Home Additions in Aurora

Home additions in Aurora, designed, permitted and built: rear, side and second-storey additions on postwar houses west of Yonge and on newer homes in the Bayview subdivisions. Our P.Eng checks what the existing foundation can carry, we draw the addition to Zoning By-law 6000-17, and the set goes to the Town of Aurora Building Division through CityView.

What’s included

Scope: what we take on, and what each part includes.

An addition is judged where it meets the old house: the beam that opens the wall, the roof that joins the existing one, the ducts that have to reach the new rooms. We design those joints first. In Aurora the package goes to the Town of Aurora Building Division, and it is drawn to that department’s checklist.

  • Cedar-clad entry addition with a standing-seam roof

    Ground floor and up

    Rear & side additions

    Kitchens, family rooms and bedrooms added at the back or side, on new foundations tied to the old.

    • Foundation & footings
    • Tie-in to existing structure
    • Roof junctions
    • Matching or contrasting exterior
  • Wood-framed addition going up against a house

    A second home in the house

    New duplex units

    Additions that create a separate unit, with the entrance, separations and services a second dwelling needs.

    • Unit layout & entrance
    • Fire separation
    • Second kitchen & bath
    • Separate metering options
  • Vaulted addition with exposed timber rafters

    Opening the old wall

    • Beam & column design
    • Foundation design
    • Second-storey load checks
    • Temporary shoring
  • Ductwork run across a ceiling

    Reaching the new rooms

    Mechanical tie-ins

    Heating, cooling, plumbing and electrical extended or upgraded so the addition is served as well as the original house.

How it runs

Process: 4 steps from first call to sign-off.

Four steps, with the slowest one, the tie-in to the house you are living in, planned around you.

  1. Site visit & zoning

    We measure the house and lot, check what the by-law allows and look at the foundation and framing the addition will connect to.

  2. Design & permit

    Plans and elevations, structure, HVAC and electrical from one office, filed with the city and answered at no extra charge.

  3. Build

    Excavation, foundation, framing and the opening into the existing house, then rough-ins, exterior and finishes, inspected at each stage.

  4. Close out

    Final inspection, permit closed, the house handed back as one building.

Client reviews

  • Engineering

    Alexander is everything you could possibly hope for in a professional engineer: exceptionally knowledgeable, meticulous, honest, reliable … If you are looking for an engineer you can trust completely, Alexander is the person you want on your project.

    Karl Sarkadi

  • Legal Basement

    I used them to get a permit from the City of Barrie to legalize my basement apartment … they took care of all the drawings and dealt with the city's requirements so I didn't have to stress about it. … what could've been a huge headache turned out to be smooth and painless.

    Anatoly Dobrovinsky

  • Basement + Entrance

    We had an outstanding experience working with Alexander on the legalization of our basement apartment, including obtaining approvals for a separate entrance. … His expertise in dealing with permits, building code requirements, and municipal approvals gave us complete confidence throughout the project.

    Robert Grin

  • Triplex HVAC Design

    Fine Engineering helped us with the mechanical and HVAC design for our triplex project in Barrie. The design included a boiler system for the 3 units and radiant floor heating … I’m very happy with the final result, it’s a really comfortable system during winter seasons.

    Vanessa L.

  • Duplex Conversion

    They converted my house into a duplex and did the permit drawings for demolishing walls for our open concept in the living room. Alex was nice to explain the zoning bylaws and the construction process during the renovation.

Before you call

FAQ: home additions in Aurora, answered.

Anything we haven’t answered here, we’ll answer on a call. The first consultation is free.

(416) 990-9179
  • The Town of Aurora Building Division handles the zoning check, the permit and the inspections; York Region looks after regional roads and servicing. The application goes in through the CityView Portal, which also shows its status and takes our inspection requests during the build.

  • If the lot is inside the regulated area of the Lake Simcoe Region Conservation Authority (LSRCA), yes, and the LSRCA permit comes before the Aurora building permit. The authority must publish maps of its regulated areas and review them at least once a year, so we check the current map against your survey.

  • Yes, if it fits the zoning, and that is the first thing we check. Aurora’s comprehensive zoning by-law is By-law 6000-17, which Council approved on June 27, 2017, completing the first comprehensive review of the zoning by-law since 1979. We read your zone’s setbacks, height and coverage from it, along with any site-specific exception on your lot. An addition that misses one of them goes to the Committee of Adjustment for a minor variance before the permit is filed.

  • It depends on whether your house is inside it. Aurora has one Heritage Conservation District designated under Part V of the Ontario Heritage Act: the Northeast Old Aurora Heritage Conservation District. For a house inside the district, we ask Aurora what it requires of an addition and design to that; outside it, the usual zoning and permit rules apply.

  • Yes. We take on home additions across Aurora, including Aurora Heights and Regency Acres, about half an hour from our Richmond Hill office. The first consultation is free, by phone or on site.

