Basement Renovation in Richmond Hill

Cost depends on the size of the basement, its current condition, any moisture or structural work needed, plumbing (for example adding a bathroom), egress windows, permits and the finishes you choose. Because these vary so much from house to house, AVL gives a written quote after a site visit instead of a generic price range.

It depends on the scope, the permit review time and the inspection schedule. A simple finish is faster than a project with a new bathroom, a separate entrance or structural changes. We give you a schedule for your project once the scope is set.

Many basement projects need a building permit, for example new plumbing, structural changes, new or enlarged window openings, a separate entrance or a second unit. The City of Richmond Hill lists what each type of residential project needs on its Residential Permits page. AVL coordinates the permit application with you; approval is decided by the City.

Whether your existing windows meet the rules depends on their size and height. We check this on the site visit and include any new egress window in the plan and permit drawings.
