Minnesota Solar Access and Permitting Preemption

Minnesota law establishes a strong solar access policy. Section 462.357 subd. 1g allows municipalities to regulate solar but bars unreasonable restrictions on installation, performance, or function. Section 500.30 creates solar easements as recordable property interests. Permitting authority remains local under the State Building Code, but cities cannot prohibit solar outright on residential property nor impose aesthetic-only bans. Electrical permits are mandatory under Minn. Stat. 326B.31 and must use NEC standards. Net metering for systems up to 1 megawatt is required under Minn. Stat. 216B.164 from regulated utilities, providing retail credit for excess generation.

Unreasonable local solar bans may be challenged in district court. Installing a solar system without electrical or building permits triggers stop-work orders and double permit fees.
