You’ve been dreaming about this day for years. The venue is your own backyard, a family estate, or a sprawling property with views that no hotel ballroom could ever compete with. You’ve got a vision — and honestly, it’s stunning.
But somewhere between “we’re doing this outdoors” and the actual wedding day, a long list of things nobody warned you about will start showing up. Outdoor wedding planning mistakes don’t announce themselves in advance. They show up in your inbox two weeks before the event, or worse — on the day itself.
After 15+ years setting up tents and rentals for Maryland couples, we’ve seen it all. This guide covers the 9 things that consistently catch people off guard — so you can be the couple who planned ahead.
- Your Tent Size Is Probably Wrong
- You May Need a Permit
- Booking Too Late Is the #1 Mistake
- Deposits Are Non-Refundable — Even for Rain
- The Ground Under Your Tent Matters More Than You Think
- Underground Utilities Need to Be Marked
- A “Weather Plan” Is Not the Same as Weather Protection
- No Open Flames Under the Tent — Ever
- A Quote Does Not Reserve Your Date
1. Your Tent Size Is Probably Wrong
This is the single most common outdoor wedding planning mistake we see, and it happens to well-organized couples who did research. They read a general sizing guide somewhere online, came up with a number, and built their entire layout around it — only to realize weeks before the wedding that they didn’t account for the bar, the buffet, the DJ, the dance floor, or the extra clearance required around the tent perimeter.
Here’s the math that matters: round tables require approximately 12 square feet per guest, while rectangle tables need about 10 square feet per person. But that’s just the seating. Add 100 square feet for a DJ setup, 100–150 square feet per buffet line, another 100 square feet per bar area, and then the 5–10 feet of clearance we need around the entire perimeter for staking or weights. A 150-guest wedding isn’t just a 40×60 tent — it’s a 40×60 tent plus your bar, your buffet, your dance floor, and every other element guests interact with.
We offer free site visits. Use them. Having one of our team members walk your property before you commit to a tent size will save you from a very expensive last-minute upgrade.
2. You May Need a Permit — and It’s Your Responsibility
Most couples are surprised to learn that putting up a large tent on a private property in Maryland may require a permit. The rules vary by county and by tent size, but in general: the larger the tent, the more likely a permit is required.
We can guide you on what your county typically requires, but the permit is the client’s responsibility to obtain. This isn’t something you want to discover the week of your wedding. Baltimore County, Montgomery County, Howard County, and others each have their own thresholds and timelines. Some permits require inspection before the tent can be occupied.
Start asking about this the moment you book your tent — not after. If you’re hosting in a park or on public property, you’ll also need the park’s written permission before we can deliver.
3. Booking Too Late Is the #1 Outdoor Wedding Planning Mistake
Maryland has two peak wedding seasons: late spring (May–June) and early fall (September–October). During those windows, popular dates book out months in advance — and we’re not just talking about our tents. Your caterer, your photographer, your florist, and your rental company are all competing for the same Saturdays.
We do accommodate last-minute bookings when inventory is available, but your selection will be limited and availability isn’t guaranteed. If you have a date in mind, book as early as possible. All it takes to hold your date is signing our rental agreement, paying your non-refundable deposit, and keeping a valid credit card on file.
A quote from us is just a proposal — it holds nothing. The date is not yours until the deposit clears.
4. Deposits Are Non-Refundable — Even If It Rains
This is the one that stings. Rain on a wedding day is heartbreaking. But standard cancellation policies apply, and deposits are non-refundable regardless of weather. We do not offer refunds because it rained.
What we do offer is the equipment that makes rain a non-issue. Our tents are commercial-grade vinyl and water-resistant. Solid white walls, windowed walls, or clear walls can be added to fully enclose the tent if needed. If you want the option to add walls later because rain appears in the forecast, call us as early as possible — wall availability isn’t always guaranteed close to your event date.
One exception worth knowing: if an executive order forces cancellation (our “Pandemic Promise”), we offer a reschedule option or a refund. But ordinary weather does not qualify.
5. The Ground Under Your Tent Matters More Than You Think
Not every tent works on every surface — and many couples don’t realize this until we show up for the site visit. Pole tents, which are beautiful and dramatic, must be staked into grass or dirt. They cannot go on concrete, asphalt, or driveways. Frame tents, on the other hand, use weights and can be installed on hard surfaces like driveways and patios.
