FENCE RULES – DECATUR (CITY), ALABAMA
OVERVIEW
Residential fences are permitted on private property within City of Decatur, subject to local regulations. For properties located outside City of Decatur municipal limits, unincorporated areas are regulated by the applicable county, including Morgan County and Limestone County where applicable.
Local fence rules appear primarily in the Decatur Zoning Ordinance, including Section 25-5.5, Fence and Wall Standards, with related review through the City of Decatur Building Department, the City of Decatur Planning Department, floodplain materials, and historic-overlay materials administered through the City of Decatur Architectural Review Board.
This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted materials do not state a specific limit or requirement, this page notes that the code does not specify one.
Compiled From City of Decatur Building Department materials, Adopted Building & Construction Codes, Federal Flood Insurance Program / Flood Plain Controls, City of Decatur Planning Department materials, the Decatur Zoning Ordinance, the Subdivision Regulations of Decatur, Alabama, Historic Preservation in Decatur materials, Architectural Review Board materials, Design Review Guidelines, Certificate of Appropriateness FAQ, and related City permit applications as of May 2026.
GOVERNANCE
The City of Decatur regulates residential fence placement, height, appearance, floodplain interaction, and historic-district review through multiple code and department sources.
The City of Decatur Building Department issues construction permits for the City and administers building-code, zoning-enforcement, and floodplain-management responsibilities. The City of Decatur Planning Department administers zoning, site plan, subdivision, and Planning Commission application processes. The City of Decatur Architectural Review Board administers design review for exterior work in the Old Decatur and Albany locally zoned historic overlay districts.
The City has a specific fence and wall section in the Decatur Zoning Ordinance. Additional requirements may apply when a fence is part of a site plan, planned development, special exception, floodplain development, pool barrier, subdivision or plat matter, utility easement, right-of-way issue, or historic-overlay project.
PERMIT AND APPROVAL REQUIREMENTS
• Local Fence Permit: City of Decatur does not publish a local fence permit requirement for standard residential fences in the official source materials reviewed for this page.
• Building Department Materials: The City of Decatur Building Department publishes residential building, accessory structure, flood development, swimming pool, and swimming pool barrier permit materials, but those materials do not identify a standalone permit application for an ordinary residential yard fence.
• Accessory Structure Application: The City’s accessory-structure permit application references accessory structures under Section 25-4.3.3. Standard residential fences are regulated separately through Section 25-5.5, Fence and Wall Standards.
• Zoning Compliance: Building permit requirements are separate from zoning, setback, or plat requirements. Confirm any applicable zoning conditions, setbacks, and plat requirements with City of Decatur Planning Department before construction.
• Fence and Wall Standards Review: The Decatur Zoning Ordinance states that review for fence and wall compliance occurs during review of applications for a planned development district, special exception permit, or major or minor site plan, as appropriate.
• Historic Overlay Approval: Exterior work in the Old Decatur and Albany historic overlay districts requires an approved Certificate of Appropriateness before work starts. The City identifies fences as work reviewed by the Architectural Review Board; routine or rear-fence work may be eligible for staff review, while front-yard fence and wall work is reviewed through the historic-review process.
• Floodplain Approval: The City publishes a Flood Development Permit for man-made changes in a special flood hazard area. Where fence work is floodplain development, new and replacement fences may be allowed only if they do not act as a flow boundary, redirect flow, collect flood debris, cause blockages, cause localized flood-level increases, or become damaging debris.
• Pool Barrier Permit: The City publishes a Swimming Pool Barrier Permit Application for pool barriers installed under 2009 IRC Appendix G. This is a pool-barrier approval and is not a general residential yard-fence permit.
FENCE PLACEMENT RULES
• Private Property and Rights-of-Way: Fences and walls must be located outside the public right-of-way.
• Property Lines: Fences and walls are allowed on the property line between two or more privately owned lots, and may be located within any minimum setback.
• Utility Easements: Fences located within utility easements require written authorization from the easement holder or the City, as applicable. The City is not responsible for damage to, repair of, or replacement of fences that must be removed to access utility easements or facilities.
• Drainage: Fences and walls must not block or divert natural drainage flow onto or off of any land.
• Fire Protection Access: Fences and walls must not prevent immediate view of, or access to, fire hydrants or other fire-fighting water supply devices.
• Building Access: Fences and walls must not block required access to a building from a window or door.
• Visibility Areas: Fences and walls must not be located in a visibility triangle.
• Flood Hazard Areas: New and replacement fences in flood hazard areas may be allowed only where they do not redirect flood flow, collect debris, cause blockages, cause localized flood-level increases, or become damaging debris.
• Historic Overlay Districts: In the Old Decatur and Albany historic overlay districts, fence placement is reviewed for its effect on the property, streetscape, and district character through the Certificate of Appropriateness process.
• Plat and Boundary Context: Recorded plats, easements, rights-of-way, and survey markers may affect fence placement. The Subdivision Regulations of Decatur, Alabama include plat and survey-marker requirements for subdivision matters, but do not create an ordinary residential fence setback from property lines.
