A little more clarity

Common questions.

What should I ask before starting a interior renovation project?

Which parts of the renovation are finishes only, and which require building or trade permits?

Does this approve my property-specific project?

No. The published general guidance is verified; zoning, exact scope and other approvals still need to be resolved for your property.
