Summary
A retaining wall in Erie does not need a building permit if it stands four feet or less, measured from the lowest grade to the top of the wall, and does not support a surcharge, per City Code Section 1503.41(c)(1)B. Commercial retaining walls get the same four-foot exemption unless the wall also holds back Class I, II or III-A liquids.
Retaining walls that are not over four feet in height measured from the lowest level of grade to the top of the wall unless the wall supports a surcharge.
Full Breakdown
41(c)(1)B exempts residential retaining walls from Erie's building permit requirement when the wall is not over four feet in height, measured from the lowest level of grade to the top of the wall, as long as the wall does not support a surcharge. 31(c)(1)C, uses the same four-foot threshold but adds a second trigger: a commercial retaining wall still needs a permit if it impounds Class I, II or III-A liquids, categories covering many flammable and combustible fuels under the fire code's classification system. 31(a) before construction.
32(c) requires an engineer- or architect-prepared design once the work involves changes to a structure, which a tall retaining wall holding back soil or fill typically does. The exemption is narrow and height-only: it does not excuse a wall from meeting other applicable codes, and a wall built without a required permit is still subject to Erie's working-without-permit penalty.
Violations & Fines
A retaining wall built over four feet, or a shorter wall that supports a surcharge, without first obtaining the required City permit triggers the same enforcement as any other unpermitted construction: Section 1503.51 doubles the fee that would have applied, with a minimum penalty of $100, and does not excuse the wall from having to meet Uniform Construction Code standards. The Building Code Official can also order the work stopped under Section 1503.52 until compliance is shown.
