The 4-unit, 2-story multi-family residential building at 511 Fell Street in Hayes Valley, owned by Cc Family Trust, has undergone significant renovations and improvements over the past decade. The property, built in 1890, has seen substantial unit upgrades between 2013-2015, including comprehensive remodeling of Units #2 and #4 with bathroom and kitchen relocations, electrical upgrades, and lighting improvements. In 2023, a new sewer lateral was installed, representing the most recent infrastructure upgrade. The building's electrical system received considerable attention in 2010 with the installation of a new 200-amp service and four 60-amp subpanels, while 2013-2015 saw various plumbing improvements, including kitchen and bathroom remodels across multiple units.

The property has a history of maintenance issues and violations, particularly evident in earlier records from 2002-2004, which documented problems such as damaged walls, stairs requiring repair, and fire safety concerns regarding smoke detectors. However, all these historical violations have been marked as abated. More recent concerns include a 2015 complaint about rodents, cracked stairs, and water damage, and a 2013 inspection revealing ceiling holes, cracked windows, and bathroom mold issues. The building's maintenance history shows a pattern of active improvements and repairs, with multiple units receiving attention between 2013-2015, including the replacement of kitchen cabinets, bathroom fixtures, and addressing structural issues like dry rot on back stairs. Recent permits indicate ongoing infrastructure maintenance, including the 2023 sewer lateral replacement, suggesting proactive management of essential systems. The property has maintained a regular schedule of routine safety inspections, with the most recent occurring in 2019, indicating continued oversight of building conditions. While there have been numerous 311 calls regarding the street conditions around the building, these predominantly relate to public areas rather than the building itself.

Risk rating

How 511 Fell 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.
