Build your own house — and save tens of thousands.
Owner-builders who stay organized save roughly 10–25% of project cost by skipping the GC markup (though lost contractor discounts and overruns can eat into that). The complete field guide — from a retired general contractor with 15+ years on the job.

Permitting is a state problem
$34 each
Every state writes its own owner-builder exemption, its own permit packet, and its own inspection order. The free state guide tells you the rules. The permit kit turns them into the paperwork — the exemption walkthrough, the application checklist, the inspection sequence, and the where-to-file directory, with the statute citations printed beside them.
Filled states have a kit. The rest are in production.
