Room Addition & ADU Construction in San Jose — Expand Your Living Space

Room Additions / ADU

We’re helping completely transform your living spaces. Not sure which is best for you, an add-on, or an ADU? Let’s break it down.

We build ADU Construction in San Jose, also known as In-Law Units, from start to finish. Our team will assist with everything from blueprints to construction. ADUs are similar to having an additional home on the same property that can provide extra income or extra living space for your family.

They are fully equipped with a living area, kitchen, bathroom, and private entrance. Our Accessory Dwelling Units can be attached to your home, or we can build a stand-alone, depending on what works best for you and on site restrictions.

NuHome Room Addition in San Jose gives you the extra space you need to accommodate a growing family, provide more privacy within the home, or create more living areas without moving to a new home.

Regardless of which type of add-on works best for your home, we’re here to work with you from start to finish.

Scope of work

What’s in an addition or ADU?

Ten stages, one contract, one project manager. Ground-up work lives or dies on the permit set — so that is where we start.

Get your scope priced
  1. Feasibility & design

    What your lot, setbacks and city will actually allow, turned into a design that fits the existing house.

  2. Plans & engineering

    Structural drawings and Title 24 energy calculations prepared for submission.

  3. Permits & plan check

    Applications to your city or county, plan check corrections and approvals, handled by NuHome.

  4. Foundation

    Footings and a slab or raised floor, inspected before anything goes up.

  5. Framing & roof

    Structure, roof framing and tie-ins to the existing building.

  6. Windows, doors & envelope

    Weatherproofing, insulation, siding or stucco, so the new work matches the old.

  7. Electrical, plumbing & HVAC

    Full systems for the new space, including the bathroom and kitchen of an ADU.

  8. Interior finishes

    Drywall, floors, cabinetry and the fit-out that makes it liveable.

  9. Utility connections

    Sewer, water, gas and panel upgrades where the new space requires them.

  10. Inspections & final clean

    Final sign-off, then our cleaning crew before handover.
