Wondering how this project ended up? I’m a building designer and have put three apartment renovation projects through CDC. It’s been a steep learning curve, even for a professional. There now seems to be more certifiers who are familiar with the D&BPA but fees across the board for Class 2 work are high. Of the three approved I would say consent costs have been between 15-20% of build cost which is a monster sum – on a recent $450,000 renovation, adding an attic dormer to a building in a conservation area we’ve spent circa $70k just to get to construction.
