ADU Maintenance Checklist: Essential Seasonal Care Tips for Canadian Homeowners

Understanding ADU Maintenance Needs

Maintaining an Accessory Dwelling Unit (ADU) is not the same as looking after your main residence. Each unit has its own systems – think separate plumbing, electrical, and HVAC – demanding dedicated care. As illustrated by
BC Housing, the compact design and unique construction of ADUs introduce challenges that require extra vigilance.

For guidance on creating or converting living spaces such as basement suites or garage conversions into legal ADUs, consider our in-depth guide on
