5 Essential ADU Steps
Carson Custom Homes is committed to delivering outstanding customer service and exceptional results through our ADU process, which comprises 5 essential steps:
Assessment
We initiate the process by conducting a comprehensive assessment of your property to determine the feasibility of constructing an Accessory Dwelling Unit (ADU). Our design team evaluates current land and zoning regulations to ensure compliance and viability.
Design
During this phase, our skilled design team creates detailed CAD drawings that outline the proposed ADU, including precise measurements and specifications. This enables you to visualize how your property will appear upon completion.
Permits
Following the design phase, our team takes on the responsibility of securing all necessary construction permits. This phase may require patience due to the various permits required for ADU construction.
Construction
We enlist only the most experienced tradesmen who specialize in their respective fields to ensure efficiency without compromising quality. Throughout the construction process, our goal is to bring your vision to life while adhering to the highest standards. You approve the work at each phase of your project to ensure everything is up to your standards.
Finish
Once construction is finished, our team completes the ADU with all essential features, including electrical wiring, plumbing, HVAC systems, flooring, and more. This ensures that your ADU meets all local and state building codes and regulations.
