Initial analysis

The two-unit residential building at 21 Hemway Terrace, located in the Lone Mountain neighborhood, is a two-story flats and duplex structure built in 1924, currently owned by Nicolai & Vera Umanetz Life. The building's renovation history shows some maintenance activity, including a permitted bathroom renovation in 2003 costing $2,000 that involved replacing fixtures and tiles, as well as a water heater replacement in 2015, though this permit has since expired. A violation was recorded in 2003 regarding unpermitted bathroom remodeling and sheetrock work, though this complaint is now inactive.

Recent maintenance issues in the vicinity of the property have primarily involved street lighting, with multiple reports of burnt-out streetlights in the summer and fall of 2020, all of which were promptly resolved by PG&E. The building's immediate surroundings have experienced minimal complaint activity, with only two incidents in 2021-2024 that directly affected residents: a parking enforcement issue for sidewalk parking in January 2021 (which was resolved by responding officers) and an open noise complaint filed in August 2024. Historical street maintenance issues have been addressed promptly, as evidenced by the 2018 general cleaning incident and a service request that was unable to be processed due to insufficient information.

Risk rating

How 21 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
