Harford County Fence Permit Cost (2026)
Residential fence building permit fees in Harford County, Maryland, pulled directly from the official Harford County Department of Inspections, Licenses and Permits (DILP) Fee Schedule. A fence permit is $20 for a fence up to 250 linear feet, plus $0.10 per foot for every foot over 250. Maryland has no statewide percentage levy, so there is no Virginia-style 2% add-on. Whether your specific fence needs a permit - and any height or setback limits - is set by county code separately from the fee.
This guide covers: Harford County, Maryland residential fence building permit fees as published in the DILP Fee Schedule (Bill 24-013): the $20 base fee for a fence and the $0.10-per-foot add-on for length over 250 feet.
This guide does NOT cover: Whether your specific fence requires a permit (set by county code), height and setback limits, corner-lot sight-triangle rules, HOA architectural approvals, and fence contractor or material costs. A retaining wall is a different permit line (see the related-permits note below).
Important note: The fee here is the building permit charge only. Confirm with DILP whether your fence needs a permit and what height and placement rules apply before you build.

- For longer runs, add $0.10 per foot over 250 ft: a 400-foot fence is $20 + (150 × $0.10) = $35; a 600-foot fence is $55.

- A retaining wall is billed differently: $30 if no building permit is required, or $2.00 per linear foot plus a $100 application fee if a building permit is required.
