Double Carport vs Single: Which is Right for Holly Hill SC?
By Dubya Carports | October 18, 2026 | 8 min read
For most Holly Hill, SC homeowners, a double carport is the better long-term investment if you have two or more vehicles, need extra storage space, or plan to stay in your home for several years, while a single carport works well for budget-conscious buyers with only one vehicle to protect.
What's the Difference Between a Single and Double Carport?
A single carport typically measures 12 feet wide and provides covered parking for one vehicle, while a double carport spans 18-24 feet wide and accommodates two vehicles side-by-side. The structural difference goes beyond just width—double carports require additional support posts and stronger framing to span the wider distance, which is why authorized dealers like Dubya Carports use heavy-gauge 2x2 square tube construction for their Eagle Carports metal structures. In Holly Hill's climate, where summer thunderstorms and occasional winter weather can take a toll on vehicles, both options provide valuable protection, but the choice depends on your specific needs and property layout.
How Much Does a Single vs Double Carport Cost in Orangeburg County?
Single carports in the Holly Hill area typically start around $1,200-$2,000 for a basic 12x20 structure, while double carports range from $2,500-$4,500 for an 18x20 or 20x20 size. While a double carport costs more upfront, it's important to consider the per-vehicle cost—you're getting nearly twice the coverage for roughly 50-75% more money, making it the better value if you need space for two vehicles. As an authorized Eagle Carports dealer, Dubya Carports offers heavy-gauge metal carports that provide superior durability compared to lighter-gauge alternatives, which matters when protecting your investment through South Carolina's humid summers and unpredictable weather patterns.

When Does a Single Carport Make More Sense for Holly Hill Homeowners?
A single carport is the right choice when you only own one vehicle, have limited yard space, or are working with a tight budget. Many Holly Hill residents with smaller lots near downtown or in established neighborhoods find that a single carport fits perfectly alongside their home without overwhelming their property. Single carports also work well as dedicated spaces for boats, RVs, or tractors—something particularly common in Orangeburg County's more rural areas. Additionally, if you're renting your property or don't plan to stay long-term, the lower initial investment of a single carport makes financial sense since you won't recoup the added value of a larger structure.
Why Choose a Double Carport for Your Holly Hill Property?
A double carport is ideal for households with two or more vehicles, which describes most families in the Holly Hill area. Beyond parking two cars, double carports offer versatile space—you can park one vehicle and use the remaining area for lawn equipment storage, a workshop space, or protection for your motorcycle or golf cart. The extra width also provides more comfortable entry and exit space, so you're not squeezing between posts and vehicles with shopping bags or equipment. Property value is another consideration: homes in Orangeburg County with double carports typically attract more buyers since two-vehicle households are the norm, making it a smart investment if you plan to sell within the next 5-10 years.
What About Weather Protection and Durability in South Carolina?
Both single and double carports protect your vehicles from Holly Hill's intense summer sun, which can fade paint and crack dashboards, as well as rain, pine sap, and tree debris that plague uncovered vehicles. The durability difference comes down to construction quality rather than size—Dubya Carports' Eagle Carports structures use heavy-gauge 2x2 square tube framing that stands up to South Carolina's weather better than lighter residential-grade carports available from big-box stores. For homeowners who prefer a more traditional aesthetic, Dubya Carports also offers pine pole barn construction, which blends beautifully with Holly Hill's rural character while providing the same weather protection. Double carports do have a slight advantage in wind resistance when properly anchored, as the wider footprint creates more stability, though both sizes perform well when installed correctly on Orangeburg County's typically firm soil.
How to Decide Which Carport Size Fits Your Holly Hill Home
Start by evaluating your current and future vehicle needs—if you own two cars now or plan to purchase a second vehicle within the next few years, a double carport prevents the need for a costly second installation later. Measure your available space, keeping in mind that you'll need clearance around the structure for drainage and access. Consider how you use your outdoor space: many Holly Hill homeowners discover they need storage for more than just vehicles once they start planning their carport. Think about lawn mowers, fishing equipment, seasonal decorations, and workshop space. Finally, factor in your budget not just for the initial purchase but for long-term value—a double carport's versatility and resale appeal often justify the additional upfront cost for homeowners planning to stay in their Holly Hill property for more than a few years.
Frequently Asked Questions
Can I add onto a single carport later to make it a double carport?
While technically possible, expanding a single carport to a double is generally not cost-effective and may compromise structural integrity. It's almost always better to invest in a double carport initially if you think you might need the extra space, as building new is more economical than retrofitting and ensures proper engineering throughout the structure.
How wide should a double carport be for two full-size trucks in Holly Hill?
For two full-size pickup trucks, a 22-24 foot wide double carport is recommended to allow comfortable door opening and movement between vehicles. Standard 18-20 foot double carports work fine for sedans and crossovers, but trucks and larger SUVs benefit from the extra width that prevents door dings and makes loading cargo much easier.
Do I need a building permit for a carport in Holly Hill, SC?
Permit requirements in Holly Hill and Orangeburg County vary based on structure size and whether it's permanently anchored. It's best to check with the Holly Hill Building Department before installation, though many portable carport structures under certain size thresholds may not require permits. Reputable dealers like Dubya Carports can guide you through local permitting requirements.
How long does it take to install a single versus double carport?
A single carport typically takes 4-8 hours to install on a prepared site, while a double carport usually requires 6-12 hours depending on customization and ground conditions. Weather and site preparation—including leveling the ground and ensuring proper drainage—can add time to either installation. Most Holly Hill installations are completed in a single day.
Are metal carports better than pole barn carports in Holly Hill's climate?
Both metal carports and traditional pine pole barns perform well in Holly Hill's climate when properly constructed. Metal carports with heavy-gauge framing offer low maintenance and excellent longevity, while pole barns provide a more traditional aesthetic that some homeowners prefer. The choice often comes down to personal preference and how the structure fits with your property's existing appearance.
