Most property managers believe a covered parking structure should be subject to the same fire code as a parking garage. However, this is not the case, especially for the freestanding carports most apartment communities in Carolina actually build. According to NFPA 88A, the Standard for Parking Structures, the standard does not apply to a free-standing, one-story covered structure that is open on at least two sides and offers shelter and storage for motor vehicles; this description fits the vast majority of the rows of aluminum and steel carports situated in apartment developments from Charlotte to Myrtle Beach. This exception has a greater impact than most property managers recognize on how a carport should be striped, since the fire access, clearance, and marking requirements that apply come from a different section of the code.
At ProLine Parking Lot Maintenance, we stripe the rows of carports in Charlotte, Raleigh, Columbia, Greenville, and in the coastal area near Charleston and Myrtle Beach, and the striping work involved with carports is actually quite different from that on an open parking lot, even if it might seem like no more than a shaded version of the same job. Carports have fixed support posts that disrupt straight lines in a way an open parking lot never has to deal with. It is normal, not exceptional, for spaces to be assigned and numbered. Also, the shade, which makes a carport valuable to residents, has an effect on the way the paint behaves as it cures. Below is a full explanation of what we consider when we stripe a carport in a Carolina apartment complex and what property managers should know before launching their next carport striping project.
Open Lot Striping vs. Carport Striping: What Actually Changes
A carport isn’t simply a covered version of a standard parking space; adding a roof structure and supporting posts changes several factors.
| Factor | Open Lot | Carport |
| Fire code classification | Falls under general fire lane and access rules | Typically excluded from NFPA 88A if freestanding and open on two-plus sides |
| Fixed obstructions | Rare, usually just light poles | Support posts at fixed intervals set by original construction |
| Space assignment | Usually first-come, first-served | Usually assigned and individually numbered |
| Paint cure conditions | Direct sun and rain exposure | Shaded, cooler surface temperature, protected from rain |
| Layout flexibility | Lines can shift to fit any redesign | Striping must work within existing post bay spacing |
| Wheel stop use | Common and straightforward | Often limited by post placement and anchor footings |
Why the Fire Code Gap Matters for How You Stripe Fire Access
Since a standard freestanding carport is not included within the scope of NFPA 88A, the fire access requirements for it are generally based on the local version of the International Fire Code that has been adopted and on the fire separation distances associated with the type of construction of the building, rather than on a standard that is specific to parking structures. In practice, this means fire lane markings along a row of carports usually must meet the general fire apparatus access requirements that apply to the rest of the property, rather than a separate clearance rule specific to the structure. We work directly with the local fire marshal’s office on any carport project, since requirements for fire separation distance and the unobstructed access a fire lane must maintain vary by jurisdiction and by how close the carport is to an occupied building.
- Before you stripe the fire lane next to the carport, check with the local fire marshal to confirm its width, since a carport near a building may need a wider or more clearly marked fire lane than an open lot in the same position.
- The fire lane striping must be fully visible from the drive aisle, since a carport roofline may create a shadow that makes standard white or yellow paint harder to read than in direct sunlight.
- You should never place carport support posts within the required fire lane clearance width because a post too close to the lane will have the same effect as a parked car by creating a functional obstruction, even though it is a permanent structure, not a vehicle.
Working Around Fixed Support Posts
When a carport is first constructed, the support posts are set in concrete at regular intervals, and the spacing between bays is generally designed to accommodate two, four, or more vehicles per row, depending on the structure’s design. Unlike an open yard, where we can move a space one foot in either direction to deal with a cramped arrangement, carport striping must conform to the original post spacing the structure was built with. Before drawing a single line, measure the distance between the posts in each bay, since spacing is not always even along an older carport row that may have settled or been repaired in sections over the years.
- Centre the spaces on their adjoining posts rather than assuming a uniform width for the entire row, since even small variations between bays add up over the length of a long carport structure.
- For the part of the space nearest each post, increase the width by 6 to 12 inches over the standard width, since a fixed post takes away the flexibility a driver would normally have to shift slightly for door clearance.
- Use reflective or high-contrast paint on the posts at ground level, along with the strips, since a post in a shaded carport is harder to see at night than the same obstruction in an open, well-lit area.
