Accessory Dwelling Units — or ADUs — are becoming increasingly popular in Denver. Whether you’re building a backyard cottage, converting a garage, or adding a basement apartment, ADUs can offer rental income, multigenerational housing, or increased property value. But before you get started, you’ll need to navigate one of the most complex permit processes in the city.
Denver has very specific zoning, building, and design requirements for ADUs — and unfortunately, they’re not always easy to interpret without professional help.
What Makes ADU Permits in Denver So Challenging?
While Denver is relatively ADU-friendly compared to other cities, the approval process is still rigorous. Some of the common roadblocks include:
- Zoning limitations: Not every lot is eligible for an ADU. Zoning must allow for two units.
- Lot size and placement: There are minimum lot size requirements and rules for ADU height, setbacks, and design.
- Owner occupancy requirements: In some cases, the owner must live in one of the units.
- Parking requirements: Additional off-street parking may be required.
- Neighborhood overlays and design standards: Historic districts or design overlays may limit what you can build.
Each of these factors must be reviewed and approved by Denver’s Community Planning & Development department before you can move forward.
