Factors Affecting ADU Costs

Understanding the various factors that impact the cost of building an ADU is crucial for budgeting purposes. Here are some key considerations:

Size and Layout

The size and complexity of your ADU will greatly influence the overall cost. Larger units and intricate designs tend to be more expensive due to increased material and labor requirements.

Materials and Finishes

The choice of materials and finishes, from flooring to fixtures, can vary widely in price. High-end materials will naturally increase the overall cost but can also enhance the durability and aesthetic appeal of the unit.

Permit and Zoning Fees

In San Jose, permit and zoning application fees typically range from $200 to $400. However, additional fees may apply depending on the size and specific requirements of your ADU project. Utilizing the city's Permit Cost Estimate Worksheet can provide a more accurate assessment.
