What goes in the package
A complete DADU residential permit submittal includes:
- Cover sheet with project information
- Site plan (from the survey + DADU footprint + setbacks called out)
- Floor plans + elevations + sections
- Structural plans + calculations (engineer-stamped)
- Energy compliance worksheet (REScheck or performance model)
- Stormwater plan + calcs
- MEP plans
- Tree report or arborist plan if Title 11 applies
- Pre-app meeting notes if you had one
How submittal works
- Log into DevHub.
- Start a new "Residential Permit" application.
- Upload all documents as PDFs (sized correctly — DevHub rejects oversized files).
- Pay the plan check fee at submittal (typically $1,200-$2,500 for a DADU).
- PP&D's intake team reviews for completeness within 1-2 weeks. They'll either accept it into review or kick it back with a list of missing items.
What happens after intake
The application goes to multiple disciplines in parallel: planning, structural, residential, plumbing, electrical, mechanical, BES, and (if triggered) Urban Forestry. Each has its own queue.
