The Real Timeline: 4–6 Months, Permit to Swim
Homeowners are often surprised the biggest variable in a Los Angeles pool build isn't construction — it's permitting. Plan on 4–6 months total from signed contract to first swim, with permits typically taking 6–10 weeks on their own through LA County or LA City.
Stage-by-Stage Timeline
- Design and engineering (2–4 weeks): site survey, structural engineering for hillside or complex sites, plan drafting
- Permitting (6–10 weeks): plan check submission, corrections, and final approval through LADBS or LA County Building & Safety
- Excavation and steel (1–2 weeks): digging the shell and setting rebar per engineered spec
- Gunite/shotcrete (1 week, plus 28-day cure): shell is sprayed and left to cure before plaster
- Plumbing, electrical, and decking (2–4 weeks): equipment set, decking poured, tile and coping installed
- Interior finish and startup (1–2 weeks): plaster or pebble finish applied, pool filled, chemistry balanced over 28 days
What Extends the Timeline
- Hillside or slope sites requiring geotechnical reports and additional engineering review
- Permit corrections — plan check rejections add 2–4 weeks per revision cycle
- Homeowners association or coastal commission review, common in Malibu and Rancho Palos Verdes
- Custom features — raised spas, negative edges, and water features that require extra structural detail
- Weather delays during gunite and curing stages
What Actually Moves Fast
Once permits are in hand, physical construction moves quickly — excavation to gunite is typically 2–3 weeks. The 28-day plaster cure and chemistry balancing period is fixed regardless of contractor, so there's little to gain by rushing the finish stage.
💡 Pro Tip
Submit your permit application the same week you sign your contract — don't wait for final design sign-off on every finish detail. Cosmetic selections (tile pattern, coping color) can be finalized while plan check is in review.

Frequently Asked Questions
How long does it take to build a pool in LA?
Plan on 4–6 months total from signed contract to swim-ready, including 6–10 weeks for permits through LA County or LA City building departments.
What takes the longest in a pool build — permits or construction?
Permits usually take longer than the actual construction. Physical build time from excavation to plaster is often 6–8 weeks, while permitting alone can take 6–10 weeks.
Can I speed up a pool permit in Los Angeles?
Submitting complete, engineer-stamped plans on the first pass is the biggest time-saver — plan check corrections add 2–4 weeks per revision cycle.
Why does plaster take 28 days to cure?
Plaster and pebble finishes need a controlled chemistry balancing period after the pool is filled to cure properly and avoid staining or premature wear — this is standard across the industry, not contractor-specific.
Do hillside pools take longer to build in LA?
Yes. Hillside sites require geotechnical reports and additional structural engineering, which can add several weeks to both design and permitting stages.
