ADUs made simple, beautiful, and affordable — right here in Montana
Accessory Dwelling Units add flexible space for family, guests, or rental income. Think: long term rental, studio/office, or multigenerational living. We handle feasibility, conceptual design and planning, and coordination with your city so your ADU is designed to meet local standards and fit your lot.
Zoning and Setbacks:
We design to local requirements; final approvals are made by your jurisdiction
The Process:
Step 1: Give us a call or fill out the box below
We will discuss goals, budget, and property details
Step 2: Site visit and Feasibility
Jason will meet you on site to determine access, grades, utilities and setbacks.
Step 3: Design + Retainer
Madison will work with you to create conceptual floor plans, elevations, and sections. Retainer fee ($2500) will be applied to your build. Engineer and/or Architect may still be necessary depending on the complexity of your project
Step 4: Plans and Permits
Together we submit your plan set (if required and/or desired. Not all zones require permitting), coordinate with city/county and utilities. We will be with you every step of the way as this process can often be complex
Step 5: Sign Contract + Start Build
We require a signed contract and 50% deposit to start your project. Once those are satisfied, we can usually break ground immediately
