What a roof replacement permit costs in Maryland
3 Maryland jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
Building permits are valuation-based: "$0-$3,000 | $86.00" rising to "Above $25,000 | $242.00 plus .010 times estimated cost above $25,000.00", plus "A non-refundable application fee of $43.00 will be added to all building permits." Minimum Building Permit Fee $86.00 (Permit Fees page, effective October 1, 2024).

- Is there a roof replacement permit exemption in Maryland?
