Can I install landscape lighting without an electrician?

Installing landscape lighting yourself depends on the type of system and power source, but most installations in Ontario require a licensed electrician due to ESA permit requirements and safety concerns.

For low-voltage LED landscape lighting systems (12V or 24V), homeowners can legally install the fixtures and run the low-voltage wiring themselves. These systems use a transformer that plugs into an existing outdoor outlet, stepping down household voltage to safe levels. You can install path lights, spotlights, and deck lighting without permits as long as you're not modifying any electrical circuits or installing new outlets.

However, line voltage systems (120V) absolutely require a licensed electrician and ESA permits. This includes any new outdoor outlets, underground wiring, or connections to your home's electrical panel. Even if you want to add a simple outlet for your low-voltage transformer, that requires professional installation and inspection.

Safety considerations make professional installation worth considering even for low-voltage systems. Outdoor electrical work involves weatherproofing, proper burial depths for cables, and understanding how moisture affects connections. Improper installation can lead to shorts, fixture failure, or even electrocution if water enters connections.

ESA requirements in Ontario are strict about outdoor electrical work. Any new circuits, outlets, or modifications to existing wiring need permits and inspections. The typical cost for having a licensed electrician install a basic low-voltage landscape lighting system ranges from $800 to $2,000, depending on the number of fixtures and complexity of the layout.

What you can safely do yourself includes planning your lighting layout, selecting fixtures, and installing low-voltage LED systems that plug into existing outdoor outlets. Always ensure any outdoor outlets you use have GFCI protection - this is required by the Ontario Electrical Safety Code for all outdoor locations.
