The department continues to provide services and information regarding planning, zoning, land development, permits, building inspections, code enforcement, neighborhood development and the Action Center. The department demonstrates the legal, administrative and implementation process related to the built environment within the city – residential and commercial.

Most permit applications require plans and construction documents to support the permit application. Plans should be prepared by a registered architect or design professional and must be drawn to scale, utilizing architectural graphic standards. The designer’s name, address and phone number must be on each sheet of the plans. If the total building area is 5,000 square feet or greater, regardless of the size of the project, plans must be prepared by an architect registered with the state of Mississippi or a qualified design professional.

Required building plans may include, but may not be limited to the following:

  • Floor Plan: Should include proposed construction as well as existing in order to verify means of egress and other code requirements.
  • Exterior Elevations
  • Foundation Plan and Details
  • Wall Sections and other Construction Details
  • Electrical Plan
  • HVAC Plan
  • Plumbing Plan 

In addition to building plans review, most commercial projects require approval by the Site Plan Review Committee. Refer to Development Information or call the Planning Division at 601-545-4599.


Most commercial projects require licensed contractors and sub-contractors. Refer to Contractor Licensing for specific requirements.


Permitted work must be inspected at all stages prior to cover-up. Please allow at least 24 hours advance notice when requesting inspections. Typical inspections for a new building include the following:

  • Building: footing, foundation, framing and final.
  • Electrical: temp. pole, rough in, building service, final.
  • Mechanical: rough-in, above ceiling, final
  • Plumbing: under-slab, stack-out, sewer tap/water connection, final

Other inspections may be required for certain projects. Remodel projects may not require all the above. The general rule of thumb is that any work performed must be inspected before it is covered.

Please call 601-554-1003 to schedule inspections.


Permit fees are based on the total cost of the project. Refer to the Permit Fee Ordinance or call 601-554-1003. Building permit fees do not include fees for plans review and public hearing application fees.
