New Custom Homes · Barrie
A new house in Barrie from one office: floor plans, structure, mechanical design and energy compliance, the permit, and a build coordinated by the team that drew it. We fit the house to By-law 2009-141, or to the older by-law some transferred land keeps, and file the set with the City of Barrie Building Services.

What’s included
A new house is the one project where every discipline is ours from the start. The structural sheet never fights the mechanical one, and the office that drew both coordinates the build. In Barrie the package goes to the City of Barrie Building Services, and it is drawn to that department’s checklist.

How it runs
Four steps from the lot to the occupancy permit, with one office answering for every drawing.
We walk the lot, check the zoning and any conservation or servicing constraints, and turn your brief or sketch into a first layout.
Architectural, structural and mechanical drawings developed together in one office, then filed for permit and followed through the city’s comments.
Excavation, foundation, framing, envelope, rough-ins and finishes by the builder we coordinate, with the engineer on site at each structural stage.
Final inspections, the occupancy permit, and a house built to the drawings you approved.

(416) 990-9179A building permit with architectural, structural, mechanical and energy-compliance drawings and a grading and servicing plan, plus any minor variance or conservation permit the lot triggers. The City of Barrie Building Services issues the building permit and, at the end, the occupancy permit, and inspects the build in between. Barrie has its own site alteration by-law, and we ask the City of Barrie Building Services early whether the earthworks around the new house need a permit under it.
If the lot is inside the regulated area of the Lake Simcoe Region Conservation Authority (LSRCA), yes. The west of the city is under the Nottawasaga Valley Conservation Authority. We check which authority maps the lot before anything else. Under Ontario’s Conservation Authorities Act, building a house or grading a site in hazardous lands, wetlands, river or stream valleys or shorelines at risk of flooding or erosion needs the authority’s permit, because O. Reg. 41/24 counts both as development. The authority has to publish maps of its regulated areas and review them at least once a year. We check the lot against the current map. Whichever authority’s permit the lot needs comes first, then the Barrie building permit.
Yes. We take on new custom homes across Barrie, including Allandale and Painswick, within an hour of our Richmond Hill office. The first consultation is free, by phone or on site.
Three things to start: lot address and a survey, if you have one; your sketch, brief or a plan from another designer; and whether the lot is serviced or needs a well and septic. Send those and we tell you what the City of Barrie Building Services will ask for before we quote.
Your zone’s limits on height, setbacks and coverage, found in Comprehensive Zoning By-law 2009-141 across most of Barrie and in the Community Planning Permit System inside the Allandale Major Transit Station Area. Ontario also shortens each minimum setback to 90 per cent of the written distance on urban residential land beyond the Greenbelt Area, so we confirm whether your lot qualifies before drawing the footprint. The City of Barrie Building Services then checks the house against the same limits.
We do, alongside the application for the new house. Taking a house down needs its own permit under Ontario’s Building Code Act, issued by the City of Barrie Building Services, and nothing can be demolished before it is. Clearing the lot and backfilling the old basement move a lot of soil, so we check that work against Barrie’s site alteration by-law at the same time.
Yes. Barrie allows the main home plus up to three additional units on a residential lot, inside the house, attached to it or in a coach house or garage, so a new house can be drawn with a basement unit and a detached one already in the plan. Building them in from the start is simpler than a retrofit: the ceiling height, separate entrances and fire separations are built once, and the water service and heating are sized for every household. The City of Barrie Building Services reviews each unit against the zone’s standards, so we check those first.
On a typical house lot, no, because By-law 2014-115 covers only trees in a woodlot of half an acre or more. A larger lot can contain a woodlot of that size, and a build tied to a development application brings the by-law in as well, so in either case we check the trees with the City before placing the house. Trees near the work still go on the site plan for the City of Barrie Building Services, since their roots limit where the foundation and the service trench can go.
Yes. Once we file the set, APLI shows where it stands with the City of Barrie Building Services and emails you each time it changes. A new house puts more in front of the examiner than a renovation does, with architectural, structural, mechanical, energy and grading sheets all reviewed, and we answer every comment and replace the sheets in that same application.
Check whether the LSRCA, or the NVCA in the west of the city, regulates any part of it, and whether its trees belong to a woodlot of half an acre or more, since either can move the house on the lot. The zoning matters too, because some land Barrie took in from Innisfil, Springwater or Oro-Medonte still follows that municipality’s by-law. We can look into all of it before your offer is firm.
Searched & answered
Short answers to the new custom homes questions people search most, and the broader topics they lead to.
Not covered here? Book a free consultationThe house sets it: its size, the finishes, the systems chosen and the site work the lot needs. Design and engineering are priced as separate lines from construction. Fine Engineering prices from drawings, so the quote comes after the free consultation, once there is a design to measure.
They can be. A builder repeating one plan across a subdivision can spread the design, engineering and approvals over many lots. A custom home carries those costs alone, and the owner’s choices of layout and structure add to them. Fine Engineering points out which design choices add cost as the first layout is drawn.
It depends on the lot and the house. Design and the permit come before construction, and once a complete application meets the Building Code’s criteria, the Code sets a statutory review period for a house permit. Fine Engineering gives a schedule with the quote and updates it as the municipality responds.
Usually because the heat reaching the room does not match the heat it loses. A room over a garage, or one with more glass and outside wall, loses heat faster, and a long or undersized duct delivers less air than the room needs. A room-by-room heat-loss calculation and a duct design show where the gap is. Fine Engineering does both for existing houses as well as new ones.
Yes. A new bathroom means new drains, vents and water supply, and installing or changing plumbing is building permit work with its own inspections. Replacing a fixture in the same spot usually is not. The drawing shows the drain, waste and vent layout the inspector will check. Plumbing drawings for bathrooms, kitchens and second units are part of Fine Engineering’s mechanical work.
Good to know
In Barrie the reviewer is the City of Barrie Building Services. Every Barrie lot sets its own terms: zoning, servicing, soil and any conservation authority permit decide what the lot allows before a plan is drawn.
We walk the site with the survey on a scheduled visit before anything is drawn, then file the new custom homes package to the City of Barrie Building Services’s own checklist.
Barrie has high-density waterfront condos built since the 1980s beside established suburban neighbourhoods. A custom home goes on one of the suburban lots, where the new house has to meet the grades and services already on the street.
On a teardown in one of Barrie’s established suburban neighbourhoods, the old foundation can look like a head start. Whether it stays is our P.Eng’s call, made by checking the concrete and whether the new walls and loads land where the old ones did.
There is a warranty side as well. Ontario warns that the Tarion warranties may not cover a new home sitting on old footings or an old foundation, so the foundation question is settled before the house is designed around it, and the City of Barrie Building Services reviews whichever way it goes.
On January 1, 2026, Barrie took in boundary land from Springwater and Oro-Medonte, and that land kept Springwater Zoning By-law 5000 or Oro-Medonte Zoning By-law 97-95. Some Secondary Plan land transferred from Innisfil in 2009 is in the same position under Innisfil’s By-law 054-04. A new house on any of it is sized to the older by-law’s limits, not to 2009-141.
The permit is still the City’s to issue, so the set goes to the City of Barrie Building Services, and its inspectors see the house through to occupancy.
