Garage Construction Denver, CO
Adding a garage to your Denver property is one of the few home improvement projects that pays back on multiple fronts — storage, workspace, property value, and in many cases, the foundation for a future ADU above it. Arch Design & Build designs and builds detached garages and garage additions across the Denver Metro Area, from permit application through final inspection
How Much Does Garage Construction Cost in Denver?
Starting from $30,000.
A single-car detached garage on a straightforward lot sits at the lower end. A two-car structure with finished interior, electrical service, and an ADU-ready second floor is a significantly different project. What moves the number most: site conditions, lot setbacks, Denver zoning classification, and whether you’re building ADU-ready from the start or purely functional.
Denver’s older neighborhoods — Washington Park, Hilltop, Congress Park — often have tight lot lines and specific setback requirements that affect footprint options. We assess all of that before design begins.

Build It Right the First Time
The most common mistake in garage construction: building without thinking about what comes next.
A garage built to basic code today costs significantly more to convert into an ADU or living space later — because the foundation, framing, insulation, and electrical weren’t designed for that use. If there’s any chance you’ll want a rental unit, a studio, or a guest space above the garage in the next 10 years, designing for that from the start adds a fraction of the eventual cost.
We’ll ask the question during the consultation. If ADU-ready construction makes sense for your lot and your plans, we design to that standard from day one. Full details on zoning eligibility, permitting, and what a legal ADU requires are on our ADU Construction page →.

Denver Permits for Garage Construction
New garage construction in Denver requires a building permit through Denver Community Planning and Development, plus electrical permits for any service connections. Lots in older Denver neighborhoods are subject to specific setback rules, height restrictions, and lot coverage limits that affect what can be built and where.
We manage every application, every zoning review, and every inspection. You don’t fill out a form.

Frequently Asked Questions
Can I build a garage on my Denver lot?
Most single-family lots in Denver can accommodate a detached garage, but setback requirements, lot coverage limits, and zoning classification all factor into what’s possible. We confirm eligibility and design within those constraints during the site assessment — before any design dollars are spent.
What’s the difference between a standard garage and an ADU-ready build?
A standard garage is built to store vehicles and equipment. An ADU-ready garage is built with a foundation, framing, insulation, and electrical service sized for future habitable use above. The cost difference during initial construction is far smaller than the cost of retrofitting a standard structure later.
How long does garage construction take in Denver?
A standard single or two-car garage runs 8–12 weeks from permit approval. An ADU-ready two-story structure: 14–20 weeks. Denver CPD permit review is built into the timeline from day one.
