FENCE RULES – ST. MARYS (CITY), OHIO

OVERVIEW

Residential fences are permitted on private property within City of St. Marys, subject to local regulations.

Local fence rules for the City of St. Marys appear primarily in Section 370 of the St. Marys Zoning Regulations, the City’s zoning-permit guidance and application materials, Section 521.07 of the Codified Ordinances, and the City’s public-right-of-way permit materials. The City of St. Marys Engineering Department administers zoning-permit intake and zoning review.

This page focuses on typical single-family residential fencing. If the jurisdiction’s code, ordinance, or zoning-resolution materials do not state a specific limit or requirement, this page notes that the controlling regulatory text does not specify one. If no local code, ordinance, or zoning resolution is available in the approved source packet, this page notes that the jurisdiction does not publish the relevant standard in the referenced published materials.

GOVERNANCE

The City of St. Marys regulates residential fences through the St. Marys Zoning Regulations, especially Section 370, Miscellaneous Requirements. The zoning ordinance applies throughout the land within the City’s corporate limits.

The City of St. Marys Engineering Department accepts zoning-permit applications and reviews proposed fence locations against the zoning requirements. The Zoning Enforcement Officer issues and revokes zoning permits under Section 500, and the City’s published permit guidance identifies the Director of Public Service and Safety as the official making the final zoning determination.

The official Ohio Board of Building Standards lookup for St. Marys states that the municipality does not fall within a jurisdiction certified to enforce the Residential Code of Ohio for one-, two-, and three-family dwellings. The City’s permit page separately directs commercial and industrial projects, including residential buildings with four or more units, to Miami County Ohio Building Regulations; that referral does not establish residential-code administration for ordinary one-, two-, or three-family properties.

The Director of Public Service and Safety administers the City’s special privilege process for objects placed over or upon City right-of-way and the dangerous-building provisions that expressly include unsafe or deteriorated fences.

PERMIT AND APPROVAL REQUIREMENTS

• Zoning Permit: A City of St. Marys zoning permit is required for any fence. Removing an old fence and installing a new fence in the same location still requires a zoning permit.

• Application Materials: The applicant must provide a sketch showing the proposed fence location, dimensions, and distances from property lines. The City’s permit schedule lists a $10 zoning-permit fee.

• Residential Building-Department Context: Official sources show that no certified residential building department has jurisdiction for City of St. Marys. Under the Residential Code of Ohio administration provision for such areas, the owner is not required under that chapter to submit construction documents, seek approvals, request inspections, or obtain certificates. Separate zoning-permit, placement, right-of-way, and private requirements remain independent.

• Public Right-of-Way: The City separately requires a special privilege permit for a sign, canopy, or other object placed over or upon City right-of-way. This process is relevant when fence work would occupy the right-of-way. The special privilege permit does not otherwise exempt the work from the zoning ordinance, except as the permit addresses yard requirements.

• Pool-Related Fencing: The City requires zoning permits for both fences and pools. A qualifying privacy fence exceeding 3 1/2 feet may be used in a rear yard around a private swimming pool only under the placement and setback conditions stated in Section 370.

FENCE PLACEMENT RULES

• Front Yard: A fence may not be constructed in the front yard.

• Division-Line Placement: The zoning ordinance regulates fences along the division line between lots and does not state a separate setback for a standard division-line fence; however, the fence must be located entirely on the owner’s property and must not encroach into rights-of-way or easements.

• Side-Yard Connection: A fence up to 3 1/2 feet high may be constructed in a side yard to connect a 3 1/2-foot fence along the side property line to a structure.

• Rear-Yard Privacy Fence: A privacy fence exceeding 3 1/2 feet may be erected in a rear yard around a patio or private swimming pool and may be attached to the residence, provided the fence meets the applicable side- and rear-yard setbacks for the zoning district.

• Corner Lots: Within the corner visibility area formed by the intersecting street lines and a line connecting points 20 feet from their intersection, a fence or other structure in the established front or side yard may not exceed 4 feet. Plantings in that area may not materially obstruct a driver’s view when approaching the street or alley intersection.

• Property-Line Information: The zoning-permit sketch must show the proposed location and distances from lot lines. The City of St. Marys Engineering Department does not perform surveys or locate private property lines.

• Utility Safety: Ohio law requires notice through OHIO811 before excavation where Ohio’s underground utility protection law applies. For covered fence work involving digging, drilling, augering, boring, grading, or other excavation, notice must be given at least two working days, not including the day of notification, but not more than 16 calendar days before excavation begins. For an owner personally excavating at property containing one through four dwelling units or another property category covered by the statutory owner-excavator provision, the notice requirement does not apply unless excavation is planned in a utility easement, a public right-of-way, or an area where utility facilities are known to serve the property; an excavator employed by the owner must comply. OHIO811 is a notification center and does not mark lines itself; participating utilities or their locators mark covered facilities and provide positive-response information. This statewide utility-notice framework is separate from local fence permitting, zoning certificates, development approval, easement limits, right-of-way approvals, floodplain review, stormwater review, drainage review, road or county-engineer review, historic or design review, HOA restrictions, and other applicable requirements.

