Initial analysis

The three-story, four-unit multi-family residential building at 3705 25th Street in Noe Valley, owned by Frederick R. Hosking II, was constructed in 1924. The property has undergone several significant maintenance activities over the years, including a reroofing project in 2002 costing $11,200, and a street space permit issued in 2009. A notable cluster of violations was recorded in March 2009, primarily focusing on safety and maintenance issues, including fire escape maintenance, door closing mechanisms, and weather proofing. These violations also addressed concerns about lead paint hazards and egress obstructions. All of these violations were eventually abated by December 2011.

The building has been subject to routine inspections by Housing Inspection Services in 2001, 2009, and 2009, focusing on common areas and overall maintenance compliance. More recent history of the property, while showing numerous external maintenance cases in the surrounding area, particularly in 2023 and 2024, suggests typical urban environmental challenges. Between 2021 and 2024, there have been several street-related incidents recorded through 311 calls, including sidewalk blockages, street cleaning needs, and graffiti on public mailboxes. However, these external issues primarily reflect neighborhood conditions rather than specific building maintenance concerns.

Risk rating

How 3705 25Th 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.

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.

Building size

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

12-Month severity forecast
No violation 42.8%
Moderate concern 24.4%
Severe concern 32.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
