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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 287 buildings in this neighborhood, 66 are predicted to be safer.

Model explanation

What's driving this score

Building age

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 64.5%
Moderate concern 20.7%
Severe concern 14.7%
