Lake County, Michigan Building Permit Guide

Lake County is one of the Michigan counties that runs its own construction code program, and the state’s list shows the Lake County Building Department enforcing all four codes in every township and in the villages of Baldwin and Luther. The office at 800 Tenth Street, Suite 110, Baldwin (231-745-2722) takes applications only by mail or in person, not by email, fax or online. A new house costs a $100 base fee plus $0.22 per square foot, and the department also issues the county’s soil erosion permits.

What requires a building permit in Lake County?

The county’s fee schedule is the clearest list of what it permits: new homes, additions and all alterations to houses; mobile and modular homes; garages, pole barns, storage sheds, decks and open porches; ramps; roofing; roofs built over mobile homes or travel trailers and pavilions; chimneys; demolition; multi-family and commercial buildings; and wireless towers.

The county checklist names Lake, Peacock, Pleasant Plains, Sauble, Sweetwater, Webber and Yates townships and the Village of Baldwin as locally zoned, so a land use permit from that unit comes before the county building permit there. Electrical, mechanical, plumbing and soil erosion permits are separate and are not included in the building fee.

What the county decides and what the state holds

The construction code is the state’s and cannot be changed locally. Lake County chose to enforce it, and the state’s Statewide Jurisdiction List marks the county as the enforcing agency for building, electrical, mechanical and plumbing work in every local unit. The county sets the permit fees, the filing rules and the inspection schedule, and runs the soil erosion program; zoning stays with the townships and the village that adopted it.

Lake County building department: who handles permitting

Every permit for construction in Lake County comes from one office, which some county forms call the Lake County Department of Building Safety and Permits. The state list shows the county covering all four trades in the townships of Chase, Cherry Valley, Dover, Eden, Elk, Ellsworth, Lake, Newkirk, Peacock, Pinora, Pleasant Plains, Sauble, Sweetwater, Webber and Yates, and in the villages of Baldwin and Luther; no township or village in the county runs its own building program.

To find the township for a parcel, or to get an address or proof of ownership, call Equalization at 800 Tenth Street, Suite 230 (231-745-2723, Monday to Friday 8:30 a.m. to 5 p.m.). Baldwin village has 1,025 residents and Luther 328 by the Census Bureau’s 2025 estimates; both are served by the county office.

Lake County permit types

The county posts separate building, electrical, plumbing and mechanical applications, spec-sheet cross sections for houses, pole buildings and garages, a roof loading data sheet, a residential energy efficiency sheet and the soil erosion application. Try to apply about two weeks before the planned start.

Residential permits

• New homes and additions: two copies of a sketch or prints with the spec sheet and cross section, a detailed site map of all buildings with dimensions, truss certification or a roof loading data sheet (snow loads are 50 and 60 pounds per square foot in most areas), and proof of compliance with the residential energy chapter.
• Owners applying themselves: a real estate summary sheet from Equalization proving ownership.
• Mobile homes: a copy of the title with the serial number (or the bank package for a new home), foundation and floor plans, a site plan and a cross section of any deck or landing.
• New houses: a blower door test is required.

Commercial permits

Commercial projects and projects under the Michigan Building Code need construction documents prepared by or under a registered design professional, and the plan review fee is paid when the application is filed. Commercial buildings are priced from a separate commercial fee chart, include up to four scheduled inspections, and multi-family buildings pay $100 per unit plus $0.22 per square foot.

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

What comes before the building permit

• Land use permit: from the zoned township or the Village of Baldwin, as listed above.
• Address: from Equalization; the county also issues 911 address signs on its own application.
• Well and septic: from the health department (231-745-4663, per the county checklist).
• Driveway: for new construction, a copy of the Lake County Road Commission permit (231-745-4666), or an MDOT permit for a drive onto a state highway (1-800-943-6368).
• Soil erosion: building within 500 feet of a body of water needs the county permit before any excavation starts.

