Denver Zoning and Permits for ADU Conversion

Before you can calculate an adu conversion cost denver, you need to understand the local zoning and permit rules. Denver allows accessory dwelling units in most residential zones, from R-0 through R-4, but your project must meet specific dimensional standards before you begin.

For attached ADUs, the primary lot must be at least 5,000 square feet. A detached structure, such as a garage conversion ADU cost denver is heavily influenced by setback rules, requires a minimum lot of 6,000 square feet. Height for any detached ADU is capped at 24 feet, and all setbacks must mirror what the underlying zone requires for the primary residence. The city also mandates one off-street parking space unless your property sits within a reduced-parking zone or near a high-frequency transit corridor.

All conversions require proper Denver building permits, submitted through the city’s ePermits portal. Your application must include a site plan, floor plan, elevations, and energy calculations. After submission, expect inspections at foundation, framing, and final stages. Because Denver mandates owner occupancy for at least one unit during the first three years, an owner-attestation form must accompany your paperwork. We recommend verifying your zone’s rules with the city or consulting a professional, as Denver’s regulations are subject to change.

With your zoning and permit path mapped, let’s break down the average adu conversion cost in Denver. A basement adu conversion cost denver often varies based on the extent of foundation work and utility upgrades required.
