Columbia Residential Building and Trade Permit Guide

Columbia residential projects use building permits or building trade permits depending on whether the work needs zoning, plans, engineering, or other agency review.

Permit takeaway

Columbia says all regulated work in the city must have a permit, issued either as a Building Permit or a Building Trade Permit depending on the work.

Zoning and placement

Building permits typically require review by Permitting and Zoning and often another city division such as Engineering or Plans Examiner.

Building and trade review

Building trade permits cover electrical, mechanical, plumbing, and gas work that usually does not require zoning, plan examiner, engineering, or other outside review.

Call before applying when

Call before applying if the project changes structure, adds square footage, relocates trades, needs zoning review, or may involve engineering, design review, or a board approval.
