Why Choose This ADU Plan Set

Opting for a pre-designed ADU plan is a cost-effective and accessible solution for various income levels, offering top-notch designs at a reduced cost. This particular ADU is ideal for use as a rental, Airbnb, or guest house, offering an easy and budget-friendly construction process. Its small size allows it to easily fit in most backyards.

While a tailor-made ADU could consume around 10% of your total budget, usually ranging from $10,000 to $30,000, choosing a pre-made plan can lead to substantial savings. Furthermore, these plans also expedite the process, as most of the design phase has already been completed, saving you valuable time.

What's Included with Your ADU Plan Purchase?

When you buy an ADU plan, you receive a downloadable ZIP file. This file contains a PDF of your chosen design and Source files for detailed viewing. The included drawing set comprises:

  • Cover Sheet: Shows a perspective image of the ADU design and the title block.
  • Notes, Terms & Conditions: Outlines the usage terms of these drawings.
  • Legends, Schedules, and Standards: Contains all notations, abbreviations, and definitions used in the drawings, along with schedules for doors, windows, and rooms.

What else you will need

Each property/lot is distinct, with varying local laws and regulations. It's crucial to verify that the design you select complies with the rules applicable to your property. You might also need to consult with structural engineers or other specialists to fulfill local regulatory demands. Furthermore, we suggest enlisting the services of a local designer, architect, engineer, or general contractor. They can aid in navigating the permitting process and making any necessary modifications to secure permit approval.
