Guide · Southeast Wisconsin
Nine governments. Nine ways to price the same remodel.
The same addition is priced by valuation bracket in one municipality, by the square foot in the next, and as a percentage of construction cost in a third. Here is each one, read from its own published schedule.
Start here
“Waukesha” is three governments.
There is a City of Waukesha, a Village of Waukesha and a Town of Waukesha. They are separate municipalities with separate fee schedules and separate permit offices. Pewaukee is both a city and a village. Brookfield, Delafield, Eagle, Merton, Mukwonago and Oconomowoc are each a city or village and a town.
This is not pedantry. A fee quoted from the wrong one is simply the wrong number, and the gap can be large: the City of Brookfield charges by the square foot while the Town of Brookfield charges per thousand dollars of valuation. Those are not slightly different prices. They are different methods of calculation that happen to share a name.
So the first question on any Southeast Wisconsin project is not what the permit costs. It is which of these nine authorities the parcel actually sits in — and the answer is on the tax bill, not the mailing address.
Before you rely on this
A mailing address can carry a city name while the parcel sits in the surrounding town. Utility bills and school district are not reliable either. The assessor’s record is.
The comparison
How each one prices a remodel.
Read from each municipality's own published schedule. Figures are current as of October 2026 and every one is registered with its source and review date.
| Authority | Addition | Remodel / alteration | Minimum |
|---|---|---|---|
| City of Milwaukee | $0.55 / sq ft | 1.6% of construction cost | $200 / $150 |
| City of Pewaukee | $275 base + $0.45 / sq ft | $150 base + $11 per $1,000 of project cost | $150 |
| City of West Allis | $0.45 / sq ft | $0.40 / sq ft | $85 |
| City of Waukesha | $0.41 / sq ft + $145 plan exam | $145 plan exam | — |
| Village of Elm Grove | $0.41 / sq ft | $14 per $1,000 of added valuation | $110 |
| Village of Menomonee Falls | $0.35 / sq ft (see below) | same basis | $65 |
| City of Wauwatosa | Plan review $50–$500, plus an inspection fee charged per unit, per $1,000 of value or per square foot depending on permit type | — | |
Per-square-foot rates run from $0.35 to $0.55 — and three of these authorities do not use square footage for remodels at all. A Milwaukee remodel permit grows with the size of the job because it is a percentage of construction cost. A Menomonee Falls one does not, because it is tied to area. The same $90,000 kitchen produces very different permit figures depending on nothing but the parcel.
Before you rely on this
The City of Brookfield and the City of New Berlin are deliberately absent from this table. Figures for both circulate online, but neither has been read from the municipality’s own current schedule, and after finding four wrong numbers elsewhere that is not a good enough standard to publish against. Call their inspection departments directly.
Often overlooked
Some work needs no permit — but not the same work everywhere.
The City of Waukesha requires no permit to re-roof or re-side a one- or two-family house with no structural changes, or to replace a window or door without changing the size of the existing opening. The same work on a multi-family or commercial building there is charged by valuation.
Wauwatosa exempts re-roofing and residing too — but only where the work does not change the building’s architectural style. That is an aesthetic test rather than a structural one, and it is the narrower of the two. A change of material or profile can pull the job back into permit territory in Wauwatosa when the identical job a few miles west would need nothing.
Milwaukee takes a third approach: repairs that do not involve a structural part, room arrangement, fenestration, exits, stairways, electrical work, plumbing, equipment or fire protection may be made without a permit, provided they do not conflict with the code.
Pewaukee runs the other way. Its fee schedule names kitchens — including cabinet refacing and countertop-only work — as remodels that require a permit. That surprises most homeowners, and it is the sort of thing that turns a weekend project into a correction notice.
The schedule question
Whether you can pour before drawings are approved.
This is the difference that costs weeks rather than dollars, and almost nobody checks it before designing.
City of Pewaukee
Issues an Early Start permit at $150. Footings and foundation can go in while the remainder of the review continues — which in practice can mean getting a foundation in before the ground freezes rather than after it thaws.
City of Waukesha
Offers early start for commercial and multi-family work at $305 and expressly does not allow it for one- and two-family houses. The foundation waits for the full permit, whatever the forecast is doing.
These are adjacent municipalities with opposite policies on the same question. In a climate where footings must reach 48 inches and the building season is already compressed, that single difference can move a project across a winter. It belongs in the conversation at design, not at permit submission.
Three more traps
Rules that are easy to miss and expensive to discover.
Menomonee Falls
Your basement counts.
The $0.35 per square foot is calculated on total living area plus total basement area plus total garage area. Unfinished space you were not planning to think about still enters the fee — which matters most on exactly the kind of lower-level project that is common here and rare in warm-climate markets without basements.
Elm Grove
A board meets before the inspector acts.
Elm Grove runs a Building Board, and its review comes before a permit is issued. No other authority in these two counties adds that step. The fee is only $50; the cost is a place in a meeting calendar, and it belongs in the schedule from the first conversation.
West Allis
Starting early costs triple.
Work begun before the permit is issued is charged at triple the normal permit fee — the steepest penalty found in this market. Elm Grove doubles its fee for the same offence. Neither is a fine you can argue down afterwards.
What to do with this
Three questions, in order.
- Which authority is the parcel in? Check the assessor’s record rather than the mailing address. If the answer is a town rather than the city or village of the same name, every figure changes.
- Does this work need a permit there at all? The exemptions differ, and the Wauwatosa architectural-style test in particular is narrower than it first reads.
- Can the foundation start early? Ask before design is finished, not at submission. In a 48-inch frost market the answer can decide which season you build in.
None of this is the expensive part of a remodel. It is the part that reorders the calendar, and the part a homeowner is least likely to have been told about before drawings exist.
The frost-depth requirement behind that third question is statewide and is set by Wisconsin’s Uniform Dwelling Code, not by any of these nine authorities — footings go below the frost penetration level or at least 48 inches below adjacent grade, whichever is deeper.