Assigned and Numbered Carport Spaces
Most apartment carports in Carolina use an assigned-parking system rather than open, first-come parking, and this difference affects the required surface area. Apart from the standard space markings, we stencil the number of the assigned unit or space directly into each car space, using bold, high-contrast letters that are large enough to be easily seen from the car’s headlights at night, the size usually being between 12 and 18 inches high depending on the carport’s lighting. Since the same vehicle parks in the same space every day, the stencil numbers wear differently than markings in an open parking lot. Oil drips and tire wear concentrate exactly in the same area every day rather than being distributed among a changing selection of vehicles, and as a result the numbers—not just the boundary lines—tend to fade or stain more quickly in the middle of the space than at the sides.
Paint Cure Time Works Differently Under a Roof
The shade provided by a carport benefits residents and their vehicles, but it also affects how striping paint sets. The speed at which traffic paint cures is determined by the temperature of the pavement surface, and since the surface of a carport is noticeably cooler than that of an open area exposed to the direct sunlight of Carolina’s summer, evaporation is slowed down and the time available before the paint is completely free of tracks is extended. On the positive side, a carport eliminates rain as a scheduling factor, because unlike on an open lot during a Carolina summer, we aren’t having to race against an afternoon thunderstorm. The drawback, however, is airflow; an open lot benefits from a breeze that aids the evaporation of solvents, whereas a carport, particularly one that is enclosed on three sides, can trap warm, humid air right at the level of the pavement, which is precisely the type of condition that prolongs the drying time even if the temperature seems normal on paper.
ADA Accessible Carport Spaces Need Extra Attention to Vertical Clearance
An accessible space within a carport meets the same width and access-aisle requirements as any other accessible space, but the structure introduces a challenge open-lot accessible spaces don’t have to contend with: vertical clearance. When it comes to a van-accessible space, a vertical clearance of at least 98 inches is required along the route of the vehicle, at the space itself, and along the path leading to the site exit, and an older carport with a lower roofline may fail to meet that clearance without anyone realizing it until a resident tries to use their accessible van. Vertical clearance is measured at the accessible space, not merely at the highest point of the carport, since roof beams and support structures sometimes drop lower over the parking surface than at the outer edge of the carport.
Solar Carports Are Becoming More Common Across Carolina Multifamily
Increasingly, apartment complexes in Carolina are installing solar canopy carports—structures that provide covered parking and also have solar panels on the roof that supply power to the property’s electrical system or offer dedicated electric vehicle chargers below. Unlike ordinary aluminum or steel carports, these solar carports generally have different post spacing and greater clearance height, with the design based on the engineering requirements of the panel array rather than simply the need to cover vehicles. Whenever we draw stripes underneath a solar carport, we go directly by the installer’s structural drawings rather than estimate the position of the posts by eye, since the footings for solar carports are engineered to a particular load and placement specification and should not be treated in the same way as the post spacing of an older style carport, which sometimes can be considered a flexible reference point.
Our Process for Striping an Apartment Carport
- Instead of assuming the distance between posts is the same throughout the carport, measure the actual distance between posts in each bay.
- Check with the local fire marshal about fire lane and fire separation requirements, as standard carports are generally not covered by NFPA 88A and instead follow general fire access regulations.
- When considering any bay that must be accessible to people with disabilities or vans, check the vertical clearance.
- Draw the entire layout, center each area within its bay, and note the post positions so the property manager can approve it before painting.
- Check the assigned space numbers against the property’s current resident roster, as it is not the right time to carry forward an outdated numbering scheme.
- Paint when humidity is moderate, since the cure-time plan needed in a shaded, still-air carport environment is more conservative than that required in an open area.
- The reflective-marked post bases are included as part of the same project, since a freshly striped carport with unmarked posts still creates a real gap in night visibility.
Ready to Stripe or Restripe Your Property’s Carports?
If the carports have never had their stripes repainted since they were constructed or if the numbers assigned to them do not now match the current list of residents, we will measure the actual distance between the posts, verify that the fire access and clearance requirements have been met with your local fire marshal, and provide you with a clean and properly numbered layout. ProLine Parking Lot Maintenance provides services for property managers and owners of multifamily properties across North Carolina and South Carolina, whether for individual property HOAs or large regional apartment complexes.

Keep Apartment Carports Clearly Marked
Faded or poorly positioned markings can make apartment carports harder to navigate and manage. ProLine Parking Lot Maintenance can help property managers maintain clear parking spaces, drive lanes, and traffic markings around carport areas.
Plan Your Carport Striping ProjectFrequently Asked Questions
Do carport support posts themselves ever need to be repainted or marked for visibility, separate from the pavement striping?
