Initial analysis

The 8-unit, 2-story multi-family residential building at 1380 48th Avenue in the Outer Sunset, owned by the Giosso Family Living Trust and constructed in 1975, has undergone several significant structural and safety improvements over the years. Most recently, in May 2024, the building received a comprehensive electrical upgrade with the replacement of the house sub-panel in the garage and individual sub-panels in all six units. The building completed its mandatory soft-story retrofit in 2016 at a cost of $45,000, demonstrating compliance with San Francisco's seismic safety requirements. There have been three documented reroofing projects: in 1989, 2012 ($13,000), and most recently in 2019 ($5,000).

The property has experienced several fire safety-related issues in the early 2000s, including multiple violations in August 2002 concerning combustible storage in the garage and egress obstructions, as well as issues with gas meter documentation and fire extinguisher maintenance. These violations were all abated by November 2002. Two complaints about unpermitted roofing work were filed in 2005 and 2017, though both cases are now inactive. A routine fire alarm systems inspection in July 2007 resulted in condition correction. The building's recent maintenance history shows no active safety violations or recurring maintenance issues. While there have been multiple parking-related complaints near the property between 2018 and 2024, these are external issues not directly related to the building's condition or safety.

Risk rating

How 1380 48Th 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 632 buildings in this neighborhood, 600 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 25.8%
Moderate concern 23.8%
Severe concern 50.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
