ADU & Ohana Unit Permit Drafting

Get DPP-Compliant Drawings for Your ADU or Ohana Unit Project

Planning to build an ADU (Accessory Dwelling Unit) or Ohana unit on your property? Before you can break ground, you’ll need a complete set of drawings that meet Honolulu’s building codes and zoning rules. These drawings are required to apply for permits through the Department of Planning and Permitting (DPP). Home Planning Hawaii helps homeowners get accurate, professional drawings made just for ADU and Ohana unit construction—so you can move forward with confidence.

What Is ADU & Ohana Unit Permit Drafting?

It’s the process of creating technical plans that show how your new unit will be built. These plans must follow specific DPP guidelines for size, location, use, and access.

The Drawing Set Usually Includes:

  • Site plan with setbacks and access paths
  • Floor plans and layout of the new unit
  • Roof, foundation, and elevation views
  • Electrical and plumbing layout
  • Notes that show compliance with ADU or Ohana rules
Why These Drawings Are Important

You Need Them for a Permit

No ADU or Ohana unit can be legally built without approved drawings.

They Must Follow Specific Honolulu Rules

The City has different rules for ADUs and Ohana units—including size, parking, and access. The drawings must reflect those

Good Drawings Help Projects Move Faster

Clear, correct drawings reduce permit delays and give your builder everything needed to get started.
