Initial analysis

The three-story multi-family residential building at 331 18th Avenue in the Central Richmond district, owned by Lee Toy & May S Kwong Revoc, has undergone several significant renovations and repairs since its construction in 1982. Most notably, in 2021, the building experienced water-related issues requiring repairs to multiple bathrooms, with work totaling approximately $100,000 and involving plumbing and electrical upgrades. The building's exterior has seen substantial maintenance work, including a complete bathroom remodeling in Unit A ($12,500) in 2021, re-roofing completed in early 2024 ($12,000), and several siding repairs between 2010-2018 to address water damage and leaks. A potentially concerning incident occurred in 2009 regarding inadequate hot water supply and safety hazards with the water heater, though this was promptly addressed within two weeks. A noise complaint was filed in 2020 related to construction work, which was officially addressed by the Building Inspection Division.

The property has been subject to multiple parking enforcement calls, particularly regarding sidewalk parking violations, with several citations issued in 2019-2022. There were historical maintenance issues in the late 1990s, including reports of water stains, ceiling cracks, and window problems, though these appear to have been resolved. While the building has required regular maintenance and experienced periodic water-related issues, the recent completion of significant bathroom and roofing upgrades, along with prompt responses to safety concerns, suggest active management of the property. Recent parking enforcement actions indicate ongoing issues with unauthorized parking in the vicinity of the building, though these are not directly related to building management.

Risk rating

How 331 18Th 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
