Initial analysis

The two-unit multi-family residential building at 1518 48th Avenue in the Outer Sunset, owned by Edmund K & Eva H Wong since 1990, has experienced several significant maintenance and safety issues, particularly in recent months. As of November 2024, there are multiple active violations filed on November 13, 2024, including problems with electrical outlets, plumbing issues, a damaged sill, bathtub refinishing, weatherstripping, fire safety equipment (missing fire extinguisher, CO/smoke alarm affidavit), and a guardrail repair, all of which were documented in a single complaint (202430832). The property is currently undergoing electrical upgrades, with permits issued in December 2024 to relocate main panels for improved electrical infrastructure.

The building's history reveals persistent maintenance challenges, including a 2010 complaint about high humidity/moisture causing mold and unstrapped water heaters (subsequently resolved), and an unauthorized construction complaint in 2009. Earlier maintenance work included a complete re-roofing in 2000 (completed) and stair resupporting with new handrails work in 1986 (permit expired). Recent 311 calls from late 2024 indicate ongoing issues with debris management around the property, including reports of overflowing bins and garbage problems, though these are not directly related to building conditions. A single fire incident involving a flammable liquid spill was recorded, though no civilian injuries were reported.

Risk rating

How 1518 48Th 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 632 buildings in this neighborhood, 404 are predicted to be safer.
