Green Oak Charter Township, Michigan Building Permit Guide

Unlike most of Livingston County, Green Oak Charter Township enforces the construction code itself. Its Building Department at 10001 Silver Lake Road, Brighton (810-231-1333, ext. 7), where Al Hogan is Building Official, reviews plans in house, issues building, electrical, mechanical and plumbing permits and inspects the work, Monday to Thursday. Building permit fees follow the International Code Council’s construction value table; the Township Board adopted the February 2026 table and new department fees on May 20, 2026, effective June 1, and work started without a permit now costs double.

What requires a building permit in Green Oak Township?

Green Oak runs two permit types side by side: a land use permit for minor site work and small structures, and a building permit under the state code for everything structural. The zoning ordinance (Sec. 38-43) also says no excavation, construction, alteration or moving of a building, and no grading, leveling or re-contouring of more than 25 cubic yards, may begin until the proper permit is issued.

The shed limit is stated two ways. The Building Department’s April 2025 information packet says a shed under 200 square feet needs only a land use permit, plus a health department well and septic waiver, a Drain Commissioner waiver and a site plan; the ordinance table printed on the township’s land use form puts the line at one-story sheds of 120 square feet. Ask the department which applies before you order a shed between those sizes.

What Green Oak decides and what the state holds

The state’s Statewide Jurisdiction List shows Green Oak enforcing building, electrical, mechanical and plumbing codes locally, and the county’s building department says it handles no permits in Green Oak. The township sets its own permit fees, zoning and fire code: in 2026 the board adopted the 2021 International Fire Code in place of the 2009 edition, rewrote its accessory building rules (Ordinance 02-2026, May 20), adopted standards for High Resource Demand Facilities in April, and on October 7 passed Resolution 29-2026, a 180-day moratorium on data centers that the Planning Commission may ask to extend. A proposal to remove two parcels from the data center overlay map is on the November 18, 2026 board agenda.

Green Oak Township building department: who handles permitting

Everything goes through the township Building Department: plan review, permits, trade permits, inspections and certificates. The Planning & Zoning Department handles site plans, rezonings, special approvals and the Zoning Board of Appeals, and commercial site plans are reviewed off site by the township’s contracted engineer.

The township office itself uses a Brighton mailing address. Whatever the postal city on your deed, if the parcel lies in Green Oak Charter Township, file here rather than with the county in Howell.

Green Oak Township permit types

The department posts a building permit application, separate electrical, mechanical and plumbing applications (all three updated in May 2026), a land use application, a hold harmless agreement, a letter of authorization and an application for a rental or leased certificate of compliance.

Residential permits

• New single-family homes. Start with a township land use application, which the county needs before it assigns an address; then collect the county well and septic permits, the Drain Commissioner grading permit or waiver and the Road Commission driveway permit. File a plot plan with setbacks on all sides, point-on-line staking, walkout and final grades, neighboring building elevations and drainage; proof of ownership; signed energy calculations; three sets of plans showing wall sections, floor plans, elevations, foundation, door and window schedules, wall bracing, joists, headers and trusses; and a builder’s and driver’s license. Houses over 3,500 square feet need a sealed design.
• Additions, garages, finished basements and decks. Two identical plan sets, energy calculations for homes, a site plan with distances to lot lines, county well and septic and grading permits or waivers as the work requires, and a site inspection of the staked project before the permit is issued.
• Pools and hot tubs. Ordinance 02-2026 keeps pools out of front yards and required side yards, at least 10 feet from the rear line and 4 feet from buildings, inside a 4- to 6-foot fence set 4 feet from the pool wall with self-closing, self-latching gates; an above-ground hot tub or spa with a locking safety cover needs no perimeter fence.

Commercial permits

Commercial plans must be sealed by an architect or engineer, and new commercial sites go through the township’s site plan application and fee sheet, with the contracted engineer reviewing the site plan off site. Building plan review stays in house. Anyone may sign or pick up a commercial building permit with identification; trade permits are separate and must be signed by the licensed contractor.

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

What comes before the building permit

• Zoning: setbacks under the accessory rules adopted in May 2026 (5 feet from side and rear lines, 10 feet from the house and from any street right-of-way, one detached accessory building on most residential lots) and a ZBA variance if needed.
• Huron River corridor: the township posts a Natural River and Tributary Overlay permit application and a Huron Natural River District process for work in that district.
• County site permits: Drain Commissioner soil erosion or grading permit or waiver, Environmental Health well and septic permits or waivers, Road Commission driveway permit and a county GIS address.
• Homeowners association: if your development has an architectural review board, submit to it; the township can review plans at the same time but cannot refuse a permit that meets its ordinances.

Green Oak Township permit costs and fees

Green Oak prices building permits from the International Code Council’s table of average construction values, and until this year it used the 2024 table; on May 20, 2026 the board adopted the February 2026 table and the department’s fee updates, effective June 1. Fees are paid by cash or check when the permit is issued.

The trade applications dated May 2026 print a $60 non-refundable application fee, $60 rough and final inspections and a $15 registration, while the board’s change sheet lists the application fee at $50; confirm which applies to your form. The April 2025 information packet, published before the change, lists a $100 plan review deposit for a new house and flat amounts of $165 for a deck, $195 for a pool or hot tub, $160 for a demolition and $90 for a residential tear-off re-roof, with a $45 site inspection fee added to building permits; ask the department whether those amounts moved on June 1. Other township fees: a ZBA variance is $400 residential or $750 commercial, with $935 for a special meeting; a permit extension is $50 under the packet.

Trade permits and who may pull them

Green Oak issues its own electrical, mechanical and plumbing permits, each on a separate application. Examples from the May 2026 forms: on the electrical form a service up to 200 amps is $10 and a service inspection $60, circuits are $4, a generator $20, solar panels $15 (UL listing required) and an EV charger installation $120 including inspection; on the mechanical form a new home’s heating system is $80, air conditioning $25, a furnace $30, a gas fireplace $60 and a gas pressure test $60; on the plumbing form each fixture is $5, a replacement water heater $30 and a water service under 2 inches $5. Electrical plans are not required when the service is 400 amps or less and the building is 3,500 square feet or less.

Trade applications must be signed by the state license holder, whose license must be registered with the township ($15). A homeowner may sign residential building and trade applications with identification; the electrical form’s affidavit is for work installed by the owner in the home they live in or are about to occupy, inspected before it is covered. The packet reminds owners that anyone bidding $600 or more of work needs a state license, and that an owner who signs for a contractor or handyman takes on responsibility for the whole project.

How to apply for a building permit in Green Oak Township

Review, corrections and what causes delay

Incomplete applications are not processed, and staking without a point on line fails the site inspection, which then needs a re-inspection and another fee. A permit is closed when no inspection is requested within 180 days of issue or of the last inspection, a closed permit is not refunded, and re-opening it costs extra. The packet allows one six-month extension requested in writing before expiry for $50, with anything beyond 18 months at the Building Official’s discretion.

Michigan building code in Green Oak Township

Green Oak is the local enforcing agency for all four construction codes, so its Building Official applies the state codes directly; the township adds its own zoning, fire code adoption and property maintenance rules but cannot amend the construction code. FEMA’s Community Status Book lists Green Oak Township (community 260440) as participating in the National Flood Insurance Program, with maps dated September 17, 2008; flood zone approval is one of the sign-offs listed on the building permit application.

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.
