Initial analysis

The two-unit residential building at 33 Hemway Terrace in the Lone Mountain neighborhood is a 2-story flats and duplex structure built in 1922, currently owned by the Wai John E 1981 Living Trust. Recent building maintenance includes a complete re-roofing project undertaken in December 2024, with an expenditure of $16,900, replacing existing roofing materials. The property underwent significant renovations in 2012, which initially triggered a building violation for unpermitted kitchen and bathroom remodeling, resulting in a Notice of Violation being issued on January 17, 2012, that was ultimately abated by June 20, 2012. These renovations included converting a living room into bedrooms, modifying hallways and kitchen spaces, and undertaking various electrical and plumbing updates on the second floor, with documented permit costs totaling approximately $30,000.

The building's recent history reveals ongoing noise-related concerns, with multiple excessive noise complaints recorded between June and August 2024, though these complaints currently remain open. Prior to these noise issues, there was one street space permit issued in December 2017, and a garbage-related incident involving an overflowing city garbage can near the property in August 2017, which was determined to be a private property issue with no action required. The property has undergone various infrastructure improvements over the years, including a previous re-roofing project in 1995, and the 2012 renovations were accompanied by electrical updates (replacement of lights, switches, and receptacles) and plumbing improvements (replacement of bathroom and kitchen fixtures and pipes) on the second floor.

Risk rating

How 33 Hemway Ter'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
65th percentile

Out of 519 buildings in this neighborhood, 182 are predicted to be safer.
