Initial analysis

The property at 628-630 4th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1911 and currently owned by the An-lew Family Trust, this flats and duplex-style building has undergone several significant improvements over the past two decades. Major renovation projects include an interior remodeling in 2007 that involved relocating the kitchen and bathroom facilities (costing $25,000) and an earlier ground floor expansion in 2003 that added a bedroom, bathroom, laundry room, and storage space ($13,000). The building has also received updated electrical work corresponding to these renovations, with the 2007 project installing new bathroom and kitchen electrical systems, sub-panel, lights, and various circuits.

Recent maintenance and infrastructure issues warrant attention, particularly a sewage backup incident in December 2023 that required professional intervention. The property has experienced some recurring maintenance matters, including a dead tree removal in 2020 and previous roofing work in 2002 (though those permits show as expired). The location has faced various neighborhood challenges, as documented through 311 calls, including recent parking violations, garbage concerns, and utility service requests. While many of these issues have been resolved promptly, they suggest ongoing environmental and maintenance considerations in the surrounding area. The most recent building improvements and maintenance history show regular investment in maintaining and upgrading the property, with no major structural or safety violations recorded in the available permit and complaint history.

Risk rating

How 628-630 4Th 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.
