An owner-builder is someone who owns property and takes the lead on a construction project. They perform the role of the general contractor and oversee the work of general contractors. You do not need any construction experience to be an owner-builder!
Successful owner-builders have strong organizational and communication skills. They have to hire subcontractors, take care of any legalities like permits and HOA approvals, schedule the work, balance budgets, and handle any issues that arise. The buck stops with you!
