Wales Deck Requirements: Permit Hour, Footings, Guards
In the Village of Wales a deck permit is reviewed at a single Wednesday office hour, so the footings, the septic layout and the fee schedule all get settled on paper before anyone touches a shovel.
Footings
Below frost, past septic
Deck footings still go below the Wisconsin frost line, and on a Wales lot they are also laid out clear of the septic tank and drainfield.
Guards
Above 24 inches
Any deck surface more than 24 inches above grade needs a guard under Wisconsin’s building code, at least 36 inches high with closely spaced balusters.
Permit
$40, filed for you
The Village of Wales charges a flat forty dollar fee for a new deck permit, and T And J prepares and files it for you.
Deck work, start to finish
T And J Deck Construction in Wales
Every deck starts the same way whatever the yard looks like: footings dug below frost and clear of the septic system, posts and beams set, a ledger bolted and flashed at the house, then joists, decking, railings and stairs, all under one fixed price from the same crew.
New build
Custom deck builds
Attached or freestanding, each deck is planned to the door height, the slope of a wooded Wales lot and where the septic tank and drainfield sit, from a small grilling platform to a full outdoor room. The ledger is through-bolted behind flashing so water never reaches the house framing.

Second story
Walkout and upper-level decks
Wales has plenty of split-entry and raised-ranch houses from the 1970s where the lower level walks out to the yard, so the deck off the main floor sits a full storey up on braced posts, with a guard on every open side above 24 inches.

Access
Stairs and step lighting
Stairs are built with even risers, a continuous graspable handrail and a landing wherever the run is long, and on a sloping Wales lot that often means more risers than the plan first shows. Step and post-cap lights are wired in during framing.

Replacement
Deck replacement and resurfacing
When the frame is sound, fresh boards and railings simply go over it. When footings sit too shallow, the ledger has rotted, or the septic lines were never mapped before the last deck went in, the structure comes off and gets rebuilt properly instead of resurfaced over a hidden problem.

What it costs
What a Wales Deck Costs, By Height and Size
Deck cost in Wales follows the same drivers as anywhere in the county: size, height, decking material, railing style and how many stairs it takes to reach the yard. Height decides the most, since anything over 24 inches needs guards, usually stairs, and footings still clear of the septic line below frost.

Decking materials
Choosing Decking for a Shaded Wales Yard
Decking and railing set the upkeep for the life of the deck. The frame beneath is pressure-treated lumber either way; the real choice is the board you walk on and the railing you see through, especially under Wales tree cover.
Pressure-Treated Pine
Affordable boards ready for stain or paint.
Cedar
Rich grain and warmth that needs regular sealing.
Capped Composite
Wood-look boards that skip the staining.
PVC Decking
Light, moisture-proof boards suited to shaded Wales lots.
Wood Balusters
Traditional railing to pair with a stained deck.
Aluminum Railing
Powder-coated metal that never needs repainting.
Cable Railing
Slim stainless cables that keep the tree line in view.
Hidden Fasteners
Hidden clips that keep the surface screw-free.

Wooded, sloping lots
Deck Styles for Wooded Wales Lots
About a third of the homes in the Village of Wales went up during the 1970s building boom, many as split entries and raised ranches on sloping, wooded Kettle Moraine lots with a walkout lower level. Grade at the back of the house, and where the septic system sits, decide more about a Wales deck than square footage does.
Walkout Lot Deck
Common behind the split entries and raised ranches built through the 1970s, where the lower level opens straight to the yard. Because the deck stands a full level above grade, guards, stairs and a properly flashed ledger carry most of the design.
Ranch-Level Deck
On the village’s older ranch homes the door sits close to grade, so the deck stays low, often under the 24 inch guard threshold, and reads as part of the lawn.
Rear Dining Deck
Right off the kitchen door on a flatter village lot, sized to fit a table with enough room to pull out the chairs.
Multi-Level Deck
Two connected levels that step down a sloped Kettle Moraine yard, usually a dining deck above and a lounge below.
Freestanding Deck
Set away from the house where the septic tank, the drainfield or the grade makes a ledger attachment impractical. With no ledger, the frame stands on its own.
Wales permits, village or town
Which Office Signs Off on a Wales Deck Permit?
Yes. Inside the Village of Wales, the Building Inspector reviews deck permits at a single office hour, Wednesdays from 11 am to noon, and charges a flat forty dollar fee. A property outside the village boundary permits instead through the Town of Genesee.
Wisconsin sets no statewide exception for small or low decks, so Wales expects a permit on nearly every new build. Footings must reach undisturbed soil beneath frost, never less than 48 inches under finished grade, whichever runs deeper, and on a village lot they also stay clear of the septic tank and drainfield. Once a deck climbs past 24 inches above grade, guards standing at least 36 inches are required, with balusters spaced no wider than four and three-eighths inches apart, and a stairway of more than three steps calls for a graspable rail. Break ground before the permit is issued and the village doubles what you owe.

Deck FAQ
Wales Deck Permit Questions
Ask about your Wales yard at (262) 352-9525.
What's a typical Wales deck budget?
Deck cost in Wales follows size, height, decking material, railing style and how many stairs the yard requires, plus the village’s flat forty dollar permit fee. T And J measures the site and quotes one fixed figure before work starts.
Which office approves a new Wales deck?
Yes. Inside the Village of Wales a deck needs a building permit reviewed at the Wednesday office hour; outside the village line, the Town of Genesee issues it instead. T And J files either one.
What's the required footing depth here?
Below the Wisconsin frost line, commonly 48 inches under finished grade, and clear of any septic tank or drainfield on the lot. The village confirms the exact depth at review.
At what height do guards become mandatory?
Wisconsin’s building code calls for a guard on any open side of a deck surface more than 24 inches above grade, at least 36 inches tall, with a handrail on longer stair runs.
Does composite pay off under our tree cover?
Composite and PVC cost more upfront than pressure-treated lumber, yet skip the recurring stain-and-seal cycle altogether, which counts for more under Wales’s shade-heavy tree cover where boards dry out slowly. Pressure-treated lumber still makes sense when the budget is tight or finishing the deck yourself is part of the plan.
Does Wisconsin winter stop construction here?
Digging footings and pouring concrete gets far harder once a wooded Wales lot freezes solid, so crews build from thaw through late fall instead. Design work and the Wednesday permit review both happen through the winter months, so the crew can break ground the moment the frost lets go.
Can an old Wales deck skip a full rebuild?
Sound footings, posts, beams and a solid ledger mean fresh decking and railings can be layered straight over what is already there. T And J opens the structure up to check first; rot at the ledger, or footings that never reached proper depth, means a full rebuild rather than a resurface.
What upkeep does a new Wales deck need?
Give the boards a rinse once the snow clears each year, do not let fall leaves pile against them through a wooded Wales lot’s drop, and walk every railing and stair tread each season. Wood surfaces still want restaining every few years to hold up.
