Summary

SDCL Chapter 40-28 (Partition Fences) governs shared boundary fences between adjoining agricultural landowners in South Dakota's open-range/fence-out tradition: each adjoining owner shares equitable maintenance, with disputes resolved by township fence-viewer proceedings. This statute does NOT apply to urban/suburban residential boundary fences, which are governed by private agreement and local ordinance.

Unless adjoining landowners otherwise agree, every owner of land shall be liable for one-half of the expense of erecting and maintaining a partition fence between his own and adjoining lands. However, no owner of land is liable for such expense if neither keeps livestock on the affected tract of land and neither derives any other substantial benefit from the fence for a period of five years from the date of erection or repair of the fence.

Full Breakdown

Per SDCL Chapter 40-28, when two or more agricultural landowners share a common boundary fence enclosing land used for livestock, each owner is responsible for an equitable share of construction and maintenance. Disputes over allocation are resolved through fence-viewer proceedings administered by the local township board of supervisors or county commission. The statute reflects South Dakota's strong livestock and ranching heritage and the fence-out (open-range) legal tradition. In urban and suburban residential settings, Chapter 40-28 generally does NOT apply: residential neighbor-fence cost allocation is a private-contract matter, and disputes over a residential boundary fence are resolved through district court (boundary-line action, prescriptive easement, adverse possession) or by negotiated written agreement. Local city ordinances may require a survey, building permit, or written notice to the adjoining property owner before constructing a boundary fence; these requirements are authorized under SDCL Chapter 11-4 (municipal zoning).

Violations & Penalties

Agricultural partition-fence cost-sharing disputes proceed through the township fence-viewer process under SDCL Chapter 40-28; the prevailing party may recover the equitable share owed plus costs. Residential neighbor-fence disputes are civil matters resolved in small-claims or circuit court: no criminal penalty applies.

Frequently Asked Questions

Does a neighbor have to pay for half my residential fence in South Dakota?

No, not by state statute. SDCL Chapter 40-28 cost-sharing applies only to agricultural partition fences. Residential cost-sharing requires a written agreement between neighbors.

What is a 'fence viewer'?

Under SDCL Chapter 40-28, fence viewers are township-board or county-commission officers who resolve disputes between adjoining agricultural landowners over partition-fence construction and maintenance.

Do I need to notify my neighbor before building a fence?

South Dakota state law does not require neighbor notice. Many cities require a building permit and a survey; some require written notice to the adjoining owner. Check your local code.
