Initial analysis

The two-unit residential property at 1 Mayfair Drive in the Jordan Park/Laurel Heights neighborhood is a two-story flats and duplex building constructed in 1951, currently owned by the Lawrence & Esther Lai Revoc Trust. The building's maintenance history shows attention to structural issues, with dry rot repairs completed in 2009 at the front corner windows and walls, including work on oak flooring on the second floor, and a reroofing project permitted in 2006 costing $11,000. A recent electrical survey was issued in April 2022, indicating ongoing infrastructure attention.

The property has experienced several incidents over the past two years, primarily related to graffiti and abandoned vehicles in the vicinity. Between 2022 and 2024, there were multiple reports of graffiti on and around the building, particularly in 2022 when the property was affected by a backlog of complaints resulting from suspended enforcement of the San Francisco Graffiti Ordinance during the COVID pandemic. More recently, in early 2023, there was one instance of graffiti reported as "offensive" on or near the building. The area around the building has also seen five reports of abandoned vehicles between 2023 and 2024, with two of these incidents resulting in vehicle towings and one involving a pickup truck that was gone upon inspection. Two encampment reports were filed in November 2022, though officials were unable to locate the sites in both instances. It's worth noting that there have been two fire alarm incidents recorded, both unintentional activations with no civilian injuries reported.

Risk rating

How 1 Mayfair Dr'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 272 buildings in this neighborhood, 65 are predicted to be safer.
