Project questions
Frequently asked questions for Simpson County
Who handles permitting for this jurisdiction?
Simpson County Community Development Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 601-675-2366.
How long might review take?
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.
How are inspections scheduled?
The application includes a site-inspection date field. For manufactured homes, the fire-marshall inspection and decal must be completed before final setup, and the county building inspector must complete required inspections before power is released. Contact Community Development at 601-675-2366 or communitydevelopment@co.simpson.ms.us during office hours; submit plan PDFs by email as directed by the requirements sheet.
Which codes and exemptions should I review?
The county's Building Permit Requirements state that all construction must comply with county and state laws regulating construction and the 2021 International Building Codes. Metal-building plans must be stamped by a Mississippi-licensed engineer and use a 115-mph wind speed. No general minor/cosmetic exemption list is published; the county requires permits for new commercial and residential buildings, remodeling projects, and manufactured homes. Form 335 soil/site evaluation is not required when sewer is provided by a municipality or approved community system, but the final Form 910 is required before permanent-power release.
