San Mateo County's pool or spa permit page calls for a plot plan showing the entire property, construction details, engineering data with signed calculations, a geotechnical report, and energy information. The County also publishes survey requirements that can affect swimming-pool projects and setback verification.
The County expects the property context
The plot plan is expected to show the proposed pool and equipment together with driveways, walkways, parking, wells, retaining walls, utilities, easements, trees, and structures. That breadth makes a reliable survey or accepted property base especially important.
We coordinate the pool layout, structural sections, scoped trade information, and calculations to the same site plan and identify geotechnical or survey work that must be supplied separately.
Calculations and geotechnical information
The County lists signed engineering calculations and a geotechnical report for pool or spa applications. The structural design must use the final project geometry and the relevant site recommendations rather than generic assumptions that conflict with the supplied report.
County jurisdiction versus incorporated cities
A San Mateo County mailing address does not always mean the County is the permit authority. We confirm whether the property is in an incorporated city or unincorporated County area before relying on a checklist or pricing the package.

Frequently asked questions
Does San Mateo County require a geotechnical report for a pool?
The County's published pool or spa permit page lists engineering data including signed calculations and a geotechnical report. Confirm the current requirement for the specific property with the reviewing authority.
Do you verify whether the County or a city reviews the project?
Yes. We start with the address and parcel because incorporated cities within San Mateo County can use their own permit checklists and processes.
