Summary
Boston only requires a fence-specific permit inside its historic districts. Property under the Beacon Hill or Back Bay Architectural Commissions, the Boston Landmarks Commission, or a Chapter 40C commission needs a Certificate of Appropriateness/Design Approval before installing or changing a fence, at a $50 design-review fee.
The fee for the application for a Certificate of Appropriateness/Design Approval and/or Exemption by the secretary of the Beacon Hill or Back Bay Architectural Commissions or the Boston Landmarks Commission (including any of its district commissions) or any Commission established under M.G.L. Chapter 40C shall be...in the case of design changes to the exterior architectural features of a building and/or site, including changes to or installation of doors, windows, fire balconies, exterior signs, marquees, awnings, roof decks, handrails, fences, porches, masonry garden walls/retaining walls, lowered window sills, changes to siding or roofing materials, skylights, solar panels...ramps and sidewalks, new chimneys and flues, residential vents, meters, mechanical/HVAC equipment, major masonry repair...and major landscaping...$50.

Full Breakdown
Boston's own code doesn't set a citywide fence permit; the requirement is tied to historic-district design review. L. Chapter 40C, installing or changing a fence is treated as a design change to the exterior architectural features of the building or site. That places it in the $50 fee tier alongside masonry garden walls and retaining walls, siding or roofing material changes, porches, handrails, skylights, solar panels, and new chimneys: all reviewed by the same commission through a single Certificate of Appropriateness/Design Approval application. Minor exterior modifications that don't rise to a design change fall into a cheaper $25 tier, while major alterations to exterior design or form cost $100, and major new construction costs $250; projects over $500,000 in cost pay one-half of one percent of the fair cost, capped at $5,000.
The commissions may waive or reduce fees for hardship cases or removal of unsafe or unsightly elements. Outside these designated districts, this ordinance imposes no fence-specific review, and the code contains no other fence-permit section.
Violations & Fines
The ordinance sets no separate fine for skipping the review; it only fixes the design-review fee itself. In practice, a fence project inside one of these historic districts that lacks a Certificate of Appropriateness can be held up at the building-permit stage, since Boston's general building/demolition permit under § 18-1.2(BB) is issued by the same Commissioner of Inspectional Services who administers the historic-district review process.
