Here’s the complete timeline and insider knowledge you won’t find anywhere else.

ADU Considerations
The pricing:
- Materials Budget: wide range depending on your choices
- Labor
- Foundation Work
- Utility connections
- Survey and design fees
- Multiple permit fees
Other Considerations
- Traditional stick-built tends toward the higher end
- Modular/prefab solutions can significantly reduce costs
Why Modular Makes Sense
After going through this process, here’s why modular is the smart choice:
- Speed: Factory construction happens while permits are processing – no weather delays
- Efficiency: Precise manufacturing reduces waste and ensures consistent quality
- Sustainability: Better insulation, energy efficiency, and sustainable materials standard
Predictable Costs: Less risk of cost overruns during construction
