Summary
A closed fence up to 6 feet along a shared side or rear lot line is exempt from setbacks, so it can sit on the property line. Maryland has no statute forcing neighbors to split fence costs; that stays a private matter.
For properties where the side or rear yard adjoins another lot line and not a public road: Closed fences, walls and retaining walls over three feet and up to six feet in height are exempt from structure or use setback requirements if located in a side or rear yard.
Full Breakdown
Under Zoning Regulations Section 128.0.A.9, closed fences, walls and retaining walls over three feet and up to six feet are exempt from setback requirements when located in a side or rear yard adjoining another lot line, so a boundary fence between neighbors is allowed. The county regulates height and placement, not who pays. Maryland has no general 'partition fence' cost-sharing law for residential lots, so an agreement between neighbors is advisable before building. A series of retaining walls near a residential property line has its own 10-foot standoff (see retaining walls).
Violations & Fines
Disputes over placement or encroachment are civil matters between owners; zoning enforcement addresses only height and setback violations, not cost-sharing or boundary disagreements.
