ADU Construction cost in Lakewood

An ADU is a zoning project before it is a construction project. Setbacks, lot coverage, parking relief, owner-occupancy rules and utility capacity decide what can legally go on your lot, and they vary street by street.
High-altitude UV, big temperature swings and real snow load mean assemblies rated for a mild climate fail early here.
Garage conversions read as the cheap route and often are, but the slab usually sits below the required floor height and lacks a moisture barrier, so the real scope includes the floor system most quotes leave out.
What the job includes
- Zoning and feasibility review
- Plan sets and permit submittal
- Detached, attached and garage conversions
- Separate utility metering
- Kitchen and bath rough-in
- Final inspection and occupancy sign-off

Lakewood sits in IECC climate zone 5B (Cold).4 In a cold climate zone, insulation, air sealing and heating design dominate the ADU's energy-code review.
The median owner-occupied home in Lakewood is valued at $574,400 (ACS), above the Colorado median of $539,400.1 Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have. Heating dominates the year: about 5,765 heating degree days against 813 cooling degree days (base 65°F).5,6 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope.
