Initial analysis

The three-story multi-family residential building at 470-474 Vallejo Street in Telegraph Hill, owned by Christophe & Annabelle Bach, was constructed in 1910 and contains two units. The property has undergone several significant renovations and faced some notable issues over the years. In 2008-2009, there were substantial improvements including complete kitchen and bathroom remodels in both units, sewer line replacements, and electrical upgrades including a 400-amp service upgrade. However, during this period, there were serious construction safety violations related to unsafe excavation without proper shoring, which were ultimately resolved by December 2009. More recent developments include the installation of an EV charger in 2022 and some concerning complaints from 2022 and 2023 regarding unauthorized renovations and construction work. The August 2023 complaint alleges unpermitted kitchen and bathroom remodeling, window replacements, and exterior stairwell work being conducted by unauthorized contractors, with claims that the current owners (who reportedly live in El Dorado Hills) are attempting to establish residency for tax purposes prior to selling the property. Additionally, there has been a pattern of maintenance and cleanliness issues in the immediate vicinity, with multiple 311 calls regarding garbage, debris, and parking violations in the surrounding area between 2023 and 2025, though these are not directly related to the building's condition or management.

Risk rating

How 470-474 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.
