Initial analysis

The two-unit residential building at 440-442 Vallejo Street in Telegraph Hill is a 2-story flats and duplex structure built in 1912, currently owned by Nancy L. Ruiz. The property has undergone significant renovations and improvements over the past decade, with substantial work performed in 2017-2018 including electrical upgrades (200-amp service installation, extensive wiring work for lights and plugs), plumbing improvements (tankless water heaters, bathroom remodels), and heating system modifications (radiant to forced air conversion). These upgrades were accompanied by multiple street space permits between 2016-2018, suggesting coordinated improvements requiring temporary street access.

The building had several violations in July 2014, primarily related to building maintenance issues such as window repairs, door bells, and thermostats, though all were resolved by August 2014. A complaint regarding mold/mildew was filed in 2014, and there was an investigation into possible unpermitted construction in August 2020, though this was marked as not active. Planning records reveal previous issues with illegal short-term rentals in 2016-2017, though these violations were abated. The most recent significant work on the property involved multiple plumbing and electrical permit renewals in 2019, ensuring completion of earlier improvements. The building's maintenance history shows regular upkeep and system upgrades, with all identified code violations being addressed within reasonable timeframes.

Risk rating

How 440-442 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.
