Initial analysis

The property at 239-241 Masonic Avenue in San Francisco's Lone Mountain neighborhood is a two-story multi-family residential building owned by the University of San Francisco, containing three units and dating back to 1940. The building has undergone several significant improvements over the past decades, including aluminum window installation in 1987, a complete reroofing in 2000 costing $13,750, and most recently, a shower valve replacement and shower enclosure update in 2022, suggesting regular maintenance of its facilities.

The immediate surroundings of the property have experienced a notable increase in maintenance issues over the past year, with a pattern of graffiti incidents and infrastructure damage reported between September 2024 and January 2025. The building's vicinity has seen recurring graffiti on public infrastructure, particularly on poles and mailboxes, with the most recent reports in January 2025, though many of these cases have been resolved through city services or transferred to the US Postal Service for appropriate action. There were also several instances of garbage and debris issues in late 2024, including an overflowing city garbage can and other waste problems, though these were eventually resolved. A notable infrastructure concern was addressed in November 2024 with the resolution of a fallen tree incident. It's important to note that the only recorded fire incident associated with the property was a false alarm or false call, with no civilian injuries reported.

Risk rating

How 239-241 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
36th percentile

Out of 519 buildings in this neighborhood, 332 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 72.7%
Moderate concern 21.1%
Severe concern 6.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
