Initial analysis

The property at 500-504 Fell Street is a two-story multi-family residential building with 4 units, constructed in 1885 and owned by the Sylvan R Corazzi Revocable Trust. The building has a significant history of telecommunications infrastructure, particularly relating to AT&T and Sprint equipment, with multiple modifications and removals of antennas, batteries, and equipment occurring from 2013 through 2023. Most recently, in April 2023, AT&T completed a $35,000 modification involving antenna and battery work, with additional related electrical work currently underway as of September 2023. The building underwent a voluntary accessibility improvement in 2022 for its ground floor commercial space, and a substantial unit renovation occurred in 2020 including kitchen and bathroom remodels, completed with both plumbing and electrical permits.

The property has maintained active compliance with housing regulations, with routine safety inspections conducted in 1999, 2007, 2011, and 2018. Several violations were noted during the 2011 inspection, including issues with electrical receptacles, fire escape ladders, and smoke detectors, but these were promptly abated by March 1, 2011. A 2013 plumbing installation of a grease trap for a ground floor business was completed, and the building's utility systems appear to be regularly maintained, with the most recent work involving battery replacements for telecommunications equipment. Recent activity at the property in late 2024 showed typical urban maintenance issues such as abandoned furniture and garbage debris, though these were promptly addressed by city services.

Risk rating

How 500-504 Fell St's risk score is calculated

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
