No Parking Stencil Spec: 24-48 Inch Letter Height for Private Lots

No Parking Stencil Spec for Private Lots

A NO PARKING legend painted on the asphalt is a precise compliance tool, not decoration. The federal letter-height rule lives in MUTCD Section 3B.20, and Oregon's tow-enforceability statute (ORS 98.812) ties the pavement word to the vertical sign that lets a property owner actually move an offending vehicle. Stencil kits that match the federal pattern and the state wording produce legends that hold up in both a code-cycle review and a tow dispute.

What Is a No Parking Stencil and When Should I Use One?

A NO PARKING stencil is a reusable LDPE cutout (1/16-inch or 1/8-inch thickness) used to apply the words NO PARKING -- often paired with TOW AWAY ZONE or FIRE LANE -- on parking-lot pavement using traffic paint. Standard private-lot installations use 24- to 48-inch letter heights per MUTCD Section 3B.20. The pavement word is paired with a vertical R7-1 or fire-lane sign and red curb paint to complete the enforcement package. Cojo installed 9 NO PARKING legends on a Eugene apartment-complex fire-lane perimeter in February 2026 using 24-inch reusable LDPE letters and a 6-pound-per-gallon glass-bead drop.

What Letter Height Does MUTCD Specify for NO PARKING?

The FHWA MUTCD Section 3B.20 sets pavement word letter heights based on roadway speed. For private parking-lot conditions:

Posted speed / context	MUTCD letter height	Common use
5 to 10 mph (slow lot interior)	24 in to 36 in	Loading zones, employee-only restrictions
10 to 15 mph (drive lanes, fire lanes)	36 in to 48 in	Fire-lane perimeters, tow-away zones
15 mph or higher (lot exit drives)	48 in or larger	High-visibility tow-away near public ROW

A 24-inch letter holds legibility from approximately 60 feet at 5 to 10 mph; a 48-inch letter reads past 100 feet. Letter height beyond what the federal pattern requires only adds paint volume.

Where Should NO PARKING Legends Be Placed?

Cojo applies NO PARKING legends at these locations:

• Fire-lane perimeters. Per NFPA 1 Section 18.2.3.5 the fire lane needs continuous identification; pavement legends on 50- to 80-foot intervals reinforce the painted curb and signage.
• Loading zones and dumpster pads. A NO PARKING -- LOADING ZONE legend with time-restricted signage gives a tow operator the documentation chain.
• ADA access aisles. Diagonal hatching marks the aisle as no-park, but a NO PARKING pavement word at the head of the aisle reinforces the cue (per ADA Standards 502).
• Driveway approaches and emergency-vehicle access. A NO PARKING legend within 15 feet of any building exit door supports egress code requirements.
• Tenant-only enforcement at multifamily entrances. Combined with a TOW AWAY ZONE legend and ORS 98.812 signage.

How Does the NO PARKING Pavement Word Tie into Tow Enforcement?

Oregon Revised Statute 98.812 governs private-property tow authority. The statute requires a posted sign with specific wording before a property owner can have a vehicle towed at the registered owner's expense. A pavement NO PARKING legend on its own does not authorize a tow -- the tow chain runs:

1. Vertical R7-1 or TOW AWAY ZONE sign meeting ORS 98.812 wording requirements
2. Posting at every entrance and at intervals visible from any parked stall
3. Pavement-level reinforcement (NO PARKING legend, red curb, fire-lane stencil)
4. Photographic documentation of the violation
5. Tow contractor with a current state permit

The pavement legend is the visual reinforcement layer. It speeds up driver compliance, reduces "I didn't see the sign" disputes, and gives the tow contractor visible evidence in the photo record.

What Paint Thickness for a NO PARKING Pavement Word?

