Inspections

The City of Mt. Vernon Inspections Department helps make sure construction, remodeling, and additions are done safely and follow city rules. Inspectors work with homeowners, contractors, and developers to check that all work is safe and up to code.

When do you need an inspection?

You may need an inspection at different times during your project, such as:

• When walls, floors, or ceilings are opened during a remodel

• After digging, but before pouring footers or foundation walls

• Before underground utilities are covered

• Before insulation or drywall goes in

• After fire-rated walls are completed

• Before anyone moves into the building

• When the project is finished

When work is completed, you must schedule a final inspection. After the inspectors approve your project, you will get a Certificate of Occupancy.

How to Schedule an Inspection

Call 618-242-6830 at least 48 hours before you want the inspection.

You will need to provide:

• Your permit number
• The project address
• The type of inspection you need

Reminder: It is the permit holder or property owner’s job to make sure all required inspections are scheduled.
