The correct permit type depends on the existing building and the proposed scope of work.
A renovation permit is generally appropriate when modifying, repairing, or improving an existing structure while retaining the portions necessary to qualify as an alteration under applicable codes.
A new construction permit is required when building a completely new structure or when the project qualifies as new construction under local regulations.
Renovation permits may involve fewer requirements for limited projects, but extensive renovations can require substantial structural upgrades and additional code compliance. The permit classification must reflect the actual work rather than simply choosing the faster or less expensive option.
