Ten Days, Once the Town Has Everything
The Town of Innisfil reviews most house permits in 10 business days. Getting to the point where that clock starts is the real work, and it is work we do from our office in Innisfil.
An Innisfil building permit for a new house is not slow to review. The Town says most residential projects are reviewed within 10 business days. What takes time is everything that has to be true before those 10 days begin, because the Town counts from a complete submission, and several of the things that make it complete are not drawings at all.
We are A&R Design Build, based on Commerce Park Drive in Innisfil and building custom homes and cottages since 1973. Planning applications, permits and inspections are part of every build we take on. This page sets out how the Town of Innisfil process works, in the order it actually happens.
The Town reviews the application. It does not assemble it. Here is where the time goes, laid against the 10-day review.
Three items on the left decide most outcomes.
Which rulebook the lot is under. Residential properties in Innisfil with frontage on Lake Simcoe, or in Alcona, are under the Town’s Community Planning Permit System. There, the planning permit comes first and the building permit follows. Everywhere else, the drawings are checked against the Zoning By-law, and the Town advises reading it for size restrictions before applying.
Conservation authority clearance. The Town’s permit page is direct about it: the Ontario Building Code requires every regulated property to have written clearance from the appropriate conservation authority before a building permit application. In Innisfil that means the Lake Simcoe Region Conservation Authority or the Nottawasaga Valley Conservation Authority, depending on the property. Clearance is a separate application to a separate agency, on its own timeline.
The sealed lot grading and site servicing plan. For a new single family dwelling, the Town’s checklist asks for property lines, setbacks, existing and proposed construction and a zoning summary on a plan sealed by an Ontario professional engineer or Ontario land surveyor. It is usually the last consultant drawing to arrive, and the application is not complete without it.
The Town of Innisfil’s package for a new single family dwelling, in the order we put it together.
The application in Cloudpermit, a Schedule 1 designer information form for each design professional, and an owner’s authorization if an agent is applying for you.
Written approval from LSRCA or NVCA for a regulated property, attached at submission rather than promised later.
The lot grading and site servicing plan with the zoning summary, sealed by a P.Eng or OLS.
Floor plans for each level showing room uses, structural members and every plumbing fixture; elevations of every side with spatial separation; and a section through the footing, foundation wall and foundation drainage.
Heat loss and ventilation calculations, a heating floor plan with duct and register sizes, the SB-12 Energy Efficiency Design Summary and a mechanical ventilation summary.
The sealed truss layout and design sheets, the manufacturer’s floor framing layout, and design sheets for any member that needs an engineer, such as LVLs and point loads.
The Innisfil building permit fees start with a non-refundable application fee, paid in Cloudpermit before the application can be submitted: $200.50 for a residential project and $351.10 for commercial, industrial or institutional work. That fee is credited against the total. The balance comes from the Town’s building fees by-law, which is reviewed every year, and it has to be paid before the permit is issued.
For a new house, the permit fee is rarely the large number. The Town’s package warns that additional fees and development charges may be required, and on a new dwelling they usually are. A lot grading deposit is also collected with the permit fees on new home construction. On a single in-fill lot, the Town holds it until the Stage 2 lot grading inspection is approved, the engineer who designed the grading has sent a certificate, and the final inspection is accepted.
Our advice is the same on every Innisfil job: get the fee picture from the Town for your specific lot at the start, put every line in the budget, and do not treat the application fee as the cost of a permit.
A permit is not finished when it is issued. Town of Innisfil building permits stay open until a run of inspections is passed, and the Town lists the typical stages for a new house.
Two of these stages are easy to underestimate. The damp-proofing inspection has to happen before backfilling, so the excavator cannot close the hole until the inspector has been. And the lot grading inspections come at the very end, after the grass is established, which is why the Town recommends waiting on fencing and landscaping until the grading has been certified.
