AccessoryDwelling Units
Next Stage Design + Build builds accessory dwelling units throughout Santa Clara County, including detached ADUs, attached suites, garage conversions, and junior ADUs (JADUs). California state law has significantly reduced barriers to ADU construction since 2016, but the permit process still involves multiple city departments and site-specific zoning requirements.

Frequently Asked Questions About Design + Build Remodeling
How much does a remodeling project cost?
Remodeling costs in Silicon Valley depend on the service type, scope, and material selections. Bathroom remodels typically range from $40,000 to $150,000 or more. Kitchen remodels range from the mid-five figures to well over six figures. Home additions and ADUs range from $100,000 for a garage conversion to $500,000 or more for detached new construction. Whole-house remodels start in the several hundred thousands and can exceed one million dollars depending on home size and scope. These ranges reflect current Santa Clara County labor and material costs. The only accurate way to estimate your specific project is a consultation based on your home and goals.
What is a fixed-price contract and what does it cover?
A fixed-price contract specifies the complete scope of work, total project cost, payment schedule, and confirmed start and completion dates before any work begins. At Next Stage, all selected materials, design services, 3D renderings, and project management are included in the contract. The only items budgeted as allowances are paint, drywall patching, and permits, which are estimated upfront and finalized once those specific phases are completed. Everything else is locked in before demolition begins.
Do you handle permits?
Yes. Next Stage manages the full permitting process for every project, including plan preparation, submission to the local building and planning departments, plan check responses, permit issuance, and all required construction inspections. We have direct experience with building departments across Santa Clara County and manage the entire process on behalf of every client.
How long does a project take?
Timeline depends on scope and project type. Bathroom remodels typically span two to four months from initial consultation through completion. Kitchen remodels typically run several months. Home additions and ADUs typically span six months to over a year depending on structural complexity and the permitting timeline for that specific city. Whole-house remodels run six months to over a year. We set project-specific timelines at the start of every engagement and track them daily through our BuilderTrend client portal.
What is the advantage of working with a design-build firm?
With a design-build firm, one company manages design, permitting, and construction under a single contract. There is no gap between what gets designed and what gets built, because the designer and the construction team are not two separate businesses with separate priorities. This means more accurate budgets, fewer change orders, and a finished result that reflects the 3D rendering approved before work began. Next Stage maintains a 6 percent change order rate, well below the industry average, reflecting how thoroughly each project is planned before work begins.
Is design included in the price?
Yes. Space planning, 3D renderings, material selections, and all drawings needed for permitting are fully included in the Next Stage fixed-price contract. There are no separate hourly design fees at any stage of the project.
What credentials does Next Stage hold?
Yes. Next Stage is a fully licensed general contractor (License #850885), employee-owned, and holds business licenses in every city in Santa Clara County. Our corporate insurance includes Workers' Compensation, General, Professional, Pollution, and Automotive liability coverage. Every completed project is backed by our 2/4/10 warranty: two years on labor and subcontractor work, four years of support with manufacturer warranties, and ten years for latent structural defects.
What warranty covers my project?
Every Next Stage project is backed by a 2/4/10 warranty: two years on labor and subcontractor workmanship, four years of assistance navigating manufacturer warranties on appliances, fixtures, and installed products, and ten years on latent defects in construction or structural workmanship. The standard industry warranty on workmanship is one year. Next Stage's is double that minimum.
