Advertise on This PageHow to Apply for a Permit in Unincorporated Waller County
Apply for a development permit, and for a driveway or culvert permit, online through the county's MyGov permit portal (MGO Connect), linked from the Waller County Road and Bridge Department page. Check the FEMA flood map or the county's flood map first: development in a mapped Special Flood Hazard Area needs a Floodplain Development Permit from the County Floodplain Administrator before work starts, and the county asks you to schedule a pre-application meeting with the Engineering Department before dividing or developing land. For commercial, public and four-plus unit apartment buildings, also submit a fire code application with the plan review fee and stamped plans to the Waller County Fire Marshal's Office (wcfmo@wallercounty.us); the Fire Code Building Permit issues once the fee is paid, by credit card or by check payable to Waller County (no cash).
