Permits and inspections, cost overruns and change orders, warranties, scams, disputes and where to complain.
Most renovation budgets do not fail because the first estimate was bad; they fail because of hidden conditions, scope changes, unpermitted work, weak contracts or a contractor who stops showing up. This section explains the patterns behind those failures and what the law in your province gives you to work with.
Read about building permits and inspections, how cost overruns and change orders happen, what warranties actually cover, the red flags of renovation fraud, and the dispute route from a written complaint to small claims court or Quebec's Small Claims Division.
The official sources guide lists the government bodies, statutes and registers that matter (CRA, provincial consumer protection offices, the RBQ, lien statutes, municipal building departments) and what to check on each. We describe the pattern of common problems generically; we do not publish reviews, ratings or case studies of real businesses.
