Initial analysis

The two-unit residential building at 518 25th Avenue, located in the Central Richmond neighborhood, is a two-story flats and duplex structure built in 1915 and currently owned by the Wong Family Living Trust. The property has undergone significant recent improvements, with two major renovation projects completed between 2020 and 2021. The third-floor unit received a comprehensive update in 2020, including kitchen and bathroom remodeling, sheetrock replacement, insulation installation, and painting work, followed by the first-floor unit receiving similar improvements in 2021. This first-floor renovation included kitchen and bathroom remodeling, laundry room updates, and window replacements, along with associated electrical and plumbing upgrades such as the installation of new furnaces and electrical sub-panels. During 2021, the building's electrical system received a substantial upgrade with the installation of a 200 amp, 3-meter underground service system.

Recent maintenance and safety records show one fire-related incident involving smoke odor (though no civilian injuries were reported), and while there has been significant attention to building improvements, there are no recorded planning code complaints or building code violations. The property has experienced recurring issues with street cleaning, particularly related to overflowing city garbage cans, with multiple incidents reported throughout 2023-2024, though these are primarily external to the building itself. The street area around the property has also seen occasional parking enforcement responses and light maintenance calls. The building's recent renovations, including window replacements, electrical system upgrades, and HVAC improvements, suggest substantial investment in maintaining and upgrading the property's infrastructure, with all major permits showing as completed in official records.

Risk rating

How 518 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
98th percentile

Out of 2250 buildings in this neighborhood, 45 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.

Owner's portfolio size

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

Building permits (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.

12-Month severity forecast
No violation 90.8%
Moderate concern 7.1%
Severe concern 2.0%
