For a custom home, plan on 12 to 24 months from first drawing to move-in. Roughly a third of that is design, engineering, and permitting, before anyone breaks ground. Production builders in a subdivision move faster. A custom home on mountain land moves slower, and the site is usually the reason.
The honest answer to how long does it take to build a house is that the clock starts long before construction. Most people ask the question with only the construction phase in mind, then are surprised by the eight months in front of it.
Key Takeaways
- Design and engineering: roughly 2 to 5 months for a custom home.
- Permitting: 1 to 3 months, entirely dependent on your county.
- Construction: 7 to 14 months for a custom build on a normal site.
- Mountain weather can close the build window for months and push a start into the following spring.
- The site drives the schedule more than the square footage does.

How Long Does It Take to Build a House, Phase by Phase
| Phase | Typical duration | What controls it |
|---|---|---|
| Site and land review | 2 to 6 weeks | Access, survey availability, soils testing |
| Design and floor plan | 6 to 14 weeks | How many revisions you want, decision speed |
| Structural engineering | 3 to 6 weeks | Snow and wind loads, complexity of the structure |
| Permitting and county review | 4 to 12 weeks | Which county, WUI review, septic approval |
| Site work and foundation | 3 to 8 weeks | Grade, rock, weather, access for equipment |
| Shell and dry-in | 8 to 16 weeks | Structure type, crane access, material lead times |
| Mechanical, interior, finish | 16 to 28 weeks | Selections, trade availability, custom millwork |
| Final inspection and closeout | 2 to 4 weeks | Inspector scheduling, punch list |
Phases overlap. Engineering runs alongside late design, and finish trades stack once the building is dry. That is why the phases above add to more than the 12 to 24 month range.
Why Design Drives How Long It Takes to Build a House
When people ask how long does it take to build a house, they are usually picturing framing crews. The slower part is upstream.
A custom home is drawn around a specific piece of ground. That means the survey, the soils, the access, and the setbacks all have to be understood before the floor plan is final. Every revision you request adds time, and so does every week a decision sits unmade. Clients who decide quickly finish design in eight weeks. Clients who keep reopening the plan take five months.
Structural engineering follows design, not the other way around. On a log or timber structure the engineer also has to account for settling, which is a detail conventional framing does not carry. See our page on how we design custom log homes around your land.
Permitting: The Phase You Cannot Speed Up
Nothing changes how long does it take to build a house more predictably than a county review queue.
County review is the one phase where hustle does not help. Submit a complete set and it moves. Submit an incomplete one and you go to the back of the queue.
In Colorado mountain counties, three things commonly extend review: septic permitting through the health department, wildland-urban interface requirements on materials and defensible space, and access-width rules for fire apparatus. Any one of them can add weeks. Our guide to navigating building codes covers what a complete submittal looks like.
What the Site Adds to the Schedule
Ask how long does it take to build a house and the honest reply is another question: on what ground? Two identical houses on two different parcels will not take the same amount of time. The site decides more of the schedule than the design does.
- Access. If a loaded concrete truck cannot reach the pad, material gets shuttled in smaller loads. That slows every delivery for the entire build.
- Grade. Steep ground means more excavation, retaining, and engineered foundation work before anything vertical happens.
- Rock. Shallow bedrock turns a two-week excavation into a six-week one.
- Utilities. A long power line extension has its own lead time, set by the utility, not by you.
- Weather. You cannot pour concrete or set logs through a hard freeze. At elevation that can close the site for months.
This is why we look at parcels with clients before they buy. See our checklist on what to check when buying land to build a house.
How Long Does It Take to Build a House by Build Type
| Path | Typical total | Trade-off |
|---|---|---|
| Production home in a subdivision | 6 to 10 months | Fixed plans, prepped lot, no site surprises |
| Log or timber kit on a prepared site | 9 to 16 months | Shell arrives ready; you still permit, foundation, and finish |
| Custom home on ordinary ground | 12 to 20 months | Plan drawn to you, more decisions, more time |
| Custom home on a difficult mountain site | 16 to 24+ months | Access, grade, and weather set the pace |
The U.S. Census Bureau Survey of Construction tracks average completion times nationally, and consistently shows owner-built and contractor-built homes taking substantially longer than production builds. Mountain sites sit at the long end of that distribution.
Five Things That Actually Shorten the Timeline
You cannot change the weather, but several of the inputs to how long does it take to build a house are entirely within your control.
- Decide fast during design. This is the single largest variable you personally control.
- Make selections early. Windows, doors, and custom millwork carry lead times measured in months. Choosing them late stops the job.
- Submit a complete permit set. One resubmittal can cost more time than the entire engineering phase.
- Start design in fall. If you want to build next season, the drawings and permits should be finished before the ground thaws.
- Use one accountable contractor. Handoffs between separate designers, engineers, and builders create gaps where the schedule quietly leaks.
The Question Behind the Question
Most people asking how long does it take to build a house are really asking when they can move in, and whether the answer is close enough to justify starting. It usually is, provided the design phase begins before the season you want to build.
The families who end up disappointed are almost always the ones who bought land in June and expected to be in by Christmas. The ones who are happy started drawing the previous fall.
Frequently Asked Questions
How long does it take to build a house from start to finish?
For a custom home, 12 to 24 months from first drawing to move-in. Design and engineering take 2 to 5 months, permitting 1 to 3 months, and construction 7 to 14 months. Production homes in a subdivision are faster because the lot is prepped and the plans are fixed.
How long does the design phase take?
Six to fourteen weeks for most custom homes, plus three to six weeks of structural engineering. Clients who make decisions quickly finish in about eight weeks. Repeated changes to the floor plan are the most common reason design runs long.
Does building on a mountain site take longer?
Yes. Access, grade, shallow rock, and weather all extend the schedule, and at elevation you cannot pour concrete or set logs through a hard freeze. A difficult site can add six months or more compared with flat, serviced ground.
Can I speed up permitting?
Not really, but you can avoid slowing it down. Submitting a complete set the first time is the difference between a few weeks and a few months. Septic approval and wildfire interface review are the two items that most often add time in Colorado mountain counties.
When should I start if I want to build next summer?
Start design in the fall. Drawings, engineering, and permits should be finished before the ground thaws so construction can begin the moment the site opens.
Is a log home slower to build than a conventional house?
Not dramatically, but it is different. Log and timber structures need engineering for settling and often need crane access, and material lead times can be longer. The site usually affects the schedule more than the structure type does.
Start the Clock Where It Actually Starts
If you are weighing how long does it take to build a house against the season you want to move in, the answer starts with the parcel.
