Initial analysis

The three-unit multi-family residential building at 773-777 San Jose Ave in Bernal Heights, owned by Alfonso and Stephanie Fonseca, has a notable history dating back to its 1908 construction. The most significant recent renovation occurred in 2010 following a fire incident, involving comprehensive repairs including ceiling and wall work, slab patching, kitchen and bathroom remodeling, and extensive electrical upgrades including a new 60-amp sub-panel and multiple circuit installations, with costs exceeding $34,000. Prior to this, in 2006, the owners undertook work to remove an unauthorized ground floor unit and properly sheetrock garage walls and ceilings. The property experienced several maintenance challenges around 2009, including plumbing issues with a disconnected waste stack and water leakage in the garage, which resulted in multiple violation citations that were abated by June 2009. A routine housing inspection was conducted in 2017, though no current violations are noted.

The building's recent history (2021-2024) has primarily involved typical urban maintenance issues, including occasional reports of encampments in the vicinity, parking violations, and general sidewalk cleaning needs. A significant sewer backup was reported in August 2021, which was resolved. The most recent building-related service calls have generally concerned exterior maintenance matters, with no major structural or safety issues reported in recent years. While historical violations and repairs suggest past concerns about building systems, the property appears to be maintaining compliance with current housing codes based on available inspection records, with most recent service requests being related to external issues rather than building-specific problems.

Risk rating

How 773-777 San Jose 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
