Do You Need a Permit for Outdoor Lighting Installation? in Verenigde Staten
Sometimes. Low-voltage landscape lighting (12V/24V) is typically permit-exempt because it runs on a transformer plugged into an existing outdoor outlet. However, line-voltage (120V/240V) outdoor lighting that involves new circuits, trenching for underground conduit, or connections to the main panel requires an electrical permit. Permanent fixtures on structures may also trigger a building permit.

Country-specific detail
In the US, low-voltage landscape lighting (12V/24V) connected via a transformer to an existing GFCI-protected outdoor outlet is generally permit-exempt. However, any line-voltage outdoor lighting work — adding new 120V/240V circuits, installing dedicated outdoor panels, or trenching for underground conduit — requires an electrical permit per the National Electrical Code (NEC). Post lights, parking area lighting, and security flood lights hardwired to the panel all trigger permits. Municipalities with dark-sky ordinances may impose additional restrictions on fixture type, lumens, and shielding.
