Delaware Beach Laws:
What’s Actually Legal
at Rehoboth in 2026.
“The rules at Rehoboth Beach are real, actively enforced, and not always obvious. Alcohol, dogs, smoking, fires, umbrellas, bikes on the boardwalk — here’s exactly what’s legal, what isn’t, and what will get you a ticket.”
In this guide
01 — Quick reference
The rules at a glance
before you hit the beach.
Rehoboth Beach enforces its rules. This is not a place where the regulations exist on paper and nobody cares. Undercover officers operate during peak season, fines are real, and the town takes its beach regulations seriously. Here’s the master reference before we go into detail on each category.
02 — Alcohol rules
No open containers.
Anywhere public. Full stop.
This is the rule most visitors get wrong and most citations are written for. Delaware law and Rehoboth Beach ordinance prohibit open containers of alcohol on the beach, on the boardwalk, and on any public street within the city limits. This applies to everyone — any age, any drink, any container.
What this actually means
That cup of wine walking down Rehoboth Avenue to the boardwalk — illegal. The beer in your hand on the beach — illegal. The bottle of seltzer that’s actually vodka — still illegal and officers know the difference. Open container citations are written regularly during peak season and Senior Week enforcement specifically targets this.
Alcohol stays in private spaces: your rental house, a restaurant with a liquor license, a licensed bar or hotel. Nowhere outside.
The drinking age in Delaware is 21 — federally mandated since 1984 and enforced with zero tolerance at Rehoboth. For context: when Senior Week regulars from the early 1980s were going, Maryland’s drinking age was 18 for beer and wine. That world is long gone. Undercover officers operate specifically during Senior Week looking for underage consumption.
What IS legal
Drinking alcohol in your rental house or vacation property — completely fine. Dining and drinking at a licensed restaurant or bar — fine. Bringing a sealed, unopen bottle in your beach bag — fine as long as it stays sealed and out of sight in public spaces.
03 — Dogs on the beach
Summer ban. Off-season welcome.
Know the dates exactly.
Rehoboth Beach has a complete ban on dogs on the beach and boardwalk during the summer season. This is one of the most asked-about rules and one of the most enforced. The dates are firm.
Traveling with a dog? Your best option in summer
Dewey Beach — just south of the Rehoboth boardwalk — allows leashed dogs before 9:30am and after 5:30pm with a Dewey Beach Dog License during summer. It’s a 10-minute drive from most Rehoboth rentals. The early morning beach walk with your dog in Dewey, before the crowds arrive, is genuinely one of the better experiences on the Delaware coast. Cape Henlopen State Park also allows dogs on trails year-round.
04 — Smoking & marijuana
Smoke-free beach.
And yes, that includes marijuana.
Rehoboth Beach is effectively smoke-free. The beach, the boardwalk, dune crossings, the Bandstand plaza, access ways, city parks, and playgrounds are all designated smoke-free areas. Signed designated smoking areas exist at some dune crossings — those are your only legal option for tobacco on or near the beach.
Marijuana — a common misconception in 2026
Delaware legalized recreational marijuana for adults 21+ in 2023. Many visitors assume this means they can smoke or use marijuana freely at the beach. They cannot. Delaware law prohibits marijuana consumption in all public places — including the beach, boardwalk, and any outdoor public space. Smoking marijuana at Rehoboth Beach is illegal and is being actively enforced in 2026. Arrests for public marijuana use were specifically noted during the May 2026 Rehoboth Beach incidents.
Marijuana can be legally consumed in private residences. Not in public. Not on the beach. Not on the boardwalk. Not on a rental property deck that faces a public street.
05 — Beach rules
What you can and can’t
bring to the beach.
Beyond alcohol and dogs, Rehoboth Beach has specific rules about what’s allowed on the sand that catch visitors off guard regularly.
Umbrellas — size matters
Maximum pole height 7 feet 6 inches. Maximum shade diameter 8 feet. The oversized market umbrellas and large beach canopies that are popular elsewhere are not permitted. Standard beach umbrellas are fine.
No tents or canopies
Tents, canopies, cabanas, tarps, sportsbrellas — all prohibited. The only exception is baby tents no larger than 3 feet high, 3 feet long, and 4 feet wide. If you’re bringing a pop-up shade tent, leave it at the rental.
No glass containers
No glass bottles or containers of any kind on the beach. This applies to water bottles, wine bottles, everything. Plastic and aluminum only. Enforcement is real — broken glass on a beach is a serious safety issue and the city takes it seriously.
