Summary
Hesperia allows roof-mounted solar as an accessory use without discretionary review in residential zones, while ground-mounted panels need a rear-yard siting finding and larger systems trigger extra approvals.
Roof-mounted solar energy systems: Allowed as an accessory structure on a developed lot. Roof-mounted solar systems should be designed approximately parallel to the roof plane or integral to the roof material. ... Ground-mounted solar energy systems: Allowed as an accessory structure within the rear yard of a developed lot if a roof-mounted system is deemed infeasible.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 24 Update 2).
Full Breakdown
Roof-mounted solar energy systems are allowed as an accessory structure on any developed lot, by right in residential and agricultural districts, though commercial and industrial installations may need a Revised Site Plan Review. Ground-mounted systems are permitted only in the rear yard, and only when a roof-mounted system is shown infeasible due to roof configuration, shading, or orientation. Any system covering more than 15% of the lot area is reclassified as a solar farm, restricted to nonresidential and nonagricultural land, and requires a conditional use permit from the planning commission.
Violations & Fines
Installing a ground-mounted or oversized solar system without the required site plan review or conditional use permit is a zoning violation, and the system can be ordered modified, relocated, or removed.
