Initial analysis

The 5255-5259 Mission Street property is a two-story mixed-use building constructed in 1929, containing 3 multi-family residential units and ground-floor commercial space, currently owned by the Choy Family Revocable Trust. The building has undergone several significant improvements and faced various maintenance challenges over the years. Most recently, in November 2023, accessibility improvements were completed with the installation of a power door operator to comply with the ABE program. A notable resolution in 2023 was the voluntary removal of a general advertising sign by Clear Channel Outdoor. The building's infrastructure has required attention to the sidewalk area, documented through permits in 2008-2009 for repairs and replacement of sewer lines on Allison Street, following a complaint about a collapsed sewer that created a health hazard (though this was promptly resolved within weeks). There have been recurring issues with vacant storefronts, with active complaints filed in both 2019 and 2023.

Recent months have seen a significant pattern of parking enforcement issues, particularly regarding sidewalk parking, with multiple citations issued between September and November 2024. The building has experienced several false alarms and smoke detector activations, though none resulted in injuries or actual fires. Two plumbing permits from 2008 and 2013 indicate past work on the property's infrastructure, including a gas houseline extension. The property's accessibility was recently addressed with the power door installation, showing ongoing improvements to meet current standards. A review of 311 calls from 2024 shows varied neighborhood issues, including parking violations and street cleaning needs, though these are primarily external to the building itself.

Risk rating

How 5255-5259 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.
