Initial analysis

The three-story multi-family residential building at 3548 Divisadero Street, located in San Francisco's Marina neighborhood, is a two-unit structure built in 1925, currently owned by Arthur & Seraphina Leong Re. The building has undergone several significant renovation projects over the past decade, with the most substantial improvements completed between 2011-2012, including a comprehensive basement remodel, kitchen renovations, window replacements, and bathroom additions, with building costs totaling approximately $160,000. In 2021, efforts were made to restore historic character-defining features, including window sills and decorative elements, with a $15,000 permit issued for improvements including aluminum-clad window replacements. The property has received regular maintenance, including reroofing work completed in 2018 ($8,800), and various utility upgrades such as furnace installations and electrical system improvements.

Recent activity at the property has primarily involved parking-related issues, with multiple complaints about driveway blocking and sidewalk parking reported through 311 calls between 2023-2024. The building's maintenance record shows a pattern of unintentional fire alarm activations, with eight separate incidents recorded, though none resulted in any actual fires or injuries. Planning records indicate some concerns about unpermitted modifications from around 2013, including changes to the entry, garage door, windows, and architectural details, though these issues appear to be in the process of resolution. The property's location has experienced occasional infrastructure-related complaints, including one hazardous materials incident in 2023 involving liquids on the street/sidewalk, though this was promptly resolved.

Risk rating

How 3548 Divisadero 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

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
99th percentile

Out of 988 buildings in this neighborhood, 10 are predicted to be safer.