Lake County permit costs and fees

Building fees come from the county’s Building Permit Fee Schedule, revised June 23, 2020; soil erosion fees from the county schedule effective October 1, 2023. All building permit fees are subject to plan review fees, and trade and soil erosion permits are charged separately.

Worked example from the residential line: a 2,400-square-foot new house is $100 plus 2,400 × $0.22 ($528), or $628, for up to six inspections. Plan review adds the $30 flat rate for that size and an energy review of at least $35, so the building permit comes to at least $693 before the trade permits and the $145 soil erosion permit where one applies. Building without a permit adds after-the-fact charges such as a $105 unscheduled site inspection and an $87.50 notification fee, and an after-the-fact soil erosion permit costs double.

Other charges on the 2020 schedule: wheelchair ramps are $25 under 300 square feet (one inspection) and $50 above (two inspections); a roof built over an existing mobile home, travel trailer or pavilion is $100 plus $0.15 per square foot for residential work and $0.20 for commercial; a wireless communication tower is $385 plus $117 plan review; a certificate of occupancy request on an expired permit is $50; a real estate letter with a certificate of occupancy is $100 plus time spent; and a Construction Board of Appeals hearing is $400. Commercial and multi-family plan review is one-third of the building permit fee, and over 3,500 square feet the same one-third rule applies to houses. Laminated all-weather permit cards are $2 extra.

Trade permits and who may pull them

The county issues the electrical, mechanical and plumbing permits in every Lake County township and village, on separate applications that ask for the state license and the local license where one exists. The building and trade applications each carry a homeowner affidavit: the owner certifies that the work will be done personally in the single-family home the owner occupies or is about to occupy, and takes responsibility for arranging inspections. Under the electrical affidavit, the owner’s wiring may not be enclosed, covered up or put into operation until the county electrical inspector has inspected and approved it.

• Inspection days: electrical on Monday, Tuesday and Wednesday; plumbing and mechanical on Tuesday and Thursday; building Monday to Friday.
• Electrical plans: not required when the service is 400 amps or less and the building 3,500 square feet or less; otherwise sealed plans are needed.
• Final approval: the building final is made only after the electrical, plumbing, mechanical, well and septic approvals.

How to get a building permit in Lake County

Review, corrections and what causes delay

Permits cannot be completed online, so the mailed or delivered package has to match the county’s required documentation list, including copies of the outside permits. The county’s documents give two validity rules: the 2025 handout and checklist say permits are valid for one year and can be extended in 180-day steps for $75 each, while the 2020 fee schedule and the 2006 permit holder notice describe 180-day permits extended the same way. The handout adds that a permit is cancelled when no inspection is requested or made within six months of issue or of the last inspection, and cancelled permits are not refunded or reopened. Refunds must be requested before construction starts, and the county keeps up to 25% (at least $60).

Inspections in Lake County

Call 231-745-2722 to schedule every inspection, with at least 24 hours’ notice; the person who signed the application is responsible for calling when the work is ready. Inspectors arrive between 10 a.m. and 4 p.m., so give access instructions when booking. If an inspector is locked out, the county charges $60 plus a $10 fuel recovery fee and inspects only after payment.

A residential permit includes up to six building inspections, and extra or failed inspections are $65 each. Before anyone moves in, all finals, including electrical, plumbing, mechanical and health department approvals, must be passed and a certificate of occupancy issued. Soil erosion permits expire one year after issue, and the county’s renewal schedule says the full original permit fee is paid again at expiry.

Michigan building code in Lake County

Lake County enforces the state code as the county enforcing agency named on the state list for every unit. No Michigan county is a National Flood Insurance Program community: each township and village joins on its own, so ask the township or village office whether a parcel near a river or lake is in a mapped flood area and which flood rules apply.

Michigan enforces one statewide construction code under the Stille-DeRossett-Hale Single State Construction Code Act (1972 PA 230); local units cannot amend it, and enforcement sits with the city, village or township, a county program or the state Bureau of Construction Codes, sometimes split by trade.
