Direct Answer
In Hartford, retaining wall construction work generally requires a permit when the project exceeds $200 or involves system replacements. Your licensed contractor should pull the permit — if they ask you to pull it yourself, that's a red flag. Unpermitted work can cause problems when selling your home.
