Rent & eviction protection

Is 577-581 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.

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 1904
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 residential building at 577-581 Duboce Avenue in Duboce Triangle, owned by Laura B. Smith, has undergone several significant improvements since its construction in 1904. The most recent major work was completed in 2021, involving the installation of 15 high-quality Marvin wood windows with integrated features, costing $31,000, while similar window replacements were previously performed in 2015 for the back wall of the building. The property has received proper foundational attention with a 2005 improvement that included the installation of a 12"x56' foundation cap with continuous rebar on the west elevation, and an electrical upgrade was recently completed in April 2024 for the relocation of the PG&E meter light switch.

The building had a notable cluster of violations documented in a 2001 routine inspection, including issues with plumbing, fire safety (such as egress obstruction and garbage receptacle placement), and general building maintenance (including stairs and deck repairs). However, all these violations were successfully abated by February 2004. Additional historical improvements include an underground electrical service conversion in 2005 and various maintenance works such as a tub and tile replacement. Recent 311 calls from late 2024 suggest some external maintenance issues in the vicinity, including graffiti removal and garbage overflow concerns, though these are related to public infrastructure rather than the building itself.

Risk rating

How 577-581 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
77thpercentile

Out of 287 buildings in this neighborhood, 66 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
