Initial analysis

The 8-unit multi-family residential building at 1436 48th Avenue in San Francisco's Outer Sunset neighborhood was constructed in 1975 and is administered by Decedents Tr - Wong 90 Trus. The property has undergone several significant maintenance and safety improvements over the years, most notably completing a mandatory soft-story retrofit in 2017 at a cost of $85,000, demonstrating compliance with seismic safety requirements. Historical records show two roofing projects: one completed in 1992 and another in 2005, though there was a complaint in 2016 regarding unpermitted re-roofing work.

The building has faced various maintenance and safety challenges, particularly between 2002-2013, including multiple fire safety violations in 2002 related to garage fire proofing, gas utility requirements, and combustible storage issues, all of which were resolved by November 2002. The property experienced water-related problems in 2010-2013, with complaints about window leaks, water damage, and mold, though these issues were eventually addressed. The building's recent history shows persistent parking-related concerns in the surrounding area, with multiple complaints about blocked driveways and sidewalk parking between 2022-2024, though these are external to the building itself.

Risk rating

How 1436 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, 581 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.

Building size

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

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.

12-Month severity forecast
No violation 19.2%
Moderate concern 20.4%
Severe concern 60.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
