Initial analysis

This 2-story, 5-unit multi-family residential building located at 5211 Mission Street in the Croker Amazon neighborhood was built in 1956 and is currently owned by the Ah Wong Revocable Trust. The property has undergone significant improvements and changes over the past several years, with particular attention to safety and modernization. Most recently, in September 2023, the building received fire alarm system upgrades to comply with current safety standards, including the installation of new low-frequency sounders in sleeping areas. The building underwent major modifications in 2016-2019, including the legalization of an additional unit, installation of fire sprinklers, and comprehensive renovations to multiple units including kitchen and bathroom upgrades. The property faced several maintenance challenges in the early 2000s, with multiple housing code violations identified in May 2000 related to fire safety, security, and building systems, though all were abated by April 2001.

Recent records indicate ongoing attention to building safety systems, with fire alarm and sprinkler monitoring system installations in 2019 and 2023, as well as electrical service upgrades to 200 amps in 2019. The building has experienced occasional issues with its fire alarm system, having been the subject of three malfunction-related fire department responses, though no civilian injuries were reported in these incidents. Parking-related complaints have been a recurring issue near the property, with numerous reports of blocked driveways between 2020 and 2025, though enforcement officers often found the vehicles to be unreachable. The building's maintenance history shows a pattern of addressing both routine updates and specific tenant needs, such as the 2016 kitchen and bathroom remodels in Unit 4 valued at $35,000, and various plumbing and electrical system upgrades throughout the building.

Risk rating

How 5211 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.

Neighborhood percentile
