Summary
Unincorporated Ada County lets a homeowner install solar panels on an existing detached structure through a simple Director-issued zoning certificate, even if the structure itself doesn't meet current zoning rules. No public notice or hearing applies to this permit type.
E. Decision: 1. The Director shall review the zoning certificate application and shall: a. Approve the application; b. Deny the application; or c. Approve the application with conditions. 2. The Director shall not issue a zoning certificate for any use on a property that violates this Title or on a property that contains structures or uses that violate this Title, with the exception that a zoning certificate may be issued exclusively for the installation of solar panels on any existing detached structure constructed prior to January 1, 2000, or increased in size after January 1, 2000, regardless of its current zoning status. Any zoning certificate secured that violates state or federal law is invalid.

Full Breakdown
Ada County Code section 8-6-32 normally bars the Zoning Director from issuing a zoning certificate for any property containing a structure or use that violates Title 8. 2 carves out solar: a zoning certificate can issue exclusively for installing solar panels on an existing detached structure built before January 1, 2000, or enlarged after that date, regardless of the structure's current zoning status. B), and under subsection D notice to neighbors is expressly "not applicable," so there is no neighborhood meeting or public hearing step that applies to most other Title 8 approvals.
1), and any certificate that ends up violating state or federal law is void regardless of the county's approval. 4). Denials or conditions attached to the certificate can be appealed under section 8-6-13. The carve-out is narrow: it only reaches solar panels mounted on a qualifying existing detached structure such as a shed, barn, or garage, not new construction or ground-mount arrays built as a standalone use.
Violations & Fines
If a property owner begins panel installation before the Director issues the zoning certificate, or breaches a condition attached to it, section 8-6-32.H.5 lets the Director order all further work on the project stopped until the violation is corrected. Work cannot lawfully resume until the certificate is obtained or the condition is remedied.
