A 15-minute parking sign restricts curbside or stall parking to 15 minutes maximum, used at high-turnover pickup zones (curbside food order pickup, dry cleaning, banking ATMs); a 30-minute parking sign extends the limit to medical office check-in, take-and-go retail, and short-business-call zones. Both are coded as MUTCD R7-6 with a time-limit legend, mounted at 7 feet to bottom of sign per MUTCD §2A.18, and enforced under Oregon ORS 98.812 on private property when paired with proper tow-authority signage at every entrance.
This guide breaks down when to spec 15-minute vs 30-minute signage, the math on sign density per linear foot, and the enforcement realities our crew at Cojo sees on commercial property installs across Oregon.
What's the difference between 15-minute and 30-minute parking?
Time-limit signage is the same R7-6 sign blank with different time legend. The functional difference is what the property is signaling to drivers about expected stay duration:
| Time limit | Typical use case | Vehicle turnover per stall per day |
|---|---|---|
| 15 minutes | Curbside pickup, ATM, drop-off | 25 to 40 turns |
| 30 minutes | Pharmacy, dry cleaner, check-in | 15 to 22 turns |
| 60 minutes | Quick lunch, errand, mall kiosk | 8 to 12 turns |
| 2 hour | Standard customer parking | 4 to 6 turns |
| 4 hour | All-day patron | 2 to 3 turns |
| Unlimited | General customer / tenant parking | 1 to 2 turns |
When does 15-minute signage make sense?
15-minute parking is the right spec when:
- Service is genuinely under 15 minutes (curbside food order pickup, ATM transaction, mailbox visit)
- Stall turnover is critical for customer access (Saturday lunch rush, Friday night ATM use)
- The property has a curb-and-go pattern (most pickup-from-storefront retail)
- Volume of short-stay customers exceeds the spaces available
15-minute zones are common at:
- Coffee shop curbside pickup (Starbucks, Dutch Bros pickup signs run 15 minute)
- Dry cleaner drop-off
- Bank ATM
- Mailbox / package locker
- School-pickup loops (10 to 15 minute)
The legibility math is the same as any R-series sign -- 1 inch of letter height per 30 feet of expected reading distance per MUTCD §2A.13. For a 12 by 18 R7-6 sign at 60 feet viewing distance, 2 inch primary letter height ("15 MIN PARKING") with 1.5 inch secondary line ("VIOLATORS TOWED") is the standard.
When does 30-minute signage make more sense?
30-minute parking is the right spec when:
- Typical service or appointment duration is 15 to 25 minutes (no padding for under)
- The property serves customers with brief but variable check-in time (medical offices, urgent care, pharmacy)
- 15-minute would frustrate customers who legitimately need 18 to 22 minutes
- Volume is lower than 15-minute zones but higher than 60-minute zones
30-minute zones are common at:
- Pharmacy and prescription pickup
- Dry cleaner pickup with item retrieval
- Medical office check-in zones
- Bank teller (in-branch transactions, not ATM)
- Take-and-go restaurant orders
What does the MUTCD R7-6 sign actually look like?
R7-6 is the time-restriction parking sign in the FHWA Standard Highway Signs tables. The legend reads "[X] MINUTE PARKING" with optional supplementary lines. Common layouts:
- "15 MIN PARKING -- 8 AM to 6 PM" (time-of-day restricted)
- "30 MIN PARKING -- VIOLATORS TOWED PER ORS 98.812"
- "15 MIN PARKING -- CUSTOMER ONLY" (private-property variant)
Background color is white, legend color is black. Supplementary tow-warning language is typically in red on the same sign or on a separate sign mounted directly below. ASTM D4956 Type III HIP minimum sheeting grade is best practice for outdoor enforceability.
How dense should time-limit signage be?
Sign density math depends on lot configuration:
- Curbside row of 6 to 8 stalls. One R7-6 at the head of the row, mounted on a 7 foot post. Visible from every stall in the row.
- Row of 12 to 15 stalls. Two R7-6 signs, one at the head and one at the midpoint or tail.
- Drive-thru curbside zone. One sign at the entry, one at the exit. Yellow curb paint along the entire zone length.
- Multi-row time-restricted area. One sign per row at minimum.
The MUTCD default for sign-spacing is 50 feet maximum on regulatory signs. Tighter spacing (25 to 30 feet) is recommended at commercial properties where short-stay turnover is critical.
How does enforcement actually work on private property?
