Do you need a building permit in Village of Waunakee, WI?

Village of Waunakee requires a Uniform Dwelling Code building permit for new single-family and two-family homes, including stick-built, modular and manufactured-home installations.1 Waunakee contracts with General Engineering Company for building inspection services; apply through the online application linked on the village’s Building Inspection page.2 New homes need footing, foundation and reinforcement, rough, insulation and final inspections; notify the inspector identified on the UDC permit.9 Do not start construction until you have the approved permit card.2

Who handles building permits and zoning in Village of Waunakee?

Contact Waunakee Building Inspection for building permit applications and inspection scheduling.2 The village accepts electronic applications from homeowners and contractors, reviews the application, and emails the approved permit after payment.2 Waunakee Community Development handles planning, zoning and code enforcement.10 Private septic and private-well permitting are handled separately by Public Health Madison & Dane County.4 A Waunakee home requiring private septic must have a sanitary permit before the village issues its building permit, so the sewage decision can affect the application sequence.5

Does Village of Waunakee have zoning and setback rules?

Village of Waunakee has zoning, with dimensional requirements that vary by district.36 In Waunakee’s R-1 district, the minimum floor area is 1,200 square feet per dwelling unit.7 R-1 principal buildings have front and rear setbacks of 20 feet and side setbacks of 6 feet on each side, totaling 12 feet.11 Waunakee’s A-1E district instead specifies a 40-foot front setback and 100-foot principal-building side and rear setbacks.12 Ask village Community Development to confirm the parcel’s district before designing the house or positioning outbuildings.10

How do septic permits work inside Village of Waunakee?

A new structure in Village of Waunakee that requires private septic needs a sanitary permit before the village building permit can be issued.5 Public Health Madison & Dane County issues sanitary permits and inspects private septic systems.4 Start with a soil evaluation by a licensed certified soil tester, obtain a design from a licensed professional, and have that professional submit the sanitary permit application.4 A Waunakee private sewage system cannot be used until the required sanitary permit, inspection and any required revised plan have been accepted and filed.13 Most systems need inspection every three years.4

Can you live in an RV or tiny home in Village of Waunakee?

We could not confirm a Village of Waunakee rule allowing residential RV occupancy or a complete tiny-home occupancy rule; ask village Community Development about the proposed use before buying a trailer or small house.10 A small primary home in Waunakee’s R-1 district faces the 1,200-square-foot minimum floor area per dwelling unit.7 Waunakee allows an accessory dwelling unit on a legal, conforming single-family lot in a district permitting single-family dwellings, subject to additional conditions.8 An ADU cannot exceed 900 square feet or 50 percent of the primary dwelling’s area, whichever is smaller, and detached ADUs have foundation, setback, parking and other restrictions.8

Building a home in Village of Waunakee: what comes first?

  • Confirm the parcel’s zoning district and proposed use with Waunakee Community Development; village district requirements differ.106
  • Establish the sewage approach: if the new home requires private septic, obtain the sanitary permit before the village building permit.5
  • Prepare the applicable village application materials, including construction and site plans, zoning approval, grading materials, impact fee form, erosion-control plan and heat calculations.2
  • Submit the electronic building permit application, complete review and payment, and wait for the approved permit card before starting work.2
  • Arrange the required UDC inspections with the inspector named on the permit.9

What should you check before buying land in Village of Waunakee?

Ask Waunakee Community Development to confirm the parcel’s zoning district and whether the proposed home fits its dimensional rules.106 We could not confirm a general village-wide public water or sewer connection threshold; ask the village about connection requirements for the address before planning private systems.10 For a proposed private well, Public Health Madison & Dane County requires a well location permit before construction.4 For land outside village limits, use the Dane County guide and confirm town adoption and any extraterritorial zoning: county zoning applies in covered unincorporated areas and excludes city or village extraterritorial zoning areas.14

Watch-outs

  • An R-1 primary dwelling in Village of Waunakee needs at least 1,200 square feet; ADU permission has separate conditions.78
  • We could not confirm residential RV occupancy in Village of Waunakee; ask village Community Development before planning to live in an RV during construction.10
  • For a new Waunakee home requiring private septic, the sanitary permit must precede the village building permit.5
