Development Process
We’re thrilled that you want to be in Slidell!
The tabs below provide an overview of the process for different types of development activity in Slidell. Click here for a printer-friendly version of this information.
We’re here for you! Join us at a Development Meeting.
Before opening a business, occupying a building or site, or starting any type of development, we encourage you to meet with us to discuss what will be required. A Development Meeting is your opportunity to meet with representatives from several City departments and receive guidance on the City’s process and requirements. It is required for new commercial construction and encouraged for all development.
Fill out a Request for a Development Meeting (pdf; 0.2MB) and submit it to the Planning Department. The more information you provide in the request, the better we can assist you. If you have questions, please ask a Planner for assistance (planningdept@cityofslidell.org or 985-646-4320). Development Meetings are generally scheduled for Wednesday at 9 am or 10 am, and must be scheduled at least a week in advance.
Is what I want to use the property for permitted?
To find out, ask a Planner (planningdept@cityofslidell.org or 985-646-4320). Each property in Slidell is located in a zoning district. Each zoning district permits certain uses, allows some uses under certain conditions and with legislative approval, and prohibits others.
What types of approvals might be required?
Depending on what you are doing, you may need one or more approvals from the City of Slidell (listed below). Please note that in addition to City approvals, you may also need approvals from other agencies, such as the State. City staff can help find out what other approvals you need, but it is your responsibility to ensure that you have all the required approvals.

What is the review process? How long will this take?
There are two types of review processes – legislative and administrative.
Legislative reviews require public hearings. The public must be provided notice of these hearings, which adds time to the process. The quickest is the Certificate of Appropriateness, which takes at least two weeks. Subdivisions and variances take at least one month. All other legislative reviews take at least three months. For more information about each legislative body, including application deadlines if applicable, click below:
- City Council
- Planning & Zoning Commissions (P&Z)
- Board of Zoning Adjustment (BZA)
- Olde Towne Preservation District Commission (OTPDC)
Administrative reviews are entirely at the staff level. Staff review the application and approve it if it meets all applicable regulations. Staff may also suggest modifications to help meet code requirements. Administrative review can be done in as little as a day or may take a few weeks, depending on the complexity of the project, staff workload, and the applicant’s responsiveness to requests for information.
