Quick Answer: A kitchen island in San Jose costs $800-$3,000 for a freestanding (movable) island with a butcher block or quartz top; $5,000-$12,000 for a built-in island with custom cabinetry, stone countertop, and seating overhang (no plumbing); or $12,000-$25,000 for a built-in island with a sink, dishwasher, or cooktop (requiring plumbing and/or electrical rough-in). The most popular island size for San Jose homes is 4 feet wide by 6-8 feet long with 3-4 counter stools on one side. Minimum clearance around an island: 42 inches on all working sides (36 inches is code minimum but 42 inches is comfortable with two cooks). A sink-in-island requires a plumbing permit in San Jose; a cooktop-in-island requires gas and/or electrical permits plus ventilation (pop-up downdraft or overhead duct).
