What is the difference between a regulatory and an informational parking sign?

Regulatory signs cite code (MUTCD R-series, ADA Std 502, NFPA 1) and the wording is mandatory. Informational signs are property-owner choices and the wording is fully customizable. Regulatory signs carry inherent enforcement; informational signs need a paired tow-warning addendum to give tow authority on private property in Oregon.

Do I need an ADA sign on every accessible stall?

Yes. ADA Std 502.6 requires every accessible parking space to be identified by a sign with the International Symbol of Accessibility, mounted with the bottom of the sign at least 60 inches above the pavement. Pavement striping alone does not satisfy the identification requirement.

Can I make my own custom parking signs?

On private property, yes. MUTCD applies on public roadways, not private lots. Custom signs work for visitor, employee, and tenant designations. Anything that touches code (ADA, fire-lane, tow-away) should follow the standard legend so enforcement and audits are clean.

What size are most parking lot signs?

The default is 12 x 18 inches for ADA, no-parking, reserved, and visitor signs. 18 x 24 inches is the upsize for tow-away, fire-lane, and long-sightline lots. 24 x 30 inches gets used on freeway-adjacent retail and very large industrial yards.

How are MUTCD R-series codes assigned?

The Federal Highway Administration publishes the codes in the MUTCD. R7 series covers parking; R8 covers parking restrictions; R10 covers EV and special-use parking. State DOTs can publish state-variant codes (Oregon's R7-201 is a state-specific accessible-parking sign). Both federal and state-variant codes are acceptable on private property in Oregon.

Parking Sign Types: Regulatory vs Informational vs Prohibitive

Parking lot signs split into four working types: regulatory (MUTCD R-series with code-driven wording), informational (visitor, employee, reserved), prohibitive (tow-away and no-parking), and fire/life-safety (fire-lane and emergency access). Property owners pick by enforcement need, jurisdiction, and traffic volume. The federal MUTCD R-series governs every regulatory legend.

Why Does Sign Type Matter for Property Owners?

The wrong sign type voids enforcement. A "Customer Parking Only" sign, no matter how well-printed, will not give an Oregon tow contractor authority to remove a vehicle. A 12 x 18 inch fire-lane sign in red-and-white but with the wrong post spacing will not satisfy a fire-marshal inspection. Knowing which type to spec for which job is the first step in a working signage plan.

What Are Regulatory Parking Signs?

Regulatory signs invoke federal or state code. They are mandatory wherever the regulation applies and the wording is not negotiable.

How Does the MUTCD R-Series Work?

The Manual on Uniform Traffic Control Devices is published by the Federal Highway Administration and assigns every regulatory sign a code. The R-series covers regulatory parking and traffic-control. Common codes for parking lots:

Code	Legend	Standard Size
R7-1	No Parking Any Time	12 x 18 in
R7-2	No Parking [Time Period]	12 x 18 in
R7-8	Reserved Parking + International Symbol of Accessibility	12 x 18 in
R7-8a	Van Accessible	6 x 12 in (add-on)
R7-201	Reserved Parking Handicap (state variant)	12 x 18 in
R8-3	No Parking This Side	12 x 18 in

State-variant codes (R7-201 in Oregon, R99-X in California) differ from the federal R7-8 only in legend wording and color field. Either is acceptable on private property in Oregon as long as the legend is unambiguous and the International Symbol of Accessibility appears on the panel.

What Does ADA Standards 502 Require?

ADA Std 502.6 sets two binding rules for any accessible-stall identification sign:

The bottom of the sign must sit at least 60 inches above the pavement.
Vans get a "Van Accessible" placard either as integrated wording or as the R7-8a add-on.

ADA Std 703 sets character-height minimums for signs that designate a permanent room or space; for parking applications the practical effect is that the legend must use legible character heights and an accessible color contrast.

For broader stall-count and aisle requirements, see ADA parking requirements Oregon. This sign-type article focuses on what wording and what code to put on the panel; that companion article covers how many stalls a property has to have in the first place.

