Full Breakdown

Section 4.1 of the Troup County Unified Development Ordinance, adopted by Ordinance No. 2025-03 on June 3, 2025, authorizes the flood damage prevention article under Article IX, Section II of the Georgia Constitution and O.C.G.A. § 36-1-20(a). Section 4.2 sets its reach: the article applies to all areas of special flood hazard within unincorporated Troup County, based on the Federal Emergency Management Agency's flood insurance study dated April 19, 2017, with its accompanying maps, plus any area known to have flooded historically even if not yet mapped.

The FIS and maps are kept for public inspection at 100 Ridley Avenue, Suite 1300, LaGrange. Before any structure is located, extended, converted or altered in a flood hazard area, or before filling, grading or other development begins, the owner must obtain a development permit; no work may proceed without full compliance with the article and other applicable regulations. Where this article conflicts with another ordinance, easement, covenant or deed restriction, whichever imposes the stricter limit controls, and every requirement is treated as a floor, not a ceiling.

Violations, including failing to secure a permit or meet conditions attached to one, are punishable under Chapter 1, Section 1-19 of the County Code, and each day a violation continues is a separate offense; the County can still pursue any other lawful remedy on top of any fine.

Violations & Fines

Building, filling, grading or altering land in a mapped flood hazard area without first obtaining a Section 4.2 development permit is a violation punished under Chapter 1, Section 1-19 of the County Code, with each day of continued noncompliance charged as a separate offense; the County can pursue any other lawful action needed to stop or remedy the violation alongside the fine.

Frequently Asked Questions

Do I need a permit to build in a flood hazard area of unincorporated Troup County?

Yes. Section 4.2 of the County's Unified Development Ordinance requires a development permit before any structure is located, extended, converted or altered, and before any filling, grading or other development activity begins within an area of special flood hazard mapped on FEMA's April 19, 2017 flood insurance study for Troup County.

Where can I check whether my unincorporated Troup County property sits in a mapped flood hazard area?

The flood insurance study and accompanying maps adopted by Section 4.2 are kept for public inspection at the Community Development office, 100 Ridley Avenue, Suite 1300, LaGrange, and the Community Development Director administers and interprets the boundaries shown on those maps for permit applicants.

What is the penalty for developing in a Troup County flood hazard area without a permit?

Section 4.2 makes a violation punishable under Chapter 1, Section 1-19 of the County Code, and treats each day the violation continues as a separate offense, on top of any other lawful action the County takes, so an unpermitted fill or structure can generate a fine for every day it remains in place.
