About 3R Services

ADU Construction Services by 3R Services in Arvada, CO

For families in Arvada looking to add flexible living space or generate rental income, an accessory dwelling unit (ADU) can be a practical solution. 3R Services is an ADU contractor based in the area, offering construction services for a range of ADU types — from detached backyard cottages and garage conversions to attached guest suites and custom units. Founded by the Cressman family and with over 25 years in business, the company focuses on transparent pricing and clear communication throughout each project.

Their ADU builds are suited for homeowners who want to house family members, create an in-law suite, or add a rentable unit without relocating. 3R Services uses a cost-plus pricing model, providing itemized estimates that outline scope, materials, and costs. ADU project costs in Arvada typically range from $80,000 to $250,000, depending on size and features.

How 3R Services Manages the ADU Build Process

The process begins with a site visit to the homeowner's property. Led by owner Jim Cressman, the team reviews the site, discusses the homeowner's goals, and assesses local zoning requirements. This initial step helps shape a plan that fits both the property and the family's needs.

From there, 3R Services prepares a detailed bid before any work begins. Once approved, they handle the permitting process — coordinating with architects and engineers where needed — and establish a clear project timeline. Arvada's zoning regulations do permit ADUs, and recent legislation has in many cases overridden HOA restrictions. 3R Services manages compliance with these local rules as part of their service.

During construction, a field operations leader oversees subcontractors to maintain quality and scheduling. Homeowners receive real-time updates through a group text thread, keeping them informed without requiring constant involvement. Most Arvada ADU projects are completed within 3 to 6 months, depending on scope.

At project completion, a final walkthrough is conducted to confirm the work meets the agreed-upon specifications. 3R Services also provides a one-year workmanship warranty on their ADU builds.

ADU Types and Benefits for Arvada Homeowners

3R Services builds several types of ADUs, including:

  1. Detached backyard cottages and granny flats
  2. Garage conversion ADUs
  3. Attached guest suites and in-law suites
  4. Junior ADUs (JADUs)
  5. Custom accessory dwelling units

Adding an ADU can serve multiple purposes — providing space for aging relatives, offering a rentable unit to offset mortgage costs, or simply expanding the functional footprint of a home. In Arvada's growing housing market, an ADU can also contribute to increased property value.

3R Services positions itself as a local ADU builder familiar with Arvada's permitting requirements and neighborhood considerations. Their approach emphasizes keeping disruption to a minimum during construction and maintaining budget alignment through transparent bidding — factors that matter to homeowners managing busy family schedules.

For those considering an accessory dwelling unit in Arvada, 3R Services handles the full scope of the project, from initial planning and permitting through to final construction and warranty support.
