Step 1: Feasibility & Planning

Add a fully detached home to your property.

Detached Accessory Dwelling Units (DADUs) are one of the most powerful ways to add long term value, rental income, or flexible living space to your Seattle property. Whether you're building for aging parents, tenants, grown kids, or future resale appeal, a well designed DADU opens the door to new possibilities.

We start by helping you determine what’s actually possible on your lot. Seattle’s zoning, setbacks, and size requirements for DADUs can be tricky, so we begin with a feasibility study, site measurements, and a basic design consultation.

If you're already working with an architect, we’ll review early plans together. Starting from scratch? We can help you adapt a pre-approved plan or collaborate on something custom. We’re happy to take the lead on design, or connect you with top-notch professionals. If you’ve got your own designer in mind, we’ll gladly work with them too.

Our goal is simple: get you through permitting with as few headaches as possible.

Step 2: Permitting & Pre-Construction

Design and Build
Once the design is dialed in, we coordinate structural engineering, surveying, and permit submittals and make sure your DADU meets Seattle’s building codes and ADU requirements. We'll walk you through construction pricing, select key finishes, and build out a clear budget and schedule. By the time we break ground, you’ll know exactly what to expect.

Step 3: Build + Completion

Time to swing a hammer

From excavation to final inspection, we manage the entire construction process. We handle excavation, foundation, framing, mechanicals, and all finish work. We keep your neighbors happy, the site clean, and you informed every step of the way. I like to maintain excellent communication with my clients, so I’ll be available to you for regular meetings, status updates. When my phone rings and you’re calling, I answer. When it’s done, your new DADU is fully legal, code-compliant, and ready for renters, guests, or extended family.
