Attached ADUs integrate new living space directly into your existing home's structure, often through a garage conversion or an addition. This approach maximizes your property's footprint while providing a fully independent dwelling unit.
A detached ADU from Mighty ADU Company provides a completely separate living space on your property, including its own foundation, framing, utilities, and finishes. This creates a distinct, private residence ideal for rental income, multi-generational living, or a dedicated home office.
Our garage conversion service transforms your existing garage into a fully functional living space, including structural modifications, utility extensions, and interior finishing. This creates valuable square footage for a new bedroom, home office, or rental unit, enhancing your property's utility and value.
ADU Permitting involves navigating Campbell's specific building codes and zoning ordinances to secure approval for your accessory dwelling unit project. We manage the entire submission process, ensuring your plans meet all regulatory requirements for a compliant build.
ADU design from Mighty ADU Company includes architectural plans, structural engineering, and utility schematics to ensure a buildable and code-compliant accessory dwelling unit. This detailed planning phase prevents costly changes during construction and optimizes your ADU's functionality and aesthetic integration.
ADU engineering involves the structural and civil design calculations necessary to ensure your accessory dwelling unit is safe, compliant, and buildable. This critical phase provides the detailed construction documents required for permitting and a sound foundation for your build.
Choosing Mighty ADU Company means partnering with builders who understand Cupertino's specific context. We're not just contractors; we're problem-solvers familiar with local conditions, from soil types to the specific permitting nuances often encountered with the City of Cupertino Planning Department. This local knowledge helps us anticipate challenges and streamline the construction process, minimizing delays and ensuring your project adheres to all municipal guidelines.
Our construction methodology prioritizes structural integrity and long-term performance. For instance, we typically specify a minimum of 4,000 PSI concrete for foundations, reinforced with #4 rebar on 12-inch centers, which provides superior load-bearing capacity and resistance to seismic activity. We also employ advanced framing techniques, such as optimal value engineering (OVE) framing, to reduce material waste and improve thermal performance, which means lower energy costs for the ADU occupant. We don't just build; we engineer for durability and efficiency.
When you work with us, expect a structured process that keeps you informed. We begin with a detailed site assessment, followed by architectural design that considers your property's specific setbacks and utility connections. Our project management includes regular progress updates, detailed scheduling, and meticulous coordination with all trades, from framing to finish carpentry. We manage all inspections and ensure every phase passes stringent quality checks before moving to the next, delivering a finished product that stands up to scrutiny and serves its purpose for decades.
ADU size restrictions in Cupertino generally allow for a maximum of 1,200 square feet for a detached ADU or 50% of the existing primary dwelling's floor area, whichever is less, but not less than 850 square feet for a one-bedroom or 1,000 square feet for two or more bedrooms. For attached ADUs, the maximum size is typically 50% of the existing primary dwelling's floor area or 1,200 square feet, whichever is less. These limits are subject to specific lot size, setback requirements, and current city ordinances, which we meticulously verify during the initial design phase to ensure full compliance with the City of Cupertino's Municipal Code.
The ADU permitting process in Cupertino can typically take anywhere from 3 to 6 months from initial submission to permit issuance, depending on the completeness of the plans and the volume of applications at the City of Cupertino's Planning and Building Departments. This timeline includes plan check reviews, potential revisions, and coordination with various city departments like Public Works for utility connections. We meticulously prepare all necessary documentation, including detailed architectural drawings, structural calculations, and energy efficiency reports, to minimize review cycles and expedite approval.
Common utility connection requirements for a new ADU in Cupertino often involve separate electrical sub-panels, new or upgraded water lines, and sanitary sewer connections to the existing main or a new lateral. Depending on the ADU's location relative to the primary residence and existing infrastructure, trenching may be required for new lines, and sometimes an upgrade to the main electrical service panel is necessary to accommodate the increased load. We conduct a thorough site survey to assess existing utility capacities and plan for all necessary upgrades or new connections, ensuring compliance with PG&E, Santa Clara Valley Water District, and Cupertino's Public Works standards.
