Why Ajax homeowners choose BCR

20+ Years Building in Ajax and Durham Region

Ajax is one of the fastest-growing municipalities in Durham Region, and rental demand tracks that growth. Proximity to the 401 corridor and Ajax GO keeps legal suite occupancy strong, and buyers in this market actively look for income-producing properties, which shows up in resale.

The Town of Ajax issues building permits for all residential renovation work. A secondary suite permit in Ajax has to satisfy both the Ontario Building Code second unit provisions and the Town zoning by-law. BCR knows the Ajax approval path and manages applications, drawings, and inspections through to sign-off.

Ajax homes built in the 1980s and 1990s, particularly through South Ajax and Pickering Village, often have lower ceiling heights than newer builds. Some of those need an underpinning assessment before a legal suite can be confirmed at all. That determination happens during the Feasibility Assessment, before a dollar is committed to construction.

Local coverage: BCR serves every Ajax neighbourhood including South Ajax, Pickering Village, Harwood, Central Ajax, Central West, Northeast Ajax, and Carruthers Creek. Every project starts with a Feasibility Assessment where we walk your property, confirm what is possible, and give you a real investment range before you commit to anything.
