How much does it cost to add a bathroom to a commercial building?
A very basic bathroom could set you back $3,000 to $6,000, according to Cost Helper. It could attract additional costs if the location is far from water and sewage lines and if you need the help from a structural engineer. A plumbing permit will also be needed.
How is bathroom occupancy load calculated?
To calculate the occupant load, the first step is to calculate the area of the space in question by multiplying the length times the width – typically measured within the interior faces of the walls.

What occupancy type is a restroom?
