Do I need a permit in Riverview, Michigan?
Riverview, Michigan sits in Wayne County at the intersection of Climate Zones 5A and 6A, which means your frost depth runs 42 inches — deeper than much of the state. This matters for deck footings, shed foundations, and fence posts. The City of Riverview Building Department administers permits for all construction work, including new homes, additions, decks, pools, electrical upgrades, HVAC work, and most interior renovations. Owner-builders can pull permits for owner-occupied properties, which opens the door to DIY projects — but the permit requirement itself doesn't change based on who's doing the work. Riverview requires permits for nearly any structural, mechanical, or electrical work that alters the home's footprint, systems, or safety profile. The permit process is straightforward: file an application with plans, pay a fee based on project valuation, get a plan-review turnaround of typically 1-3 weeks, and schedule inspections at key stages. Small projects — like replacing a water heater or painting a room — generally don't need permits. Bigger questions live in the gray zone: a 10×12 shed, a 15-foot above-ground pool, a finished basement with egress windows. A quick call to the Building Department (search 'Riverview MI building permit phone' to confirm the current number) clears most of these up in 90 seconds and saves you the cost of rework or fines.
What's specific to Riverview permits
Riverview adopts the Michigan Building Code (MBC), which is itself based on the IBC with Michigan amendments and state-specific provisions. This means you'll see references to both the MBC and the IBC in permit paperwork and inspection notes. One key difference from national standards: Michigan's 42-inch frost depth in Riverview is actually more conservative than the IRC's typical 36-inch minimum for many northern zones. Deck footings, shed foundations, and fence posts all need to go below 42 inches to avoid heave in the winter thaw cycle — not just to the IRC minimum. This is especially important in Riverview's glacial-till soils (sandy in the north part of town), which shift with freeze-thaw cycles more aggressively than clay or rock.
The Building Department does not yet offer a fully online permit portal for initial filing as of this writing. You'll file in person at City Hall during business hours (typically Monday-Friday, 8 AM to 5 PM; verify locally before visiting). Bring a completed permit application, your project plans (hand-drawn site sketches work for small projects like fences or sheds; detailed architectural drawings required for additions or new structures), a description of the work, and estimated project cost (used to calculate the permit fee). Over-the-counter permits for simple projects like fence or shed replacements can be issued same-day if plans are clear and no violations jump out. More complex work goes to plan review, which averages 1-3 weeks.
Permit fees in Riverview are calculated as a percentage of estimated project valuation, plus a base filing fee. A rough guide: 1.5-2% of project cost, plus $50–$75 base fee. A $5,000 deck project typically costs $125–$175 in permit fees; a $25,000 addition costs $425–$575. Inspections are included in the permit fee — no per-inspection surcharge. Once your permit is issued, you'll receive an inspection card or notice listing the required inspection checkpoints. For new construction or major work, expect framing, electrical rough-in, mechanical rough-in, insulation, drywall (final inspection), and final inspections. For smaller work like a deck, you'll get a foundation inspection (after posts are in and footings are dug to correct depth) and a final structural inspection.
One common point of confusion: when the permit requires a licensed trade (electrical, plumbing, HVAC), homeowners often ask if they can pull the permit themselves and hire a licensed sub. The answer is yes — you (the owner-builder) pull the general permit, then the licensed electrician or plumber pulls a subpermit under your master permit. This is standard practice and doesn't disqualify you from the owner-builder exemption. However, the licensed trades still have to sign off on their work — they can't dodge licensing by working under your permit.
Riverview's inspectors typically schedule inspections 1-2 business days after you call or request them. In winter months (November through March), footing and foundation inspections can take longer because frost-heave risk is high and soil conditions change week to week. If you're pulling a permit for a shed or deck in the fall, expect that foundation inspection to slip into spring — plan accordingly. The Building Department keeps a basic record of permits on file, but doesn't maintain a fully searchable online database; if you need historical permit records for your property, call and ask the Building Department to pull the file.

Michigan context for Riverview permits
Michigan has a single statewide building code — the Michigan Building Code (MBC) — which is updated every three years. Riverview enforces the current edition adopted by the state. The MBC is based on the IBC with Michigan-specific amendments covering snow loads, frost depth, seismic risk, and energy code. One major point: Michigan allows homeowner permits for owner-occupied residential property. This means you can pull permits yourself if you own the home and will occupy it; you don't have to hire a contractor. However, some work still requires licensed trades — electrical, plumbing, HVAC, and gas work typically require a licensed contractor or a licensed sub under your permit. The homeowner exemption covers the act of pulling the permit, not the licensing requirement for specific trades. Michigan also has strong prevailing-wage rules on public-funded work (like school additions or municipal projects), but these don't apply to private residential work. Frost depth varies across the state; in Riverview at the border of Zones 5A and 6A, 42 inches is the standard — deeper than the IRC's 36-inch minimum for many zones — because Michigan's winter thaw cycles are aggressive. Building Department inspectors are certified through the Michigan Construction Code Commission and follow a statewide inspection protocol, so you'll get consistent enforcement across the state.
