Process overview

The swimlanes in the original map represent the delivery clock, not the Census statistical clock. Both matter, but they answer different questions.

New construction: two delivery models

• Built for sale - production: default lens because built-for-sale dominates current starts.
• Custom - owner’s land: alternate lane because owner-controlled land and owner-led decision-making change the process shape.

Renovation: two project types

• Major renovation - addition: whole-house gut renovations, large-scale remodels with structural changes, and room additions. Architect-led or design-build, fully permitted. Concealed conditions are the signature risk.
• Targeted renovation: kitchen remodels, bathroom remodels, and systems replacements. Compressed timeline, often contractor-led or design-build, product lead times drive the schedule.

Important distinction

The Census clock is best for market statistics. The delivery clock is best for understanding who decides what, which documents move when, and where friction accumulates. Renovation projects follow the delivery clock but not the Census statistical clock (renovation is tracked by AHS and JCHS LIRA, not the Survey of Construction).
