Initial analysis

The three-story, 6-unit multi-family residential building at 679 48th Avenue in the Outer Richmond, built in 1960 and currently owned by the Marylyn L Saucer 1988 Trust, has undergone several significant repairs and improvements over recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $52,600, demonstrating compliance with seismic safety requirements. Recent maintenance includes the replacement of damaged deck boards in 2024 ($3,000) and historical repairs to rear stairs in 2016 ($10,000). The building has also seen important infrastructure upgrades, including a water main line replacement in 2019, sewer repair in 2012, and electrical system improvements in 2008 with a 200-amp meter and sub-panel relocation.

The property has experienced some notable issues over its history, particularly regarding water management. In 2014, there was a significant incident involving water overflow from the parking lot and retaining wall that affected multiple properties, though this was addressed promptly. Historical violations (now resolved) from 2006 included multiple building and fire safety concerns such as deck repairs, smoke enclosure door issues, and egress obstructions. The building's maintenance history shows regular attention to safety systems, though there were some instances of combustible materials noted by fire inspectors in 2013 and 2014, which were promptly corrected. Recent 311 calls for the area primarily relate to external matters such as encampments and street maintenance, with no recent building-specific complaints or violations on record. The building's documented history shows ongoing maintenance and compliance with safety regulations, with no active violations or unresolved complaints as of 2023.

Risk rating

How 679 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 1040 buildings in this neighborhood, 884 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.

Neighborhood location

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

Number of units

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 53.5%
Moderate concern 20.8%
Severe concern 25.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
