Converting duplex into triplex

[Adnan Dizdarevic]

Good day everyone,

Has anyone experienced turning a duplex into a triplex? Zoning is for multi family homes. House is currently registered as two but want to turn it into a three. Has anyone gone through this process before ? Does it take months to go through the town municipality? The house has all capability to be a three family. Attic is huge with walk up stairs on both sides and can be turned into a two bedroom.

Thanks
