How the building code applies when you renovate

Most bathroom work is a renovation, not a new build — and a common misconception is that "it's just a renovation" means the rules don't fully apply. BBR handles alterations explicitly, and the honest answer is: the standard still applies, adapted to your building.

The requirements still apply

When altering a building, BBR's requirements apply to the extent reasonable for the work being done (section 1:22), taking the building's own conditions into account. The technical demands — moisture safety, safety in use, ventilation — don't disappear because a building is older; they're met through solutions appropriate to the existing structure.

Cautious, but to standard

Alterations must be carried out cautiously, respecting the building's character and detailing, while still achieving the required performance. For an older bathroom that often means solving the same moisture and safety goals by different means than a new build would use — but solving them all the same.

Why this matters for you

It's the reason a proper renovation upgrades a bathroom to current standards rather than simply replicating whatever was there before. A contractor who treats a renovation as an excuse to skip the moisture or safety rules isn't cutting you a break — they're leaving you with a non-compliant room and the risk that comes with it.
