Orange County Pool Builder

Custom Pool Builder in
Rancho Santa Margarita, CA

Rancho Santa Margarita has been its own city since 2000, built as a master-planned community around the lake and the foothills of the Santa Ana Mountains. Most neighborhoods are family lots where a pool and spa have to share the yard, while gated Dove Canyon and other hillside areas have slope and views to design around.

Association review is part of nearly every project here, and slope lots add drainage and geotechnical planning. We design to the guidelines and the grade from the first draft so the plans pass review without rework.

Permitting & HOA

City Permits & Association Review

Pool permits come from the City of Rancho Santa Margarita. Most neighborhoods also sit under a master association and often a neighborhood association, each with architectural review of exterior work.

We prepare the city permit and association packages together. On hillside lots we add engineered drainage and geotechnical review before anything is submitted, so the reviews see a complete, engineered plan.
