Denver additions, ADUs and whole-home remodels.
Design-build across Denver’s older neighbourhoods — additions, pop-tops, accessory dwelling units and structural remodels, documented from the excavation through to the final walk.
Denver just made ADUs legal on most of the city. Almost nobody has told homeowners.
In December 2024 a citywide rezoning took effect that lifted the share of Denver land where an accessory dwelling unit is allowed from roughly 36 per cent of the city to about 70 per cent. If you looked into an ADU before that and were told no, the answer has probably changed — and the owner-occupancy requirement that used to make them impractical for a lot of people is gone.
Verified against official City and County of Denver and Colorado Department of Local Affairs sources as of August 2026. Code editions and ADU rules change, and several Front Range jurisdictions are mid-revision right now. Treat this as the starting point for your project, not as legal advice, and confirm the current standard with Denver Community Planning and Development before you commit to a design. We do that on every job as a matter of course.
Denver work we documented from demolition to the final walk.

Denver Home Addition, Kitchen & Bath
A rear addition tied into the existing structure, with the kitchen and bathroom rebuilt around the new plan rather than squeezed into the old one.
Denver Pop-Top, Detached ADU & Whole-Home Remodel
A full second storey framed above the original brick, a two-bedroom ADU over a new detached garage, and the whole house back to the studs — photographed from demolition to the finished elevation.Denver questions we get asked.
Can I build an ADU in Denver?
On most of the city now, yes. The citywide ADU rezoning adopted on 18 November 2024 and effective 16 December 2024 raised ADU-eligible land from roughly 36% of Denver to roughly 70%, and removed the owner-occupancy requirement. There is no citywide square-footage cap — your zone district sets the limit — and the lot-coverage exemption now extends to ADUs, which is often what makes a narrow lot work. If you were told no before 2025, it is worth asking again.
Which building code will my Denver plans be drawn to?
The 2025 Denver Building and Fire Code, adopted 13 June 2025 and effective 31 December 2025. It is based on the 2024 I-Codes but Denver amends heavily, so it is not interchangeable with a neighbouring jurisdiction's code. Plans drawn to a generic 2024 IRC set are not automatically Denver-compliant.
My house is in a historic district. What does that add?
A Certificate of Appropriateness. In Denver it is mandatory for exterior work, development or demolition both on designated landmarks and on any property inside a historic district, and it must be submitted alongside the building and zoning permit rather than after. It does not stop a project, but it has to be planned into the schedule from the start, and it shapes exterior material and window decisions.

Bring us the house you already love.
We will look at what is standing, what it can carry and what Denver zoning allows on your lot — then tell you honestly what it takes. It starts with a short phone consult, not a sales visit.
