Summary

In unincorporated Monterey County, small rooftop solar systems up to 10 kilowatts AC (or 30 kilowatts thermal) on a detached single-family home or duplex qualify for a nondiscretionary, administratively reviewed permit under Chapter 18.17, with the Building Official's review limited to health-and-safety compliance rather than discretionary design review.

City-specific rules exist: Salinas has its own expedited solar permitting rules that differ from Monterey County's county-level regulations. If you live in Salinas, check the city-specific page instead.

Applications for small residential rooftop solar energy systems shall be administratively reviewed and acted upon by the Building Official as nondiscretionary permits within a reasonable time following receipt of a complete application that meets the requirements of the County's checklist, standard plans, and payment of all required permit processing and inspection fees. The Building Official's review shall be limited to whether the proposed small residential rooftop solar energy system meets all health and safety requirements of local, State, and Federal law. The requirements of local law shall be limited to those standards and regulations necessary to ensure that the solar energy system will not have a specific, adverse impact upon the public health and safety.

Full Breakdown

17 (Ord. No. 5258, effective 9-29-2015) to comply with the State Solar Rights Act and AB 2188, creating a streamlined, nondiscretionary process for "small residential rooftop solar energy systems" in the unincorporated county; incorporated cities such as Salinas, Monterey, Seaside, Marina, Carmel-by-the-Sea, Pacific Grove and King City run their own permitting programs and are not covered by this chapter. 030(E), a system must be no larger than 10 kilowatts AC nameplate rating or 30 kilowatts thermal, meet applicable state fire, structural and electrical code standards, sit on the rooftop of a detached single-family dwelling or duplex, and not exceed the zoning district's maximum building height.

050(A)-(B). 050(E), a complete application is reviewed and acted on by the Building Official as a nondiscretionary permit, with review limited to whether the system meets health and safety requirements of local, state and federal law; local standards are confined to those necessary to prevent a "specific, adverse impact" on public health and safety. 050(F) allows the official to require a discretionary use permit instead, a decision appealable to the County Planning Commission. 050(G). 060 caps expedited review at one Building Official inspection, preceded by a separate fire authority inspection; a failed inspection triggers a follow-up inspection outside the expedited timeline. 55, 66015 and 66016 and Health and Safety Code Section 17951.

Violations & Fines

Chapter 18.17 sets no fine schedule; noncompliance instead removes the expedited path. Systems exceeding 10 kW AC/30 kW thermal, mounted on buildings other than a detached single-family home or duplex, or flagged for a specific adverse impact under Section 18.17.050(F) lose nondiscretionary review and must obtain a standard discretionary use permit, appealable first to the Planning Commission and, where the Commission decided, to the Board of Supervisors under Section 18.17.050(G).

Frequently Asked Questions

Does unincorporated Monterey County offer expedited solar permitting?
Yes. Chapter 18.17 requires the Building Official to run an administrative, nondiscretionary review for small residential rooftop solar systems that meet the chapter's size and building-type limits, rather than routing them through discretionary design review, per Section 18.17.040(A).
What size solar system qualifies for expedited review?
Under Section 18.17.030(E), the system must be no larger than 10 kilowatts AC nameplate rating, or 30 kilowatts thermal, installed on the rooftop of a detached single-family dwelling or duplex, and must not exceed the zoning district's maximum building height limit.
Can the County require a discretionary use permit instead of expedited review?
Yes. Section 18.17.050(F) lets the Building Official require a use permit if substantial evidence shows the system could have a "specific, adverse impact" on public health or safety; that requirement can be appealed to the County Planning Commission.
How many inspections does an expedited solar permit require?
Section 18.17.060 limits the Building Official to one inspection for systems approved through expedited review, but requires a separate fire authority inspection first. If the system fails, a follow-up inspection is authorized outside that one-inspection limit.
