Philadelphia-specific considerations
Philadelphia has a dense trades market shaped by the city's older housing stock. L&I permitting for older row homes frequently uncovers legacy electrical or plumbing that needs updating before a permit is finalized. Given the local climate — cold winters, humid summers — it's worth planning the schedule around that when timing this project.

A hybrid approach — self-performing demo and finish work while hiring out the specialized portion — can capture a meaningful share of the roughly 20% potential labor savings without taking on the riskiest part of the job.
