Verified review from Google
It's been almost a year since I wrote my first review for King Street Construction. When I wrote that review, my tenant had just moved into the first ADU Kevin and the team had built for me. Since then, they've completed the second and third ADUs. I moved into the second one in September and the third one will be occupied tomorrow. The first two ADUs were the one-bedroom model and the third one is the two-bedroom model. All three ADUs are in Guelph. No matter what random changes the city added

ProScore profiles are built from publicly available information and official public registries, and scored using ProScore’s own methodology. We check this data against third-party sources and work to keep it accurate, but records change and errors can occur. A ProScore is informational only — it is not a guarantee, endorsement, or recommendation. Before hiring any contractor, you should independently verify and confirm all relevant credentials, licences, insurance (including WSIB coverage) and references directly with the contractor and the issuing authority. If something here looks wrong, let us know and we’ll correct it promptly.
