Legal Basement Apartments in Acton, Built and Registered Under Halton Hills' ARU Bylaw
Acton's older bungalow stock often needs underpinning to reach code ceiling height. We've underpinned more Acton foundations than most contractors see in a year, and we price that reality in from day one.

Acton falls under the Town of Halton Hills' Additional Residential Unit rules, the same bylaw that governs Georgetown, but the housing stock here is different in a way that matters for construction. Acton is built mostly around older bungalows and post-war detached homes, many on lots near the edge of the settlement boundary.
That means more of our work here is retrofit and underpinning, bringing an older foundation up to today's egress and fire separation standards, rather than building into a brand-new shell. We've built and registered ARUs across Acton, and we plan for the realities of an older foundation before drawings are even finalized.
Legal basement & ARU services in Acton
From the foundation assessment to registration, built for Acton's older housing stock.
Eligibility & ceiling check
We confirm your property is within the urban service boundary on municipal water and sewer, and assess ceiling height up front given Acton's common lower-basement stock.
Underpinning
Many Acton basements need the floor lowered to reach the 1.95-metre code minimum. We handle underpinning before framing, with the cost in the quote from the start.
Apartment construction
Once height is addressed, standard egress windows, fire separation, parking, and the 1.2-metre clear path to a side or rear entrance apply, same as anywhere in Halton Hills.
Permits & registration
We prepare the building permit under By-law 2010-0050 as amended by OPA 58, and after sign-off handle the ARU registration under By-law 2023-0060.
Basement renovations
Non-rental renovations for family rooms or extra living space, built to code so a future ARU conversion doesn't mean starting over.
Basement finishing
Flooring, drywall, lighting, and bathroom or kitchen finishes for Acton's mix of older and newer homes.
What a permit-ready Acton ARU needs
The same Halton Hills framework applies as elsewhere in the Town. Here's what has to be in place, plus the Acton-specific reality of older foundations.
The Acton-specific step: many 1950s and 60s basements sit below the 1.95-metre ceiling minimum, so underpinning comes first. We price that in up front rather than discovering it mid-project.
