Summary
In the City of Milpitas, building a residential swimming pool or spa requires a permit reviewed under the same Title II, Chapter 1 permit process that governs every adopted construction code, since Milpitas Municipal Code Chapter II-10 designates the 2024 International Swimming Pool and Spa Code as the City's pool code and Section II-1-1.01 folds its administration into the citywide permit system.
The purpose of this Chapter is to provide for the administration and enforcement of codes and municipal ordinances within the Milpitas Municipal Code, Title II. For each code adopted by reference in Title II, the administration chapter of each code provides for the code's scope and administration and is hereby adopted, unless specific sections for the administration and enforcement of the codes are provided under this Chapter. Collectively with the sections in this Chapter, they provide for the administration and enforcement of the codes and municipal ordinances in Title II. ... The 2024 International Swimming Pool and Spa Code, published by the International Code Council, Inc., is hereby adopted and referred to, and by this reference expressly incorporated and made a part of this Chapter as though fully set forth herein. The 2024 International Swimming Pool and Spa Code shall be designated and referred to as the "Swimming Pool and Spa Code" for the City of Milpitas. There is one copy of said Code on file in the office of the Building Official for use and examination by the public.
Full Breakdown
The City of Milpitas designates the 2024 International Swimming Pool and Spa Code, published by the International Code Council, as the City's 'Swimming Pool and Spa Code' under Milpitas Municipal Code Section II-10-1.01, and Section II-1-1.01 folds that code's administration into the same permit process that governs every other construction code adopted in Title II. That means a residential pool or spa goes through the standard Building Department review: the Building Official checks the plans, specifications and fee payment against the code before issuing the permit (Section II-1-8.01), and the permit fee itself is set by City Council resolution (Section II-1-9.01).
No Building or Occupancy Permit for the pool structure can issue until any conditions the Planning Commission or City Council attached to the property's development or subdivision have been satisfied (Section II-1-3.07). Once issued, the permit expires if work is not started or inspected within 12 months, or if construction is suspended for 180 days, in which case resuming costs half the original fee unless the gap runs past 360 days (Section II-1-8.04). Pool excavation below finished grade that is authorized by a valid building permit is exempt from needing a separate grading permit under Chapter II-13, but that exemption does not cover fill placed from the excavation or any excavation left with an unsupported height greater than five feet once the pool structure is complete (Section II-13-4.01).
Building without the required permit is unlawful and can draw the same civil penalty of $100 to $1,000 per day under Section II-1-5.04 that applies across Title II.
Violations & Fines
Constructing a pool or spa without the required City permit is unlawful under Milpitas Municipal Code Section II-1-5.01 and exposes the owner to a civil penalty of $100 to $1,000 per day the violation continues under Section II-1-5.04, on top of inspection and abatement costs, recoverable through Santa Clara County Superior Court. Excavating below grade beyond the five-foot unsupported-height exemption in Section II-13-4.01 without the matching grading permit is a separate violation of Chapter II-13.
