Fence, Gate and Retaining Wall CAD Blocks

Fence, gate, retaining wall, storage shed, mailbox and bike rack - six site CAD blocks that define a property's edges and the small structures along them. The fence and retaining wall are linear and get arrayed along a run; the shed, mailbox and rack are single placements. All are free DXF downloads.

Fence

Site / Exterior - datum: near-left (start), runs +X - default footprint 241in x 2in

Fence - plan view CAD block
Fence - plan view, 241in x 2in

Straight fence run with post ticks, for property lines, yard enclosures, and screened equipment yards on site plans. Its purpose on the sheet is showing enclosure extents and where gates interrupt the run.

Sizing

Default 240in (20ft), adjustable 24-2400in - from a 2ft screen return to a 200ft property side in a single insert. The posts toggle switches individual post symbols off, which is the right call on a long boundary run or a schematic where post ticks would clutter the plot.

Drafting notes

It starts at the near-left end and runs +X, so lay it out from a corner monument or building corner and rotate each segment onto its property bearing. At 2in of bbox depth it plots as a line weight rather than an area - do not hatch it.

Drawn alongside

Broken by the gate block wherever access is needed, and stepped against the retaining wall where the grade changes.

Gate

Site / Exterior - datum: hinge post (near-left) on fence line - default footprint 50in x 42.57in

Gate - plan view CAD block
Gate - plan view, 50in x 42.57in

Swing gate with the leaf sweep shown, inserted where a fence run breaks for a walk or drive. The arc is the working part of the symbol - it proves the leaf clears a walk, a slope, or a parked car.

Sizing

Default 48in, adjustable 36-144in, which spans a pedestrian walk gate up to a double drive gate. Past roughly five feet of leaf, a single swing gets heavy on its hinges and is commonly split into a pair rather than drawn as one panel.

Drafting notes

The hinge post on the fence line is the datum, so mirroring the block flips the swing hand without relocating the hinge. The 50in bbox width carries 2in past the 48in leaf for the hinge and latch posts, and the 42.6in Y extent is swept arc geometry, not a physical footprint - never carry a dimension off it.

Drawn alongside

Drawn into the fence run it interrupts, and at pool enclosures where the barrier gate is a code-scoped element.

Where the fence serves as a pool barrier, the International Swimming Pool and Spa Code addresses the gate: swing direction, latch position, and self-closing and self-latching hardware.

Retaining Wall

Site / Exterior - datum: near-left corner (runs +X) - default footprint 240in x 18in

Retaining Wall - plan view CAD block
Retaining Wall - plan view, 240in x 18in

Wall in plan holding a grade change - terraced yards, driveway cuts, planter walls. Civil and landscape drafters draw it to carry top-of-wall and bottom-of-wall elevations that the structural sheet keys off. Jurisdictions commonly set an unbalanced-fill height above which an engineered design is required.

Sizing

Default 240in (20ft) long, 12in thick; length adjusts 48-2400in and thickness 8-36in. Thickness tracks the wall system - roughly 8in for a small segmental block unit, 36in for a mass-gravity section or a cantilever stem drawn with batter.

Drafting notes

The near-left corner is the datum with the wall running +X, so segments chain end to end for stepped and terraced runs. The 18in bbox depth exceeds the 12in thickness, meaning the block carries 6in of geometry behind the wall face.

Drawn alongside

Drawn with a fence along the top of wall and with the deck or patio the wall is holding up.

Storage Shed

Site / Exterior - datum: near-left corner - default footprint 96in x 120in

Storage Shed - plan view CAD block
Storage Shed - plan view, 96in x 120in

Detached accessory storage structure on residential site plans. It is drawn primarily to test setback compliance and lot coverage, since a shed is often the thing that pushes a small lot past its accessory-structure allowance.

Sizing

Default 96in x 120in, a common 8ft x 10ft prefab. Both dimensions adjust 48-240in, covering a 4ft lean-to up to a 20ft x 20ft outbuilding. Two hundred square feet is the figure the model residential code uses for its permit exemption - the 80sf default sits well under it, the 400sf maximum well over.

Drafting notes

Near-left corner datum. Setback dimensions run straight from the block edge to the property line, but the outline is the wall footprint with no eave projection, and setbacks are frequently measured to the eave - add that overhang separately if the reviewer measures it that way.

Drawn alongside

Drawn with the fence enclosing the rear yard and with the driveway or a walk providing the access path to it.

Relevant standards

International Residential Code (IRC)
The permit-exemption list addresses one-story detached accessory structures used as tool and storage sheds below a floor-area threshold. Jurisdictions amend the threshold routinely, so it is a starting point, not an answer.

Mailbox

Site / Exterior - datum: post center - default footprint 12in x 7.2in

Mailbox - plan view CAD block
Mailbox - plan view, 12in x 7.2in

Curbside post-mounted box for residential plot and landscape plans, set at the driveway and curb interface. It gets drawn mostly to keep the box clear of a driveway flare, a street tree, or a utility pedestal.

Sizing

Default 12in diameter with a 7.2in bbox depth for the box body on its post; the 8-18in range runs from a small standard box to an oversized or locking parcel box. Postal service placement guidance, not the box size, usually sets where it lands.

Drafting notes

Post center is the datum, so it snaps to a station offset from the curb face. At 1in=20ft a 12in box plots at about a twentieth of an inch on the sheet, so it normally takes a leader note rather than a dimension string.

Drawn alongside

Drawn beside the driveway apron and the sidewalk, since all three compete for the same few feet of parkway.

USPS curbside mailbox requirements
The Postal Service, not the building code, publishes the construction and placement requirements for curbside boxes, including height above the road surface and setback from the curb face. Confirm with the local post office before dimensioning.

Bike Rack

Commercial Office - datum: near-left base - default footprint 50in x 6.53in

Bike Rack - plan view CAD block
Bike Rack - plan view, 50in x 6.53in

Loop-style bicycle rack shown in plan on site plans and ground-floor architectural plans. Landscape architects and site designers place it near building entries, transit plazas, and interior bike rooms, usually to satisfy a zoning bicycle-parking count.

Sizing

The default three loops at 24in spacing produce a 50in run in a 6.5in-deep band. Spacing adjusts 18-36in and loops 1-10, so a single insert covers a two-bike entry rack or a ten-loop bank. APBP guidance puts rack elements on roughly 30in centers where two bikes are meant to share one element; the 18in end of the range packs elements tighter and in practice yields one bike each.

Drafting notes

The near-left base datum seats the block against a curb line or wall face and lets it array cleanly along +X at whatever spacing the plan calls out. Site-furnishings layer, typically plotted at 1/8in or 1in=20ft.

Drawn alongside

Drawn alongside bollards and sidewalk runs, since bike parking nearly always lands on a paved walk edge that needs protection from vehicle overrun.
