Our construction approach focuses on strong structural integrity and good energy efficiency. An ADU is a long-term investment for any San Jose homeowner. We use materials like advanced framing lumber, which means 2x6 walls at 24 inches on center, for better insulation. We also use high-performance windows with a low U-factor. The U-factor shows how well a window will keep heat in or out. This significantly lowers heating and cooling costs for your San Jose ADU. For foundations, we usually pour a reinforced concrete slab on grade. This includes a vapor barrier and proper drainage to stop moisture from getting in, because San Jose's soil conditions can be different in various areas. Every detail, from the electrical panel sizing to the plumbing rough-ins, is done to meet or go beyond current California Building Code standards.

The final size of an ADU can change based on the specific lot size, existing setbacks, and the number of bedrooms on the property. This means a detailed site analysis is important for any ADU project in San Jose. Junior ADUs, also called JADUs, are limited to 500 square feet.

No, San Jose usually does not require extra parking for ADUs in many situations. This includes when the ADU is within a half-mile walk of public transit. It also includes ADUs that are inside an historic district. Another situation is when a car share vehicle is located within one block of the ADU. If your property does not meet these exemptions for ADU parking in San Jose, then one extra off-street parking space is typically required. This parking space can be in a tandem driveway or we can find other solutions for your San Jose ADU. We will look at your property's specific ADU parking needs during our first consultation for your San Jose ADU project.
