Hartford, Wisconsin Building Permit Guide

Inside the City of Hartford, permits come from the city’s Building Inspection Office on the second floor of City Hall, 109 North Main Street (262-673-8277), where Building Inspector Mike Hedrick also serves as the electrical and plumbing inspector. DSPS lists the city as a delegated Uniform Dwelling Code municipality, and it reviews commercial plans with E-Plan Exam. Chapter 42 of the municipal code charges $0.40 per total square foot for a house, plus a $225 plan exam and a $2,250 refundable construction deposit.

What requires a building permit in Hartford?

Chapter 15 of the Hartford Municipal Code, the Unified Construction Code recreated by Ordinance 1435 in May 2021, says no construction, reconstruction, alteration, repair or demolition of any structure or structural appurtenance may be done in the city without a permit from the Building Inspector. The city’s permit FAQ turns that into a working list for homes and businesses.

Work done without a permit is charged triple fees under Chapter 42 and the FAQ, although section 15.06 still describes double fees for a first offense; the owner must also open walls or ceilings at their own cost if the inspector needs to see hidden work.

What Hartford decides and what the state holds

The state codes are adopted by reference in Chapter 15, which also adds city rules such as the plot-plan contents, the construction deposit and the basement wetness and flooding prevention standards in the city’s Standardized Development Specification Manual. Zoning (Chapter 52), signs (Chapter 54), floodplain zoning (Chapter 16), erosion control and stormwater (Chapter 20), the stormwater utility (Chapter 43) and historic preservation (Chapter 14) are local. Plan approval for commercial buildings is delegated to the city by DSPS, so the city’s consultant reviews them in place of the state.

Hartford building department: who handles permitting

The Building Inspection Office, part of the Community Resources and Development group at City Hall, issues building, HVAC, electrical and plumbing permits. Chapter 15 makes the Building Inspector the city’s electrical and plumbing inspector too. DSPS’s list of Uniform Dwelling Code agents, current as of September 24, 2026, shows the City of Hartford (listed in multiple counties) as delegated, so new one- and two-family homes are reviewed and inspected by the city. The Town of Hartford around the city holds its own separate delegation on the same list.

Zoning, site plans and occupancy sign-offs run through the Planning Department, led by City Planner Jacob Maas; a zoning administrator reviews most permit applications alongside the inspector.

Hartford permit types

Applications can be filed on the city’s iWorQ portal, at the inspection office on the second floor of City Hall, or by mail on request. Fences and most residential jobs use the city’s residential building permit application, and a site plan or survey goes with any exterior structure or structural change, while interior remodels need floor plans.

Residential permits

• New homes. Builders file the state’s online one- and two-family permit request required since Act 211, then drop off or mail the city’s new home package: the Wisconsin Uniform Building Permit Application, the state approval printout, an erosion control permit application and its conditions, the Public Works and utility voucher, the electric utility application, heating calculations, three color copies of the stamped plat of survey, two scaled sets of plans and a digital copy.
• Early start. A footing and foundation permit before the full permit costs $250 for a one- or two-family home; allow two full business days.
• Fences. A scaled site plan, the residential application, a drawing of the fence’s material, height and color, the fence information page and, if the owner builds it, the signed cautionary statement.
• Driveway expansions. A site plan, paving checklist and residential permit; the apron in the right-of-way needs a separate City Engineering permit.

Commercial permits

Hartford is a delegated municipality for commercial building, HVAC, plumbing, fire suppression and fire alarm plan review, done with E-Plan Exam, and the city says reviews finish within 15 business days of a complete package with fees. Chapter 15 sends every new commercial building, addition and alteration to plan review regardless of size, and any plumbing job of 10 or more fixtures. Applicants submit the city building permit application, the state or municipal review form, one electronic set of signed and sealed plans with specifications and calculations, and, before the permit issues, one paper set bearing the approval stamp of DSPS or the city’s consultant. New commercial buildings also pay the $2,250 deposit.

