Initial analysis

The three-story multi-family residential building at 1309-1313 Masonic Avenue in the Haight-Ashbury neighborhood, built in 1908, is a three-unit flats and duplex structure currently owned by a Revocable Trust. The property has undergone several significant improvements over the past decade, with the most recent major work being a $39,800 complete reroofing project undertaken in 2019. The building has seen multiple kitchen renovations between 2013 and 2017, including comprehensive remodels, electrical upgrades, and plumbing work to improve ventilation and compliance with modern standards. An electrical system upgrade was completed in 2014, including subpanel improvements and grounding upgrades.

The building has experienced some safety and maintenance challenges, particularly in 2003 when a series of fire safety violations were documented, including issues with combustible storage in the garage and rear yard, exterior stairs, and the need for safety equipment like fire extinguishers and gas shutoff tools. These violations were eventually abated by May 2003. More recent inspection records from 2017 show two violations related to fire extinguisher maintenance, though these were also resolved. The property has had three fire department responses for various incidents, including a cooking fire contained to a container, two alarm activations, and a carbon monoxide detector activation, none of which resulted in civilian injuries. Recent maintenance issues have been limited to typical urban challenges, as evidenced by 311 calls regarding street cleaning and sidewalk maintenance.

Risk rating

How 1309-1313 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 581 buildings in this neighborhood, 145 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building age

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

DBI complaint rate, owner's portfolio

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

12-Month severity forecast
No violation 56.9%
Moderate concern 25.1%
Severe concern 18.0%
