Common questions
What is the best accessory dwelling unit?
The 'best' ADU is one tailored to your specific Colorado property and lifestyle. It should be functional, aesthetically pleasing, and energy-efficient for the climate. We assess your needs in Arvada, Westminster, or Centennial to recommend the ideal solution.
What does ADU stand for?
ADU stands for Accessory Dwelling Unit. These are secondary, independent living spaces on a single-family home lot. They provide homeowners valuable flexibility, such as rental income or accommodating family members.
How big can an ADU be in Oregon?
In Oregon, the maximum size for an ADU is generally tied to the size of the primary dwelling and lot. Many jurisdictions allow ADUs up to 800 square feet, but specific regulations can differ. It's essential to consult local planning departments for precise measurements applicable to your property.
What are the downsides of ADUs?
Potential downsides include increased utility usage for the property, potential impacts on neighborhood character if not well-designed, and the initial investment cost. Careful planning and design can mitigate these concerns. We focus on creating ADUs that enhance, not detract from, your property.
What is the cheapest way to build an ADU?
The most cost-effective approach often involves utilizing existing structures like garages or basements. Prefabricated or modular ADUs can also offer savings through factory efficiencies. We can help you explore options that balance cost and quality for your Colorado build.
How does Colorado's climate affect ADU construction?
Colorado's altitude and temperature swings require superior insulation and robust HVAC systems. Designs must account for potential snow loads and high UV exposure. Our ADUs are built for year-round comfort and durability in this environment.
