Frequently Asked Questions
Have a plan or design in mind? Our 3D renderings can show you what it looks like in reality. Our team has deep experience in bringing our clients’ ADU wishes to life. Whether it’s a new ADU addition, conversion, or detached construction, we are here to help.
The timeline for your ADU project can vary based on factors like the size, complexity, and permitting process. On average, our projects are completed very quickly once permits are approved - most construction is fully completed within 8-10 weeks. We'll work closely with you to develop a schedule that works for your needs.
Permitting requirements vary depending on the specific location and type of ADU. However, several local jurisdictions now offer "pre-approved" ADU building plans, which greatly cuts down on planning costs and time. Our experienced team is well-versed in local regulations and will guide you through the permitting process to ensure compliance with all relevant codes and zoning requirements.
We understand that financing your ADU project is an important consideration. We work with several local community banks and lenders who offer financing for ADU additions and new construction. Give us a call for a referral, and we'll work with you to make the process as smooth as possible.
Yes- this was one of the significant changes in the recent updates to Washington's ADU laws. Some clients are able to "condo" their ADU and/or DADU once built, enabling them to sell the ADU or DADU separately from their main home. Call us to find out more.
We offer both options. If you have your own ADU building plans, we can bring them to life. Alternatively, we provide full-service in-house ADU design and construction. Our design team will collaborate with you to create a custom design that matches your vision and goals.
