Initial analysis

The two-unit residential building at 4075-4077 Mission Street in Bernal Heights, owned by John David Lau, was constructed in 1965 as a two-story flats and duplex structure. The property has undergone several documented improvements over the years, including window and door replacements in 2002 (costing $6,883) and an electrical upgrade in 2003 involving an underground service conversion with two meters. These upgrades show attention to maintaining and modernizing the building's infrastructure.

Recent maintenance and safety concerns have emerged, particularly regarding the sidewalk conditions. An open case from April 2021 remains outstanding concerning a lifted sidewalk, which could pose accessibility or safety concerns. The property has experienced recurring issues with garbage and debris on the adjacent street areas, with multiple 311 calls between 2020 and 2024 reporting various types of waste, including paint spills and abandoned appliances. A November 2024 report noted exposed pole wires, though this appears to be a street infrastructure issue rather than a building concern. The building has also faced some surface-level maintenance challenges, including a December 2023 incident of non-offensive graffiti, which was addressed with a Notice of Violation.

Risk rating

How 4075-4077 Mission 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.
