A permit drawing set needs to do more than show the proposed floor plan. The drawings should clearly distinguish existing conditions from proposed work and remain coordinated across plans, elevations, sections, details, schedules, and consultant documents.
One common source of avoidable permit comments is information that does not agree from sheet to sheet—for example, dimensions that change between plans and elevations, structural information that does not match the architectural layout, or zoning information that does not reflect the final design.
The level of detail also depends on the project. A simple renovation may need only a focused set of drawings, while additions, structural alterations, commercial work, or changes of use may require additional code information and consultant coordination. A contractor sketch can be useful for communicating an idea, but it may not provide enough coordinated information for municipal permit review.
