Frequently Asked Questions
What is an ADU?
An ADU, or accessory dwelling unit, is a secondary living space on the same property as a primary home. It can be attached to the main house, located inside the home, or built as a separate structure.
What is a DADU?
A DADU, or detached accessory dwelling unit, is a separate standalone living space built on the same property as the main home. It may be used for family, guests, rental income, or flexible living space.
What are the Benefits of ADUs?
Do ADUs Have Design Considerations?
Yes, both ADU and DADU must comply with local regulations concerning size, location, and amenities. We will inform you of these during our consultation phase. Aside from regulations, you can add design features that meet your preferences, which our in-house interior designer can help you plan.

Can I Convert a Garage into an ADU?
Yes, a garage can often be converted into an ADU if it meets Whatcom County building codes, zoning rules, ceiling height requirements, insulation standards, utility needs, and safety requirements. See if your Whatcom County property is eligible to build an ADU here.
Can I Build a DADU in My Backyard?
A backyard DADU may be possible if the property meets local requirements for lot size, setbacks, access, utilities, height limits, and parking. Our team will assist you with the permitting process to make sure your project is compliant.
What Should I Consider Before Building an ADU or DADU?
Consider how the space will be used, who will live there, privacy, accessibility, storage, parking, utilities, outdoor access, budget, and long-term flexibility. At Casali Construction & Remodeling we can help walk you through the process and help get your project compliant for building.
Are ADUs Good for Multigenerational Living?
Yes. ADUs and DADUs are convenient for multigenerational living because they allow family members to live nearby while maintaining privacy and independence.
Does an ADU Add Value to a Home?
An ADU can add value by increasing usable living space and potential rental income. The actual value depends on local demand, and how the space is permitted and used. We will help you consider how to maximize your property value by adding a new ADU or DADU.
How do I Start Planning an ADU or DADU?
Start by identifying how you want to use the space, set a budget, and then contact Casali Construction & Remodeling. We’ll help handle the permitting and design requirements so we can build your new ADU or DADU, bringing your vision to reality.
