We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all our projects, no matter how big or small. We are experts in our trade, and will always keep you educated on your task or project.

"The project was a 1938 home that was never remodeled, it needed new plumbing and electrical, updating the kitchen and master bath into this century! Interviewed 5 contractors and chose Build Ur Dream, and from the start it was a smooth process. First off, the Owner Eli, came out to the site, listened to the ideas of what was needed and the overall design of the finished project. I visited the showroom, met with Vincent the design consultant, who helped out with the flooring, fixtures, countertop and cabinets, Eli assigned Victore as the lead project manager, great communication with both via text and phone. Victore was a pleasure to work with, if a issue came up, as they do in a older home remodel, we as a team discussed the options and came up with a plan. Victore and the team worked everyday, I mean there was someone or something being done to move the project forward everyday, even Saturday and Sundays. My home was completed on time and in budget, 2 1/2 months from start to finish. Super happy with the work, craftsmanship and enjoying my home."

FAQs for basement remodeling projects in San Jose, CA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
