Electrical: Capacity, Safety, and Lighting Quality
Start with a load calc and panel review—attic suites often need new AFCI-protected circuits, dedicated HVAC power, and low-voltage for data. Map receptacles per code, add USB-C outlets in niches, and use high-CRI LED layers with smart dimmers. Maintain clear cable paths in shallow rafters and specify IC/AT fixtures to protect the air barrier.
Plumbing: Short, Insulated Runs
For a bath or wet bar, minimize run lengths and pumping head. Use 3/8–1/2 inch insulated PEX home runs, heat-trace where cold exposure is possible, and vent properly to avoid slow drains. Plan an accessible shutoff and a sloped, fully lined shower with robust waterproofing. Coordinate exhaust fans ducted outdoors to prevent moisture looping into soffits.
Integration & Inspections
Sequence rough-ins before insulation, label circuits and valves, and photograph walls for future service. NYC inspections typically cover rough MEP and final; keeping a clean submittal log avoids rework. For scope overviews and coordination tips, visit attic plumbing and electrical upgrades in NYC.
