Initial analysis

The 6-unit, 3-story apartment building at 3481 Pierce Street in the Marina neighborhood, owned by John Strain Family Partners, has undergone several significant safety and infrastructure improvements since its construction in 1926. Most notably, the building completed its mandatory soft-story retrofit in 2019 (Tier 4) at a cost of $120,000, bringing it into compliance with San Francisco's earthquake safety requirements. Recent work includes a $20,482 fire alarm system upgrade initiated in March 2024 to meet the 2016 SFFC requirements, with an electrical permit for the same work issued in October 2024. The building's electrical systems have seen substantial modernization, including a new 200-amp service installation with seven meters and panels in 2006, and garage electrical work in 2009.

The property has experienced a number of safety violations over the years, particularly in 2001 and 2007, including issues with egress obstructions, fire escape maintenance, smoke detector functionality, and deadlocked exit doors. These violations were all officially abated by July 2007. More recent history shows persistent issues with driveway blocking, with numerous parking enforcement calls between December 2023 and May 2025, though these are not building safety concerns. The building's maintenance record shows attention to roof maintenance in 1999, and various other improvements, suggesting ongoing property upkeep by ownership.

Risk rating

How 3481 Pierce St'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
31th percentile

Out of 988 buildings in this neighborhood, 682 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

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 50.6%
Moderate concern 18.9%
Severe concern 30.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
