Initial analysis

The 3-unit multi-family residential building at 518-520 Baker Street, located in Park North and owned by Winston L. Wolff and Step Tang, is undergoing significant renovations and upgrades following a major permitted project in 2021 that added a new unit on the ground floor and remodeled the second and third floors at a cost of $750,000. The property, built in 1927, is currently receiving extensive updates including the installation of a new fire sprinkler system throughout the ground floor (2024), comprehensive plumbing improvements with three new tankless water heaters and radiant heating (2024), and electrical upgrades including new wiring, sub-panels, and solar panel installation (2024). Recent safety improvements include the addition of fire-rated entrance doors and modifications to unit entrance doors (2024).

The building's renovation timeline reveals careful attention to modern safety standards and sustainable features, with permits showing the installation of new utilities infrastructure including water service, gas lines, and electrical systems to accommodate contemporary living requirements. Historical maintenance records from 2018 show previous bathroom remodeling work, and multiple permits indicate systematic updates to the building's infrastructure, including seismic improvements and new utility systems. The property has experienced typical urban issues as documented in 311 calls, primarily related to street cleaning and maintenance matters, though none directly impact the building's structural or safety systems.

Risk rating

How 518-520 Baker St'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.
