Initial analysis

The property at 779-781 Chestnut Street in Russian Hill is a two-unit, two-story multi-family residence known as a Flats & Duplex, constructed in 1912 and currently owned by the Guido & Jean Ghiglieri Revocable Trust. The building has undergone several significant improvements over the past decade, most notably in 2014 when it received an electrical system upgrade to 200-amp service with two meters and panelboards, along with the installation of 18 new windows (6 Anderson Fibrex windows in the front and 12 vinyl windows in the rear) at a cost of $10,100. A complete reroofing project was successfully finished in 2009, costing $6,850. Two permits for "street space" were issued in September 2015, though the specific purpose was not detailed.

The building's maintenance record shows relatively few resident-impacting issues, with the most recent concern being a missing side sewer vent cover reported in March 2021, which was resolved. While there were multiple reports of street cleaning issues between 2018-2021, including general cleaning and graffiti, these incidents were addressed through normal city operations and did not directly involve the building's infrastructure. The property experienced three instances of abandoned vehicles on the adjacent street between 2013-2018, none of which were directly related to the building's operation or maintenance. Historical records show consistent property improvements, particularly in 2014 when major upgrades to both windows and electrical systems were completed, suggesting proactive maintenance by the current owners.

Risk rating

How 779-781 Chestnut 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.
