Contra Costa County's published pool and spa requirements state that built-in swimming pools and spas must include structural detail and calculations signed and stamped by an engineer. Planning approval, grading, site relationships, and safety requirements can also affect the submittal.
Structural engineering is an express County requirement
The County differentiates built-in pools and spas from portable, listed products. For in-ground work, the permit package should connect the proposed site plan and pool geometry to the structural details, reinforcing, and signed calculations.
We prepare or coordinate that package within the California licensed scope and identify separate survey, geotechnical, grading, or specialty work when needed.
Planning, setbacks, and grading
County guidance notes planning review and provides setback information for unincorporated areas, while cities served by the County may have separate planning contacts. Grading permits are often required for pool installation or abandonment, so the address and scope should be checked before design starts.

Permit authority varies across Contra Costa communities. We confirm whether the project is reviewed by the County building department or a city, then use the current authority's intake requirements for the proposal and plans.
