What Medicine Hat publishes for additional units
Medicine Hat has dedicated guidance for secondary and backyard suites. The city explains when the use is permitted or discretionary and requires the applicable development, building and trade permits before the unit can be established.

Alberta: the provincial layer
Alberta’s building code has specific requirements for houses with secondary suites, while municipalities decide where suites are allowed through local land-use bylaws.

What kind of unit?
Define the unit form first. A suite inside the house is not necessarily regulated like a detached accessory dwelling.
Is the use allowed?
A general right to additional housing can still come with lot-specific limits. Check the address before treating the project as permitted.
Can the building comply?
Expect construction details such as egress, smoke/CO protection, ventilation and fire separation to influence the final layout.
Can the site serve it?
For backyard or garden units, test the site for setbacks, access, servicing and utility capacity before finalizing the footprint.
A better Medicine Hat planning order
A good sequence is property eligibility, unit type, building design, utilities/trades and inspections. Starting with finishes can hide the expensive constraints.
For resale properties, the most useful evidence is the municipal file, not the number of years the unit has been rented.
