Initial analysis

The four-unit, two-story multi-family residential building at 1901 Pierce Street in Lower Pacific Heights, owned by the Western Dominican Province, was constructed in 1900 and has undergone several significant maintenance and safety-related improvements over the years. Most recently, in 2020, the building received a roof replacement with modified bitumen materials at a cost of $10,000. The property has experienced multiple fire safety incidents, including smoke detector activations and two unintentional fires, though fortunately without civilian injuries. A notable series of violations was recorded in 2004 related to fire safety and security, including issues with fire proofing, smoke enclosure doors, combustible storage, and security locks, all of which were abated by July 2004. In 2010, there was a complaint regarding unauthorized work and the demolition of exterior decks on the east side of the building, though this was subsequently addressed.

The building's infrastructure has seen several important upgrades, including a complete sewer line replacement from the garage to the house trap in 2018, and extensive electrical work in 2003 installing various lighting and electrical components. Recent activity shows ongoing maintenance concerns, with multiple 311 calls in late 2024 regarding garbage and debris removal, including several reports about abandoned Christmas trees and other waste. The property has had routine housing inspections in 1996, 1999, and 2004, showing regular oversight of building conditions. A sidewalk defect related to tree root lifting was reported in November 2024 and remains open as of the latest update. While the building has experienced various safety system activations, including smoke detector and alarm system activations, these incidents have generally been unintentional or due to system malfunction, with no reported civilian injuries from any fire-related incidents.

Risk rating

How 1901 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
43th percentile

Out of 670 buildings in this neighborhood, 382 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 age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 76.8%
Moderate concern 12.9%
Severe concern 10.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
