Columbia Missouri Residential Building Permit Guide

Columbia homeowners should use Building and Site Development resources to confirm when residential building, trade, zoning, and site permits are needed.

Permit takeaway

Columbia organizes building and site development review around permits, inspections, code compliance, and development requirements for work inside the city.

Zoning and placement

Planning and zoning issues can affect additions, accessory structures, lot coverage, setbacks, parking, floodplain areas, and site changes before a building permit can move forward.

Building and trade review

Building review should be coordinated with trade permits and inspections when a project includes electrical, plumbing, mechanical, structural, or exterior site work.

Call before applying when

Call before applying if the project changes the structure, expands the footprint, alters drainage, includes trade work, or raises a zoning question.
