Posts set above the local 30-inch frost line. Frost heave in Maryland's freeze-thaw cycles will lift footings, racking panels and compromising structural integrity. The 2021 IRC requires posts to be set a minimum of 6 inches below the frost depth. In Four Corners, this means a 36-inch minimum post depth is non-negotiable for a permanent installation.

Four Corners zoning enforces a 4-foot maximum in front yards and 6 feet in rear yards. For corner lots, a critical 'sight triangle' at property lines adjacent to streets like University Boulevard must remain clear of any visual obstruction below 42 inches. This is a safety mandate for driver visibility, especially given proximity to the I-495 corridor.

Design for the 115 MPH V-ult wind speed rating. This ultimate design wind speed, per ASCE 7-22 standards, dictates post spacing, concrete footing size, and bracket strength.

Maryland Code, Real Property § 11-108 and common law require you to notify adjoining property owners. For work in 2026, provide a formal notice describing the scope, materials, and timeline. If the fence is on the property line, you need their written consent per the 0-foot setback allowance. Proceeding without notice can lead to disputes and cost-sharing complications.