Time-limit signs on private property are enforced under ORS 98.812 tow authority, not by ticket. Practical enforcement requires:
- The R7-6 time-limit sign at the head of the row (or curbside zone)
- A primary "PRIVATE PROPERTY" sign at the property entrance with tow-authority language
- A property-management staff member or third-party enforcement contractor monitoring duration
- Photo documentation of the violating vehicle's arrival time and duration
Most commercial properties use third-party enforcement contractors (chalk-and-tow services or LPR-camera providers) for time-limit enforcement. The signage is necessary but not sufficient -- enforcement requires monitoring infrastructure.
Industry Baseline Range
| Component | Cost per sign / per zone |
|---|---|
| 12 x 18 R7-6 15-minute sign HIP Type III | $34 to $52 |
| 12 x 18 R7-6 30-minute sign HIP Type III | $34 to $52 |
| 18 x 24 R7-6 with time-of-day restriction and tow language | $58 to $96 |
| Custom legend screen-print | $14 to $28 per sign upcharge |
| Sign post and footing (installed) | $244 to $410 |
| Full curbside time-limit zone (3 signs + 70 ft curb paint) | $940 to $1,640 |
Current Market Reality
Custom screen-print pricing for time-limit legends has stabilized at minimum order quantities of 4 to 6 units. Reflective sheeting climbs of 4 to 6 percent annually flow through. The biggest cost driver on time-limit signage is sign density -- a 14-stall curbside drive-thru zone needs 3 to 4 signs vs the 1-sign default for a non-time-restricted zone, which roughly triples the per-zone signage budget.
Real install reference -- Beaverton coffee drive-thru
In February 2026, our crew installed time-limit signage at a Beaverton coffee shop with curbside pickup. The owner had been losing weekend morning sales to all-day office workers parking in the curbside spots and walking inside.
Spec we delivered:
- 4 R7-6 15-minute signs at 12 x 18 HIP Type III along the 6-stall curbside row
- 7 foot post-mount on hot-dip galvanized 2.375 inch round posts
- 1 supplementary "CUSTOMER PICKUP ONLY -- VIOLATORS TOWED PER ORS 98.812 -- Acme Towing 503-555-1234" sign at the entry to the curbside row
- 60 linear feet of green curb paint identifying the time-restricted zone
- 6 pavement stencils reading "15 MIN" at the head of each stall
Total project: $1,640 installed. The owner contracted with a third-party LPR-camera enforcement provider for daily monitoring. Average curbside-stall turnover went from 4 to 6 turns per day pre-install to 22 to 28 turns per day post-install.
Common time-limit signage mistakes
- Posting time-limit signs without ORS 98.812 tow-authority signage at the property entrance. Tow contractors will not enforce.
- 15-minute restriction at a property where service genuinely takes 20 to 25 minutes. Drives customer complaints and erodes goodwill.
- Engineer-grade Type I sheeting on outdoor time-limit signs at curbside zones. Faded by year 5 to 7.
- Single sign for a 14-stall row. Drivers in the middle and end stalls miss the sign.
- Time-of-day restriction with secondary letter height under 1.5 inches. Unreadable from the typical decision distance.

15-minute vs 30-minute parking sign FAQ
Should I use 15-minute or 30-minute parking at my coffee shop drive-thru? 15-minute for standard curbside pickup at a coffee shop. The typical service time from order ready to customer pickup is under 5 minutes, and 15 minute restriction maintains the 25 to 40 turns per day that justify the curbside zone. 30 minute is appropriate at coffee shops with sit-and-work seating but not for pickup zones.
Are time-limit parking signs legally enforceable in Oregon? Yes on private property when posted with compliant signage and paired with ORS 98.812 tow-authority signage at the property entrance. The sign alone is not enforcement -- the property must have monitoring infrastructure (staff, chalk-and-tow contractor, or LPR camera) and a tow contract with a licensed Oregon tow contractor.
What does R7-6 mean on a parking sign? R7-6 is the MUTCD code for time-restriction parking signs. The legend includes the time limit ("15 MINUTE PARKING," "30 MINUTE PARKING") and optional supplementary lines for hours-of-day restrictions and tow-warning language. The R7-6 sign blank itself is white background with black legend, 12 by 18 inches conventional minimum.
Do time-limit parking signs need to be reflective? ASTM D4956 Type III HIP minimum is best practice. Faded sheeting that drops below FHWA minimum maintained retroreflectivity weakens enforceability. Engineer-grade Type I is acceptable for indoor parking-garage time-limit signage but not for outdoor zones.
How many time-limit signs do I need on a 12-stall curbside row? Two minimum -- one at the head of the row and one at the midpoint or tail. Some Oregon municipalities recommend tighter 25 to 30 foot spacing. The MUTCD default is 50 foot maximum sign-to-sign spacing on regulatory signs.
