Where this term shows up in permit work and how it affects the project
It can add fees, corrections, and disclosure risk. During a sale, unresolved unpermitted work can become a negotiation or lender issue.
If this term appears in a form, plan comment, or local ordinance, start with the building permit guide, compare it against the zoning permit guide, then use the permit guide directory to find the right local path.
