Milpitas, CA Solar Energy: Expedited Solar Permitting (2026)

Milpitas Municipal Code Chapter II-1.5, adopted by Ordinance No. 65.144 on June 16, 2015 to implement California's Solar Rights Act and AB 2188 (Stats. 2014, ch. 521), sets up a mandatory administrative review track for 'small residential rooftop solar energy systems': systems no larger than 10 kilowatts AC nameplate rating or 30 kilowatts thermal, installed on a single-family or duplex dwelling, that meet state fire, structural and electrical codes and do not exceed the City's maximum legal building height. Under Section II-1.5-6.01, the Building Department must issue the permit the same day for an over-the-counter application, or within one to three business days for an electronic submission, once the application matches the City's approved standard plan and checklist; review is limited to whether the application meets local, state and federal health and safety requirements (II-1.5-6.02).

A building official may instead require a discretionary use permit only on written findings, backed by substantial evidence, that the installation would cause a specific, adverse public health or safety impact with no feasible mitigation; that decision, and the underlying permit decision, can both be appealed to the City Planning Commission (II-1.5-6.01, 6.03). Only one inspection is required for an eligible system, and the City must schedule it within two business days of the request with a two-hour window (II-1.5-6.08, 6.09); a failed inspection allows a follow-up inspection that need not meet the expedited timeline (II-1.5-6.10).

Electronic submittal by email, web portal or fax and electronic signatures must be accepted on every application (II-1.5-5.02, 5.03), and permit fees must comply with Government Code Sections 65850.55, 66015 and 66016 and Health and Safety Code Section 17951. Systems already permitted before the Ordinance took effect are grandfathered unless later altered in a way that changes size, type or components (II-1.5-3.02).
