Questions homeowners ask

Can every garage become living space?

Not always. Ceiling height, structure, utilities, parking rules, fire separation, and access all need review before committing to a scope.

Can a garage conversion include a bathroom?

Often yes, but plumbing route, sewer access, slab conditions, and permit requirements affect cost and feasibility.

Is a garage conversion cheaper than an addition?

Usually it can be, because the shell already exists, but structural upgrades, utilities, and finish level still drive the budget.
