Initial analysis

The property at 4479-4481 Mission Street is a two-story mixed-use building constructed in 1909, containing two residential units and ground-floor commercial space. Recent significant improvements include a 2019 rehabilitation of the commercial space costing $100,000, which was completed, along with the installation of a new half bathroom and various electrical upgrades in February 2020. Historical improvements include a notable 2012 renovation that made the building more accessible, including the installation of ADA-compliant features such as a power door operator and accessible bathroom facilities. The building has undergone necessary maintenance work, including reroofing in 2005 and an ANSUL system upgrade in 2009.

The property has experienced several challenges with its commercial space, particularly between 2015 and 2020, when it faced multiple violations related to the Vacant or Abandoned Commercial Storefronts Ordinance, though these violations were ultimately abated. A complaint in 2020 questioned whether the commercial space was being converted from its legally permitted restaurant use. Recent 311 calls from 2023-2024 have primarily concerned external issues such as graffiti (currently open), garbage, and sidewalk cleaning matters, with one shared spaces violation from May 2023 remaining open. A recent planning record indicates a transition from vacant restaurant use to retail sales and service with instructional art and dance classes, along with ADA compliance work on the ground floor, which reportedly did not require notice pursuant to section 311.

Risk rating

How 4479-4481 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.
