Initial analysis

The property at 145-147 Jersey Street in Noe Valley is a 2-story, 4-unit multi-family residential building constructed in 1908, currently owned by the Gianaras Living Trust. The building has undergone several significant renovations over the past two decades, with the most recent major work being a $14,000 reroofing project completed in 2022. Earlier improvements include comprehensive kitchen and bathroom remodels in 2006-2010, including modernizations to plumbing and electrical systems, and roof maintenance. The building's infrastructure has required attention to sewer systems, including a complete sewer line replacement from the house to the street in 2012, though there have been recurring sewer-related issues, with multiple reports of sewage backups and flooding incidents recorded in 2022, and a more recent backup incident in January 2025 from a side sewer vent.

The property's maintenance history shows regular upkeep with several street space permits issued between 2008-2014, and electrical system upgrades including new circuits, lighting, and appliance installations during renovation periods. A concerning historical complaint from 1996 reported improper use of storage space as a woodworking area, though this was promptly addressed the following day. More recently, there have been recurring issues in the immediate vicinity of the building, including encampments (2024), parking violations, and a curb defect (2023), though these are external to the building itself. The property's maintenance record demonstrates ongoing investment in improvements and repairs, particularly focusing on modernizing individual units and maintaining building systems, though the recurring sewer issues suggest this infrastructure requires continued monitoring.

Risk rating

How 145-147 Jersey 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.

Neighborhood percentile
