Initial analysis

The two-story, four-unit multi-family residential building at 526 25th Avenue in the Central Richmond neighborhood, currently owned by Lawrence & May-wa Wong Fmly, was constructed in 1972 and has undergone several significant maintenance and improvement projects over the past few decades. Most recently, the building received a new roof in March 2020, costing $9,800, following a window replacement project in 2017 where fiberglass Milgard windows were installed at a cost of $5,000. An earlier roof installation from 1996 is noted as having expired in the records.

The building has experienced some maintenance challenges, particularly in 2016 when there were documented water leak issues that required attention from the PUC Water department. A more serious fire safety concern was addressed in 2003 when violations were issued regarding combustible storage, though these were promptly abated within two months. Additional incidents include a graffiti case in 2011 that underwent post-abatement inspection, and a 2020 environmental health service request that was transferred to the Department of Public Health's Environmental Health Healthy Housing & Vector Control Program. While there was one recorded fire incident classified as "100 Fire, other" with unintentional ignition in the records, it is specified that there were no civilian injuries. The building's parking violations are managed through standard city processes, with the most recent documented call regarding illegal parking occurring in May 2021.

Risk rating

How 526 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
87th percentile

Out of 2250 buildings in this neighborhood, 292 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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 80.3%
Moderate concern 11.2%
Severe concern 8.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