Yes, and this aspect is more frequently neglected than the pavement striping. Since support posts are frequently hit by car doors, mirrors, and sometimes by a bump from a bumper, the paint is chipped, and the underlying metal is exposed, leading to rusting over time in the humid conditions of Carolina; it is advisable to check and repair the paint on the posts on about the same schedule as the pavement striping rather than treating it as a separate and less important task. In terms of visibility, a post with high-contrast paint or one that has a reflective strip close to the base is considerably easier for a resident to see when driving in at night than a post that remains in its faded factory-grey or bare primer condition, particularly in a carport bay where the roof already reduces the amount of ambient light.
If a carport’s post spacing doesn’t match a standard vehicle width, can the property widen the spaces without moving the posts?
Yes, in most cases, up to a certain point. The posts being set in concrete foundations means that we cannot move them without carrying out a structural project that goes well beyond the scope of simple painting; however, we can alter the way the paint lines fall within each individual bay so as to make use of the widest possible space that the existing post spacing permits, with the possible consequence of having to give up a space somewhere else in the row if the figures don’t work out evenly. In instances where the original post spacing of a carport is so tight that even a full-width reassignment will still not allow today’s larger SUVs and trucks to be comfortably accommodated, the issue becomes one of the original design limitations of the structure rather than something that can entirely be resolved by painting alone, and we will honestly tell a property manager if this is the case rather than misleading them about what painting can achieve.
Is numbering carport spaces required by any building or fire code, or is it purely a property management decision?
In the Carolinas, fire or building codes do not require numbering carport spaces; instead, property managers have adopted this practice because assigning parking helps reduce disagreements among residents and gives leasing staff a simple way to track which unit has which covered space. Nevertheless, if a property does decide to assign and number the spaces, then the numbers must remain clear and accurate, as a resident, a leasing agent, or even a towing company that has to rely on faded or out-of-date stencilling to verify the vehicle’s assigned spot could end up in a dispute that would have been completely avoided if the numbers had been clear and up-to-date.
Does a solar carport need different striping equipment or a different paint type compared to a standard aluminum or steel carport?
The paint and striping equipment needn’t change depending on the carport type, since in both cases we’re still marking the same asphalt or concrete surface underneath. The thing that does change, however, is the planning that has to be carried out in advance, because the footings and post positions for a solar carport are determined by the solar installer’s engineered drawings, and so the assumptions we normally make regarding post spacing for a conventional carport don’t apply in this situation. We also take greater care when it comes to conduit or electrical cables that may be embedded in or running along the pavement surface in the area of a solar carport’s footings, since any striping work should not involve grinding or other aggressive surface preparation near a cable without first confirming the exact location of that cable.
How often does carport striping need to be redone compared with striping on an open, uncovered part of the same premises?
Carport striping tends to last longer than open lot striping since it is protected from the direct UV rays and rain, which are the main factors in breaking down paint, meaning that a carport area may need repainting after 3 to 5 years rather than 1 to 2 years even if the level of traffic is similar. The only exception is the stenciled numbers, which wear out more quickly in the middle of a designated space than the boundary lines do, simply because the same vehicle parks in that exact spot every day and so concentrates tire wear and oil drips within one fixed area rather than having them distributed across a variety of vehicles as happens in an open, unassigned lot.
Can wheel stops be installed in a carport, or do the support posts make that impractical?
Wheel stops can still work in a carport, but placement needs more thought than in an open lot because a post often sits close to the front of the space. We generally recommend positioning a wheel stop far enough back that a vehicle pulling in fully doesn’t end up with its front bumper closer to a support post than intended, since a driver focused on stopping at the wheel stop isn’t necessarily also judging clearance to a post they may not see clearly in a shaded bay. On some tightly spaced older carports, we recommend skipping wheel stops altogether in favor of a painted stop line instead, since a physical wheel stop in a very tight bay can end up creating more of a tripping or clearance hazard than the parking guidance it’s meant to provide.
If a resident’s assigned space needs to be reassigned or renumbered, is restriping the only way to update it, or are there other options?
Restriping the specific stenciled number is usually the right fix when a reassignment is permanent, since leaving an outdated number in place creates confusion for the resident, other staff, and any towing vendor the property uses. For a temporary or frequently changing assignment situation, some properties use a removable numbered placard or hanging sign mounted near the space instead of repainting the pavement every time an assignment shifts, which costs less and updates faster, though it’s generally viewed as a less permanent, less professional-looking solution than a properly stenciled space. We can restripe just the specific numbered stalls that changed without touching the rest of the carport’s markings, which keeps the cost and scope limited to exactly what needs updating.
