6 rules for unincorporated St. Joseph County, Indiana.
Verified from official government sources
In unincorporated St. Joseph County, open fences like chain-link may reach 8 feet and solid privacy fences 6 feet, dropping to 4 and 3 feet within the front setback. The Area Plan Commission's zoning ordinance sets these limits; South Bend and Mishawaka run their own.
A building permit is required to install a fence in unincorporated St. Joseph County, reviewed by Planning and Zoning against the ordinance's height and location standards. Call Indiana 811 at least two full working days before digging post holes.
Indiana's partition-fence law makes adjoining landowners share a boundary fence's cost proportionally, and it matters most on St. Joseph County's rural south and west farmland. If a neighbor refuses, you may build, give twenty days notice, and recover their share.
Indiana Code § 32-26-9-3(a)
A partition fence shall be built, rebuilt, and kept in repair at the cost of the property owners whose properties are enclosed or separated by the fences proportionately according to the number of rods or proportion of the fence the property owner owns along the line of the fence.
A retaining wall over four feet tall, measured from the bottom of the footing, needs a building permit and engineered design under the Indiana Residential Code. Shorter unloaded walls are exempt. St. Joseph County building officials enforce this.
Every residential pool in St. Joseph County must be enclosed by a barrier at least four feet high, about 48 inches, with self-closing, self-latching gates that lock. The requirement comes from the Indiana Residential Code and is enforced by local building officials.
675 IAC 14-4.4-38 (Indiana Residential Code § R326.27.3)
Walls or fencing not less than four (4) feet high and completely surrounding the pool and deck area with the exception of self-closing and latching gates and doors, both capable of being locked.
No Indiana statute restricts residential fence materials, so wood, vinyl, aluminum, and chain-link are all allowed across St. Joseph County. County zoning instead regulates height by openness, and barbed wire and electric fencing are treated as agricultural.
