Initial analysis

The three-unit multi-family residential building at 56 Pierce Street, located in Hayes Valley and owned by the Wilson Family Revocable Trust, has a documented history spanning several decades. The three-story flats and duplex structure was built in 1903 and has undergone some regulatory scrutiny over the years. Notably, in 2002, the property received citations for fire safety and security violations, specifically regarding fire extinguisher maintenance and security requirements, though these violations were resolved within two months of being issued. A completed building permit from 1986 indicates work was done to bring the property into code compliance, and a routine housing inspection in 2008 also occurred without any noted ongoing issues.

Recent activity around the property has primarily involved external maintenance matters, with multiple 311 calls in 2024 related to parking violations on nearby sidewalks and street cleaning issues. The most recent call was regarding an abandoned Christmas tree in January 2025. The building's records also show engagement with the Mills Act program, with two applications processed and one approved under the name of Adam Wilson, though specific details about the nature of the Mills Act application and its implications for the property are not provided in the available data. While the building's historical records show periods of regulatory attention, particularly in the early 2000s, there have been no recent building violations or complaints recorded in several years, suggesting improved compliance with housing codes and regulations.

Risk rating

How 56 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

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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 48.4%
Moderate concern 19.6%
Severe concern 31.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
