Initial analysis

Located at 457-459 25th Avenue in the Central Richmond neighborhood, this three-story multi-family residential building was constructed in 1903 and currently contains two units, owned by David W. Sullivan. The property has undergone several significant maintenance activities over the years, most notably a complete reroofing project in 2019 costing $15,800, marking the most recent major infrastructure upgrade. Historical records from 2003 indicate serious structural and maintenance concerns, including multiple housing code violations such as water damage, ceiling holes, structural issues with a back addition, floor damage, mold, and electrical problems with exposed wiring - all of which were supposed to be addressed but represent a concerning pattern of deferred maintenance that dates back over two decades. Earlier records show other maintenance issues including dry rot in the rear stairs (1990) and an expired reroofing permit from 1997.

More recent history from 2022 through 2024 shows numerous street cleaning and sanitation issues in the vicinity of the building, with multiple reports of garbage, debris, and an overflowing city garbage can that were all resolved by Recology or DPW. There was also a flooding incident reported on August 19, 2023, involving the street sewer system, though this was an infrastructure issue affecting the broader area rather than the building itself. The property appears to be located in an area that experiences regular street cleaning and waste management challenges, as evidenced by the frequency of sanitation-related complaints in the surrounding area, though these incidents generally relate to external conditions rather than direct building maintenance issues.

Risk rating

How 457-459 25Th Ave'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 2250 buildings in this neighborhood, 585 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.

Building age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 74.0%
Moderate concern 21.2%
Severe concern 4.9%