Along the way the Town may need third-party reports: Electrical Safety Authority inspections, a soil engineer’s report, a potable water report, a structural engineer’s report and the lot grading certificate. These go to the Town’s inspections inbox. On our builds we handle the permits and the inspections, and Darcy McMahon coordinates the construction schedule they have to fit into.
An Innisfil pool permit is a building permit for the enclosure, filed through Cloudpermit like any other, with a 10-business-day turnaround on a complete submission. In-ground and above-ground pools both need one. The rules come from the Town’s Fence By-law, 075-22, which sets the heights of lawful fences and requires owners of private pools to fence them.
The pool enclosure package asks for a site plan showing every structure on the property, including the house, sheds, decks, the septic system and the pool. The fence must be 1.2 to 1.82 metres high and at least 1.2 metres from the water’s edge, and gates must match the fence height and be self-closing, self-latching and lockable. A hot tub with a locking manufacturer’s cover needs no enclosure.
One point links the pool to the house. If your lot grading has not yet been certified, the Town says permission may be needed from the grading consultant, and it can ask for a grading plan from an OLS or P.Eng if the pool looks likely to affect drainage. On a new build, plan the pool after the grading certificate, not before. Pools are not among the services we list, but on a new Innisfil home we will show you where one could go without disturbing the grading.
Three permit triggers on the Town’s list that catch out owners of existing houses as often as new ones.
A new septic system, or a change to one, needs a permit. Adding fixtures, bedrooms or 15% more finished space calls for a written septic analysis. Properties within 100 metres of Lake Simcoe and other watershed waters are re-inspected every five years.
Site preparationThe Town lists accessory dwelling units as permit work with their own application package. A garden suite or second unit is a building permit, not a renovation.
Garages, ADUs and bunkiesAny new building larger than 10 square metres, or any size with plumbing, needs a permit. That covers most garages and many bunkies.
See what we buildYou can apply for an Innisfil building permit yourself. The Town accepts drawings from a qualified designer, an engineer, an architect or a knowledgeable property owner, and Cloudpermit is built to be used by homeowners. On a new house, though, the application is the sum of a designer, a surveyor or engineer, a mechanical designer, a truss supplier and often a conservation authority, and somebody has to make those pieces agree before the Town sees them.
On our builds that somebody is us. Planning and permit approvals are a step in our 12-step process, between the 3D renderings and your exterior selections. Laura McAdam leads design, planning applications and municipal approvals for our clients, and the Town’s building staff are at Town Hall, 2101 Innisfil Beach Road, in the same municipality as our model home.
If you are reading up on Innisfil building permits because you have a lot and a plan in mind, bring both to our model home. We will tell you which route the property takes and what the Town will want to see before anything is submitted.
Online through Cloudpermit, the system the Town uses for applications, payments, inspection requests and email updates. You create an account, choose the application type, upload the drawings and pay the non-refundable application fee before the application is submitted.
The Town lists a non-refundable application fee of $200.50 for residential projects, credited toward the total. The rest is set by the Town’s building fees by-law, reviewed every year, and is due before the permit is issued. A new house can also carry development charges, and a lot grading deposit that is refunded once the final inspection is accepted.
For most residential projects the Town’s review timeline is 10 business days, counted from a complete submission. Missing conservation authority clearance or an unsealed grading plan stops the application from being complete.
Yes. In-ground and above-ground pools need a pool enclosure permit through Cloudpermit. The plans must show the fence, its height of 1.2 to 1.82 metres, its distance of at least 1.2 metres from the water’s edge, and gates that are self-closing, self-latching and lockable. A hot tub with a locking manufacturer’s cover does not need an enclosure.
A new building larger than 10 square metres (108 square feet) needs one, and so does a building of any size with plumbing. A detached garage will almost always cross that line.
Yes. That is part of how we build. With your signed authorization for an agent to apply, we prepare and submit the applications, handle the back-and-forth with the Town and coordinate the inspections through to possession.
