Do You Need a Permit for a Mini Split?
Usually, yes - somewhere in the project. The mechanical install itself is unpermitted in many places, but the new electrical circuit and disconnect typically require an electrical permit, and some jurisdictions permit the whole HVAC change. Rules are local: your city or county building department is the only authoritative answer, and HOAs add their own layer for condenser placement. Two practical notes: permitted work protects resale (unpermitted HVAC is a standard disclosure fight), and several rebate and warranty paths ask for licensed installation. The premium-brand systems below are the ones most often sold through permitting dealer channels.

Buying notes
- Call the building department before ordering, not after: permit timelines, not install time, set many project schedules.
- True-DIY systems change who does the mechanical work; they do not change the electrical permit picture.
