An outdoor kitchen contractor on Cape Cod builds a permanent cooking station in the yard: a masonry island on its own base, a stone top, a built in grill, and the gas, power and water that feed it. The grill is the easy part. The hard part is building something that sits in salt air all year, freezes every winter, and still opens, lights and drains in May.
Coast Carpentry Home Group builds outdoor kitchens on Cape Cod as part of our masonry on Cape Cod, from our shop at 14 Parker Rd, Unit A in Osterville. Our crews set the base, lay the block, veneer it in stone or brick and set the top, and we bring in the licensed trades for gas, power and water. This is how we build one, what the town will ask for, and the choices that decide whether it still looks right after ten winters.
Key takeaways
- An outdoor kitchen island on Cape Cod sits on its own reinforced concrete pad over compacted stone, separate from the patio pavers, so the island and the patio can each move a little without cracking the other.
- We build the island core from concrete block. Block does not rust, rot or burn, and within sight of salt water that matters more than any finish you put over it.
- Stainless steel is not one material. Grade 316 resists salt pitting, grade 304 tea stains near the water unless it is rinsed, and the magnetic grades on bargain grills rust first.
- Gas piping in Massachusetts is done by a licensed plumber or gas fitter under a gas permit, and outdoor power by a licensed electrician under an electrical permit. A roof over the kitchen adds a building permit.
- A summer house kitchen has to be drained every fall. We pitch the water line back to a shutoff inside the heated house so winterizing takes minutes, not a plumber’s visit.
What does an outdoor kitchen contractor on Cape Cod actually build?
Most of what you see in a photo of an outdoor kitchen is appliance. Most of what we build is the part nobody looks at again: the pad, the block, the chases for the gas and the wire, the steel over each opening. That hidden work is what separates a kitchen that lasts from one that looks tired by its fourth summer.
We are builders, not an appliance showroom. You choose the grill, the doors and the refrigerator, and we ask for the manufacturer cut sheets before a single block is laid. Every opening, every vent and every clearance comes off those sheets. A grill picked after the island is finished is how people end up grinding stone to make it fit.
The ground comes first. A kitchen is only as flat as what it stands on, which is why we treat paver patio installation on Cape Cod and the kitchen as one plan. Our pool patio project at 32 Old Toll Road, where we rebuilt the grade with a segmental wall before the pavers went down, is the kind of groundwork an island wants around it.
What goes under an outdoor kitchen island in Cape Cod sand?
Clean Cape sand drains fast, and soil that drains does not heave much. The trouble is the layer above it. Loam, old fill and buried stumps hold water, and water is what frost needs to lift things. So the dark soil comes out until we reach clean sand, and compacted stone goes back in its place.
We never set a masonry island on the pavers. Pavers ride on a thin bed of sand and are meant to flex a little through the winter. A block island with a stone top weighs far more than that bed was built to carry, and it cannot flex at all. Give it its own pad, leave a joint between pad and patio, and each can do what it was designed to do.
The sleeves for gas, power and water go into the ground before the concrete does. That is one more reason the appliance list has to be settled early. Cutting a trench through a finished patio to add a line somebody forgot is the most expensive hour on the job.
Why do we build the island from concrete block and not a metal frame kit?
A frame kit goes together fast, and inland, behind a windbreak of pitch pine, a good aluminum one can be a fair choice. We say so when it is. Within sight of the water in Hyannis, Falmouth or along the Sound in Mashpee, we do not build them. Salt haze finds the cut ends, and the board skin lets go of the stone when the frame behind it swells with rust.
Block is also noncombustible, which matters more than people expect. A grill dropped into a wood or light frame cabinet needs an insulated jacket to keep heat off the structure. Set in block with the clearances from the manual, the island itself is the protection.
Over the block goes natural stone or brick. Our guide to stone veneer installation on Cape Cod covers the lath, ties and mortar we use near salt water, and the same rules apply to an island. If you are torn between the two faces, start with our comparison of brick vs stone masonry for this climate.
Which stainless steel survives salt air on Cape Cod?
| Grade | What it is | How it behaves near salt water |
|---|---|---|
| 430, magnetic | The steel on many bargain grills, side panels and doors | Rusts first, at seams and screw heads. We steer owners away from it anywhere on the Cape. |
| 304 | The standard grade on well made grills and access doors | Fine inland. Near the water it tea stains brown unless it is rinsed with fresh water and wiped down. |
| 316, marine grade | Stainless with molybdenum added to resist chlorides | What we ask for within sight of salt water, including hinges, drawer slides and fasteners. |
The word stainless on a box tells you almost nothing. Ask the dealer what grade the body is, what grade the burners are and what the fasteners are made of, because a 304 lid on a 430 cabinet is common. A refrigerator magnet is a fair field test. If it grabs a panel hard, that panel is a lower grade.