If your property has a sloped lawn, a deck you were hoping to tent over, or a paved area that seemed like the obvious tent location — let’s talk before you commit. We’ve successfully installed tents on decks (when the structure can handle anchoring), driveways, patios, and even over pools as a specialized request. But we need to assess it first.
The type of ground also affects flooring. If you want a fully floored tent for dancing or to protect heels from sinking into grass, that’s a separate rental item. Our dance floor works on grass, asphalt, or indoors — but flooring the entire tent requires planning the layout in advance.
6. Underground Utilities Need to Be Marked Before We Arrive
This one surprises almost everyone. If you’re installing a pole tent, Maryland law requires that underground utilities be marked before any staking happens. You’ll need to call Miss Utility (dial 811) to have your lines located and flagged. This is the client’s responsibility, and it needs to happen a few business days before your delivery date — not the morning of.
Forgetting this step can delay your installation or, in the worst case, require us to relocate the tent entirely. Neither of those outcomes is good the day before a wedding. Add it to your planning checklist the moment you confirm your tent type and location.
7. A “Weather Plan” Is Not the Same as Weather Protection
Saying “we’ll move inside if it rains” sounds fine — until you realize your backup space holds 60 people and your guest list is 130. A real weather plan for an outdoor wedding means building weather protection into your rental order from the beginning, not treating it as an afterthought.
That means: tent walls if rain is possible. Propane heaters if your date is in October (or even a cool September evening — Maryland nights drop fast). Tent fans or a cooling unit if you’re hosting in July or August under a fully enclosed tent. Our vinyl block-out fabric keeps things significantly cooler than direct sun, but it doesn’t replace airflow for summer events.
We also need to flag wind: our policy requires evacuating the tent if winds exceed 38 mph, and if there’s lightning, everyone needs to leave immediately. These aren’t arbitrary rules — they’re safety requirements. Build an indoor backup area (even just a large covered porch or garage) for guest shelter if severe weather develops.
8. No Open Flames Under the Tent — Ever
This is non-negotiable. No cooking under the tent, no bonfires near the tent, no open flames of any kind. If you’re planning to have a caterer use open flame equipment, they need to be positioned outside the tent. Bonfires or fire pits require at least 50 feet of clearance from the tent structure. Candles are a gray area — ask us about your specific setup.
This isn’t about being overly cautious. Commercial vinyl tent fabric is not fireproof, and smoke or ash can permanently damage it in addition to the obvious safety risk. If your caterer plans to use any heat source, confirm with us before your event. We can help plan the layout so cooking stations work safely outside the tent footprint.
One more note: our heaters — which are propane-powered — sit outside the tent. The heating unit and propane tank are always exterior, with a vent blowing warm air into the interior. That’s how they’re designed to work safely.
9. A Quote Does Not Reserve Your Date
We save this one for last because it’s the one people find out about the hard way. You request a quote. We send a beautiful itemized proposal. You tell your family, you share it with your planner, you start mentally committing to the date. And then, two weeks later, you come back to book — and the tent you wanted is no longer available for that date.
A quote is a proposal. It holds nothing. Your date is not reserved until you’ve signed the rental agreement, paid your non-refundable deposit (typically 50% of the order total), and have a valid credit card on file. The moment those three things are in place, your date is locked.
This applies to inventory changes too: you can add items at any time if they’re still available, but if you reduce your tent size after booking, you may still be liable for the original reservation. Talk to your event specialist before making changes.

How far in advance should I book a tent for my outdoor wedding in Maryland?
As early as possible — especially for spring and fall dates, which are peak season. Popular Saturdays in May, June, September, and October can book out months in advance. Once you have a date in mind, getting your deposit in is the only way to hold inventory.
Are DER tents waterproof?
Yes. Our tents use commercial-grade vinyl that is water-resistant. For full protection in rain, you’ll want to add tent walls. We carry solid white, windowed, and clear walls — ask about availability when you book so they’re reserved with your tent.
Do I need a permit to put up a tent in my backyard in Maryland?
It depends on your county and the tent size. Many counties require permits for large event tents. We can help guide you on what to expect in your area, but the permit application and approval is your responsibility. Start this process early — some counties require inspections before the tent can be occupied.
What happens if I need to cancel my outdoor wedding rental?
Our deposit is non-refundable. Standard cancellation policies apply, and rain alone does not qualify for a refund. If you need to cancel, contact us as soon as possible — depending on timing, you may not owe the full balance. Our “Pandemic Promise” provides a reschedule or refund option if a government executive order forces cancellation.
