Initial analysis

The three-story, 30-unit apartment building at 3445-3455 Pierce St, owned by Blaine 1977 Revoc Tr and located in the Marina neighborhood, was constructed in 1927 and is classified as a Multi-Family Residential building with 15 or more units. The property has undergone significant safety and modernization upgrades in recent years, most notably a comprehensive fire life safety system upgrade in 2022 costing $45,000, which included the installation of low frequency horns and a new fire panel. The building has a completed Soft Story retrofit under Tier 4 requirements, demonstrating compliance with seismic safety standards. Between 2017 and 2020, multiple unit renovations were completed, including kitchen and bathroom remodels in units 104, 105, 202, and general building improvements such as the replacement of boilers and water heaters, electrical system updates, and plumbing upgrades.

The property has experienced several fire safety-related incidents and complaints, mostly involving alarm system activations, smoke detector malfunctions, and false alarms, though most were determined to have no merit or were promptly corrected. Historical records from 2000 show temperature control and egress obstruction issues that were resolved, and there was a boiler operation permit violation from 2020 that appears to have been addressed. Recent maintenance and service requests from 2023-2025 show typical urban dwelling issues, primarily related to parking enforcement and street cleaning matters. While there have been periodic fire alarm issues, the building's recent safety upgrades and prompt response to maintenance concerns suggest active management of resident safety and comfort.

Risk rating

How 3445-3455 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
9th percentile

Out of 988 buildings in this neighborhood, 899 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.

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 33.4%
Moderate concern 43.7%
Severe concern 23.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
