Initial analysis

The property at 342-348 Vallejo Street is a two-story, multi-family residential building constructed in 1910 in Telegraph Hill, containing 4 units and currently under the 1981 John E Wai Living Trust. The building has undergone significant recent renovations, with the most substantial work occurring between 2018-2024, including comprehensive unit remodels with kitchen renovations, bathroom additions, bedroom reconfigurations, and the installation of fire sprinklers. A major phase of the renovation work involving all four units resulted in the removal of finishes, electrical, and plumbing systems, leaving only exposed framing, which led to multiple building complaints in August 2020. These complaints also prompted concerns about unpermitted excavation and construction debris management.

Recent building improvements include the installation of fire safety systems, with permits issued in 2021 for comprehensive fire sprinkler work. The property has experienced some municipal compliance issues, with historical building violations in 2005 related to fire safety equipment, stairs, and emergency egress, though these were resolved within two months. Planning records indicate that the building underwent a substantial interior remodel without changing the unit count, including minor lightwell modifications to match neighboring configurations. A previously filed permit for excavation work in 2020 raised compliance concerns, though subsequent permits have addressed these issues. The building's recent renovation history shows significant investment in upgrading and modernizing the property, with permits totaling over $200,000 in value for various improvements between 2021-2024.

Risk rating

How 342-348 Vallejo 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.
