The first step in building an ADU in Bellingham is understanding what is possible on your property. Zoning, owner occupancy rules, site constraints, utilities, and access all need to be considered.

If you’re just starting out, we offer a complimentary ADU Assessment for your lot. We review zoning and site requirements and evaluate feasibility from a construction perspective to ensure your ideas can realistically be built. We then connect you with designers and architects to get started on the planning process.

If you already have a conceptual design or plans, we will provide a detailed proposal to give you a clear picture of what moving forward will look like.

In either case, we work closely with your designer or architect to keep the project on track and on budget from start to finish.​
