Tips
- Fee is charged as a percentage of standard ICC valuation, not a flat valuation-bracket table like new construction — level (1/2/3) depends on scope, and Level 3 (30%) applies once the work area exceeds half the building's area.
- A signed contractor-client contract identifying the value of work is the preferred fee basis; without one, PDSD assigns valuation itself using the ICC Valuation Table.
- Residential Addition/Alteration (Interior Only) has its own separate checklist from full exterior additions/alterations.
- Interior cosmetic work (paint, flooring, cabinets, countertops) needs no permit as long as plumbing/electrical are untouched.
