Summary
A detached tool shed, storage building or similar accessory structure in unincorporated Ascension Parish can go up without a building permit only if it is one story and its floor area does not exceed 400 square feet. Ascension Parish Code § 6-5(501)(1)(a) sets that threshold; anything larger, or with a second story, needs Building Official approval before construction.
Permits shall not be required for the following: ... (1)Building.a.One-story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area is not greater than four hundred (400) square feet (thirty-seven (37) meters squared).
Full Breakdown
Section 6-5(501)(1) lists categories of work exempt from the parish's building permit requirement, and item (a) covers accessory buildings: one-story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area is not greater than four hundred square feet. The exemption is narrow: it covers only detached, one-story structures used for storage or similar accessory purposes, at or under 400 square feet. A shed built with a loft or second story, or one that exceeds 400 square feet, does not qualify and needs a permit under the general rule in section 6-5(500).
00 residential rate, the same fee charged for additions, renovations, modular units and reroofs. Exemption from the permit itself does not excuse the shed from every other rule: section 6-5(501)'s opening sentence warns that exemptions from permit requirements shall not be deemed to grant authorization for any work done in violation of the provisions of the title or any other laws or ordinances of the jurisdiction, so an exempt shed can still be cited if it violates a separate ordinance.
Violations & Fines
A shed or accessory building over 400 square feet, or one built with more than one story, built without first obtaining a permit is treated the same as any other unpermitted construction: section 6-8(802) sets a fine of $200.00 to $500.00, on top of the $125.00 permit fee still due, and the Building Official can order the work stopped.