• Wet film thickness: 16 to 25 mil for water-based traffic paint
• Dry film thickness: 8 to 13 mil water-based; 90 to 125 mil thermoplastic
• Glass-bead drop: 6 to 8 pounds per gallon, AASHTO M247 Type 1, applied while wet
• Cure time: 30 to 90 minutes to traffic-tracking-safe at 65 to 80 degrees F

The bead drop matters most on fire-lane perimeters because the cue must read at any hour. A NO PARKING legend that fades to a daylight-only mark at 18 months is below industry standard for a fire-lane installation.

What Color Should a NO PARKING Pavement Word Be?

Color choice depends on what the legend pairs with:

• White paint on dark asphalt for general no-park zones (employee-only, loading zone). Highest visibility, MUTCD-pattern.
• White on red curb-painted background for fire-lane perimeters. The red curb communicates fire-lane status; the white legend confirms it. OSHA's red-paint reference at OSHA 1910.144(a)(1) governs marshaling and demarcation, not parking-lot fire lanes specifically, but the red-curb convention is universal.
• Yellow on dark asphalt is sometimes used for warning-only no-park areas (caution legends). Yellow is non-standard for pure NO PARKING and can confuse drivers who associate yellow with caution-lane-divider markings.

What Does a NO PARKING Stencil Cost?

Industry Baseline Range

Component	Spec	Cost
Reusable LDPE NO PARKING stencil (24 in letters)	1/8 in	$130 to $260
Reusable LDPE NO PARKING stencil (36 in letters)	1/8 in	$200 to $380+
Reusable LDPE NO PARKING stencil (48 in letters)	1/8 in	$280 to $520+
Combined NO PARKING + TOW AWAY ZONE kit	1/8 in	$320 to $620+
Water-based paint per pavement word	16 to 25 mil wet	$18 to $45
Labor per pavement word (paint, on existing prep)	Field	$45 to $120+
Red curb paint adjacent (per linear foot)	Painted	$2 to $5+

These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.

Current Market Reality

Fire-lane NO PARKING work usually batches into a fire-lane perimeter contract with red curb paint and signage. Stand-alone NO PARKING call-outs (a single legend at a complaint location) run 30 to 50 percent above the per-legend baseline because mobilization recovers across one or two pavement words. 2026 traffic-paint and LDPE-resin costs tracked 6 to 12 percent above 2025; thermoplastic preformed legends pushed higher on petroleum feedstock.

Real-World Cojo Install: Eugene Apartment Complex Fire Lane

On a 38,000-square-foot Eugene apartment complex in February 2026, Cojo installed 9 NO PARKING legends along a fire-lane perimeter on 60-foot intervals. We used 1/8-inch LDPE stencils with 24-inch letter height, white traffic paint at 18-mil wet, and a 6-pound-per-gallon glass-bead drop. Pavement words paired with red curb paint (12-inch face strip) and 6 vertical R7-1 fire-lane signs at perimeter entrances. The complex's annual fire-marshal inspection cited zero pavement-marking deficiencies in the year following installation.

Combined Legends: NO PARKING + TOW AWAY + FIRE LANE

For high-enforcement zones, multi-line legends communicate the full enforcement chain at pavement level:

• NO PARKING -- TOW AWAY ZONE. Multifamily and apartment-complex tenant-only enforcement.
• NO PARKING -- FIRE LANE. Fire-lane perimeter, paired with red curb and R7-1 sign.
• NO PARKING -- LOADING ZONE. Time-restricted dock or curb space, paired with time-restriction sign.

Multi-line legends use stacked stencil kits that maintain MUTCD letter-height and stroke-width pattern through both lines. Stencil suppliers who CNC-cut to MUTCD Figure 3B-22 produce kits where stacked lines align without manual offset.

Pair the Pavement Word with Sign and Curb for a Complete Enforcement Package

A NO PARKING pavement word on its own is a visual cue, not a tow trigger. The tow happens because a vertical sign meeting ORS 98.812 wording, a painted curb at the parked-on edge, and the pavement word together build the documentation chain a tow operator and an insurance argument can stand on.

Cojo applies MUTCD-pattern NO PARKING legends as part of every fire-lane and tow-zone scope of work. Contact Cojo for a no-parking enforcement package on your property.
