How much does a full home renovation cost in San Jose?

Whole-home renovations in San Jose cost $100 to $300 per square foot depending on scope and finishes. A 1,500 square foot home renovation with mid-range finishes costs $150,000 to $350,000. High-end full renovations with complete kitchen and bathroom overhauls, new flooring, windows, and exterior work can exceed $500,000. Quartz Construction provides detailed scope-based estimates.

How long does a full home renovation take?

Whole-home renovations in San Jose typically take 4 to 9 months depending on scope. Permit approvals take 4 to 8 weeks. Cosmetic renovations take 2 to 3 months to construct. Structural renovations with kitchen, bathroom, and layout changes take 4 to 6 months. Complete gut-and-rebuild projects can take 6 to 12 months.

Should I move out during a home renovation?

For whole-home renovations, moving out is strongly recommended for safety, speed, and contractor access. Staying in a partially renovated home creates stress, slows construction, and poses health risks from dust and fumes. Many San Jose homeowners rent locally for 3 to 6 months during major renovations. Quartz Construction provides a timeline so you can plan your accommodations.

How do I choose between a renovation and new construction?

Renovation is generally more cost-effective if your home has good bones, you want to keep your location, and the existing structure is sound. New construction makes sense if the existing home has major structural issues or you want a completely custom layout. Quartz Construction can assess your existing home and help you decide the best path.

What renovations add the most value to a San Jose home?

The highest-value renovations in San Jose are kitchen remodels with 60 to 80 percent ROI, bathroom additions and remodels with 60 to 70 percent ROI, ADU additions often returning 100 percent or more via rental income, deck and outdoor living additions with 65 to 75 percent ROI, and energy-efficient upgrades including solar and windows.

Can I create an open floor plan during a renovation?
