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

A new home in Village of Cambridge needs a Wisconsin Uniform Dwelling Code building permit; construction starts after the plans are approved and the permit is issued and posted.1 For additions and alterations, the state guidance says requirements vary by municipality, so bring the proposed scope to Cambridge’s building inspection office.12 Cambridge also requires a building inspector’s permit before construction, demolition or architectural alteration of buildings covered by its site, architectural and operations-plan chapter.10 An owner who occupies or will occupy the home may take out the UDC construction and erosion-control permits; that allowance does not remove the permit requirement.8

Who handles building inspection and zoning in Village of Cambridge?

Cambridge’s official building inspection page lists MSA Professional Services as the village building inspector and links to building-permit application forms.2 Contact the building inspection office for the application route and inspection arrangements for your project.2 For Cambridge’s current fee schedule, the village directs applicants to Village Hall.11 The village publishes conditional-use, site/architectural/operations-plan, variance and rezoning applications, so identify which approval your proposed use needs before preparing a full submission.12 For land outside village limits, use the Dane County guide: county zoning applies in covered unincorporated areas where the town adopted the county ordinance, rather than as Cambridge’s ordinary village zoning.13

Does Village of Cambridge have zoning, lot sizes and setbacks?

Village of Cambridge has its own zoning; the parcel’s district matters when sizing a home or laying out a building site.31415 Both R-L low-density residential and R-M single-family medium-density residential require at least 10,800 square feet of lot area.1416 R-L principal buildings need front and rear setbacks of 25 feet and side setbacks of 12 feet.15 R-M has the same individual minimums, but side yards must total 30 feet in combination.17 Maximum lot coverage is 30% in R-L and 50% in R-M.1819 In the A agricultural district, principal-building setbacks are 80 feet front and 50 feet side and rear; residential district dimensions do not describe that district.20

How do septic permits work inside Village of Cambridge?

For a private septic system in the Dane County portion of Cambridge, Public Health Madison & Dane County issues sanitary permits and inspects construction.4 Begin with a soil evaluation by a licensed certified soil tester, obtain a system design from a licensed professional, and have that professional submit the sanitary-permit application.4 Wisconsin POWTS plan review depends on the county’s delegated authority and project type; local permitting is conditional on approved plan review, and construction inspection follows the approval letter.52122 A new UDC dwelling using private septic cannot receive its building permit until the sanitary permit is issued.1 In the Dane County portion, buildings intended for human habitation or occupancy must connect where public sewer is available, as determined by the local sanitary district.23

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

Cambridge’s RV rule for private property in residential and commercial districts allows overnight sleeping for a maximum of 14 days in a calendar year and prohibits cooking at any time.6 The parked unit must belong to the resident; permanent sewer, water and electricity connections are prohibited, apart from the stated temporary-electricity allowance.6 That sleeping limit makes an RV unsuitable as an assumed residence throughout a home build.6 Cambridge requires detached single-family dwellings other than mobile homes to have at least 500 square feet of first-floor area, excluding laundry, workshop, furnace, bathroom, storage, closet and common-hall space.7 Manufactured homes in R-L and R-M must be double-wide, at least 24 feet wide and 36 feet long, with approved foundations and applicable design requirements.2425 We could not confirm a complete tiny-home or accessory-dwelling rule; ask Village Hall about the proposed structure and use.11

Building a home in Village of Cambridge: what are the steps?

Start with the zoning district and proposed use: Cambridge’s lot dimensions, setbacks and coverage limits differ by district.31519

  1. Ask Village Hall which zoning application and current fees apply to the proposal.1211
  2. Resolve public-sewer availability; on the Dane County side, obtain the sanitary permit first if a new home will use private septic.231
  3. Submit home plans through village building inspection and wait for plan approval and the issued, posted building permit before construction.21
  4. Complete required UDC construction inspections and receive a final inspection with no major health or safety violations before occupancy.2627

We could not confirm whether Cambridge requires a separate occupancy certificate; ask the village building inspection office before scheduling a move.2

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

For a proposed private well in Cambridge, obtain the state well construction notification before construction; the Dane County side also requires Public Health’s well location permit.94 For a driveway within the dedicated part of a public street under village jurisdiction, Cambridge requires the sidewalk permit described in its driveway chapter, with a drawing showing dimensions and materials; the driveway permit has no fee.28 A new connection to a state highway instead needs WisDOT approval.29 If you intend to split a parcel, Cambridge publishes a village land-division application and a separate extraterritorial application for land outside incorporated limits.30 Ask Village Hall to confirm the parcel’s zoning and building inspection to identify floodplain approvals before finalizing a site plan; Wisconsin floodplain development can require additional land-use and building permits.11231

Watch-outs

  • Cambridge’s RV sleeping allowance does not permit cooking or permanent utility hookups.6
  • Dane County’s public-sewer connection rule here applies to the Dane County portion of Cambridge; confirm the parcel’s county and service availability before relying on a private septic proposal.23
  • We could not confirm a Cambridge agricultural building-permit exemption; ask village building inspection before planning a barn without a building permit.2
  • Most private septic systems in Dane County require inspection every three years.4