What Are Informational Parking Signs?

Informational signs guide drivers without invoking code. They are fully customizable.

Visitor Parking -- assigns short-term spaces to non-tenants. Common at offices and apartment complexes.
Customer Parking Only -- retail intent. Tells drivers the lot is not municipal parking.
Reserved (numbered) -- tenant assignment. Each placard carries a unit or stall number.
Employee Parking -- shifts staff out of customer-facing stalls.
EV Charging Only -- often paired with the MUTCD R10-series green pump symbol.
Permit Parking -- multi-family or office park requiring sticker validation.

These signs are useful precisely because they are not code-bound; the property owner can word them to fit the site. The trade-off is that without an accompanying tow-warning addendum, a tow contractor in Oregon will not lawfully tow a vehicle parked in violation.

What Are Prohibitive Signs and When Do You Need Them?

Prohibitive signs threaten consequence. They are the enforcement layer that gives informational signs their teeth.

What Does a Tow-Away Sign Have to Say?

In Oregon, ORS 98.812 sets the language requirements for a property owner to lawfully authorize private-property towing. The sign must include:

Notice that vehicles parked in violation will be towed.
The phone number of the tow company that will perform the removal.
Posting at every entrance and at intervals visible from any stall.

A tow-away sign that omits the tow company contact number does not give legal authority for removal, even if every other element of the sign is compliant. On a 14,000 sq-ft Springfield apartment property where Cojo replaced 24 perimeter signs in March 2026, four of the prior owner's tow-away signs lacked a phone number and the tow contractor had refused service for three months until we re-signed the lot.

What About No-Parking and Tow-Zone Signs?

R7-1 ("No Parking Any Time") is the federal code. On a private lot, the legend can be paired with a tow-warning add-on or printed on a single panel that combines both legends. The standard install pattern is a 12 x 18 inch primary sign with a 6 x 12 inch tow-warning addendum directly below.

What Are Fire and Life-Safety Signs?

Fire-lane signs sit in their own bucket because NFPA 1 Section 18.2.3.5.1 and the International Fire Code Section 503.3 -- both adopted by most Oregon jurisdictions -- mandate dimensions, color (red on white or white on red), and posting density.

Spec	Fire Lane Sign Requirement
Minimum panel size	12 x 18 inches
Color	Red on white
Mount height	4 to 7 feet to bottom of sign
Posting interval	Every 50 feet, both ends, mid-lane

Fire-lane curb striping is the partner element to the sign. We pair every fire-lane sign install with a curb-paint refresh on the same crew visit because Oregon Fire Marshal inspectors flag uncoordinated marking and signage as a single deficiency.

How Do You Pick the Right Type for Your Lot?

Three quick questions usually settle the spec:

Is the sign tied to a code? -- If yes (ADA, fire-lane, public-ROW), use the regulatory category and the matching MUTCD R-code or NFPA spec.
Does the sign need tow authority? -- If yes, pair an informational legend with an Oregon ORS 98.812-compliant tow-warning addendum.
What is the visibility distance? -- Long sightline lots get 18 x 24 inch panels; standard interior lots get 12 x 18 inch.

Industry Baseline Range

Sign Type	Per-Sign Range	Installed (sign + post + footing)
ADA R7-8 (12 x 18 in, .080 alum, Type III)	$35 to $75	$200 to $450+
Tow-away (18 x 24 in, .080 alum, Type III)	$55 to $110	$250 to $550+
Fire-lane (12 x 18 in, .080 alum, Type IX diamond)	$65 to $130	$275 to $600+
Informational (custom 12 x 18 in)	$30 to $80	$200 to $450+

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

Mixed sign packages on apartment and retail re-signs run 18 to 30 percent above 2022 baselines. Anti-graffiti laminate availability and tamper-proof hardware tariffs have hit the per-panel cost the hardest. Crew-time pricing for two-person install teams in the Willamette Valley has moved up alongside fuel.
