Full Breakdown
8 implements the state Solar Rights Act at the local level and keeps the City's own review light-touch. 1 of the City Code. Subsection C makes rooftop and building-mounted solar a permitted use in every zoning district, meaning no discretionary approval stands between a homeowner and a building permit for a standard roof installation, though the code encourages non-reflective panels installed close to the roof pitch and screened equipment. Ground-mounted systems are handled differently by zone: Subsection D allows single-family residential lots to install a stand-alone ground-mounted system through administrative Zoning Clearance if it sits in the rear or side yard and meets the accessory-structure standards in Table 25-7, while every other zoning district requires Minor Discretionary Review instead.
Solar carports over a parking lot also go through Minor Discretionary Review under Subsection E, but are exempted from the lot's internal landscaping requirement for the area the panels cover, and cannot cause a net loss of required parking spaces. 6(A)(5) additionally lets a solar energy system rise up to 10 feet above the district's normal height limit, with the Director able to approve more if needed to avoid a significant cost increase or efficiency loss. Commercial solar farms are treated as public utilities and confined to the IBP, IL, and IG industrial zones under a Conditional Use Permit.
Violations & Fines
Installing a solar energy system without the required building permit, or a ground-mounted or carport system without the applicable Zoning Clearance or Minor Discretionary Review, is enforced as a City Code violation through Administrative Citation under Chapter 1, Article II. Under the Section 1.7 general penalty, a first offense is an infraction up to $100, a second within a year up to $250, and later violations can be charged as a misdemeanor with a fine up to $1,000 or six months in county jail.
