Structural ideas

These are the three mental shortcuts that make the rest of the map easier to navigate.

1. The “owner” changes meaning by delivery model

In a custom home, the human homeowner is usually the active owner from day one. In a built-for-sale project, the builder-developer often plays that role through land, design, permits, and early construction; the end buyer may join later through a sales contract and option selections.

2. Documents are the real handoff points

Needs become sketches; sketches become design development; that becomes construction documents; then permit sets, bid packages, subcontracts, RFIs, change orders, inspections, pay applications, waivers, and closeout records. Most delay and rework comes from document handoffs going fuzzy, late, or out of sync.

Evidence: S3, S4, S5, S7, S8, S9, S10

3. Residential is local by law, fragmented by workflow

Model codes are national, but adoption and amendment happen by jurisdiction. That means one homebuilding process exists in principle, but many local versions exist in practice. Permit portals, checklists, plan review comments, and inspection scheduling are typically local.
