Additions

A preliminary guide, not official approval. The department makes the final determination. Sources reviewed November 6, 2026.

Change project

What matters for this project.

Do not assume a small addition has a simplified permit or is exempt. New enclosed space is different from replacing an interior finish.

Tell the department what will be added and how the new space will be used. This guide does not determine engineering, design or application requirements.
