Under what conditions can a chief building official issue a conditional permit?

A chief building official can issue a conditional permit when it is necessary to prevent unreasonable delays in the construction process. This typically occurs when certain requirements of the building code cannot be fulfilled before the work begins, yet not issuing the permit would halt progress on the project, potentially leading to additional costs or logistical issues. The conditional permit allows developers to start construction under specified conditions while ensuring that remaining requirements are understood and are eventually met.

The other options do not appropriately justify the issuance of a conditional permit. Simply meeting all standard permit requirements would negate the need for a conditional permit. Submitting plans within 24 hours is not a stipulated condition for permit issuance; proper documentation has to be provided according to the usual timeframes and standards set out in the building codes. Similarly, the location of the project site, whether urban or otherwise, does not inherently justify the need for a conditional permit; it is the circumstances surrounding the project that matter most.