No fires or grills
Absolutely no fires, bonfires, fire pits, grills, or cooking surfaces of any kind. No exceptions. This includes portable propane grills and charcoal. All cooking stays at your rental property.
No ball games when lifeguards on duty
When lifeguards are present, games involving running or moving objects — balls, frisbees, kites — are prohibited near the guarded swimming area. Move further down the beach away from the guarded zones for active games.
No feeding seagulls
Feeding seagulls is prohibited. This sounds minor until you’ve seen what happens when someone starts feeding them — within minutes you’re surrounded by dozens of aggressive birds. The rule exists for good reason.
06 — Boardwalk rules
The boardwalk has its
own set of rules.
The Rehoboth Beach boardwalk — one mile of wooden planks running north and south from Rehoboth Avenue — has specific regulations separate from the beach rules.
Bikes — before 10am only
Bicycles are permitted on the boardwalk only between 5am and 10am in summer. After 10am it’s pedestrian only. This is strictly enforced. Plan your boardwalk bike ride for early morning — which is honestly the best time to do it anyway.
No roller skating or rollerblading
Roller skating and rollerblading are prohibited on the boardwalk and on Rehoboth Avenue. This applies year-round.
No alcohol
The boardwalk is a public space and the open container prohibition applies fully. No drinking on the boardwalk regardless of age.
No smoking
The boardwalk is a designated smoke-free area. This includes tobacco and marijuana.
No sleeping under the boardwalk
Sleeping under the boardwalk, on benches, or in cars parked on city streets is prohibited. This is enforced year-round.
No changing clothes
Changing clothes in comfort stations, on the boardwalk, under the boardwalk, or in vehicles parked on public streets is prohibited. Use your rental or designated changing areas.
07 — Swimming rules
Lifeguard hours are
the rule, not a suggestion.
Swimming at Rehoboth Beach is permitted only when lifeguards are on duty. After lifeguard hours, swimming is prohibited — not discouraged, prohibited. The beach itself is closed between 1am and 5am.
Why this rule matters
The Atlantic at Rehoboth has real currents, real waves, and real rip tide potential. Night swimming with impaired judgment — after a long evening on the boardwalk or at the bars — is the combination that produces tragedies. This rule is not bureaucratic caution. It is based on what actually happens when people ignore it. Follow it.
Lifeguard hours (approximate — confirm on arrival)
Lifeguards are typically on duty from 10am to 5:30pm daily during the summer season. Hours can vary by date and staffing. Check the flag system on arrival — flags indicate water conditions and whether swimming is permitted in specific areas. A red flag means no swimming. Respect it.
08 — Nearby beaches
How the rules compare
across the Delaware beaches.
If Rehoboth’s rules feel restrictive for your specific situation — traveling with a dog in summer, wanting a beach bonfire, looking for more flexibility — here’s how the nearby Delaware beaches compare.
Dewey Beach — most flexibility
Dogs allowed before 9:30am and after 5:30pm in summer with a Dewey Beach Dog License. Beach open later than Rehoboth. The most relaxed enforcement environment of the Delaware beaches. Still no alcohol on the beach or public spaces.
Bethany Beach — similar to Rehoboth
No dogs May 15–September 30. No alcohol in public. Smaller boardwalk, quieter town, same general regulatory framework as Rehoboth. The “Quiet Resort” takes its rules as seriously as its peace.
Cape Henlopen State Park
Dogs allowed on trails year-round. No dogs on the swimming beach May 1–September 30. State park rules apply — generally well-maintained, well-staffed, and clearly posted. Great alternative for dog owners.
Delaware Seashore State Park
South of Dewey Beach. Dogs allowed in most areas outside the designated swimming beaches. More space, less crowd, same Delaware coastal beauty. Worth knowing about if you want alternatives to the town beaches.

Rehoboth Beach has more regulations than some beach towns and fewer than others. The rules exist for real reasons — safety, shared space, the preservation of a beach that has served generations of families. Understanding them before you arrive means you spend your time in the water and on the boardwalk instead of dealing with citations and avoidable situations.
The short version: no alcohol in public, no dogs in summer, no glass, no fires, no tents, no smoking, swim only when lifeguards are present. Everything else is the beach doing what the beach does — which, at Rehoboth, it has been doing very well for a very long time.
