Initial analysis

The two-unit residential building at 155 Masonic Avenue in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1939, currently owned by Lee Leslie and Diane H. The property has undergone several significant improvements in recent years, with the most recent work including a completed reroofing project in July 2024 costing $10,000, and a substantial renovation in May 2024 involving window replacement and siding improvements totaling $25,000. Prior to these, a bathroom remodel was successfully completed in 2022 with appropriate plumbing and electrical permits, while records show a previous reroofing project was initiated in 2019 at a cost of $3,500.

The building's recent history has included multiple maintenance and graffiti-related issues in 2024, with eight reported incidents of graffiti or street cleaning concerns between June and December 2024. These exterior maintenance challenges consisted primarily of non-offensive graffiti on various surfaces, including the building itself and nearby poles, with most cases being resolved through cleaning or painting by city services. Building services were generally responsive to complaints, as evidenced by resolved cases related to garbage and debris concerns. A parking enforcement incident occurred in July 2024 involving a blocked driveway, resulting in a citation. While there were no serious safety concerns reported, the frequency of exterior maintenance issues in 2024 suggests ongoing attention to the building's external environments may be needed.

Risk rating

How 155 Masonic 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 519 buildings in this neighborhood, 42 are predicted to be safer.

What's driving this score

12-Month severity forecast
No violation 89.7%
Moderate concern 8.5%
Severe concern 1.8%
