Do I need a permit for a small deck or patio?

Decks over 200 square feet or higher than 24 inches above grade require a permit. Small ground-level patios (poured concrete, pavers, wood platforms under 12 inches high) are typically exempt if they're not attached to the house. Attached decks always require a permit regardless of size because they're considered part of the structure.

How deep do footings need to be in Lansing?

All footings must extend below 42 inches to clear Lansing's frost line. Frost heave — the upward pressure from frozen ground — will move a footing that bottoms out above 42 inches. This is why footing inspections are critical; the inspector will measure from grade to the bottom of the footing to verify it clears the frost line.

Can I file my own permit as a homeowner?

Yes, owner-occupants can pull permits for work on a primary residence. Licensed trades (electrical, plumbing, HVAC, structural) still require a licensed contractor to sign the permit, but you can file the paperwork yourself and save the contractor fee. The building department will walk you through the application if you come to the counter.

What's the most common reason a Lansing permit gets rejected?

Missing or incorrect site plan. The plan needs to show property lines, setback distances, the location of your work, and the location of existing structures. If the plan doesn't match your description, or if the work violates setback requirements, the permit will be bounced. A survey takes 2-3 weeks and costs $300–$600, so budget that time before you file.

How long does plan review take in Lansing?

Simple permits (fence, electrical subpermit, water-heater swap) are often approved over-the-counter in 1–2 days if filed in person. Complex permits (additions, new construction, structural changes) typically take 3–4 weeks. The building department will email you a review comment letter if revisions are needed; you can often resubmit through the online portal without returning to the office.

Do I need a survey before I file?

Yes, if your project sits close to a property line or if the permit application asks for setback verification. A survey shows the exact property boundaries and the location of your proposed work. If you're adding a deck 6 feet from the rear line in a zone that requires 10 feet, you need a survey to prove the violation before you can apply for a variance. Many contractors will tell you the lot size and boundary location from the deed or tax records, but that's not a substitute for a survey when setback is tight.

What happens if I skip the permit?

Unpermitted work can kill a home sale. The buyer's inspector or the buyer's lender will catch it during financing. Your title insurance may deny a claim if the work was done unpermitted. The building department can issue a violation notice and order unpermitted work removed. Insurance claims for unpermitted work may be denied. A permit costs $100–$300; removing unpermitted work or defending a violation costs thousands.

Can I hire a contractor from out of state?

Contractors from out of state must be licensed in Michigan to sign permits. They can work in Lansing as long as they have a valid Michigan contractor's license. The permit application will ask for the contractor's license number. If the contractor doesn't have one, they can't sign the permit, and you'll need a Michigan-licensed contractor to pull the permit and take responsibility for the work.

Complete Guide to Building Permits in Lansing, MI (2026)

Do I need a permit in Lansing, MI?

Lansing's building department enforces Michigan's Residential Code and Lansing's local zoning ordinance. The 42-inch frost depth sets the baseline for deck and foundation footings — go shallow and your structure will heave out of the ground when the ground freezes in November. Most residential projects — decks, additions, electrical work, HVAC replacement — require a permit. The building department processes permits through the City of Lansing's online portal, though plan review timelines vary by complexity. Owner-occupants can pull their own permits for work on their primary residence, but that doesn't mean you skip the permit; it means you file the paperwork yourself instead of paying a contractor to do it. Lansing sees a lot of rehab work in the central neighborhoods, which means the building department is used to renovation permits and knows the dance between historic preservation, code updates, and practical construction. Get familiar with your frost depth, your setback requirements from your lot boundaries, and whether your work is exempt or over-the-counter. Most rejections come from missing survey data, incorrect valuations, or setback violations — all fixable before you submit.

What's specific to Lansing permits

Lansing adopted the 2015 Michigan Residential Code, which aligns closely with the 2015 IRC but includes state amendments. The 42-inch frost depth is non-negotiable for footings — the frost line in Lansing sits below 42 inches, and the code requires all footings to extend below the frost line to prevent frost heave. Deck footings, shed footings, anything that bears weight and sits in the ground needs to bottom out below 42 inches. This is why Lansing frost-heave season (October through April) sees a flurry of footing inspections in May and June, after the ground thaws and contractors can verify their work didn't shift.

Lansing's building department uses an online permit portal accessible through the city's website. You can search for your property, check permit history, pull copies of old permits, and in some cases file over-the-counter permits directly. The portal is faster than walking in, but many simpler permits (fence permits, small electrical work, water-heater swaps) move more quickly if you stop by the Building Department desk in person before 3 PM on a weekday. Staff can do a same-day review for routine exemptions and low-complexity work.

The city enforces a local zoning ordinance on top of the state code. Setback requirements vary by zone — residential neighborhoods typically require 25 to 50 feet from the front property line and 5 to 10 feet from side and rear lines, but this changes in downtown zones and near commercial corridors. Additions, decks, sheds, and fences all trigger setback review. If your project sits close to a property line, you'll need a survey or at minimum a site plan showing the lot boundary and the location of your work. This is the #1 reason additions get flagged in Lansing: the homeowner assumes the existing wall is the property line, but it's not. Get a survey before you file.

Lansing sits in climate zones 5A and 6A depending on location (north part of the city is 6A, south is 5A). This affects insulation requirements for additions and new construction. If you're adding a room or finishing a basement, your insulation spec needs to match your zone. The building department's permit-application checklist will specify this, so don't guess.

Owner-occupants can pull permits for work on a primary residence without a contractor's license. This is useful if you're doing the work yourself or hiring a handyman. But the permit itself still needs to be filed, the work still needs to pass inspection, and you're still liable if something goes wrong. The building department will not sign off on work that fails inspection, and the final CO (certificate of occupancy) won't issue until inspections pass. Don't skip the permit and hope nobody notices — code violations can kill a home sale, trigger liability issues, and make insurance claims denied.

Most common Lansing permit projects

These are the projects Lansing homeowners ask about most often. Each has its own threshold, fee structure, and inspection schedule. Click through to the detailed guide for your project.

Decks

Decks over 200 square feet, or any deck that rises more than 24 inches above grade, require a permit in Lansing. Your footings must reach 42 inches below grade to clear the frost line. Common rejection reason: site plan doesn't show setback distance from property line — get a survey.

Roof replacement

Roof replacement and re-siding are permit-exempt in Michigan if they don't change the structural design or roof height. However, if your existing roof is load-bearing (most are), structural changes require review. Check with the building department before you bid if you're replacing rafters, trusses, or adding insulation above the wall line.

Electrical work

New circuits, panel upgrades, hardwired appliances (new AC unit, heat pump, water heater), and any 240V work require a permit. Licensed electricians file most electrical permits, but owner-occupants can file for their own primary residence. Subpermit fee is typically $75–$150.

HVAC

Furnace, heat pump, or air-conditioner replacement is typically permit-exempt if you're doing like-for-like replacement and the unit sits in the same location. If you're moving the unit, changing ductwork, or upgrading to a different capacity, a mechanical permit is required. Most HVAC contractors will coordinate the permit for you.

Room additions

Any room addition requires a permit and triggers setback review, electrical/HVAC updates, and structural inspection. Plan for 4-6 weeks of plan review if your addition touches the existing roof or changes the electrical panel. Valuations typically run $100–$150 per square foot for plan-checking fees.
