From Plan to ADU

Whether you're just beginning to explore the idea of an ADU or you're ready to build, we're here to guide you through every step of the journey.

Dwelly ADU plan and home study

I think I want an ADU. Now what?

The path from a first idea to a completed ADU has decisions, approvals, drawings, budgeting, and construction. This page walks through the whole journey in the order most homeowners experience it.

Step One

Imagine What's Possible

Before choosing a plan, think about what you want your ADU to do.

Most homeowners identify with several life chapters. Dwelly plans are intentionally adaptable and can evolve as your life changes. If Aging in Place is one of your primary goals, we generally recommend beginning with a single-level design for long-term accessibility.

Step Three

Planning Package

The Planning Package helps you move from a promising idea into a grounded plan for your property, budget, and local approval path.

  • Understand local zoning
  • Prepare for building department conversations
  • Review utilities and access
  • Understand setbacks and site constraints
  • Begin realistic budgeting
  • Share drawings for contractor pricing
  • Gain confidence before moving forward

The Planning Package includes the Dwelly Planning Checklist, which walks homeowners through each planning milestone from idea to build.

Step Four

Build Package

Once planning is complete, the Build Package gives your local team the construction documentation needed to move toward permitting and pricing.

  • Detailed construction drawings based on your selected Dwelly plan
  • Supporting documentation for your local building department and project team
  • A Project Information Sheet to adapt the plans to your specific property
  • A kickoff meeting with your contractor before construction begins
Every property and jurisdiction is different. If your local building department requires additional modifications beyond the standard Build Package, Dwelly can provide custom plan revisions and consulting on an hourly basis.

Step Five

Permitting & Construction

With the right plan and package in place, the final preparation is about coordination: permits, contractors, kickoff, and construction support.

  • Prepare your permit submission
  • Coordinate with your contractor
  • Hold the kickoff meeting
  • Move into construction with support

This phase can feel technical, but it should not feel mysterious. Dwelly helps you understand what is happening, who is responsible, and what comes next.

Step Six

One Home. Many Chapters.

An ADU is not designed for just one season of life. A thoughtful Dwelly plan can start as a workspace, become a guest house, support care, and later create income.
