Initial analysis

The two-unit residential building at 450-452 35th Avenue in San Francisco's Outer Richmond neighborhood, owned by the Chee Mee Chin Wong Trust, has undergone several maintenance and improvement projects since its construction in 1980. Most recently, in November 2024, the building received a substantial roofing renovation valued at $27,300. The property has seen consistent window upgrades over the years, with installations of vinyl windows and patio doors occurring in 2003 (12 windows), 2008 (8 windows and 2 patio doors), and the most recent work in 2020 involving gas pipe replacements. Other notable improvements include exterior work in 2005 to replace shingles with stucco on both units, and a plumbing upgrade in 2013 involving water heater replacement.

The building's maintenance history shows attention to both structural and safety improvements, including a gas pipe replacement from the exterior meter to the interior building in 2020, though one plumbing permit from 2013 has expired. A building complaint was filed in 2011 regarding an unpermitted backyard addition, though this issue was not active beyond June 2011. The property has experienced multiple parking-related incidents in recent years, with six documented cases of sidewalk parking between 2017 and 2023, resulting in citations in some instances. Street cleaning and maintenance issues have been reported through 311 calls, including general cleaning needs and a pavement defect report in 2013, though most of these cases were resolved promptly.

Risk rating

How 450-452 35Th 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 1040 buildings in this neighborhood, 83 are predicted to be safer.
