Our Process

Let Otto handle planning, design, and permitting.
After you get permits, you can opt in for our hassle-free construction and project management service for peace of mind from start to finish.

Phase 1 / 4


In-person Site Inspection

Otto visits your property and analyzes its ADU potential. We identify various conditions (such as utility runs, grading requirements, and structural issues) that could impact cost.

Virtual Design Session

A Designer creates plan options that fit your space. Your Project Planner gathers your feedback and helps you select finishes and fixtures from our Design Decision Catalog. Transparent pricing makes it easy to lock in all of your project decisions.


When your design decisions are complete, Otto will provide you with a contract to move to Phase 2, and apply your deposit towards the next step!

What you get:

  • Site Inspection Report
  • Pricing Estimate
  • Comprehensive Scope of Work
  • Design Plan Incorporating all Design Decisions
  • Deposit Applied toward Phase 2
