Initial analysis

The building at 3440 Pierce Street is a two-story, five-unit multi-family residential structure built in 1927, currently owned by Bypass Tr-delmon Fmly Tr 20. The property has undergone several significant safety and infrastructure improvements over the past decade, most notably a weak story seismic retrofit in 2016 that included the installation of steel moment resisting frames and foundations ($25,000), and a mandatory fire alarm upgrade in 2023 to comply with California state fire marshal code. Recent maintenance includes a gas line repair for the stove in July 2023, and the building's fire safety systems have experienced multiple false alarms, though no actual fires have been recorded.

The building's infrastructure has received consistent attention, with major works including reroofing in 2015 ($11,000), water main replacement in 2013, and various plumbing upgrades. However, it's important to note that the building is currently listed as non-compliant with tier 4 soft story requirements, indicating that while many structural improvements have been made, there are still outstanding seismic retrofit obligations. Recent 311 calls show typical urban maintenance issues, including sidewalk defects (2024), animal waste (2024), and tree-related concerns, though most have been resolved promptly. The property has maintained basic habitability standards with no reported injuries from its recorded fire incidents, which have all involved system malfunctions or false alarms rather than actual fires.

Risk rating

How 3440 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

Out of 988 buildings in this neighborhood, 622 are predicted to be safer.

Model explanation

What's driving this score

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.

Owner's portfolio size

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

12-Month severity forecast
No violation 61.2%
Moderate concern 13.5%
Severe concern 25.3%
