Initial analysis

The property at 878-880 31st Avenue in San Francisco's Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1931, currently owned by Peggy P Lu. The building has undergone significant and comprehensive renovations in 2023, including simultaneous kitchen and bathroom remodels in both units (with $100,000 allocated per unit), window replacements, insulation upgrades, electrical rewiring, and plumbing improvements. The electrical work included a major service panel upgrade to 400-amp with three meters, while plumbing improvements encompassed various bathroom and kitchen fixtures, including new laundry facilities. The building's roof was recently replaced in July 2023 at a cost of $22,000.

Historical records show earlier maintenance issues that have been addressed, including termite and dry rot repairs in 1992, earthquake damage repairs and restucco work in 1990, and a previous reroofing attempt in 1998. More recent infrastructure challenges included sewage backup incidents in both May and October 2022, and October 2023, though these were resolved by PUC Sewer Operations. The property has experienced recurring parking enforcement issues, with several documented complaints about driveway blocking between 2021 and 2024, though these typically resulted in no violations being confirmed. A noise complaint was filed in November 2023 and an emergency sewer vent issue was reported in October 2023. One notable recent improvement was the installation of gas insert fireplaces in May 2023 for both units, completed under proper permits.

Risk rating

How 878-880 31St 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 45 are predicted to be safer.
