        "text": "The total investment for an ADU is driven by square footage, foundation type, utility infrastructure, and interior finish choices. Because an ADU functions as a complete independent home, it requires dedicated plumbing, water heating, an electrical subpanel, and kitchen appliances, making it more cost-intensive per square foot than an open bedroom addition. Connecting water, sewer, and electric services from the primary house or street across the property also represents a meaningful portion of the budget. Customizations like curbless walk-in showers, specialized cabinetry, and exterior stucco finishes also affect the final estimate.",
