant safety and modernization improvements, particularly in recent years. The property completed its mandatory soft-story seismic retrofit program requirements and received its Certificate of Final Completion. Recent major upgrades include a comprehensive fire alarm system replacement in 2023 to comply with current fire code requirements, the installation of new sprinklers throughout the ground floor, and the addition of an ADU in the basement. The building has experienced recurring fire alarm system issues, with violations noted in 2024, 2021, and 2018, though most were promptly corrected. Historical concerns included a 2016 mold complaint, 2014 lead paint handling issues, and various fire safety violations in the early 2000s, all of which have been addressed. The property underwent substantial improvements between 2016-2024, including unit renovations, electrical updates, and infrastructure upgrades, with the most recent work focusing on fire safety compliance and ADU construction. Recent 311 calls from 2024 primarily relate to exterior maintenance and parking issues, though these are generally typical for the area and not directly related to building safety or habitability.

Risk rating

How 551-555 Duboce 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
6thpercentile

Out of 287 buildings in this neighborhood, 270 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
