Initial analysis

The property at 839-841 30th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by Denny K Miu and constructed in 1947 in the Flats & Duplex building class. The building has undergone several significant improvements over its lifetime, with the most recent major infrastructure work occurring in 2018, including street space modifications and plumbing work involving the replacement of a section of the main lateral. A flooding incident was reported on the property in June 2023, which was promptly addressed and resolved by PUC Sewer Operations. The building has seen consistent maintenance attention to its roofing needs, with records showing reroofing work completed in 1990, 2010, and additional street space permits in 2018. Historical improvements include notable residential upgrades completed in 1989, when half baths were added to each unit along with kitchen and bathroom remodeling.

The property's history also includes several minor service calls and enforcement actions in the surrounding area, though none directly related to the building's structural integrity or resident safety. These external incidents include parking enforcement for sidewalk parking in July 2022 and an abandoned vehicle report in May 2017, both of which were resolved by city agencies. A planning record from 841 30th Avenue indicates an ABC referral for Type 09, 17, which was approved but shows no developer information. The building's maintenance record suggests regular upkeep, with no documented pattern of recurring issues or safety concerns.

Risk rating

How 839-841 30Th 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.
