Full Breakdown

01. The measurement runs from the footing base to the wall top, not from grade, so a wall with a deep footing can trigger the four-foot threshold sooner than it appears above ground. A retaining wall that carries a surcharge, extra load from a slope, structure, or vehicle above it, loses the exemption regardless of height and needs a permit. 02(b)(1)C uses the same four-foot, footing-to-top measurement but adds a second trigger: the exemption is also lost if the wall impounds Class I, II, or III-A liquids. 01, with engineering documentation as required for the applicable structural work.

Violations & Fines

Building a retaining wall over four feet in height (footing to top), or any surcharge-bearing wall, without first obtaining a building permit from the Division of Building Inspection is a code violation subject to correction, stop-work action, and after-the-fact permitting.

Frequently Asked Questions

How tall can a retaining wall be in Toledo without a permit?
Up to four feet under Toledo Municipal Code § 1305.02(a)(1)C, measured from the bottom of the footing to the top of the wall, not from visible grade, and only if the wall does not support a surcharge.
Does a retaining wall holding back a slope above it need a permit in Toledo?
Likely yes. Section 1305.02(a)(1)C removes the permit exemption for any wall supporting a surcharge, which includes extra load from an upslope grade, structure, or vehicle bearing on the wall, regardless of the wall's height.
Is the height measured from the ground or the footing in Toledo?
From the footing. Section 1305.02(a)(1)C measures retaining wall height 'from the bottom of the footing to the top of the wall,' so a buried footing counts toward the four-foot exemption threshold even though it isn't visible above grade.
