Nashotah Addition Rules: Yards, Open Space, Footing Survey
The village’s main single-family districts call for lots of one acre or half an acre, so floor area is seldom the limit. What the plan has to respect is the district’s yard distances, the share of the lot kept open, and a village step that surveys new footings before any backfill goes in.
Side yards
25 ft in R-1
The one-acre R-1 district keeps a 25-foot side yard on each side; the half-acre R-2 district allows 15 feet.
Open space
70% in R-1
R-1 lots keep at least 70 percent of the lot open and R-2 lots 75 percent, so the new footprint is added into that sum.
Footings
Surveyed on site
A surveyor certifies the footing forms against the permitted setbacks, and backfill waits for the Building Inspector’s confirmation.
Which way to grow
Room and Second-Story Additions on a Wide Nashotah Lot
On a wide village lot the question is usually which way to grow, not whether there is room. Each addition is set out against the district’s yards, poured on footings the village has seen surveyed, tied into the roof and siding of the house, then fitted out by one in-house crew on one fixed price.
Out the back
Room Additions on Deep Back Yards
A family room, main-floor primary suite or bigger kitchen built on new footings, most often off the rear of a 1990s two-storey where the backyard runs deep. The 25-foot rear yard is measured first, and the old exterior wall becomes the opening between rooms at the end.

Modest gain
Small bump-out additions
A few feet taken from the yard on one wall, carried on a short footing or cantilevered joists, to give a kitchen its island or a bath its shower. Small additions can fall under the village’s 150 square foot zoning exemption, yet still need a building permit.

Same open space
Second floors under 35 feet
Building up leaves the open-space share of the lot untouched, which helps where yards are already committed. Nashotah caps principal houses at 35 feet in its single-family districts, so the new roof is drawn to that height and an engineer confirms the walls and footings below.

Wooded outlook
Sunrooms toward the trees
A glass room toward the back of the lot, where a village lot opens onto a wooded yard or, near Nagawicka Lake and Forest Lake, toward the water. Three-season rooms stay unheated. Four-season rooms are insulated and heated to the energy code, and lots near the lakes get a floodplain map check.

Suites tied to sewer or septic
A bedroom, bath and living room, sometimes with a kitchenette and its own door. The drain route decides a lot here: sewered homes tie into the village line, while a house on a private system gets a Waukesha County soil and tank evaluation before a bedroom is permitted.

Budget drivers
What Moves the Price of a Nashotah Home Addition?
Size, foundation and the roof tie-in set most of the number, and a bath or kitchenette adds plumbing. A Nashotah job can add survey work for the footing certification and, off the sewer, a county septic evaluation. Both are found at the walkthrough and written into one price.

Surveyed footings
Nashotah Addition Materials, Footings to Siding
An addition has to ride out Wisconsin frost and snow load and still read as part of the original house. In Nashotah the footings are also measured by a surveyor before they are buried, so their position has to match the plan.
Frost-Depth Footings
Poured below frost and surveyed against the approved setbacks.
I-Joist Floor System
Long spans without bounce.
LVL Headers
Carry the load where the old wall opens.
Matched Trusses
Pitch set to meet the existing ridge.
Wrap and Flashing
Lapped over the old wall at the seam.
Siding Carried Across
Same profile and color on both sides.
Code-Rated Windows
Sized for daylight, egress and views.
Mini-Split Heat Pump
Heats and cools the room when the furnace cannot.

Young housing
Mostly Built Since 1990: Nashotah Houses Taking Additions
Nashotah’s housing is young for a village that began as a crossroads in the 1800s. It had 321 residents in 1960 and fewer than 600 in 1990; subdivisions in the 1990s doubled that by 2000, and over half of residents now live in homes built since 1990.
1990s Subdivision Homes
Part of the post-1990 growth, including Lake Country Estates south of Highway 16. Full basements and plain rear walls, so a family room or main-floor suite usually joins at the back.
Pre-1990 Village Houses
Ranches and split-levels from the decades after the 1957 incorporation. A single floor under a low roof, so the frame is checked before a second floor is considered.
Homes Built Since 2000
Truss roofs and poured walls, so the addition is detailed to what the original builder used and any subdivision rules are read first.
Old Crossroads Houses
A few older homes near Watertown Plank Road, where the village began. Old footings and framing are assessed before they carry new load.
Zoning and Recorded Restrictions
Village districts set yards, height and open space, and some subdivisions such as Lake Country Estates also carry recorded restrictions. John reads both before a plan is drawn.
Envelope and permits
Nashotah Home Addition Permits and Village Approval
Approval runs through the village itself, and the zoning district sets the envelope. R-1 lots need 25-foot side yards, 25 feet at the rear and 70 percent open space; R-2 lots 15-foot side yards and 75 percent. Houses in the planned unit districts follow yards set when the development was approved.
The village Building Inspector issues the building permit, and the zoning code bars anyone from using a new addition until the inspector also issues an occupancy permit. The village re-survey form has a surveyor certify footing forms against the permitted setbacks and elevations, with backfill held until the inspector confirms. A separate zoning permit with a certified site plan applies in some districts and to conditional uses, while work under 150 square feet that keeps the same use is exempt. Parcels off the village sewer add a Waukesha County septic evaluation when bedrooms are added. T And J files each step and books the inspections.

T And J's Nashotah Addition Process to Occupancy
A Nashotah addition moves through approvals, footings, shell, systems and finishes, and it ends with an occupancy permit rather than a handshake. Footings and framing are timed for unfrozen ground, so drawings and filings are started well ahead of digging.

Village questions
Nashotah Home Addition FAQ
Have a question about your own Nashotah lot? Call (262) 352-9525.
How close to the lot line can a Nashotah addition go?
It depends on the district. R-1 lots keep 25 feet at each side and the rear; R-2 lots keep 15 feet at the sides and 25 at the rear. Planned unit developments follow the yards set when they were approved. John measures before drawing.
Do I need a zoning permit or just a building permit?
Every addition needs a building permit from the village Building Inspector. A zoning permit with a certified site plan applies in certain districts and conditional uses, and work under 150 square feet that keeps the same use is exempt. T And J confirms which apply.
What is the footing survey the village asks for?
The village re-survey form has a land surveyor measure the footing forms against the permitted setbacks and elevations. Footings are not backfilled until the Building Inspector confirms the certification, so the survey is booked into the schedule.
We are on septic. Can we add a bedroom?
Usually, after a county check. Waukesha County asks for a Preliminary Site Evaluation, a soil test and tank capacity check, before permits for work that adds bedrooms on a private system. Homes on village sewer skip that step.
Is my 53058 address inside the village?
Not always. The village incorporated in 1957 and some nearby addresses that share the 53058 ZIP code sit in neighbouring municipalities with their own permit offices. John checks the parcel record before anything is filed.
How tall can a second-floor addition be?
In the RE-1, R-1 and R-2 districts a principal house is capped at 35 feet. A second floor on a single-storey ranch usually fits under that, but the new roof is drawn to stay under it, and an engineer confirms the structure below.
Does floodplain zoning affect a lot near Nagawicka Lake or Forest Lake?
Only if the parcel falls in a mapped floodplain. The village has its own floodplain zoning chapter, so for a lot near either lake the map is checked before the addition is sited, and a lot outside the mapped area proceeds normally.
When can we start using the new rooms?
After the final inspections. The village zoning code does not allow a new addition to be used or occupied until the Building Inspector issues an occupancy permit, so T And J schedules that sign-off as the last step of the job.
