Do you need a building permit in the Town of Germantown, Wisconsin?
Yes. Before covered construction begins in the Town of Germantown, the owner or agent must obtain both a Town zoning compliance permit and a building permit issued through GEC.1 The building-permit trigger covers new buildings, additions that enlarge a building, covered structural or building-system alterations, and major equipment replacements.10 Repairs that restore an installation to its previous code-compliant condition may be exempt when the building inspector so determines.10 The Town has adopted Wisconsin building codes for dwellings, commercial and apartment buildings, pools, garages and most outbuildings, with a stated exception for certain play structures, dog kennels and storage sheds under 200 square feet.11
Who issues building and zoning permits in the Town of Germantown?
The Town of Germantown issues the zoning compliance permit, and General Engineering Company issues the building permit.12 The Town directs applicants to submit the zoning application to the Town office and the building application online to GEC.4 A complete Town application includes a site plan, proof of ownership and any applicable Juneau County sanitary or shoreland approval.4 The zoning administrator acts on the application within 14 calendar days after receipt and gives written reasons for a rejection.4 Contact the Town zoning office at 608-562-5751 for zoning questions and GEC building inspection at 608-745-4070 for building-permit questions.1213
Does the Town of Germantown have zoning?
The Town of Germantown administers its own zoning ordinance, with ARO Agricultural/Residential/Open Space, Town Center, Commercial, Business Center Mixed Use, Shoreland Overlay and Planned Unit Development districts.1415 The parcel's district matters: ARO permitted-use lots generally require at least 3 acres and 300 feet of width at the building setback line.16 Town Center single-family lots served by sanitary sewer generally require at least 20,000 square feet and 100 feet of width, while lots without sanitary sewer generally require 3 acres.17 The Town's permit packet states setbacks of 10 feet from a side lot line, 30 feet from the rear lot line and 30 feet from the front lot line, or 63 feet from the road centerline, subject to additional district and shoreland rules.18
How do septic permits work inside the Town of Germantown?
Juneau County Zoning and Sanitation administers sanitary permitting for private sewage systems inside the Town of Germantown.3 Every private sewage system requires a separate complete application signed by a licensed plumber and a sanitary permit before covered installation, replacement, reconnection or modification work begins.5 New homes, replacement homes, connections to existing septic systems, bedroom additions and qualifying large additions can trigger the sanitary-permit requirement.19 The system must remain open for inspection, and covered new or reconnected systems must be installed, inspected and approved before the structure is occupied.2021 Juneau County soils rate poorly for conventional drain fields almost everywhere, so budget for site evaluation and the possibility of a mound or engineered system.22
Can you live in an RV or tiny home in the Town of Germantown?
The Town of Germantown limits use of a camper vehicle or other non-permanent structure as living quarters for more than 30 consecutive calendar days in a year unless it is in a licensed and authorized campground or mobile-home park.6 The Town's camping rules also require a camping permit, limit ordinary placement to one unit per parcel and require at least 3 acres.6 Camping while constructing a single-family dwelling may continue for up to one year only when the required building, foundation or slab, camping and waste-disposal conditions are met.6 A Germantown zoning compliance permit will not be issued for a dwelling with less than 816 square feet on the ground level.7 The Town does not expressly classify tiny homes as a distinct use, so ask the zoning office how a proposed unit will be treated before buying or ordering one.
Building a home in the Town of Germantown: what are the steps?
- Confirm the parcel's Germantown zoning district, dimensional rules and whether county shoreland or floodplain review applies.1523
- Obtain the Juneau County sanitary permit and any required county shoreland approval before Town zoning approval.4
- Prepare the site plan and proof of ownership, then submit the zoning compliance application to the Town and the building application to GEC.4
- Obtain a Town driveway permit before establishing or materially altering covered access to a highway or right-of-way in Germantown.9
- Begin construction only after the zoning compliance and building permits are issued.1
- Keep covered septic work open for county inspection and do not occupy the building until the building inspector allows occupancy.2024
What should you check before buying land in the Town of Germantown?
Check the Town zoning map because lot size, allowed uses and dimensional standards vary by district.15 Land within 1,000 feet of a lake or flowage, within 300 feet of a navigable river or stream, or in a floodplain is subject to Juneau County shoreland review before construction.25 County shoreland rules generally require buildings and structures to stand at least 75 feet from the ordinary high-water mark, subject to stated exceptions.26 Only 0.5% of Juneau County soils are rated without severe limitations for a conventional septic drain field, making soils and septic feasibility an early due-diligence item.22 The ordinary private-well permit path in Germantown could not be confirmed; ask the Town zoning office and the Wisconsin Department of Natural Resources before relying on a parcel's water plan.
Watch-outs
- A Town zoning compliance permit does not replace the separate GEC building permit or a required Juneau County sanitary or shoreland approval.4
- A manufactured home is prohibited in the Town Center District, but the reviewed rule does not establish the placement rule in every other Germantown district.27
- Non-plumbing sanitation may be permitted only where there is no indoor plumbing and the structure is not used as a full-time residence.28
- Development in a mapped Juneau County floodplain requires a land-use permit before covered construction, repair, modification, addition or change of use begins.29

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
