Do You Need a Concrete Slab Permit in Mission?

Based on Mission's local building codes, you'll need a permit when:

Required·Rule 1

Concrete slabs over 200 square feet typically require a building permit. The permit ensures compliance with IRC R506 (slab design), proper drainage, and impervious surface limits where applicable.

Required·Rule 2

Any slab elevated more than 30 inches above adjacent grade requires a building permit. The IRC R105.2 exemption only applies to sidewalks and driveways at or near grade level. Elevated slabs are treated as structural elements and may require footings, guard rails (36 inches minimum per IRC R312.1 for walking surfaces 30+ inches above grade), and engineering review.

Required·Rule 3

Any concrete work in the public right-of-way (sidewalks, curb cuts, driveway approaches) ALWAYS requires a permit from Public Works or the Transportation department, not the building department. This applies even if you're replacing an existing damaged sidewalk in front of your own house. The permit ensures ADA compliance, proper slope, and coordination with existing public infrastructure.
