Quick Answer: Removing a wall to create an open floor plan in San Jose costs $5,000-$25,000 for a load-bearing wall (including engineering, beam installation, permits, and finishing). A non-load-bearing partition wall removal costs $1,500-$5,000. The most important first step: hire a structural engineer to identify whether the wall is load-bearing before any work begins.
Open Floor Plan Renovation in San Jose
Helpful Resources:
Opening up the kitchen-to-dining-to-living room is one of the most popular renovations for older Bay Area homes. Many San Jose homes built in the 1950s-1980s have compartmentalized floor plans with galley kitchens walled off from the rest of the home. Removing those walls transforms daily life.
How to Tell If a Wall Is Load-Bearing
- Runs perpendicular to floor joists: If the wall runs perpendicular (at 90 degrees) to the joists above, it’s likely load-bearing
- Located at or near the center of the house: Center walls often carry ridge beam loads or transfer upper floor loads
- Sits above a foundation wall or beam: If there’s a beam, post, or foundation wall directly below it in the crawl space, it’s load-bearing
- Has a wall or column directly above it on the next floor: Any wall that is “stacked” above/below another wall is likely in the load path

| Load-bearing wall (10 ft) | $8,000-$18,000 | Engineering, temporary shoring, steel beam/LVL, posts, permit, finish |

The Process: Opening a Floor Plan
- Step 1: Structural engineer inspects and confirms wall type; provides beam specifications
- Step 2: Building permit obtained (wall removal always requires a permit in San Jose)
- Step 3: Temporary shoring walls installed to support structure during work
- Step 4: Wall demolished; utilities (electrical, plumbing, HVAC) rerouted
- Step 5: Steel or LVL beam installed; posts set at each end
- Step 6: Rough inspection, then drywall, paint, and flooring patched to match
- Step 7: Final inspection
