Moderate to High (Requires proficiency in excavation, concrete pouring, masonry, and basic electrical work if illuminated. Essential understanding of code compliance and local permitting processes is necessary. Professional consultation or installation for electrical and structural elements is recommended for safety and compliance.)
A brick monument sign project involves foundational work, masonry, and potentially simple electrical, but lacks complex structural systems, extensive plumbing, or HVAC typical of residential buildings. Adherence to DuPage County's specific frost depth and local zoning requirements are key considerations, making it a relatively straightforward undertaking.
