Solar Energy in Riverside, CA: What Residents Actually Need to Know

Riverside maintains 190 local ordinances across all categories, and 2 of those deal specifically with solar energy. Here is a breakdown of what the city actually requires, what is prohibited, and where Riverside falls on the strict-to-permissive spectrum compared to other cities.

Expedited Solar Permitting

Riverside runs a streamlined solar permit track under RMC Chapter 16.22 for rooftop systems up to 10 kW AC or 30 kW thermal on single- or duplex-family homes. Applications go in electronically, and only one Building and Safety Division inspection is required for eligible systems.

Key details: Max system size: 10 kW AC or 30 kW thermal. Eligible buildings: Single- or duplex-family rooftops only. Inspections required: One, if application is compliant. Application method: Electronic, via City website software. State law compliance: Solar Rights Act; AB 2188 (2014).

An incomplete application doesn't get rejected outright: the applicant receives a written correction notice under § 16.22.060 spelling out every deficiency and must resubmit to stay on the expedited track. The one-inspection guarantee is conditional: if the system fails that inspection, a follow-up inspection is authorized, but the ordinance's expedited-review requirements no longer bind it, so a failed first inspection can push the project outside the streamlined timeline. There is no separate fine schedule in this chapter; noncompliant installs fall back to the City's general building-permit enforcement under Chapter 16.04.

If you are coming from a city with tighter rules, you will find Riverside gives residents more flexibility on expedited solar permitting.

HOA Restrictions

California's Solar Rights Act (Civil Code Section 714) protects Riverside homeowners' rights to install solar energy systems. HOAs cannot effectively prohibit solar installations. Restrictions that increase system cost by more than $1,000 or decrease efficiency by more than 10 percent are void and unenforceable. The Solar Rights Act applies to all HOAs in Riverside regardless of CC&R language.

Key details: State Law: CA Civil Code §714. Solar Rights Act. HOA Limits: Cannot effectively prohibit solar. Cost Threshold: Cannot increase cost by more than $1,000. Efficiency Threshold: Cannot reduce efficiency by more than 10%. CC&Rs: Restrictive provisions are void.

Riverside is more permissive than most cities when it comes to hoa restrictions. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Riverside gives residents more room on solar energy. 2 of the 2 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
