Tuscaloosa, AL Landscaping Rules: Composting (2026)

Table V-5, Accessory Uses and Structures Table, marks "Composting, small-scale" with a "P" in every column, residential, institutional, business, industrial and planned-development alike, so a backyard compost pile or bin needs no special exception or permit to establish anywhere in the city. Sec. " That means a compost operation cannot be placed in a side yard or front yard, only behind the house or main building, and even there it is capped at 15 percent of the rear yard's area, a meaningfully tighter limit than the 30-percent rear-yard coverage allowed for accessory structures generally under Sec.

25-106(b)(7). Because composting is classified as an accessory use rather than an accessory structure, it also has to remain incidental and subordinate to the principal use of the lot under the general accessory-use standards in Sec. 25-106(b), meaning a composting operation cannot become the primary use of a residential lot, such as a commercial composting business, without separate zoning approval as a different use category. The rule was adopted as part of the December 2024 Unified Development Ordinance rewrite (Ord. No. 9572, Sec. 2, effective 12-17-24) and has not been amended since in the two later ordinances touching this division.
