Initial analysis

The property at 622-624 33rd Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1940 and currently owned by Kitty Kit Yee Shum. The building has undergone several significant renovations, with the most recent work completed in December 2024 focusing on repairs to exterior wooden stairs affected by dry rot, costing $3,000. A notable and concerning incident occurred in December 2024 when a building complaint was filed regarding possible illegal construction work being performed on the fire escape, with reports of continuous loud noise and safety concerns; this complaint was investigated and abated within ten days.

Earlier substantial improvements were made to the property in 2007, including a comprehensive remodel of both units' bathrooms and kitchens, addition of a new bathroom on the second floor, and upgrades to the water heater and furnace, with associated plumbing and electrical work totaling approximately $25,000. The building has a history of parking-related issues in the vicinity, with several complaints about vehicles blocking sidewalks or driveways between 2012 and 2021, though these were external matters not directly related to the building's condition. A false fire alarm was recorded at the address, but no injuries were reported. The property appears to be generally well-maintained, with the most recent repairs addressing specific deterioration issues, though the December 2024 construction complaint raises some concerns about proper permitting and safety protocols.

Risk rating

How 622-624 33Rd Ave'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.
