It depends. The renovation or one-level addition is exempt only if it meets all three items in the 3-rule test:
1. The area being renovated is less than the limits provided in Rule 10.3;
2. The construction does not adversely impact the mechanical or electrical system, structural integrity, or means of egress of any part of the structure; and
3. Does not change or conflict with the occupancy classification of the existing or adjacent space. Projects containing more than four dwelling units are subject to different requirements.
It is not exempt if the structure exceeds 30 feet in height, or exceeds table 503, Type V, column B in the state building code.
