Why It Matters
Whether you’re a homeowner doing a bathroom remodel or a contractor pulling permits on behalf of a client, having a quick, transparent way to calculate permit fees builds trust and avoids surprises.
The Town of Lexington charges by the estimated cost of the work — $13 per $1,000 — plus fixed amounts for plumbing and other specialty work. If you're planning a major upgrade, even small oversights in permit costs can delay inspections or result in costly penalties.
This tool is ideal for:
Lexington homeowners
General contractors
Designers and architects
Real estate investors and developers
