Initial analysis

The 123-125 Masonic Avenue property is a two-unit multi-family residential building located in the Lone Mountain neighborhood. Built in 1939, this two-story flats/duplex structure underwent significant modernization in 2019, with two major sets of improvements completed in August and September of that year. These upgrades included comprehensive electrical system enhancements (100 amp panel upgrades, new circuits and receptacles), plumbing improvements (installation of new high-efficiency furnaces, water heaters, and associated ductwork), and gas line capacity increases, with a total estimated cost of $85,000. Earlier improvements dating back to 1988 included the installation of vinyl siding on the building's rear wall.

The property has experienced recurring issues with graffiti in recent years, with multiple incidents reported between 2023-2024, suggesting an ongoing challenge with vandalism in the vicinity. There have also been several reports of street and sidewalk cleanliness concerns, including various instances of garbage and debris, particularly in 2024. While these exterior maintenance issues are notable, they appear to be more related to the immediate neighborhood and public spaces rather than the building itself. The property's infrastructure upgrades in 2019 demonstrate a significant investment in modernizing the building's systems, including electrical, plumbing, and HVAC components, which are essential for maintaining resident comfort and safety.

Risk rating

How 123-125 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
94th percentile

Out of 519 buildings in this neighborhood, 31 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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Building age

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

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.

12-Month severity forecast
No violation 92.8%
Moderate concern 5.8%
Severe concern 1.4%
