In Irvine, the service we provide for accessory dwelling units (ADUs) is often confused with other types of home improvement projects, but our focus is strictly on the design, permitting, and construction of secondary, independent living units. With a density of 4795 people per square mile, Irvine is a meticulously planned city where ADUs must integrate seamlessly with existing residential architecture and adhere to strict development standards. Our licensed, insured professionals understand the nuances of Irvine's zoning ordinances, including requirements for lot coverage, setbacks, and parking, ensuring your ADU project is fully compliant. We meticulously detail the construction process, from site preparation and foundation work, often involving engineered concrete slabs suitable for Southern California's seismic considerations, to the framing using advanced wood or steel systems. The selection of high-performance, low-VOC materials for insulation, drywall, and finishes is standard, aligning with Irvine's commitment to sustainability and healthy living environments. We also manage the installation of all necessary utility connections, ensuring efficient integration with existing infrastructure. Our objective is to provide a clear, technically precise roadmap for your ADU construction, demystifying the process and ensuring a high-quality outcome that enhances your property's value and utility within the Irvine community. We clarify the technical specifications so you can budget effectively.

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.

About this service

A backyard ADU is a detached small home built on your property, separate from your main house. People typically build these to create extra living space for family members, as a private home office, or to gain additional rental income. Because they are freestanding, you will need to consider utility hookups, site access for crews, and local setback requirements. Costs vary based on the foundation type and utility connections. Exact pricing confirmed free on the call.