FENCE HEIGHT AND VISIBILITY RULES

• Division-Line Height: A fence along the division line between lots may not exceed 3 1/2 feet when any part of the fence is within 20 feet of a residence building on the subject lot or an abutting lot. Under this paragraph, a taller division-line fence is not prohibited only when no part of the fence is within 20 feet of either residence, subject to the other zoning requirements.

• Side-Yard Connection Height: The permitted side-yard connection between a side property-line fence and a structure is limited to 3 1/2 feet in height.

• Rear-Yard Privacy Fence: A privacy fence may exceed 3 1/2 feet when it is located in the rear yard around a patio or private swimming pool and satisfies the zoning district’s side- and rear-yard setbacks. The zoning ordinance does not specify a maximum height for this qualifying privacy-fence configuration.

• Corner Visibility: Within the defined 20-foot corner visibility area, fences and other structures may not exceed 4 feet, and foliage may not materially obstruct approaching drivers.

• General Height Structure: The zoning ordinance does not publish one general maximum height for every standard residential fence. The controlling limits depend on division-line proximity to residences, front-yard prohibition, corner visibility, and the narrow rear-yard privacy-fence provision.

• Building-Code Distinction: The Residential Code of Ohio administration framework is separate from these City zoning height and placement rules. The official Board of Building Standards lookup shows no certified residential-code enforcement jurisdiction for St. Marys.

MATERIAL AND CONSTRUCTION LIMITS

• Electric Fences: A fence charged with electrical current is prohibited.

• Barbed Wire Near Streets and Sidewalks: A barbed-wire fence may not abut or be adjacent to a public street or sidewalk. Up to three strands of barbed wire may be placed on top of a fence that is not itself a barbed-wire fence when the strands are at least 72 inches above the ground. The code separately preserves barbed-wire partition fences where Ohio Revised Code Section 971.03 applies.

• Other Residential Materials: Beyond the electrical-current and barbed-wire provisions, the zoning ordinance and codified fence section do not specify a defined list of permitted residential fence materials, a finished-side orientation rule, or an opacity standard for ordinary residential fences.

• Condition and Maintenance: A fence may be treated as a dangerous structure when faulty construction, age, lack of repair, fire or wind damage, instability, collapse risk, or another condition creates a health or safety hazard. Dangerous fences are declared public nuisances under the City’s dangerous-building chapter.

PRIVATE RESTRICTIONS

Private restrictions operate independently from City of St. Marys fence rules.

HOA covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, recorded agreements, conservation easements, and other private property restrictions may impose stricter limits than the City’s zoning and right-of-way rules.

A City zoning permit or other municipal approval does not determine private boundary rights, private easement rights, HOA approval, or compliance with private covenants.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Zoning Permit Review: Constructing or replacing a fence without the required City zoning permit, or constructing a fence that does not match the submitted location, dimensions, and lot-line distances.

• Front-Yard Placement: A fence constructed in a prohibited front-yard location.

• Height and Residence Proximity: A division-line fence exceeding 3 1/2 feet when any portion lies within 20 feet of a residence building on either lot, or a side-yard connection exceeding 3 1/2 feet.

• Rear-Yard Privacy Fencing: A privacy fence exceeding 3 1/2 feet that is not within the limited rear-yard patio or private-pool context, or that does not meet the applicable side- and rear-yard setbacks.

• Corner Visibility: A fence or other structure exceeding 4 feet within the defined 20-foot corner visibility area, or foliage that materially obstructs a driver’s view.

• Prohibited Fencing: An electrically charged fence, or barbed-wire fencing adjacent to a public street or sidewalk that does not satisfy the stated elevated-strand provision.

• Public Right-of-Way: A fence-related object occupying City right-of-way without the applicable special privilege permit.

• Unsafe Fence Conditions: A fence that becomes unstable, deteriorated, damaged, collapse-prone, or otherwise dangerous under the City’s dangerous-building provisions.

• Residential Building-Code Administration: The official Board of Building Standards lookup shows that St. Marys does not fall within a jurisdiction certified to enforce the Residential Code of Ohio for one-, two-, and three-family dwellings. This status does not remove the City zoning-permit requirement or local fence standards.

• Utility Safety: Fence-post excavation or other covered digging that does not follow OHIO811 notice and positive-response procedures.
