Initial analysis

The property at 102-116 Duncan Street is a 2-story, 5-unit multi-family residential building with ground-floor retail space, built in 1908 and owned by Kristopher M. Reddy. The building has undergone several significant maintenance and safety improvements in recent years, including a completed $14,000 reroofing project in late 2023, termite repairs in 2021, and various plumbing upgrades from 2018-2019 including sewer line repairs and water heater replacements. The property faced multiple building violations in May 2017 related to safety and maintenance issues, including problems with stairs, flooring, fire extinguishers, interior walls, light fixtures, smoke detectors, and plumbing, all of which were abated by July 2017.

Recent concerns have emerged regarding the commercial space's exterior appearance, with a complaint filed in August 2023 about unprofessional signage and unauthorized handyman advertisements. The building has a history of maintenance challenges, with past complaints documenting issues such as mold (2019), structural problems (2017), interior surface damage (2017), and various plumbing and electrical repairs. Accessibility improvements were addressed in 2023 with the installation of disabled assistance signage and step striping. The property has received routine inspections over the years, including a concerning period in 2012-2013 with multiple complaints about interior conditions, though many of these issues were eventually resolved. Recent utility upgrades include a 100-amp electrical service upgrade and garage improvements completed in 2016. While there have been some recent maintenance complaints regarding the surrounding area (primarily related to parking and debris), these appear to be more related to street conditions than the building itself.

Risk rating

How 102-116 Duncan St's risk score is calculated
