About each permit

Floodplain Development Permit (Unincorporated McLennan County)

The county's Floodplain Information page states: "All development in the unincorporated areas of McLennan County must comply with the county's flood damage prevention order." That order, dated September 23, 2008 and adopted under Water Code sections 16.313, 16.315 and 16.318, requires a Floodplain Development Permit (Article 3, Section C) and appoints the County Engineer as Floodplain Administrator (Article 4, Section A). Article 4, Section D says fees are paid "in accordance with the schedule established from time to time by the Commissioners Court", with the application, payable to McLennan County, and that "Fees will not be refundable"; no permit issues until the fee is received. A violation is a Class C misdemeanor, each day a separate offense (Article 6, Section A). The Engineer's Office determines from a survey or drawing whether a tract lies in the 100-year floodplain. This applies to development on a site in a special flood hazard area in the unincorporated county.

Notice of Residential Construction in the Unincorporated Area (IRC)

This record is for builders of homes. The county's Residential Building Requirements page states that McLennan County adopted the state's residential building code provisions on October 13, 2009 and revised its order on September 15, 2020, so that in the unincorporated areas all new residential structures, and improvements that increase square footage or value by more than 50 percent, must be built to the International Residential Code applicable in the county seat. The page says "McLennan County does not have inspection authority or responsibility and can not charge fees"; instead the builder notifies the county of the location, approximate completion date and IRC version (Attachment A), obtains 3 inspections at different phases of construction, and submits the inspection compliance notice (Attachment B) to the county and the owner. Failure to submit the reports is a Class C misdemeanor, and the page cites Local Government Code section 233.157. The page says the penalties do not apply to an individual building their own primary residence as their own contractor. Notices go to the County Engineer's Office, 215 N. 5th St., Suite 130, Waco.
