Initial analysis

The 12-unit, 3-story multi-family residential building at 3366 Pierce Street in the Marina district was constructed in 1927 and is currently owned by Gruham LLC. The building has undergone several significant safety and infrastructure upgrades in recent years. Most notably, it completed a mandatory soft story seismic retrofit in 2017 (Tier 3) at a cost of $110,000, followed by low-frequency sounder installations and fire alarm system upgrades in 2021/2022 to enhance fire safety. Other major improvements include a staircase replacement for emergency egress in 2015 ($16,000), a comprehensive window replacement project in 2008 ($39,500), and an electrical service upgrade in 2004.

The building's maintenance history shows attention to safety compliance, with previous violations in 2001-2007 related to boiler permits and fire extinguisher maintenance that were all properly resolved. There have been two smoke detector activations with no fires recorded in the fire incident history. Recent 311 calls primarily relate to parking enforcement issues, with multiple reports of blocked driveways between 2021 and 2025, as well as some incidents of sidewalk cleaning needs in 2021. A fire complaint regarding blocked exits in 2020 was found to have "No Merit," and a staircase replacement project was completed to address egress requirements. The building appears to have maintained compliance with safety regulations, particularly through its recent seismic retrofitting and fire safety system upgrades.

Risk rating

How 3366 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, 751 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 47.0%
Moderate concern 31.5%
Severe concern 21.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
