What is the function of a plumbing variance?

A plumbing variance serves the purpose of allowing modifications to the established codes when adhering to them strictly would create undue difficulty or an impractical situation for a particular project. This mechanism acknowledges that while codes are essential for safety, health, and efficiency, there may be unique circumstances that warrant flexibility.

For instance, a plumbing variance might be sought if existing site conditions, such as space constraints or unforeseen structural challenges, make compliance with a specific code provision problematic. By allowing for such adjustments, a variance enables compliance with the broader goals of the plumbing code while accommodating the practical realities of individual projects.

This aspect distinguishes the function of a variance from other options, as financial reasons or desires for uniform methods and simplicity do not adequately reflect the rationale behind issuing a variance. Variances are intended to address specific hardships rather than serve as a blanket allowance for deviations from the code.
