Permit First, Then the Build: Finishing Lannon Basements
T And J All In Remodeling finishes basements across the Village of Lannon, from masonry lower levels on the old Stone City streets to poured basements in newer homes. Teli and John Karampetsos file every village permit before work starts, schedule the build around the 90 day permit window and fix one written price.

Permit calendar
A Lannon Basement Runs on the Permit Calendar
Lannon prints its deadlines on the permit itself, so a basement here is planned against the calendar as much as the budget. The three figures below come from the village permit forms and from T And J’s own pricing and cost guide.
Permit life
90 days
Every Lannon permit expires 90 days from its date unless the form notes otherwise, and fees are not refunded. T And J files once the build is ready to start.
Build time
6–10 wks
T And J’s cost guide puts an 800 to 1,000 sq ft basement at six to ten weeks from approval to final, which fits the permit window. Fuller build-outs run ten to twelve.
Budget band
$20k–$60k+
An open recreation room starts near $20,000. Plumbing, a bedroom egress cut through older masonry, or a full suite carries the figure to $60,000 and beyond.
Second living room
A Second Living Room Under a Compact Lannon House
Most Lannon houses are modest in size, so the basement is often where a family finds its second living room, guest room or bathroom. Each space below goes in the same order: water checked, walls insulated and framed, systems roughed in and inspected, then finishes, all by one in-house crew.
Whole level
Stone, block or poured walls finished
In a Lannon house the finish starts with what the foundation is made of. Stone and block walls get closed-cell spray foam that follows their uneven face, while poured walls take rigid foam board. Studs stand clear of the concrete, new circuits feed the lighting, and drywall, trim and flooring close the room. The furnace and water meter stay reachable.
Foundation
Spray foam on stone, board on poured
Overhead
Drywall, or lift-out tiles at valves
Slab
Plank, carpet or tile once dry
Gathering space
Room enough for a sectional
In a compact village house the basement is often the only room big enough for a sectional, a big screen or a pool table. Speaker, HDMI and network lines go in before drywall, recessed lights sit on dimmers, the equipment gets its own circuit, and a pool table is placed by measuring cue room first.

Lights

Guest room
Egress cuts in masonry walls
A lower-level bedroom needs an egress window with a clear opening of at least 20 by 24 inches and a well, or a door outside, plus interconnected smoke and CO alarms. In a Lannon masonry foundation the cut is a real piece of work, and a home still on private septic needs a Waukesha County site evaluation first.

Plumbing
Bathrooms and the sewer lateral
Lannon wastewater flows to the treatment plant managed by the Village of Sussex, and the height of your sewer lateral where it leaves the house decides the drain plan. A lateral below the slab means saw-cutting the floor and tying in by gravity; one above it means an ejector pit or up-flush unit. Showers are membraned and the fan ducts outdoors.

Bars where the water lines are
A bar costs least where supply and drain are already close, so its spot is chosen with the plumbing, not the furniture. In houses that switched from a private well to village water, John notes where the new service and meter came in before choosing it. Cabinets, quartz or granite tops and under-cabinet lights follow.

Utility
Utility rooms after the well
Shelving, closets and a clean utility room make the finished rooms easier to live in. Where an older stair is steep or tight overhead, treads, rail and lighting are rebuilt to code. In homes that moved to village water, a retired well tank can free up floor, and the furnace, water heater and panel keep their clearance.

House-driven costs
What Will It Cost to Finish Your Lannon Basement?
Square footage sets the starting figure, and what goes into the space moves it. In Lannon the bigger swings often come from the house itself: a stone or block foundation that needs moisture work, an egress opening cut through masonry, or a bathroom where the sewer lateral sits above the slab. T And J writes one fixed price after the walkthrough.

Stone, block, poured
Insulating Stone, Block and Poured Walls in Lannon
A basement wall here may be laid stone, concrete block or poured concrete, and each one handles damp differently. Materials are picked for how they cope with water and vapor first, then for comfort.
Rigid Foam Insulation
Board that sits flat on poured walls and never absorbs water.
Closed-Cell Spray Foam
Follows the rough face of stone and block and seals rim joists.
Moisture-Resistant Drywall
Used beside showers, bar sinks and the washer.
Drop Ceiling
Panels lift out wherever valves, cleanouts or junctions sit above.
Luxury Vinyl Plank
A waterproof core for family rooms and play space.
Porcelain Tile
Indifferent to water, so it goes in baths and bars.
Carpet and Pad
Soft in guest rooms and theaters, laid only over a dry slab.
Egress Window Wells
Galvanized or composite wells sized for a cut through masonry or concrete.

