Initial analysis

The property at 740-742 39th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1926. The building has undergone significant renovations and maintenance work over the past several years, with major projects completed in 2018 including a $75,000 stucco replacement and a $13,650 reroofing. The property has faced several enforcement actions, notably in 2004-2009 when violations were recorded regarding unauthorized partitions added at the ground floor level to create habitable rooms and a bathroom, which were eventually abated in 2013. Multiple vacant building ordinance violations were issued between 2009 and 2012, with issues related to debris, sanitation, and security requirements, though these complaints are now marked as not active.

The building has undergone substantial improvements to its infrastructure, including a foundation replacement and wood girder replacement in 2017, electrical system upgrades to 200 amps, and plumbing renovations involving bathroom additions and waste line replacements in 2012. Historical records show past permit expirations and compliance issues, particularly in 2004-2008 when several building permits were found to be expired or requiring renewal. Recent activity at the property includes a sewage backup incident reported in October 2023, which was resolved, and various parking enforcement issues in the surrounding area. The building's records demonstrate a pattern of renovation, compliance challenges, and subsequent resolutions, with the most recent major building work focusing on exterior maintenance and infrastructure upgrades.

Risk rating

How 740-742 39Th 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.
