Custom Home Builders in Newmarket
Xavieras builds custom homes in Newmarket, where the approval path depends heavily on whether your lot sits in an older neighbourhood or a newer subdivision.
Newmarket Custom Homes: Two Very Different Paths Depending on Your Lot
Newmarket sits in York Region and is governed by the Town of Newmarket’s Building Services department, but where your lot is located within the town changes almost everything about your project timeline and approval complexity.
Older Newmarket versus newer subdivisions, not the same process
| Â | Established Areas (Central/Old Newmarket) | Newer Subdivisions (Woodland Hill, Stonehaven) |
Lot type | Older registered lots, some irregular shapes | Standard registered lots, more predictable |
Tree protection | Higher likelihood of protected trees, bylaw review required | Less canopy, fewer tree-related delays |
Zoning | R1/R2, variances more common | Generally as-of-right builds |
Demolition required? | Usually yes, replacing older stock | Often no, raw lot |
Permit complexity | Moderate to high | Low to moderate |
Conservation authority | Lake Simcoe Region Conservation Authority (LSRCA) applies near Holland River and wetland areas | Spot-check required by lot |

The LSRCA question applies here too
Newmarket has significant natural heritage features, including the Holland River, wetlands along the east side of town, and regulated areas under LSRCA jurisdiction. If your lot is within or adjacent to a regulated area, a separate LSRCA permit is required before the Town will issue a building permit. This is not a small delay. LSRCA reviews can add months if not identified and addressed early.
Three things to confirm before you finalize any lot in Newmarket
First, check whether the lot is in an LSRCA regulated area. This is available through the Town’s mapping tools or via a pre consultation. Second, confirm the existing zoning and what can be built as of right versus what needs a variance. Don’t rely on what the neighbour built. Third, if there are mature trees on the lot, get a preliminary arborist assessment before you design around them, since their protection zones will affect your footprint.

FAQ
Your Questions Answered
Exploring the nuances of building a custom home in Newmarket
How do I find out if my lot is in the LSRCA regulated area?
The Town’s mapping tools show whether a property falls within the Lake Simcoe Region Conservation Authority boundary, and a pre consultation confirms it. If your lot is regulated, LSRCA review runs alongside the Town permit, so we check this first on every project.
Is building in old Newmarket different from building in a newer subdivision?
Yes, meaningfully. Established central lots usually involve demolition, more tree protection review, and a higher chance of needing a variance. Newer subdivision lots like Woodland Hill or Stonehaven are typically as of right builds with more predictable timelines.
Do I need a variance for my build?
Only if the design exceeds the zoning by-law on setbacks, height, or coverage. Variances go through the Committee of Adjustment and add time, so we confirm what can be built as of right before design begins rather than after drawings are done.
What about trees on my lot?
Mature trees above a certain diameter are protected under the Town’s by-law, and their protection zones can affect your buildable footprint. A preliminary arborist assessment before design saves redesign later.
What costs sit outside the construction quote?
Demolition on infill lots, landscaping and site restoration, permit fees, development charges, arborist reports, and HST on labour are billed separately from construction. We map the full scope before you commit to a design.
