Initial analysis

The two-unit residential building at 266-268 25th Avenue, owned by Wong Kwok Koi & Tak Nui, is a 2-story flats and duplex structure built in 1911 in the Lake—The Presidio neighborhood. The building's maintenance record shows several permit activities, including two sidewalk permits issued in April 2007, though these were at no cost, and a significant window replacement project completed in 2002 costing $15,000, which involved replacing 20 aluminum windows with vinyl ones visible from the street.

The property has generated a number of 311 calls over the past few years, with the most recent being a Rent Board-related inquiry in January 2025 that was resolved with the caller confirming they had a Home Ownership Equity (HOE) on file. There were two incidents of driveway blockage in 2023 (November and July), both of which were resolved with citations being issued. Other notable incidents include reports of human/animal waste in September 2023 (which inspectors were unable to verify), a graffiti incident in 2022 that was promptly addressed, and two open/closed park-related maintenance issues from 2021 involving recreation equipment. The building's documented history shows regular maintenance and some community-related issues, primarily concerning adjacent street and park areas rather than the building itself.

Risk rating

How 266-268 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
44th percentile

Out of 660 buildings in this neighborhood, 370 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 70.9%
Moderate concern 24.1%
Severe concern 5.0%
