What garage conversion covers

Garage conversions in the Denver metro turn an attached or detached garage into conditioned living space or, where zoning allows, an accessory dwelling unit. Work typically includes insulation, new openings, electrical, HVAC, and often a bath or kitchen. Parking on the lot still has to satisfy zoning. A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Cost is project-specific and depends on attached versus detached, ADU versus extra rooms, and how much of the envelope changes.

What buyers should prepare

Attached versus detached, living space versus ADU, whether a bath or kitchen is included, and how parking will be handled.

Who handles garage conversion permits and licensing?

A municipally licensed Denver general contractor coordinates the project, design professionals, and specialty trades. Colorado has no statewide general contractor license.

Is extra living space the same as an ADU?
