Midway City, CA Swimming Pools & Spas: Pool Permits (2026)

Pools and spas in unincorporated Orange County are regulated by OC Public Works / OC Development Services. The Swimming Pool and Spa Packet states that the County requires building permits to be obtained before construction or change in occupancy can begin, and building plans are required for permit issuance. Plans are reviewed for compliance with County Building Ordinances (Building, Plumbing, Mechanical and Electrical Codes) and State regulations such as the Energy Conservation Regulations and accessibility standards. The applicant submits a Building Permit Application and Pool/Spa Questionnaire at myOCeServices.ocgov.com, plus plans in PDF format that include a site plan showing existing and new structures with setback dimensions and proposed pool safety fencing, cross-sections in both directions extending at least 5 feet beyond property lines, the pool/spa plan with structural details, and structural calculations if a non-standard plan is used. A soil report is required if the pool is located less than 15 feet from the top of a slope or 8 feet from the toe of a slope steeper than 1 unit vertical in 3 horizontal, unless the listed exceptions are met. Planning approval is required prior to permit issuance, the plan check fee must be paid, and issuance requires Workers' Compensation insurance plus a California licensed contractor ID (or it may be issued as Owner-Builder). Special inspection is required during gunite or shotcrete placement per 2019 CBC.
