When the snow melts and the weather starts to warm, project season begins. The Building & Planning Department of the city of Grinnell would like to remind property owners what projects require a permit.
Building permits are required for all new buildings or alterations to existing buildings. There are several alterations that do not require a permit: nonstructural alterations not exceeding $500.00, paneling, cabinet replacements, door and window replacement if replaced with an equal size, storm window or screen replacement, gutter addition or replacement, repairs of porches, painting, floor coverings, and ordinary maintenance work.
Permits are required to install a fence, add a porch or deck, add a garage or shed, replace a roof, and pave a previously unpaved driveway or add to an existing paved driveway. Replacement or addition of mechanical systems such as central air conditioners, furnaces, and air handlers all require a mechanical permit. New installation or replacement of existing plumbing equipment including water heaters and supply, drain, and vent lines require a plumbing permit. Fixtures such as toilets, faucets, and shower heads do not require a permit as long as there is no interference with the existing valve.
Before doing any project, if you are unsure as to whether a permit is required, contact city hall at 641-236-2600 and ask to speak to a member of the Building & Planning Department staff. By obtaining a permit you are ensuring the work being done at your home or business is done safely and follows standard building practices.