Hinges, slides and screws fail before sheet metal does. A door that looks perfect and will not open is how that failure shows up. For doors and drawers near the shore, 316 or a marine polymer cabinet is worth it.
Even the right grade wants a rinse. Salt sits on a surface that rain never reaches, such as the underside of a hood or the inside face of a door. A hose and a soft cloth a few times a season does more than any polish.
What countertop holds up outdoors through a Cape winter?
Color is a comfort question before it is a style question. Black granite in July sun gets too hot to lean on, so we point owners toward lighter grays and a honed or leathered finish, which also hides salt spots better than a polish.
We set the top with a slight pitch so water runs off, and we cut a drip groove under the overhang so that water falls clear and does not run down the stone face. That one groove is the difference between a clean veneer and a streaked one.
Bluestone suits a Cape yard and matches the treads and caps we already set around patios, but it drinks grease, so it needs sealing every spring. Poured concrete tops can look good and usually show hairline cracks within a few winters. We tell people that before they choose one, not after.
Who runs the gas and electric, and which permits does an outdoor kitchen need?
Plenty of Cape streets have no gas main, so many of these kitchens run on propane, either from the house tank or from one the propane company sets for the kitchen. The island gets vent panels either way, placed where the appliance manual says. Gas that leaks into a sealed stone box has nowhere to go, and that is a risk nobody should build.
Power means weather resistant receptacles with ground fault protection and covers that close over a plug, a circuit for the refrigerator, and lighting on its own switch. We plan task light over the grill early, because the cook is the one person who cannot see once the sun drops behind the trees.
Each town has its own counter. The Barnstable Building Division is a good example of what a Cape town asks for. If any part of the work falls within 100 feet of a wetland or the shore, Conservation sees it before anyone digs. On the north side, a pavilion visible from Route 6A also goes to the Old King’s Highway Historic District Committee.
Can an outdoor kitchen have a sink on a septic lot?
Title 5 sizes a septic system by bedrooms, so a sink does not add design flow and does not by itself force an upgrade. The town still decides how the tie in is made, and the drain needs enough pitch to reach the house line. On a long, flat run across a yard that pitch is sometimes just not there.
A sink that drains onto the ground or into a homemade dry well is not legal plumbing, and we will not build one. It is also the first thing to freeze and split.
Before you commit to a sink, look at the drain run on paper. The kitchen sink is a short walk away, and a hose bib at the island for filling pots and washing down the stone gives most of the use for a fraction of the work. That is the trade we lay out for every owner who asks.
Where should the grill go when the wind comes off the water?
South side yards in Yarmouth, Hyannis and Falmouth get the sea breeze off Nantucket Sound most summer afternoons, right at the hour people light the grill. Grill makers warn about wind from behind in their manuals, and scorched knobs are what it looks like when the warning is ignored. Turning the island a quarter turn, or raising the back of it into a low wind wall, solves it for good.
Think about where the smoke goes next. It should not drift into the open kitchen window or through the screens of a porch. Weathered white cedar shingles are dry wood, so the grill never backs up to the house wall and never sits under a low eave.
Then walk the route. The cook carries trays out the kitchen door and back, so a short, level path with no step in the dark is worth more than a view. We like the grill where the cook can still see the table.
Should an outdoor kitchen on Cape Cod be covered or open?
A pavilion is a sail in a nor’easter. Its posts have to be tied down to their piers with stainless or hot dip galvanized hardware, and the roof framed to resist uplift, the same as any addition. A roof also counts toward lot coverage in most Cape towns, which is the number to check before you fall in love with a size.
A pergola is the middle ground. Open rafters give shade without trapping heat and smoke over the grill, though the posts still want real footings.
If what you are after is dinner outside without the greenheads, a roof over the grill is not the answer. An open grill station beside a screened room is the better pair, and our guide to how a screened porch is built on Cape Cod covers that half.
Can you build an outdoor kitchen on a deck?
We look at the framing from below before we answer. Joist size, span, the ledger and the footings tell us what the deck can take, and adding piers under a new island is ordinary work when the plan allows it. That is part of our deck installation on Cape Cod.
