An Accessory Dwelling Unit (ADU) is a secondary, self-contained home located on the same lot as a primary residence. It includes its own kitchen, bathroom, sleeping area, and separate entrance. They are also commonly known as granny flats, in-law units, or backyard cottages.

We specialize in new, detached, custom stick-built ADUs that are completely tailored to your property and design vision. This allows for maximum flexibility in size, layout, and finish, unlike pre-fabricated or modular options.

Yes, absolutely. We offer a complete, turnkey solution. Our team handles every aspect of the project, including necessary site work (grading, utility trenches, foundation), coordinating all utility connections, and landscaping. We begin with a site consultation to provide an accurate estimate for all site preparation.

Yes, a building permit is typically required for any new residential structure. Local zoning regulations dictate the specifics, but our team manages the entire permitting process, from architectural submission to final inspection. We will pull all necessary permits for your unit. We also offer several smaller models that may not need a permit.

Most California cities allow ADUs in residential zones, but specific requirements for height, setbacks, and size can vary by municipality and lot size. We offer assistance in helping you navigate and figure out these local zoning codes to ensure your project is fully compliant.

Costs vary widely as our units are custom-built, depending on size, location, complexity of the site work, and the level of interior finishes selected. Your budget should generally include permits, construction, utility hook-ups, and potential site preparation. We provide a transparent, detailed estimate after the initial design and site consultation.

Yes. Various financing options exist, including home equity loans (HELOCs), construction loans, and specialized ADU financing programs offered by some local and national lenders. We work with renofi an amazing lender for construction projects with the best rates in the state.

Building an ADU will increase your property taxes, but the increase will be based only on the assessed value of the new construction. It will not trigger a full property reassessment of your primary residence, which helps keep the increase proportional.

Yes. ADUs are a fantastic source of rental income. They can generally be rented out, but it's important to check local city/county regulations regarding short-term rentals (like Airbnb) versus long-term leases (30+ days).

Unlike modular builders who rely on fixed templates, our stick-built process allows us to fully customize the floor plan, window placement (perfect for maximizing light and views), exterior materials, and interior finishes to match your exact needs, aesthetic preferences, and the unique constraints of your property.

Our custom ADUs are designed to meet or exceed California's strict energy efficiency standards. We focus on sustainable building practices, insulation, high-efficiency systems, and material selection to deliver a unit that is both eco-friendly and keeps long-term utility costs low.
