Markham's 1980s–2000s subdivisions — Milliken, Berczy, Wismer, Greensborough — are full of homes reaching prime renovation age, with original kitchens and bathrooms ready for full updates. Basement finishing for rec rooms, home offices, and in-law suites is in constant demand.
In historic Unionville, renovations require extra care and sometimes heritage considerations — experienced contractors matter for these projects.

Yes, but properties in the Unionville Heritage Conservation District may need heritage permits for exterior changes. Interior renovations generally follow the standard permit process. Experienced contractors can guide you through it.
