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.
text
Occupancy, energy code, and ADUs
Turning an unconditioned garage into a bedroom is a change of space conditioning. Denver Energy Code Chapter 5 [RE] treats that as a change of occupancy or use and applies addition/new-construction energy rules to the newly conditioned space. Creating a separate ADU is a different zoning path: the district must allow an accessory dwelling unit, and plans must clearly label the ADU and the primary structure. Transportation review is listed for ADUs, garages, and increases in dwelling units.
text
Permits and who coordinates the work
City and County of Denver Community Planning and Development requires architectural and structural review for occupancy or use changes, plus zoning, building, and typically SUDP. Exterior changes on landmarks or in historic districts need Landmark review. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades plus the design professionals required for the project.

What buyers should prepare
Attached versus detached, living space versus ADU, whether a bath or kitchen is included, and how parking will be handled.
FAQ
Common questions
Does converting a garage need a Denver permit?
Yes. It is a change of occupancy or use. CPD requires building and zoning review, and typically SUDP.
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?
No. Extra rooms for the main house stay one dwelling. An ADU is a separate dwelling and is only allowed in districts that permit it.
Does energy code apply to a cold garage?
Yes once it becomes conditioned. Denver Energy Code uses turning an unconditioned garage into a bedroom as an example of a change of space conditioning.
What information helps define scope?
Attached vs detached, ADU vs extra rooms, parking plan, and city or county.
