: To provide efficient, effective and openly responsive customer service to all citizens with a courteous and friendly attitude.

Bay St. Louis is a building friendly city, but does follow the rules as outlined in the codes adopted by its City Council.  There is a staff member available to assist in your planning, by appointment or occasionally by chance. It is a one-stop shop for information, permits and guidance for residential or commercial building within the expanded city limits, including, the new territory annexation approved by the courts in 2006.  The old adage, “measure twice, cut once” applies to the Building Department.  Ask questions first; don’t pay a higher price later.

The Building Official and his staff are responsible for all development within the city limits of Bay St Louis.  Construction, plans review, floodplain, Community Rating System and Code Enforcement are some of their assigned tasks.  From the first permit to the last inspection, the Building Department has instituted a system of customer service and convenience.
