ADU Construction in Denver — Turning Unused Space Into Usable Living
Superior Construction & Home Renovations is an ADU contractor serving the Denver Metro area, helping homeowners convert underused lots, garages, and basements into permitted, code-compliant accessory dwelling units. Their work spans the full process — from zoning evaluation and floor plan development to permitting and final inspection.
An accessory dwelling unit is a secondary residential unit built on the same lot as a primary home. In Denver, that can take several forms:
- A backyard cottage or detached ADU built in the rear yard
- A garage conversion or garage apartment
- A basement ADU or mother-in-law suite with its own kitchen, bath, and sleeping area
- A carriage house or similar accessory structure
Denver now allows accessory dwelling units across approximately 70% of residential land, following a 2024 citywide measure that took effect on December 16, 2024. That's a significant expansion from the previous 36%, and it opens up real options for homeowners who previously weren't eligible.
What Superior Construction Handles as Your ADU Builder
Superior Construction & Home Renovations positions itself as a full-service ADU builder — meaning they manage more than just the physical construction. Their process includes:
- Site analysis and zoning verification — confirming what your lot can support under Denver's current zoning code
- Floor plan development — shaping a layout that fits your property and goals
- Construction document preparation — producing the drawings and documentation required for permits
- Permitting management — handling zoning review, building review, and sewer use and drainage approval with the City of Denver
- Construction and project management — carrying the build through to final inspection with one accountable team
The City of Denver requires every ADU project to go through zoning review, building review, and sewer and drainage approval. Superior Construction confirms eligibility before any design work begins, at no charge to the homeowner.
Not every property qualifies for every type of ADU. Eligibility depends on the zoning district, lot size, and existing structures on the property. A site that works well for a detached ADU or backyard cottage builder project may not support the same layout as a garage conversion — and vice versa. That's why the feasibility check comes first.
Why Denver Homeowners Consider ADU Construction
There are several practical reasons homeowners in Denver pursue ADU construction:
- Rental income: A permitted secondary unit can generate long-term rental income or, where city rules allow, short-term rental income.
- Multi-generational living: An in-law suite or granny flat allows aging parents or adult children to live nearby while maintaining separate living spaces.
- Property value: A permitted ADU adds equity that standard renovations often don't match, and it continues to generate returns while you own the property.
- Flexibility: An ADU can serve as a home office, a guest space, or a rental unit depending on what your situation calls for at any given time.
Superior Construction & Home Renovations specializes in residential construction and remodeling, with a focus on new home additions, custom builds, and structural remodels. Their ADU work is part of a broader service offering that includes home renovations across the Denver Metro area.
Every property is different, and the right ADU type depends on the lot, the budget, and the homeowner's long-term plans. Superior Construction works with homeowners to identify which option — whether a Casita, a basement conversion, or a detached backyard unit — fits their specific situation before any commitments are made.
