Can an HOA restrict a shared or boundary fence between neighbors?

How HOA architectural authority interacts with good-neighbor fence laws on a shared boundary, who pays to build and maintain a line fence, and how to sort out a dispute over a fence between two lots.
The short answer
Usually yes - but a shared boundary fence has two layers of rules, not one. The HOA's architectural authority still governs what the fence looks like (height, material, color, placement, approval), the same way it does for any fence; our guide on whether an HOA can tell you what kind of fence you can build covers that side in depth. Layered on top is a separate body of state 'good-neighbor' or division-fence law that governs the relationship between the two adjoining owners - who can build on the line, who shares the cost, and who keeps it maintained. So a fence sitting on the property line between two homes has to satisfy the association's aesthetic standards and the neighbor-to-neighbor cost-and-maintenance rules at the same time.
The HOA's architectural authority still applies
Putting a fence on a shared line doesn't exempt it from the community's rules. If your CC&Rs give the board or an architectural committee power over exterior improvements, a boundary fence typically needs approval just like any other, and it has to meet the community's height, material, style, and placement standards. Many communities also have specific rules for fences on interior lot lines - requiring a single approved style so adjoining backyards read consistently, or designating certain perimeter or common-area fences as the association's responsibility rather than the owners'. The first step with any shared fence is still to submit the plan and get written approval; building first and asking later is the classic mistake regardless of whose line the fence sits on.
Good-neighbor fence laws: who pays to build and maintain
Separate from the HOA, most states have a division-fence or 'good-neighbor fence' statute governing fences on a shared boundary. California's Good Neighbor Fence Act of 2013 (Civil Code section 841) is a well-known example: it presumes that adjoining landowners share equally in the reasonable cost of constructing and maintaining a fence on their common boundary, and it requires an owner who wants to build or replace a shared fence to give the neighbor at least 30 days' written notice describing the problem, the proposed work, and the estimated cost. Other states have their own partition-fence or division-fence laws with different notice and cost-sharing rules. These statutes are what decide the money question between two owners - the HOA generally doesn't referee that split unless the fence is association property or its documents say otherwise.
Who actually owns and maintains a line fence
On a true boundary fence, ownership is usually shared, and that shapes maintenance responsibility. A fence straddling the property line is typically a joint asset of both adjoining owners, each responsible for a share of upkeep under the applicable fence law; a fence built entirely on one owner's side of the line is generally that owner's alone. Where exactly the line runs matters enormously, so a survey - not a guess - settles whose land the fence sits on and whether a neighbor or the HOA is encroaching. For perimeter or common-area fencing the association installed, the HOA usually owns and maintains it. Sorting out whether a given fence is yours, your neighbor's, jointly shared, or the association's is the same maintenance-line question our guide on whether the HOA or the homeowner is responsible for repairs walks through.
How to handle a shared-fence dispute
Start by separating the two questions: appearance and approval are the HOA's lane; cost and maintenance between you and your neighbor are governed by your state's fence law and the property line. Confirm the boundary with a survey if it's unclear, read your CC&Rs and architectural guidelines for any shared-fence rules, and check your state's good-neighbor or division-fence statute for the notice and cost-sharing steps. If you're building or replacing a shared fence, give your neighbor the written notice the law requires and get HOA approval in writing before any work starts - doing both up front prevents almost every later argument about who agreed to what. For boards, the way to keep boundary-fence disputes from festering is clear, published standards, a documented approval process, and an unambiguous record of which fences are the association's and which belong to owners - exactly the kind of architectural and maintenance record OurHOA helps small self-managed communities keep, so 'whose fence is it, and who pays' stops being a recurring fight.