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. Check the parcel on the city’s GIS zoning map; site plans ($550) or site plan and architectural review ($750) go to the Plan Commission, and variances or appeals ($400) to the Zoning Board of Appeals.
• Land division. The city reviews certified survey maps and plats inside the city and, under its extraterritorial agreements with the Towns of Hartford and Rubicon, within three miles of its limits.
• Floodplain. Chapter 16 regulates building in mapped flood areas.
• Utilities and sewer. In-city sewer hookups pay a reserve capacity charge of $6,638 per residential equivalent connection in 2026, collected before the building or plumbing permit.
• Trees. Every new home permit carries a no-fee tree permit for the street trees the occupancy permit requires.

Hartford permit costs and fees

Hartford’s fees sit in Chapter 42 of the municipal code, recreated by Ordinance 1445 on October 12, 2021 and linked from the Building Inspection page as the current schedule. Several lines carry dated steps: the house rate is $0.40 per total square foot from 2025, $0.41 from 2028 and $0.42 from 2030. Every permit adds a $10 technology fee, and permits start at $75.

Valuations leave out heating, air conditioning, electrical and plumbing work, which carry their own permits. Plan review may be charged again when an expired permit is renewed, and a permit extension costs one-twelfth of the permit fee for each month added.

What a new house costs overall. The city’s 2026 New Housing Fee Report, which covers fiscal 2025, puts the fees on a 2,500-square-foot single-family home at $10,378: $1,950 for building, electrical, plumbing and HVAC permits, a $1,250 park fee, $175 erosion control, a $6,257 sewer hookup charge and $746 in other fees. Hartford has no separate impact fees. That report’s appendix prints lower rates than Chapter 42 ($0.35 per square foot, a $200 plan exam and a $1,000 deposit), and the 2026 sewer hookup rate in Chapter 42 is $6,638; budget with the Chapter 42 figures the city links as its fee schedule.

Trade permits and who may pull them

Hartford issues its own electrical, plumbing and HVAC permits, and the Building Inspector inspects them. The FAQ says electrical and plumbing applications must be signed by a licensed contractor and most building applications by a state-certified contractor; contractor requirements may be waived for certain projects on owner-occupied single-family homes, but never for duplexes or multifamily buildings.

• Electrical: permits go only to licensed master electricians, except to an owner wiring the single-family home they own and live in. New-construction wiring is $0.09 per total square foot; a new or changed service up to 400 amps is $55, a generator $100 and a solar system $150. The inspector must get 48 hours to inspect before wiring is covered or energized.
• Plumbing: permits go only to licensed master plumbers, with the same owner-occupant exception for a single-family home. New construction is $0.09 per total square foot plus $100 for gas piping; fixtures are $10 each.
• HVAC: new construction is $0.09 per total square foot; heating units are $55 each up to 150,000 BTU and air conditioners $75 up to 3 tons; a fireplace is $100.
• Fire protection: the Fire Department charges $150 for sprinkler plan review; commercial change-of-use or new-tenant occupancy ($125) is split between the Fire Department and zoning and building inspection.

How to apply for a Hartford building permit

Review, corrections and what causes delay

Missing documents or plans that need revisions restart the 10-business-day review clock for a new home. The Building Inspector may waive full plans for an alteration, repair or relocation costing no more than $2,000 that does not affect a critical life safety system. A house permit is valid for 24 months, other first-construction permits for 12 months (extendable to 24 if asked at application), and any permit lapses if work does not start within 120 days or stops for 60 days; an extension request must arrive within 15 days of expiry.

Inspections and occupancy in Hartford

Inspections are booked by calling 262-673-8277 or emailing inspector@hartford.wi.gov with at least 24 hours’ notice. They take place Monday through Thursday in a morning or afternoon window (the FAQ gives 10 a.m. to noon and 1 to 3 p.m.) rather than at set appointment times. A new home is inspected before footings are poured, before backfilling, before the basement floor is poured, and at rough carpentry, plumbing, electrical and heating before anything is covered. The surveyor’s recertification of the top of the foundation wall is due by the foundation inspection and truss plans by the rough inspection, or the city may fail the inspection or stop work.

When the house is ready, the builder emails the inspector for an all-finals inspection and tells the zoning administrator, which starts the sidewalk, driveway, curb box, lawn and tree inspections. The water meter must be in place first. Most first occupancy permits are conditional on lawn growth, a curb box recheck and street trees; the final occupancy permit follows once the lawn has been mowed at least once and the trees, sidewalk and driveway are in, and each failed check costs $75.
