Custom Home Builder Innisfil

If you are looking for a custom home builder Innisfil is home to, here is the part most quotes leave out. The Town of Innisfil charges a new single detached house a town-wide development charge of $61,915, and then, depending on which service area the lot is in, an area water and wastewater charge of up to $63,925 more. Two identical houses can start more than $60,000 apart on paper because of the lots they sit on.

We are A&R Design Build. We have built custom homes and cottages across Central Ontario since 1973, and our model home and design centre are on Commerce Park Drive in Innisfil. This page explains what an Innisfil lot brings with it, and how we help you decide the house once you know.

The Town’s permit package for a new single family dwelling warns that development charges may be added to the permit fees, and the balance is due before the permit is issued. They belong in the budget on day one, not in the last month of planning. The Town of Innisfil publishes them by service area. The chart below sets out the figures for one single detached house from the Town’s pamphlet for developments outside the IDAG agreement, effective April 1, 2026.

Three things to take from it. First, the town-wide figure applies everywhere in Innisfil. It pays toward roads, parks and recreation, fire, police, the library and the rest of the Town’s growth services, and the single largest piece of it is roads and related, at $28,460.

Second, the area charge only applies where the service does. The pamphlet says the area schedules are collected for the services that are available, which is why a lot on a private well and septic system sits at the bottom of the chart. That does not make a rural Innisfil lot cheaper overall: you are paying for the well and the septic bed instead, and we put both in the site work quote.

Third, the chart is not the whole bill. The Town also collects education development charges on behalf of the Simcoe County District School Board ($3,711) and the Simcoe Muskoka Catholic District School Board ($2,372) per dwelling, and the County of Simcoe’s own development charge, which the County’s By-law 6930 sets at $14,975 for a single detached dwelling from January 1, 2026. All of them are indexed, the Town’s each April 1. When we price a custom home in Innisfil, we list these lines as the Town sets them, so you can see what is ours and what is not.

One more detail from the pamphlet is worth knowing if there is an old house on the lot. Demolish it and build within five years of the demolition permit, and the Town gives a credit against the new charge. The credit stays with the property.

If your Innisfil property has frontage on Lake Simcoe or is in Alcona, there is an extra step. The Town’s Community Planning Permit System, approved by Council in June 2025, applies to those residential properties, and the planning permit is issued before the building permit.

The Town sorts applications into three classes. A design that meets every standard is Class 1. Minor relief within set limits is Class 2. Anything beyond that is Class 3, where owners within 120 metres are notified by mail and have 15 days to comment. The Town says it will deem an application complete or incomplete within five business days.

For a custom home, that makes the design brief a planning decision. We read the standards for your Innisfil lot before the preliminary plans, so the house you fall in love with in 3D is one the Town can approve at the class you are expecting. Laura McAdam handles design, planning applications and municipal approvals for our clients, and on a shoreline lot that work starts at the first meeting.

The phrase new home builders in Innisfil covers two very different businesses: firms selling houses in a subdivision, where the lot, the plan and the finishes come as a set, and builders who design for the lot you bring. We are the second kind. We build on your lot or on one we help you evaluate, and the plan is fitted to that property rather than the other way round.

If you typed new home builders in Innisfil Ontario because you want something nobody else on the street has, start with our 82 plans across Country Classics, Country Retreats, Panoramics and Post & Beam, or start from a blank page. Every plan can be resized, reconfigured or flipped to face the view. The nearest finished examples of our work to Innisfil on our project page are two 2018 builds in Oro-Medonte, The Carlyle MKIII and The Bayview.
