AAA Home Improvements
Description
AAA Home Improvements is a Denver-based ADU contractor helping homeowners throughout the Front Range design, permit, and build custom accessory dwelling units. Their services are geared toward homeowners looking to create additional living space, support multigenerational living arrangements, or generate rental income through a professionally managed ADU project.
As housing costs continue rising across Colorado, accessory dwelling units have become an increasingly practical solution for homeowners seeking long-term flexibility and added property value.
Why More Colorado Homeowners Are Building ADUs
Several factors have contributed to the growing demand for ADUs across Denver and surrounding communities:
- Rising housing costs have made ADUs a more affordable option for housing family members or generating supplemental income.
- Updated zoning regulations in cities like Denver, Lakewood, Arvada, and Littleton now allow more residential properties to accommodate ADUs.
- Aging-in-place planning has encouraged homeowners to create nearby living space for parents, caregivers, or adult children.
- Denver’s competitive rental market has increased interest in detached ADUs and garage conversions as income-producing units.
- Well-designed ADUs can improve both property functionality and long-term resale value.
AAA Home Improvements works closely with homeowners to determine which ADU approach best fits their lot, goals, and budget before moving into design and construction.
Types of ADUs AAA Home Improvements Builds
Detached ADUs (DADUs)
Detached accessory dwelling units are standalone structures built separately from the main residence. Often referred to as backyard cottages, granny flats, or Casitas, these units provide the greatest level of privacy and flexibility.
Garage Conversions
As an experienced garage conversion contractor, AAA Home Improvements converts existing garages into fully functional living spaces. Many garage conversions require structural upgrades to meet code requirements, including foundation reinforcement, insulation improvements, and ceiling height modifications.
Above-Garage ADUs
These over-garage living spaces maximize unused vertical space while preserving parking or storage below. They are particularly useful for properties with limited lot space.
Basement ADUs
Many homes throughout Denver include sizable basement areas that can be transformed into accessory dwelling units. Basement conversions are often one of the more cost-effective ADU solutions available.
Attached or Internal ADUs
Attached ADUs create a separate living space within or connected to the primary home structure. These projects are commonly used for multigenerational housing or private in-law suites.
Each project type involves different considerations related to zoning, setbacks, utilities, and structural engineering. AAA Home Improvements evaluates these factors during the early feasibility stage.
Their 6-Step ADU Process
AAA Home Improvements follows a structured process designed to keep projects organized and homeowners informed throughout construction.
Virtual Consultation
The process begins with a video consultation where homeowners discuss goals, budget, timeline, and project ideas with the company’s estimator.
Site Assessment
An on-site evaluation is performed to review lot conditions, zoning restrictions, setbacks, utility access, and structural feasibility.
Design and 3D Renderings
Architectural plans and 3D visualizations are created to help homeowners understand the proposed layout and request adjustments before construction begins.
Engineering and Permitting
Structural engineering plans and permit applications are prepared and submitted to local municipalities. AAA Home Improvements manages city coordination and permitting on behalf of the homeowner.
Construction
During construction, the company coordinates subcontractors, inspections, scheduling, and material deliveries while providing regular progress updates.
Final Walkthrough and Handover
Once construction is complete, the team performs a detailed walkthrough, addresses any remaining punch-list items, and provides warranty and maintenance information.
