*This is a voluntary smoke and carbon monoxide alarm verification procedure. If you prefer a building inspector to
perform the verification, you must arrange to have an adult present at the time of inspection.
*Note, this verification is only used when normal access to the interior of the dwelling is not achieved during the course
of project construction. It is normally used for projects such as re-roofing, re-siding, patio covers or swimming pools.
