Key Cost Factors
- Permits and Fees: Expect to pay $5,000 – $15,000+ for permits alone. These costs vary depending on local regulations and the scope of your project.
- Site Preparation and Foundation: This critical phase can range from $20,000 – $45,000+, influenced by soil conditions, grading, and the type of foundation required.
- ADU Type and Size: Garage conversions are often the most budget-friendly option, while detached, larger ADUs (like a two-bedroom unit) will naturally incur higher costs. A 525 sq ft junior ADU, for example, could cost roughly $140,000 all-inclusive.
- Material and Finish Quality: The choice between standard, good quality, or high-end materials can significantly impact the overall price. High-end finishes and custom designs push costs towards the premium tier.
