What is the maximum rise height for an exterior stair case in Boston?

I'm looking to build an exterior set of concrete or concrete block stairs and need to know the maximum rise allowed in the city of Boston.

The details ...

- Unattached to the building structure (essentially in a landscaping retaining wall)

- 3 feet wide

- will serve as the secondary means of egress from the rear of the property

How about minimum tread width while I'm at it?