Common questions
Do I need a permit to replace my water heater or HVAC system?
No, not for a straight replacement in-kind. If your old water heater was electric, a new electric water heater of similar size goes in without a permit. Same with replacing an AC unit or furnace with the same fuel type and venting. However, if you're changing the system type (electric to gas, for example), converting venting, or touching the gas line or electrical service, you need a permit. Many homeowners save money by doing a like-for-like swap themselves, then having the licensed trade (plumber or HVAC) do the connection and inspection only. Always check with the Building Department if you're in doubt — a 10-minute call beats a costly inspection failure.
What's the frost-depth rule for Riverview?
Deck footings, shed foundations, fence posts, and any structure anchored to the ground must have posts or piers that extend below 42 inches in Riverview. This is deeper than the IRC's typical 36-inch minimum because Riverview's glacial-till soils and freeze-thaw cycles create heave risk. If you dig to 36 inches and frost pushes your deck posts or fence up over winter, the inspector will flag it at final inspection, and you'll have to re-do the footings. Get it right the first time: go to 42 inches or deeper, pack gravel at the bottom for drainage, and you won't have frost-heave problems.
Can I get a permit over-the-counter for a small shed or fence?
Yes, if plans are clear and the project is simple. Riverview Building Department staff can often issue a fence or shed permit the same day you apply, provided you bring a site sketch showing property lines, the location and dimensions of the structure, and proof that you own the property (tax bill or deed). More complex projects — additions, pools, electrical work — go to plan review, which takes 1-3 weeks. The faster route is to call the Building Department before you file and ask if your project qualifies for over-the-counter issuance. Many do.
How much do Riverview permits cost?
Permits are calculated as roughly 1.5-2% of estimated project valuation, plus a base filing fee of $50–$75. A $5,000 project runs $125–$175; a $25,000 project runs $425–$575. The fee estimate is based on the valuation you declare on the permit application. Be honest — undervaluing to save on permit fees invites closer inspection, and if the inspector suspects low-balling, they can demand a new appraisal. Inspections are included in the permit fee; there's no per-visit surcharge.
Do I need a licensed electrician to pull a permit, or can I pull it as an owner-builder?
You can pull the permit as an owner-builder (assuming the home is owner-occupied), but the licensed electrician has to do the electrical work and sign off on it. This is standard: you pull the general permit application, the licensed electrician pulls a subpermit under your master permit, and they perform and inspect their work. Many homeowners do the framing, carpentry, or drywall themselves, then hire licensed trades only for the systems work. This saves money and is fully legal — that's the point of the owner-builder exemption.
What happens if I build without a permit?
Best case: nothing, if no one notices. Worst case: the city discovers unpermitted work during a property inspection (often triggered by a sale or a complaint from a neighbor), forces you to tear it down or bring it into compliance retroactively, issues a fine, and requires you to hire a contractor to do it over with permits — costing far more than the original permit fee. Unpermitted work can also complicate home sales; lenders and title insurers may refuse to close. A $200 permit fee is cheap compared to ripping out a deck or shed you built wrong. Get the permit.
How do I find out if my project needs a permit?
Call the Riverview Building Department (search 'Riverview MI building permit phone' for the current number). Describe your project in 1-2 sentences: 'I want to build a 12×16 shed with a concrete foundation' or 'I'm adding a deck on the south side of my house, about 16 feet long.' The staff will tell you in 90 seconds whether a permit is required. This call is free, fast, and saves you the cost of rework or fines. Better than guessing.
Can I file my permit application online?
Not yet. As of this writing, Riverview Building Department does not have a fully online permit portal for initial filing. You'll file in person at City Hall during business hours (Monday-Friday, 8 AM - 5 PM, verify locally). Bring a completed permit application form (available at City Hall or by phone), your plans (hand-drawn sketches are fine for simple projects; architectural drawings for complex work), a description of the project, and estimated cost. Once the permit is issued, some jurisdictions allow you to request inspections by phone or email — ask when you file.