Heat and grease are the other half. A grill over wood or composite boards needs a noncombustible surface under and in front of it, sized to the manual, and composite boards scar from a dropped coal faster than people expect. Our guide to composite deck installation on Cape Cod explains what those boards will and will not forgive.
More often than not the better plan puts the island at grade, a few steps down from the deck. The weight sits on the ground where it belongs and the deck stays a place to sit.
How do you winterize an outdoor kitchen at a summer house?
Many Cape houses are closed up by Columbus Day and opened again in May, and nobody is there in January to notice a problem. A water line that freezes inside a stone island splits where you cannot see it and shows itself in spring as a wet patio. So the shutoff goes in the heated basement, with a drain on it, and the line slopes back toward it the whole way.
Shut the gas at the island valve too. Use a cover that breathes. Wrapping a stainless grill in a plastic tarp holds salt and moisture against the metal for five months, which does more harm than leaving it bare.
Keep rock salt and ice melt off the stone and away from the mortar joints. We go into why in our guide to landscape masonry that works with Cape Cod weather. A rinse and a fresh coat of sealer on the top each spring is the only upkeep the masonry asks for.
What does an outdoor kitchen cost on Cape Cod?
The driver people miss is distance. An island tucked against the house with the gas meter around the corner is one job. The same island at the far side of a pool, with a trench across a finished lawn and under a patio, is another. We would rather tell you that standing in the yard than in a change order.
Appliances are your choice and often the largest single line. Stone and top come next. The base and the block, the parts that decide how long it all lasts, are a smaller share than most people guess, which is why we never cut there.
Our masonry carries Coast Carpentry Home Group’s lifetime workmanship warranty, and the appliances carry their makers’ warranties. Tell us what you have in mind on our contact page and we will come look at the yard.
When do we tell a homeowner not to build an outdoor kitchen?
A built in kitchen earns its keep in a house where somebody cooks outside most nights from June into September. For a family that visits four weekends a year it is a stone box to maintain. We would rather lose the job than build something you resent every fall.
We also say no when the ground is not ready. An island on a patio that is already sinking, or at the foot of a slope that sheds water toward it, will follow the patio down. Fix the ground first, sometimes with a retaining wall built for Cape sand and slopes, then build on it.
And we push back on any plan that puts the grill under the eave because that is where the old one stood. If you are still weighing who should build it, our guide on how to choose a masonry contractor on Cape Cod lists the questions worth asking, including the ones we would want you to ask us.

Frequently asked questions
Do I need a permit for an outdoor kitchen on Cape Cod?
Usually more than one. The gas line needs a gas permit pulled by a licensed plumber or gas fitter, and the wiring needs an electrical permit pulled by a licensed electrician. A sink adds a plumbing permit. A roof or pavilion over the kitchen needs a building permit, and work within 100 feet of a wetland or the shore goes to the Conservation Commission first. Coast Carpentry Home Group coordinates the trades and the filings as part of the job.
What is the best material for an outdoor kitchen near the ocean?
Concrete block for the island core, natural stone or brick for the face, sealed granite for the top and grade 316 stainless steel for the grill, doors, hinges and fasteners. Block cannot rust or rot, granite handles freeze and thaw, and 316 stainless resists the salt pitting that stains and seizes lower grades within sight of the water.
Can an outdoor kitchen stay outside all winter on Cape Cod?
Yes, if it is built for it and drained in the fall. The masonry stays where it is. The water line is shut off inside the house and drained, the sink trap is protected, the refrigerator is emptied and unplugged, and the grill is cleaned and covered with a cover that breathes. Keep rock salt and ice melt off the stone and mortar.
Should an outdoor kitchen on Cape Cod use natural gas or propane?
Use natural gas if the street has a main and the house is already connected, because the supply never runs out in the middle of dinner. Many Cape streets have no gas main, so propane from the house tank or a dedicated tank is common and works just as well. The grill has to be ordered for the fuel it will burn, and either way a licensed plumber or gas fitter runs the line under a permit.
Can you add an outdoor kitchen to an existing patio?
Yes, when the patio is sound. We lift the pavers where the island will stand, dig out and pour a reinforced pad for it, run the gas, power and water in sleeves, and relay the pavers up to the new island. If the patio is already sinking or holding water, that gets fixed first, because the island will follow whatever the ground under it does.
