Markham has been one of our active build areas across the Greater Toronto Area for years. From the established neighbourhoods of Unionville and Markham Village to the newer communities in Cathedraltown and Cornell, we've designed and installed sheds, studios, and pool sheds for homeowners across the city. Most of our Markham installs are completed in a single day, with structures prefabricated at our shop and delivered ready to use.

Markham homeowners tend to invest in their backyards thoughtfully. The properties are larger than central GTA lots, the landscaping is well-maintained, and the structures we install need to look like they belong on the property, not like they were dropped from a catalogue.
That's the kind of work we do. Every Markham build starts with a design conversation about what the structure needs to do, how it should look against your existing home and landscaping, and how it will be used day to day.
Practical reasons Markham homeowners work with us:
- Single-day installation means no extended construction zone in your backyard
- We handle the permit process for builds that need one, including engineered drawings
- We know the standard York Region site challenges: sloped backyards, mature trees, narrow side access — and plan delivery logistics around them in advance
- Post-install service is straightforward because we handle our own builds end to end, no third-party contractors
Whether you need a clean storage shed in Wismer Commons or a fully-finished home office studio in Unionville, the design and build process is the same: structure-first thinking, premium materials, and a finished product that works for decades.

Permits in Markham, Ontario
Quick Permit Notes
The City of Markham's accessory building rules align with the Ontario Building Code framework, with some city-specific details.
When a permit is required in Markham:
- Accessory structures larger than 15 m² (160 sq ft)
- Any structure that contains plumbing
- Any structure attached to another building
- Structural alterations or projects that change the use of a property
When a permit is typically NOT required:
- Single-storey detached accessory buildings under 15 m² (160 sq ft) with no plumbing
- Decks less than 600 mm (24 inches) above grade
- Replacement of existing structures of the same footprint
Important to confirm with the City: setback requirements, height restrictions, and lot coverage limits vary by zoning district. Most Markham residential zones require minimum setbacks of 0.6 to 1.2 metres (2 to 4 feet) from side and rear lot lines, with a maximum height around 4 to 4.6 metres.
We design most of our standard sheds at or below 160 sq ft (a 16 by 10 footprint maximizes the permit-free threshold). For larger builds or projects with plumbing or attached construction, we handle the permit process including engineered drawings and the site plan.
