Mudrooms are one of Ontario’s most practical home upgrades given the winter weather. Here is how to design, budget, and permit one effectively.
Mudroom Configurations
Garage entry mudroom: Convert existing garage entry. Most common in Ontario suburbs. Typically built-in cubbies, bench, hooks, tile or LVP floor. Side entry addition: Small addition off existing door. Adds 40-100 sq ft. Requires building permit if over code threshold. Front vestibule: Enclosed front entry acting as thermal air lock — popular in older Ontario homes for energy efficiency.
Essential Features
Tile or LVP flooring (waterproof, durable, cleanable). Built-in bench with shoe storage below. Individual cubbies or lockers with coat hooks. Upper cabinets for seasonal storage. Dedicated electrical outlet. Floor drain if possible.
Permit Requirements
Mudrooms within existing footprint: permit needed only if structural or plumbing changes involved. Additions to home footprint: full building permit required with setback compliance and drawings.
