Many people confuse a full-scale home addition with an accessory dwelling unit (ADU) project in San Diego, California, but the scope and zoning regulations are entirely different. An ADU, often referred to as a granny flat or in-law suite, is a secondary housing unit on an existing single-family lot. These units are specifically designed to provide independent living quarters for family members, tenants, or caregivers, and their construction adheres to strict California state laws and San Diego Municipal Code requirements. Understanding these nuances is critical before you even begin to consider design or materials. The process involves detailed architectural plans, structural engineering, and navigating the complex permitting pathway with the City of San Diego Planning Department. Our licensed, insured pros understand these specific requirements, ensuring your project moves forward efficiently. This thorough approach minimizes delays and potential costly revisions. The goal is to create a functional, legally compliant living space that adds value to your property. We make the process straightforward, from initial consultation to final inspection. Don't let confusion about ADU regulations in San Diego slow you down. Call now for clarity and a precise estimate.

What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.