• Utility Safety: Alabama law requires notice through Alabama 811 before excavation where Alabama’s underground damage-prevention law applies. For fence projects that involve digging, including fence post holes, notice generally must be given within 2 to 10 full working days before excavation begins, not counting the day of notification.
FENCE HEIGHT AND VISIBILITY RULES
• Standard Residential Height Limits: For fences or walls located in a minimum setback in districts other than industrial districts, the maximum height is 4 feet in a front yard, 6 feet in a side yard adjacent to a street, and 6 feet in a rear yard or side yard not adjacent to a street.
• Posts and Columns: Supporting columns or posts may be taller than the maximum allowed fence or wall height if they do not extend more than 18 inches above the top of the fence or wall.
• Community Gardens: Fences and walls up to 8 feet high are allowed for community gardens.
• Visibility Triangle: The visibility triangle is measured between 2.5 feet and 8 feet above street grade at an intersection and is determined by points 25 feet from the intersection right-of-way lines, connected by a straight line. Fences and walls are not allowed in the visibility triangle.
• Historic Overlay Height Limits: In the Old Decatur and Albany historic overlay districts, the Design Review Guidelines state that fences in front and side yards must not exceed 3 feet, while back yards and other areas not readily visible may have fences up to 6 feet.
• Historic Privacy Fence Placement: In the historic overlay districts, privacy fences at back yards should begin no further forward than half the depth of the principal structure, including the porch.
MATERIAL AND CONSTRUCTION LIMITS
• Allowed Materials: The Decatur Zoning Ordinance allows fences and walls made of masonry, concrete, stone, painted wood, pressure-treated wood, rot-resistant wood, metal, vinyl, composite materials designed to appear as wood, metal, or masonry, walls clad with substrate material intended to support living vegetation, and chain link, unless another applicable rule is more restrictive.
• Prohibited Materials: Barbed wire and razor wire are prohibited unless approved through a security exemption plan, used on land with an agricultural use, or used with high-voltage utility substation equipment. Fences made of chicken wire, corrugated metal, fabric materials, fiberboard, garage door panels, plywood, rolled plastic, sheet metal, debris, junk, or waste materials are prohibited unless the materials are recycled and reprocessed for sale as new-looking building materials.
• Electric Fences: Above-ground fences carrying electrical current are prohibited except for enclosing livestock or domestic animals in the AG and RS-E districts. Below-ground electrical fences for keeping pets are not prohibited by the fence section.
• Finished Side: If one side of a fence or wall is more finished than the other, the more finished side must face the exterior of the lot.
• Building Code: Fences and walls must comply with applicable building-code requirements.
• Gates: Unattended gates and gates opening onto a public sidewalk area must be self-closing, self-latching, and locked when not in use.
• Security Exemption Plan: A landowner with a heightened security need may submit a security exemption plan proposing a taller fence or wall, or barbed wire, razor wire, or electric wire atop a fence or wall. Approval depends on the Director’s findings under the security-exemption standards.
• Historic Overlay Materials: In the Old Decatur and Albany historic overlay districts, wood picket or metal fences are appropriate in front yards and side yards in public view. Wire, chain-link, vinyl, horizontal rail, stockade, wood plank, solid brick, and open-weave brick fences are not appropriate in public view under the Design Review Guidelines, though some utilitarian materials may be installed in rear yards and side yards not readily visible.
• Historic Fence Orientation: In the historic overlay districts, privacy and picket fences should have the structural framework on the inside of the fence, not facing the street.
• Retaining Walls: Retaining walls are exempt from the City’s general fence and wall standards, but historic retaining walls in the historic overlay districts are reviewed under the Design Review Guidelines and should be preserved.
PRIVATE RESTRICTIONS
Private covenants, deed restrictions, easements, and homeowners’ association rules operate independently from City fence regulations. They may impose fence limits that are more restrictive than City standards.
The City of Decatur does not monitor or enforce private covenants, deed restrictions, or private agreements. A fence that satisfies City requirements may still be limited by a recorded plat, easement, HOA rule, or private covenant.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Fence and Wall Standards: Construction or replacement of fences and walls is measured against Section 25-5.5, Fence and Wall Standards, unless the fence or wall is exempt from that section.
• Site or Development Review: Fence and wall compliance is reviewed during planned development district, special exception permit, or major or minor site plan review when those processes apply.
• Historic Review: Fence work in the Old Decatur and Albany historic overlay districts is reviewed through the Certificate of Appropriateness process administered by the Architectural Review Board or staff, depending on the scope and location of the work.
• Floodplain Review: Fence work in a special flood hazard area is reviewed for floodplain-development compliance and for whether the fence could redirect flow, collect debris, cause blockages, increase flood levels, or become damaging debris.
• Visibility Review: Fences and walls are reviewed for visibility-triangle conflicts at intersections.
• Right-of-Way and Easement Review: Fences and walls are reviewed for public right-of-way encroachment and utility-easement authorization where those conditions apply.
• Drainage and Fire Access: Fences and walls are reviewed for drainage diversion, fire hydrant visibility and access, and required building access from windows or doors.
• Pool Barrier Review: A fence used as a swimming-pool barrier is reviewed through the City’s swimming-pool barrier process and the applicable pool-barrier standards.
