Initial analysis

The two-story, four-unit multi-family residential building at 4484-4488 Mission Street, located in the Mission Terrace neighborhood, has experienced several significant maintenance and safety events since its construction in 1910. Notably, in December 2013, serious gas line safety issues were identified, with four underground gas lines in disrepair requiring replacement according to California Plumbing Code violations; these were subsequently repaired and abated by February 2014. The building underwent reroofing in 1990 and had a street space-related permit issued in 2018. More recently, there was a complaint about drilling and loud banging noises from one of the units in 2020, though this issue was resolved by January 2021.

The property has faced recurring issues with graffiti and public space maintenance, particularly between 2020 and 2024, with multiple incidents requiring government intervention. Most notably, there have been several documented instances of graffiti on the building and surrounding areas, with the most recent incidents occurring in 2023 and 2024. Public Works departments have addressed various street and sidewalk cleaning needs, including removal of offensive graffiti, human or animal waste, and loose garbage. While these surface maintenance issues persist, it's important to note that they do not directly impact the building's structural integrity or safety systems. The most significant building system intervention remains the 2013 gas line repair project, which was properly completed and inspected according to available records.

Risk rating

How 4484-4488 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.
