DeForest, Wisconsin Building Permit Guide

In the Village of DeForest, building permits are issued through the Community Development office at Village Hall, 120 South Stevenson Street (608-846-6751), and the village’s building inspector, provided by General Engineering, reviews and inspects the work. Applications are filed online, and the village asks for 10 business days before your planned start. Under the fee schedule adopted by Resolution 2026-102, a new house pays $0.33 per square foot of floor area, with an $850 minimum.

What work requires a building permit in DeForest?

The village’s permit page casts a wide net: a building permit is required for all new residential or commercial construction and for any alteration or addition to the outside or inside of a building or property. Chapter 14 of the village code adds that no building may be put up, moved, enlarged, altered or demolished until the Building Inspector issues a permit with zoning approval from the Zoning Administrator.

Placement rules apply to every project: permanent structures may not sit in a public utility, drainage or stormwater easement or within the 75-foot wetland buffer, although fences are allowed in utility easements. Homes in Conservancy Place, Diamond Village, Fox Hills Estates, Heritage Gardens, Hidden Hills, Savannah Brooks and The Meadows need their homeowners association’s approval first, and a copy goes in with the application.

What DeForest decides and what the state holds

DSPS lists the Village of DeForest as a delegated UDC municipality (list current as of 9/24/2026), and section 14.06 adopts the Uniform Dwelling Code for all new one- and two-family homes, additions and remodeling, and the commercial code for the buildings it covers. The village decides the rest: fees, park and impact fees, zoning, a requirement that a lot front a dedicated street before any building permit, portable restrooms on construction sites, a 100-amp minimum electrical service and the plumbing and electrical permit rules in Chapter 14.

DeForest building department: who handles permitting

Community Development handles building and zoning permits, development applications, code enforcement and planning. The village’s Building Inspector comes from General Engineering and also acts as the village’s Electrical Inspector under section 14.28.

Anyone who disagrees with an order or ruling of the Building Inspector can appeal in writing to the Board of Zoning Appeals within 20 days.

DeForest permit types and filing documents

All village applications are online forms: the Building Permit Application, a Development Application, the Erosion Control and Stormwater (land disturbance) permit, Right of Way, Sign and Temporary Occupancy permits, and zoning determination letters. Decks, driveways, sheds, fences, additions and accessory buildings need a site map showing the house and other buildings, the project with its dimensions and the setback distances.

Residential permits

• New one- and two-family homes pay one construction fee by floor area that covers inspections of the house and everything built with it, such as garages, basements, decks and screen rooms, plus plan review (zoning included), erosion control, the state seal, a sewer lateral connection and a certificate of occupancy.
• Additions and large accessory buildings are priced per square foot with trades extra; smaller items such as decks, fences, patios, pergolas, sheds and pools have their own fees.
• Manufactured and HUD homes have a $420 fee plus $0.33 per square foot for basements, attached garages and decks.

Commercial permits

Multifamily, commercial and industrial projects carry separate construction, electrical, HVAC and plumbing fees by floor area, a $185 plan review and a $165 certificate of occupancy. New development also files the village’s Development Application, and the applicant pays the village’s planning, engineering and legal consultant costs on top of the listed fees; the village posts a guide on what to expect from that cost reimbursement.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning approval. Zoning review is included in the building permit fee for village parcels. A separate zoning permit is required only in DeForest’s extraterritorial zoning area in the Towns of Burke and Vienna.
• Site plans and conditional uses. Major site plans cost $300, minor site plans decided by the Zoning Administrator $110, conditional use permits $350 and rezonings $420 ($480 in the ETZ).
• Board of Zoning Appeals. Variances and appeals cost $450.
• Land division. Certified survey maps cost $300; preliminary plats $425 plus $2.50 per lot.
• Erosion control and stormwater. The village’s land disturbance permit is $100, and a stormwater management permit $100 where Chapter 24 requires one.
• Street and access. A dedicated street must border the lot, and right-of-way work, driveways, curbs and sidewalks need permits ($25 each).
• Floodplain. A floodplain zoning permit costs $150; DeForest participates in the National Flood Insurance Program (community 550082, map effective September 17, 2014).

DeForest building-permit fees and plan review costs

Fees come from the village’s Fee Schedule for Building and Development Applications and Permits, adopted by Resolution 2026-102 and effective August 18, 2026. The link on the permits page is still labeled with a 2023 date, but the file it opens is the 2026 schedule.

Worked example. A new single-family home with 3,000 square feet of floor area pays a construction fee of 3,000 × $0.33 = $990. Adding the items the schedule lists for a new one-family home (plan review $130, erosion control $165, state seal $50, certificate of occupancy $90 and a sewer lateral connection $550) brings the total to $1,975, before water used during construction and the park and impact fees set by village ordinance.

The schedule’s new-home section lists no separate electrical, plumbing or HVAC line, while additions and remodels say trades are not included; ask Community Development which trade charges apply to your house before budgeting. Water used during construction is billed under the DeForest utility’s Public Service Commission tariff.

Other charges on the schedule. Razing a house costs $110 per building and a commercial building $165, both including erosion control. Moving a structure starts with a $25 initial inspection and a $5,000 escrow. Permanent signs are $75 plus $1 per square foot, with a $170 electrical inspection for a new or upgraded sign service. A navigability determination is $350, an MMSD sewer service boundary expansion $175 and release of a village easement $125, plus any fees other agencies charge the village to review the request.

Trade permits and who may pull them

Chapter 14 sets DeForest’s trade rules, and the Building Inspector inspects all three trades.

Dwelling contractor credentials, electrician and plumber licenses and HVAC registration are state requirements (see Wisconsin rules).

How to apply for a DeForest building permit

Review, corrections and what causes delay

Most exterior projects need the site map, and a permanent structure drawn inside an easement or the 75-foot wetland buffer cannot be approved where it is shown. The code also bars a building permit on a lot without a dedicated street, and in most cases until sewer, water, grading and curb work are in the street, so check new subdivision lots early. An early start permit for grading, utilities and footings is possible once a complete application appears to comply, but only with an approved erosion control permit and stormwater plan where they apply.

DeForest construction inspections and closeout

The village’s building inspector from General Engineering carries out building, electrical, plumbing and HVAC inspections; Chapter 14 makes the contractor notify the Building Inspector when work is ready, and the village lists inspector@deforestwi.gov for the inspector. Plumbers must call when soil, vent, underground drain and final work is ready, and all work must stay exposed until it is inspected. New homes follow the Uniform Dwelling Code’s stages: foundation excavation and foundation, rough framing and trades, insulation and final, with erosion control checked at each visit.

• Electrical final: the power company will not connect a new service until the notarized final-inspection affidavit is on file.
• Final re-inspection: $50 per visit on a new home; $90 for each extra visit after corrective actions are ordered.
• Occupancy: a $90 certificate of occupancy for a new home; a temporary occupancy permit ($200 residential) lets you move in before final completion.

A building permit that needs more time can be extended for $30. Commercial additions, alterations and repairs pay $75 for each electrical, HVAC or plumbing inspection, and new commercial buildings a $165 certificate of occupancy.

Wisconsin building code

Wisconsin's Uniform Dwelling Code covers one- and two-family homes. Its Commercial Building Code covers public buildings, workplaces and buildings of three or more units. Local ordinances must conform to both. Wisconsin rules