  • Three things to start: property address and a survey, if you have one; what you want to add and where; and photos of the side of the house and the yard where it would go. Send those and we tell you what the Town of Aurora Building Division will ask for before we quote.

  • It can, because new footings cut into the roots of any tree nearby, and Bylaw 5850-16 regulates injuring a tree as well as cutting it down. A heritage tree, or any tree on a lot in the Northeast Old Aurora district, needs a permit first, while on other lots up to two larger trees a year can go without one. We put the surveyed trees on the site plan before the footprint is drawn.

  • Yes. Registration By-law 6660-24 treats a unit attached to the house as an Integrated Unit, so an addition can hold one, registered with the Town as well as permitted. With a unit in the addition and another in the basement, the lot has its three units and no room left for a garden suite. We design the entrance, fire separation and exit into the addition from the start, so the Town of Aurora Building Division reviews one complete set.

  • It may. Your zone in Zoning By-law 6000-17 sets the lot coverage, and we read how the by-law counts a covered porch before either one is sized. If the two together go over, the choices are a smaller porch, a smaller addition or a minor variance from the Committee of Adjustment, and the Town of Aurora Building Division holds the permit until that is decided.

  • Often, yes. Houses west of Yonge went up long before Council adopted Zoning By-law 6000-17 in 2017, and an older house that sits closer to a lot line than the zone now allows can usually stay as it is. The new part is held to the current zone, though, or needs a minor variance before the Town of Aurora Building Division will issue the permit, so we measure the existing setbacks on the survey and keep the addition inside the ones 6000-17 sets.

Short answers to the home additions questions people search most, and the broader topics they lead to.

Not covered here? Book a free consultation
  • Size, storeys, how much of the existing house is opened and the finishes set it, so a figure given before there is a design means little. Foundation and structure are the fixed part and finishes the variable one, and a minor variance or a new heating system adds its own line. Fine Engineering itemizes the addition after the site visit.

  • It depends on what the addition adds: a bedroom, a bigger kitchen or a rental unit. The first two let the owner stay on a lot they already own, and a rental unit can also bring in income. Fine Engineering’s Director is a Broker of Record and can say what the new space may be worth at resale before the owner spends.

  • Once a complete application is in, Ontario’s Building Code gives the municipality 10 business days to issue a house permit or refuse it with reasons. Larger and more complex buildings get a longer period. The count only starts when nothing is missing, so an absent sheet or an unresolved zoning issue holds it back. Fine Engineering checks zoning and code before anything is submitted.

  • The application form, the drawings the Building Code calls for, and every other approval the project depends on. Zoning counts as applicable law, so a needed minor variance has to be granted before the permit can be issued, and a lot in a conservation authority’s regulated area may need that authority’s permit first. Fine Engineering assembles the whole package, with the designer’s registration details on the drawings.

  • Most often because the plans do not show that the work meets the Building Code or applicable law, such as the zoning by-law. A permit is also withheld when the law requires an engineer’s or architect’s design and the drawings lack one, or when the builder of a new home is unlicensed. The refusal must state its reasons, and Fine Engineering revises the set to answer each one.

  • Stop work and start on the drawings. A stop-work order usually means construction began without a permit or departed from the approved plans. Getting out of it takes a permit application that shows what was built and what is proposed, then whatever inspections the city asks for. Fine Engineering prepares those drawings and replies to the city’s letters.

Good to know

Home addition permits in Aurora

In Aurora the reviewer is the Town of Aurora Building Division. Every Aurora lot sets its own terms: setbacks, lot coverage, what the existing foundation can carry and where the roof will join decide the addition before the first drawing.

We walk the site with the survey, usually within a day or two of the call, before anything is drawn, then file the home additions package to the Town of Aurora Building Division’s own checklist.

Home additions in Aurora Heights and Regency Acres

Aurora has established postwar neighbourhoods west of Yonge seeing infill rebuilds, with newer subdivisions in the Bayview secondary plan areas to the east. On the older lots, where rebuilds are going up, we assess the foundation and framing so you can weigh adding to the house against replacing it. A newer subdivision lot usually has an approved grading plan, and a rear addition is designed to keep its drainage working.

Leaving room for a garden suite behind an Aurora addition

A deep rear addition and a garden suite compete for the same backyard. Registration By-law 6660-24 lets an Aurora lot hold one detached Ancillary Unit in the rear or interior side yard, but the yards and lot coverage in your zone of By-law 6000-17 still apply to both buildings. If a suite is a possibility, we lay out the addition and the suite on the survey together, so you size the addition knowing what it leaves.

Adding a storey to a postwar Aurora house

A second storey keeps the backyard free and puts the extra load on the house instead. In a postwar house west of Yonge we find out what the original footings and foundation walls are before designing anything above them, and add footings or reinforce walls where the new load needs it.

Your zone in By-law 6000-17 sets how tall the house can get, and in the Northeast Old Aurora district we ask the Town about the new roofline before the elevations are drawn.
