Construction Timeline Expectations

How long each phase typically takes, common delays, and how to track against your timeline.

Average Build Timeline

A typical custom home takes **12-18 months** to build. Owner-builders average **15.1 months** due to the learning curve and coordination challenges.

Phase Duration Estimates

| Phase | Typical Duration |
|-------|-----------------|
| Pre-Construction | 2-4 weeks |
| Foundation | 2-4 weeks |
| Framing | 4-8 weeks |
| MEP Rough-In | 3-6 weeks |
| Insulation & Drywall | 3-5 weeks |
| Exterior | 4-8 weeks |
| Interior Finishes | 6-12 weeks |
| Final | 2-4 weeks |

Common Delays

• **Weather** — Rain, extreme cold, and wind can halt work for days or weeks
• **Material delays** — Order specialty items (windows, cabinets, appliances) early
• **Inspection wait times** — Budget 1-2 weeks for each inspection
• **Subcontractor scheduling** — Good subs are busy; book them months in advance

> TIP: Add 20-30% buffer to every phase estimate. This is realistic, not pessimistic.
