A design build ADU company provides both architectural design and construction services under a single contract. This integrated approach streamlines the entire process of adding an accessory dwelling unit, from initial concept and permits to final construction. Instead of hiring separate architects and contractors, you work with one team that manages all aspects. This model reduces miscommunication and often speeds up project timelines. For homeowners in San Jose, this can be particularly valuable when navigating local zoning laws. For more details on how this approach applies to older properties, see our internal article titled Historic Home Remodeling In San Jose: Preserving Charm, Adding Comfort.

Yes, in California, it is generally possible to build an Accessory Dwelling Unit (ADU) before the main house, but specific local rules apply. In cities like San Jose, Santa Clara, and Sunnyvale, you may construct an ADU on a lot that already has a primary dwelling or is planned to have one. However, the ADU must be built in conjunction with a new primary residence, or the existing home must remain on the property. For detailed guidance on this process, including zoning and permitting, we recommend reviewing our internal article titled ADU Designing and Planning. Lecut Construction advises consulting with local planning departments to confirm requirements, as regulations can vary by jurisdiction within the service area.
In San Jose, the maximum size of an attached Accessory Dwelling Unit (ADU) depends on the lot size. For lots of less than one-half acre, the ADU cannot exceed 1,000 square feet. For lots of one-half acre or larger, the maximum size increases to 1,200 square feet. Additionally, the ADU must not exceed 50 percent of the existing primary dwelling's floor area. These regulations are designed to balance housing density with neighborhood character.
