a development permit is required...
If you are planning a partition or subdivision, a construction project (large or small, such as a new house, an addition, a shed larger than 200 sq. feet, or a deck), an excavation, installation of sanitary sewer or a demolition, you will need to obtain a development permit from the City of Rivergrove before the County will issue a building, plumbing or electrical permit.
In general, work done entirely inside your home will not need a Development Permit, but first check with the City of Rivergrove to make a determination.
Any development in the floodplain or a Water Quality Resource Area requires a development permit.
If you are not sure if you need to submit a Development Permit Application, please contact the City to make a determination.
