New Construction
How long does it take to build a house?
Construction is the predictable part. Everything before it is where schedules go to die.
A ground-up build runs in three phases: design and engineering, plan check and permitting, then construction. The middle one varies by jurisdiction more than anything else in the process, which is why we ask each city rather than quoting you a number we can't control.
The three phases
Design and engineering
Architect and structural engineer produce a full permit set including Title 24. This phase moves at the speed of your decisions — it is the one you control most directly, and the one most often extended by changing your mind late.
Plan check and permitting
The city reviews, returns corrections, and you resubmit. Rarely one round. This is the phase nobody controls and everybody underestimates, and it varies substantially between jurisdictions.
Construction
Site work and foundation, framing, roof and envelope, rough-in for all trades, inspections, insulation and drywall, then finishes and final inspection. The most predictable phase, because it is sequenced work with known dependencies.
Why we won't quote you a permit timeline up front
Plan-check duration is set by the jurisdiction, not by us. We ask the building department directly on every project rather than assuming, because guessing here is how a builder ends up explaining a slipped date they should never have given.
What genuinely delays a build
- Late decisions. Selections made during framing instead of before it. This is the most common cause and the most controllable.
- Change orders mid-build. Every change has a schedule cost as well as a price, and the schedule half is usually the expensive one.
- Inspection holds. Work stops until the inspector arrives and passes it. This is by design and it is not padding.
- Utility coordination. Service connections and upgrades run on the utility's timeline, not yours.
- Long-lead materials. Windows and certain finishes have to be ordered early or they become the critical path.
- Hidden conditions. Less common on new construction than on renovation, but site and soils surprises happen below grade.
What a realistic schedule looks like
One that names the phases, marks which dates depend on the city rather than on us, identifies the long-lead items early, and gets updated when something moves. A single confident completion date offered before plan check is a sales tool, not a schedule.
