AI summary

The two-unit residential building at 4320-4322 Irving Street in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1946, currently owned by Anna Mak-ng. The property has undergone several significant improvements over the past two decades, with the most recent major maintenance being a reroofing project completed in 2013 at a cost of $6,200. Earlier improvements include substantial renovation work in 2003, during which a new ground floor family room, bathroom, and laundry closet were constructed, along with stucco repairs to the building's facade; this renovation was accompanied by electrical upgrades including a 200-amp service installation with three meters and comprehensive wiring for the new family room and bathroom facilities.

The building's recent maintenance history shows consistent attention to structural and electrical systems, though there have been recurring issues with the property's immediate surroundings requiring municipal attention. Since 2019, there have been multiple 311 calls regarding various street and sidewalk cleaning matters, including reports of loose garbage and graffiti. More recent service requests include a hazardous materials incident in 2021 involving liquids, and a notable enforcement action in 2014 regarding improper receptacle management when waste cans were reportedly left out continuously. While these external maintenance issues have spanned multiple years and various categories, they appear to have been addressed promptly by city services, indicating an active response to neighborhood cleanliness concerns.

Risk rating

How 4320-4322 Irving 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.
