Denver ADU Zoning and Rezoning: What Changed

Denver expanded ADU access citywide, but that does not mean every lot can build the same ADU. Form standards, setbacks, building coverage, utilities, and design still matter.

Citywide Access Is Not Automatic Feasibility

Denver’s citywide ADU changes opened the door for many homeowners, but an individual project still depends on lot size, zone district, existing structures, rear-yard conditions, utilities, and building code.

What to Check First

Start with your zone district, lot dimensions, existing building footprint, alley or side access, utility route, and whether the ADU will be detached, above-garage, basement, or internal. A small zoning green light can still run into cost or buildability issues.

Rezoning vs ADU Planning

Before citywide access, many homeowners had to think about rezoning just to pursue an ADU. Now the more common question is practical feasibility: what can fit, what it costs, and what professional team is needed.

Advisor Next Step

Use the quiz to organize your address, property type, and goal. Then verify details with Denver Community Planning and Development or a qualified local professional before spending serious design money.

Start with the ADU quiz. It captures your property type, goals, budget range, and readiness questions so the next step is focused. Take the ADU readiness quiz.
