Initial analysis

4598 Mission Street is a three-story, five-unit multi-family residential building constructed in 1907 and currently owned by Delcamp Inv Inc. The property has undergone several significant transformations and improvements over the years, with the most notable change occurring in 2016 when the ground floor underwent a $430,000 conversion from retail to an urgent care clinic (GoHealth), accompanied by extensive interior renovations and infrastructure upgrades. This project included comprehensive electrical, plumbing, and HVAC installations, with the electrical work involving a significant upgrade to a 400-amp service with 45 circuits, and the plumbing work adding multiple new fixtures and an extensive ventilation system.

The building has seen various improvements to maintain and upgrade its facilities, including a bathroom remodel in 2020 costing $25,000, voluntary seismic strengthening work in 2012 ($120,000), and several street space permits. However, the property has experienced some maintenance challenges, as evidenced by multiple 311 calls in 2024 regarding graffiti, garbage, and debris on the property. Notably, there are records of three fire code violations from 2007 and 2010 relating to blocked exits, door issues, and emergency lighting, though these were all marked as resolved. The building has also faced periods of vacancy, as indicated by multiple vacant storefront complaints between 2019 and 2020, though these issues appear to have been addressed. Recent activity includes annual inspections and continued maintenance work, with the most recent permit being for a bathroom remodel completed in 2020. While the property has had its share of maintenance issues over the years, many have been addressed through various improvement projects and permits.

Risk rating

How 4598 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.
