Initial analysis

The three-unit multi-family residential building at 1506-1510 Masonic Avenue, owned by Gregory Ishizaki Revocable Trust, has undergone significant renovations and improvements in recent years, particularly during 2022-2023. Built in 1904, this three-story structure has seen major upgrades including the installation of new furnaces and windows in multiple units, bathroom and kitchen remodels, and electrical system overhauls totaling approximately $150,000 in improvements. The 2022 renovation work focused primarily on the 2nd and 3rd floor units, involving comprehensive updates to kitchens, bathrooms, electrical systems, and the addition of laundry facilities. Safety enhancements included modifications to the fire sprinkler system and updates to comply with current building codes.

The building's maintenance history shows earlier concerns from 2003, including issues with fire escape obstructions, broken steps, and sanitation matters, all of which were resolved by April 2003. A notable complaint about paint preparation work and debris in 2012 was promptly addressed within days. More recent complaints have been limited to routine inspections, though there is currently an open noise complaint regarding mechanical equipment from May 2024. The property's maintenance record indicates regular upkeep, with no active violations or complaints currently on file. While there have been multiple parking enforcement calls in 2024, these are typical urban issues not directly related to the building's condition or management.

Risk rating

How 1506-1510 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
93th percentile

Out of 351 buildings in this neighborhood, 25 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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 81.0%
Moderate concern 15.8%
Severe concern 3.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
