How Long Does It Take to Build a Pool?
A realistic week-by-week timeline for a custom pool build — including the permitting stretch most homeowners don't plan for.
The short answer: about four to seven months from your first conversation to your first swim. The construction itself is only eight to twelve weeks of that. The rest is design, proposal, engineering, and permitting — and permitting is the phase that surprises people.
Below is how that time actually distributes, and which parts of it you can influence.
The timeline at a glance
Ranges reflect real variation across the cities we serve. Elk Grove, Sacramento County, Folsom, Roseville, and El Dorado County all run their plan checks differently.
| Phase | Typical duration | Can you speed it up? |
|---|---|---|
| Consultation & 3D design | 1–2 weeks | Yes — decisiveness helps enormously |
| Proposal & agreement | 3–7 days | Yes |
| Engineering & permitting | 3–8 weeks | Rarely — this is jurisdiction-dependent |
| Layout & excavation | 2–4 days | No |
| Steel, plumbing, electrical | 1–2 weeks | No — inspections gate this |
| Gunite + cure | 1 day + 7–10 days | No |
| Tile, coping & decking | 2–3 weeks | Partly — pick materials early |
| Plaster, fill & startup | 3–5 days | No |
| Landscape & handoff | 1–3 weeks | Yes — or defer to a later phase |
Why permitting takes as long as it does
A swimming pool is a permitted structure. Plans have to be engineered for your soil and grade, submitted to your city or county, reviewed by a plan checker, corrected if the reviewer has comments, and then approved before a shovel touches the ground.
Plan-check queues fluctuate with building activity. In a busy season a first review can take four to six weeks, and any correction cycle adds to that. We submit complete, engineered packages specifically to minimize correction rounds, but we cannot control the queue itself. Anyone who promises you a guaranteed permit date is guessing.
What actually delays projects
In our experience, the schedule slips for a small number of recurring reasons — and most of them are avoidable.
- Late material selections. Tile, coping, and deck finishes need to be locked before the decking phase. Undecided selections stall a crew that's ready to work.
- Design changes after permitting. Changing the shape after plans are approved means re-engineering and re-submitting.
- Weather. Gunite and concrete can't be placed in heavy rain, and saturated soil stops excavation. Winter builds carry more weather risk.
- Inspection scheduling. Departments schedule inspections on their own calendars, and a missed window can cost several days.
- Access problems. Discovering on dig day that the gate is too narrow for the excavator is a schedule event, which is why we check access at the very first visit.
The best time of year to start
If you want to swim next summer, start the conversation in the fall or early winter. Design and permitting happen during the months you wouldn't be swimming anyway, construction runs through spring, and the pool is ready when the weather turns.
Homeowners who call in May hoping to swim in July are almost always disappointed, not because of construction speed but because permitting doesn't compress. Starting early is the single most effective thing you can do to control your timeline.
