Initial analysis

The three-story, 9-unit multi-family residential building at 419 Pierce Street in Hayes Valley, owned by Plaza Group LLC, has undergone significant improvements and faced various compliance issues since its construction in 1900. Most notably, the building completed its mandatory Soft Story retrofit work in compliance with San Francisco Building Code requirements, achieving "Work Complete, CFC Issued" status as a Tier 3 building. The property has seen substantial modernization efforts in recent years, including the addition of an ADU in 2017-2019 (with associated fire sprinklers and alarm systems), a fire alarm system upgrade in 2019 to meet current fire safety standards, and a major electrical service upgrade from 200A to 400A in 2018.

The building's maintenance and safety record shows regular inspections and prompt responses to identified issues, with most recent fire-related complaints in 2021-2022 related to sprinkler systems and hazardous materials being resolved with "Condition Corrected" dispositions. Historical records indicate previous routine safety inspections in 1997, 2001, 2008, and 2009, all of which were properly addressed. While there were multiple Soft Story compliance-related complaints filed in 2017-2020, these were ultimately resolved through completed retrofitting work. The building's recent history shows active management and substantial investment in safety systems, with completed permits totaling over $180,000 for various improvements including seismic retrofitting, fire safety upgrades, and unit modifications.

Risk rating

How 419 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
23th percentile

Out of 1027 buildings in this neighborhood, 791 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 28.3%
Moderate concern 44.7%
Severe concern 27.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
