Should you DIY a whole-house repiping in Los Angeles?

Whole-House Repiping isn't a realistic DIY project for most homeowners — it typically requires licensing, permitting, and specialized equipment that make self-performing the work impractical or unsafe. In Los Angeles, a permit and inspection are required for this work, which most jurisdictions restrict to licensed contractors. Treat the contractor's labor line item as a fixed cost rather than a place to look for savings.
