What to Include in Your Submission

- Application forms, owner/tenant information, and contractor license details Code analysis summary: occupancy classification, construction type, occupant load, fire-resistance ratings, egress paths Architectural drawings: floor plans, reflected ceiling plans, finish schedules, door hardware, details, and dimensions MEP plans: mechanical ventilation and ductwork, electrical power/lighting, panel schedules, plumbing risers and fixture counts Fire protection: sprinkler head layout and calculations (if applicable), fire alarm device locations, hood suppression systems Structural sheets: if modifying load-bearing elements or adding equipment/mezzanines Accessibility narrative: entrances, routes, restrooms, counters, hardware per ADA compliance construction requirements Energy code compliance: lighting power density, controls, envelope changes, and mechanical performance Equipment cut sheets: kitchen equipment, RTUs, grease interceptors, specialty devices Site plan: for exterior work, signage, or parking adjustments Special inspections statement, if required

ADA compliance construction is non-negotiable. MEP coordination gaps: Avoid clashes between ductwork, sprinkler piping, lights, and ceiling heights. Coordinated overlay drawings help. Fire protection deferrals: If allowed, note any deferred submittals, but include enough information for life safety review. Kitchen and grease management: For food uses, provide hood types, makeup air, duct routing, and grease interceptor sizing. Energy code documentation: Lighting controls, ventilation rates, economizers, and envelope changes must be documented.