Quarry village homes
Stone City to Village Edge: Lannon's Houses
Lannon was incorporated in 1930 as a quarry village on the Niagara Escarpment, and its houses record that history. Joseph Hadfield’s 1890 plat produced the worker homes known as Stone City, mid-century ranches and capes filled in later streets, and newer houses sit toward the village edge. Each era hands a basement project a different starting point.
Stone City Homes
Houses from the 1890 Hadfield plat on streets such as Lake, Vine, State and Bay, built for quarry workers. Masonry walls and limited headroom are common, and moisture is checked first.
Postwar Ranches and Capes
Compact mid-century houses. Foundation type varies, so John confirms block or poured, then maps the forced-air trunks and beam that decide where rooms can go.
Split-Levels
The lower level sits partly above grade, so windows are larger and daylight easier, though a crawl space or short basement can sit beside it.
Newer Village-Edge Homes
Recent houses toward the edge of the village generally have taller poured walls, and John checks for any plumbing rough-in the builder left in the slab.
Services Arrived Late
Lannon had no central sewer in 1990, and village water reached more than 170 properties only in 2021. Older basements can still hold retired well equipment or rerouted service lines, so every line is traced before a layout is drawn.
Permit terms
What Does the Village of Lannon Require Before Basement Work Starts?
A permit, issued before anything happens on site. The Village of Lannon uses separate building, electrical, plumbing and HVAC permit forms, and those forms state that triple fees are due when work starts before the permit is issued.
The village appoints its building inspector, and the Village Clerk at the village hall on West Main Street handles permit paperwork. Lannon’s permit forms add a 10 percent administrative fee to every permit, state that a permit expires 90 days from its date unless noted otherwise, and make permits non-refundable and non-transferable. Inspections need at least 24 hours’ notice, and failing to call for one carries its own fee. Some Lannon mailing addresses fall in the Village of Lisbon or Menomonee Falls, which permit separately, and a home on private septic needs a Waukesha County site evaluation before a bedroom is added. T And J confirms the parcel, files every form and books each inspection.

The sequence
How a Lannon Basement Gets Built
Because a Lannon permit lapses 90 days after issue, the schedule is set before filing: layout fixed, windows and fixtures ordered, then the permit, then five build stages with an inspection before each layer is covered. Inspections are requested at least 24 hours ahead as each stage begins.

Permit-first FAQ
Answers for Lannon Homeowners
For your own house, call John at (262) 352-9525.
What does it cost to finish a basement in a Lannon house?
Most Lannon basements T And J finishes fall between about $20,000 for an open recreation room and $60,000 or more for a suite with a bedroom, bathroom and bar. Square footage sets the base. Older stone or block walls that need moisture work, and egress openings cut through masonry, are what push a quote higher here.
What happens if basement work starts before the Lannon permit?
The village’s permit forms state that triple fees are due when work begins before the permit is issued, on top of the 10 percent administrative fee. Work may also have to be opened back up for inspection. T And J files first and starts only once the permit is in hand.
Can a basement finish be done within Lannon's 90 day permit?
Often, with planning. T And J’s cost guide puts an 800 to 1,000 square foot basement at six to ten weeks from permit approval to final inspection, and a fuller build-out at ten to twelve. A bathroom adds two to three weeks, so if a scope could run past 90 days, that is settled before the permit is pulled.
Our house is on the old Stone City streets. Can it be finished?
Often, but only after an honest look. Houses from the 1890 Hadfield plat were built for quarry workers, and their basements can have stone or masonry walls, limited headroom and damp. John checks all three. If the space can be made dry and tall enough, it is finished; if not, he says so.
What happens to our old well equipment?
More than 170 Lannon properties moved to village water through the 2021 water project, after E. coli and fecal coliform turned up in private wells. Some basements still hold an old pressure tank or treatment unit. John checks what is still connected, and retired equipment can usually come out so the floor goes into the plan.
Is radon testing worth it before finishing?
Yes, and before the walls close. Wisconsin’s Department of Health Services puts high radon in roughly one home in ten statewide, with 4 pCi/L as the level where action is advised. Test kits are sold by Waukesha County Environmental Health. If mitigation follows, its pipe is routed through open framing.
How does the sewer connection decide where a basement bathroom can go?
Lannon had no central sewer in 1990; today its wastewater goes to the plant managed by the Village of Sussex. Where your lateral leaves below the slab, new drains tie in by gravity after a saw cut. Where it leaves higher, an ejector pit or up-flush unit lifts waste to it. A house still on septic is checked first.
Does a Lannon mailing address mean the village permits it?
Not always. Some Lannon addresses sit in the Village of Lisbon or the Village of Menomonee Falls, and each issues its own permits on its own terms. T And J checks the parcel before quoting, so the permit, fees and inspector are the right ones from the start.
