Initial analysis

The two-unit residential building at 42 Lapidge Street in Mission Dolores, owned by Harriet Zhang, was constructed in 1993 following the demolition of a single-family dwelling in 1990. The two-story flats and duplex have undergone several notable improvements over the years, including significant interior modifications in 1999 when storage rooms were converted into living space with the addition of a powder room, and a bathroom enlargement from 25 to 39 square feet. The building's exterior has received attention through various maintenance work, including reroofing in 2012 and several structural improvements in 1992, such as bay window height modification and siding replacement.

The property has experienced recurring issues with sidewalk parking violations, particularly between 2019 and 2023, with at least five incidents resulting in citations, though some vehicles could not be located by enforcement officers. Additionally, there have been occasional sanitation concerns in the vicinity, with reports of human waste or debris logged with the city's 311 system occurring as recently as 2024. The building's permit history shows consistent maintenance and upgrading of the property facilities, with no recorded significant safety violations or structural concerns in the recent past. While the sidewalk parking and sanitation issues in the area are noteworthy, the building itself appears to be properly maintained according to available permit records.

Risk rating

How 42 Lapidge St'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.
