How much does a basement conversion cost?
Last Updated June 24, 2026
The cost of a basement conversion depends on what you're starting with and what your goals are. Your current basement conditions will determine costs for essential things, like structural work, excavation for added headroom, waterproofing, utility upgrades, egress windows, insulation, and permits. Your goals may determine costs for optional things like cabinetry and other built-ins, upgraded finishes, entertainments systems, etc. Meet with a Neil Kelly designer for a project-specific estimate.
