Initial analysis

The property at 4483-4485 Mission Street is a two-story mixed-use building constructed in 1922, containing two residential units and ground-floor commercial space. The building has undergone significant renovations and improvements over the past several years, with the most substantial work occurring in 2022-2024 focused on converting part of the ground floor to a limited restaurant use, including a horizontal addition with new mezzanine and associated kitchen equipment, electrical, and plumbing systems, at a total estimated cost of over $500,000. The residential unit renovations (2020) included substantial updates to the living spaces, including bathroom and kitchen remodeling, with corresponding electrical and plumbing work completed in 2021.

Recent concerns affecting the property include restaurant exhaust issues reported in 2023, and there is an active complaint from May 2023 regarding a vacant business on the property. Historical issues from the 1990s included multiple maintenance problems such as heating system failures and plumbing issues, though these appear to have been resolved. The building has had some recent maintenance needs as evidenced by multiple 311 calls in late 2024 regarding graffiti, noise, and waste management issues, as well as a sewage-related incident in June 2024. The property management has consistently filed the necessary permits for various improvements and modifications, though there have been some permit cancellations and withdrawals, such as the 2022 withdrawal of the rear yard stair removal permit.

Risk rating

How 4483-4485 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.
