Custom Home Builders in Mississauga
Ground-up builds designed around the way you live.
For custom home builders in Mississauga, the lot writes most of the brief. A knockdown rebuild in Lorne Park, Mineola or Clarkson often means a generous lot whose zone table sets the envelope, a mature tree canopy and, on many streets, a creek, valley or the lake close enough to bring a conservation authority into the approvals.
Our luxury custom homes run from feasibility and lot assessment through design coordination with your architect, permits, foundation, framing, mechanicals, finishes and the final occupancy inspection. Our Master Builder and founder, Kash Varjavandi, brings 30+ years in construction to the schedule and the trades. Every ground-up home is enrolled in Tarion's new home warranty.

Knockdown Rebuild Economics in Lorne Park and Mineola
A rebuild makes sense when the land is worth far more than the house and renovating would still leave a dated plan. Construction typically runs $350–$650 per square foot, so a 3,000 sq ft home lands around $1.05M–$1.95M before land, design and soft costs; valley slopes, tree protection and long service runs push toward the top. Our guides to custom home costs and renovating vs rebuilding set out the comparison.
Zoning decides the envelope. An interior RL lot allows a 10.7 m ridge height, 35% lot coverage and a 20.0 m dwelling depth behind 7.5 m front and rear yards, and RL infill exception zones cap a detached house's infill gross floor area, counted above average grade and including an attached garage, at 190 m² plus 0.20 times the lot area. Designing to those numbers from the first sketch avoids a variance hearing.
Demolition, Trees and Servicing for a Mississauga Rebuild
Mississauga requires a Demolition Control Permit to demolish any dwelling unit. For a single house the Chief Building Official issues it with no fee, subject to standard conditions such as a rebuild timeline. The by-law lets that deadline be set no sooner than two years after demolition starts, and if it is missed the City can add up to $20,000 per demolished unit to the tax roll. Listed heritage houses need 60 days' notice first.
Tree permit applications tied to construction need an arborist report, and new or changed water and sewer connections need Peel Region approval: a site servicing drawing, a $400 residential first submission fee, and securities of $3,500 for water and $2,500 for wastewater as of 2026. Peel doesn't build the connection itself; the owner's contractor does.
Site Plan, Conservation and Tarion Steps in Mississauga
Site plan control is the approval rebuild owners rarely expect. Small residential projects are normally exempt, but a 2026 amendment to Mississauga's by-law removes that exemption in provincially prescribed areas: any parcel with any part within 120 m of a wetland, lake, river or creek, or within 300 m of an active railway line, light rail excluded. Lakeshore and valley lots need that check early.
When you own the land, Tarion treats the house as a contract home: the builder must hold HCRA vendor and builder licences and enrol the home before construction commences. Nexon's ground-up homes are enrolled, as our warranty page explains. For architect and builder under one agreement, see design-build for Mississauga homes; city-wide rules are in our Mississauga building overview.

Common questions
Do I need a demolition control permit to knock down my Mississauga house?+
Yes. Mississauga's Demolition Control By-law requires a Demolition Control Permit to demolish any dwelling unit, and the demolition building permit can't be issued until it is in place. For a single house the Chief Building Official issues it without a fee, though heritage-listed or designated properties face Ontario Heritage Act steps first.
How long does a knockdown rebuild take in Mississauga?+
Plan on roughly 2–6 months for design and permits and 5–14 months of construction, about 7 to 20 months overall. The front end stretches when a lot needs a minor variance, a Credit Valley Conservation permit, tree permits or Peel Region servicing approval, while finish level and complexity drive the construction side.
Can I remove trees to fit a new house on my Mississauga lot?+
Only with a permit. The City's Private Tree Protection By-law covers every tree on private land measuring 15 cm (6 inches) or more across, dead or dying ones included. The City currently lists a base fee of $399.77 including HST, plus $139.72 per additional healthy tree, and the City generally asks for one replacement tree for every 15 cm of trunk diameter removed.
