Do I need a permit for a concrete patio or retaining wall in Dublin?
Usually yes for a patio, because patios are on the city's list of work that needs a building permit. The city's exempt list covers a retaining wall no more than three feet tall, unless it supports added weight above it, such as a driveway, or a ground slope of five percent. Driveways aren't named on the list either way, so we'll ask Building and Safety about yours before we plan the pour.
