Full Breakdown
Town of Colonie Code § 62-14 sets the default rule that any work regulated by the Uniform Code or Energy Code needs a building permit before work starts, but Subsection B carves out a list of exempt work. " A typical landscaping retaining wall holding back a sloped yard falls outside the permit requirement entirely, so a homeowner can build one without filing with the Building Department Manager. The exemption flips, however, the moment the wall is doing more structural work than holding soil: a wall engineered to carry a surcharge load, such as weight from a driveway, structure, or fill placed above it, or one that impounds a flammable or combustible liquid in the Uniform Code's Class I, II or IIIA categories needs a full building permit application under § 62-14D, reviewed for Uniform Code and Energy Code compliance under § 62-16 before the Building Department Manager can issue it.
" So even an exempt retaining wall still has to be built to Uniform Code structural standards; the code just does not require formal Town sign-off before construction begins unless the surcharge or liquid-impoundment trigger applies.
Violations & Fines
A retaining wall built to carry a surcharge or impound regulated liquids without the required permit is treated as unpermitted construction under Chapter 62. The Building Department Manager may issue a stop-work order under § 62-21, and § 62-26 sets penalties of up to $500 or 15 days in jail per violation, or a civil penalty of up to $500 for each day the violation continues, recoverable in the name of the Town of Colonie.
