Initial analysis

The property at 536-538 28th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1908 and currently owned by Yee Kam Yuen, the building underwent significant renovations in 2007-2008, including the installation of a comprehensive fire sprinkler system ($16,000) and major plumbing work to accommodate three units with seven bathrooms, three kitchens, furnaces, water heaters, and laundry facilities ($10,000). During this renovation period, the building's electrical infrastructure was also upgraded with 80 lights, 95 switches, and four 120-amp panels. A notable change was the revision to relocate bathrooms, modify walls and doors, and combine two front decks at the third floor, along with the addition of a decorative fireplace.

More recent history includes a fire sprinkler head relocation project in 2018 and a fire-related incident in June 2023 that was determined to have no merit. The building has experienced some parking-related issues in the vicinity, with multiple citations issued between 2020 and 2022 for various parking violations, though these are not directly related to the building's condition or management. There was one housing inspection complaint filed in 2010 that was resolved within a month. Planning records show previous proposals for larger development projects at this location, including plans for a new three-family, four-story building and a horizontal rear addition, but these were withdrawn or closed without action. The most recent permit activity involves a revision to legalize a portion of the roof deck, which was approved in 2023. The building's current condition appears stable, with no active building code violations or pending permits needing attention as of October 2023.

Risk rating

How 536-538 28Th 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, 1012 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.

Neighborhood location

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

Building age

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

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 72.7%
Moderate concern 22.6%
Severe concern 4.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
