Full Breakdown

040 requires water-heating solar systems to be certified by an accredited listing agency under the California Plumbing and Mechanical Codes, and requires electricity-producing systems to meet California Electrical Code and Underwriters Laboratories standards. 55 and 66015, and Health and Safety Code Section 17951," the state caps on solar and building permit fees.

Violations & Fines

Modifying an existing solar array in a way that materially changes its size, type, or components without obtaining the required new permit under §18.56.020(B) triggers the same enforcement as any unpermitted building work. As a Garden Grove Municipal Code violation, it falls under the citywide general penalty in §1.04.010: a misdemeanor with up to a $1,000 fine, six months in jail, or both, with each day of continued noncompliance a separate offense.

Frequently Asked Questions

What size solar system counts as a small residential rooftop system in Garden Grove?
§18.56.030 caps it at 10 kilowatts alternating-current nameplate rating, or 30 kilowatts thermal, installed on a single- or two-family (duplex) dwelling, with a panel or module array that doesn't exceed the city's maximum legal building height.
Can I submit my solar permit application online?
Yes. §18.56.050 requires the city to post all required application documents on its public website and make electronic submittal, by email, the website, or fax, available to every applicant, and it must accept an electronic signature instead of a wet signature.
Do I need a new permit if I just swap out a broken panel?
No. §18.56.020(B) exempts routine operation, maintenance, and like-kind replacements from needing a new permit; a new permit is only required if the modification materially changes the size, type, or components of the system.
