Building Permit Application

All properties within the Municipality of Calvin are building on private septic systems. The North Bay-Mattawa Conservation Authority (NBMCA) reviews and issues permits for septic systems within the municipality.
Permits are reviewed based on the size of the building, number of bedrooms and the number of plumbing fixtures. Please note that if you are planning on a renovation or addition to a building that will increase your overall house size by 15% or greater, the NBMCA must be notified and a septic system file review is required. Be sure to consult early to avoid potential delays.
