The fine print, up front
Why Conejo numbers move
Narrow side yards in Newbury Park tracts mean smaller machines and longer excavation. Hillside lots in Lake Sherwood, North Ranch, and the Bell Canyon edges mean engineering and retaining. Both show up in the site line, not in a surprise change order.
Parts of the valley dig clean; parts hit rock and expansive soil. A soils report settles the question where the building department requires one, and the footing design follows it.
Excavated soil has to go somewhere legal. Haul distance from Camarillo and Ventura job sites is a real line in a real estimate.
Plaster, pebble, and quartz finishes, Baja shelves, water and fire features: this is the part of the budget you control completely, and the part to price after the site lines are honest.

Cost questions
A custom gunite pool typically runs $90,000–$165,000 fully installed in the Conejo Valley. Plunge pools and spools start in the $60,000s. Hillside and luxury builds run $165,000 and up. Those are market planning ranges for this area, updated October 2026; your line-item estimate after a site visit is the real number.
National cost guides average in markets where a basic pool starts at $33,000–$65,000. California labour, permits, engineering, and disposal costs sit in a different band, and the Conejo Valley sits at the top of the California band. A national average pasted onto a Conejo page is the aggregator move. We do not make it.
Design, permits, excavation, steel, plumbing, electrical, gunite shell, standard finish, standard equipment set, included decking band, fencing or safety features as required, and startup. Retaining walls beyond a stated allowance, landscaping beyond decking, and utility upgrades are not included. The included / not included table on this page is the full list.
An attached spillover spa typically adds $14,000–$22,000. A separate spa typically adds $20,000–$32,000. Both figures cover the shell, plumbing, equipment share, and finish at local rates.
Yes. Engineering, a soils report, deeper footings, retaining, and harder excavation and access add $25,000–$55,000 on a true hillside build before any luxury finish is picked. Thousand Oaks code §1808.7.3 also pushes pools back from slope edges, which can shrink or reshape the design. The calculator prices the hillside line openly.
No, and be wary of any site that offers one. Soil, access, slope, and utility runs are invisible from a website. What you can get online is an honest ballpark, which is what the calculator gives you, and then an exact line-item estimate after a site visit, which is what the free consultation is for.
