The Short Answer
A full kitchen remodel in Troy requires a building permit if you're moving walls, relocating plumbing fixtures, adding electrical circuits, modifying gas lines, installing a range hood with exterior ducting, or changing window/door openings. Cosmetic-only work (cabinets, countertops, appliance replacement) does not.
Troy's Building Department treats kitchen remodels more strictly than some neighboring Ohio municipalities because the city requires separate sub-permits (building, plumbing, electrical) to be pulled together under one master application, with a pre-submittal conference recommended for projects over $5,000 in valuation. This is different from Dayton or Springdale, where you can sometimes file electrical and plumbing independently after the building permit is issued. Troy also enforces the 2017 International Building Code with Ohio amendments, which means load-bearing wall removal requires an engineer's letter AND a full structural plan — not just a builder's affidavit. The city's online portal (accessible via Troy's municipal website) allows e-filing but plan review is still sequential (building first, then electrical and plumbing in parallel), typically taking 3–6 weeks. If your home was built before 1978, lead-paint disclosure is mandatory before any work begins. The frost depth in Troy is 32 inches; if you're relocating a plumbing vent stack, it must be cleared above the roof by at least 12 inches (IRC R802.4), which affects the rough-in roughing details the plumber must show on the permit drawing.

What happens if you skip the permit (and you needed one)

Troy kitchen remodel permits — the key details

Troy's Building Department requires three separate permit applications (building, plumbing, electrical) for any kitchen remodel that includes wall relocation, plumbing fixture movement, or new electrical circuits. You can file all three together online via the city's permit portal or in person at Troy City Hall (114 S. Market Street). The building permit is the parent permit; plumbing and electrical are sub-permits issued after the building permit is approved in plan review. Per IRC E3702, kitchens require a minimum of two small-appliance branch circuits (20-amp, 12 AWG minimum), each serving only kitchen countertop receptacles; these must be shown on the electrical plan with exact location and separation (no receptacle more than 48 inches from another per IRC E3801). If you're adding a range hood with exterior ducting, the rough framing must show the duct path, exterior termination cap detail, and clearance from soffit/fascia; many Troy plan reviewers reject hoods without a detail drawing showing damper and cap type. Load-bearing wall removal is the highest-risk category: Troy enforces a strict rule that any wall removal on the first or second floor requires a structural engineer's sealed letter AND a full beam-sizing calculation (no exceptions for owner-builders). The cost for an engineer's letter is typically $800–$1,200; this is not optional and must be submitted with the building permit application. Plumbing relocation must show trap arm distance (2 feet maximum from trap to vent per IRC P3108), vent rise clearance (6 feet above fixture crown weir minimum per IRC P3105), and the existing trap location; if you're moving a sink 10+ feet, the plumber often needs to relocate the vent stack or add a new one, which adds $1,500–$3,000 to the project. Gas line modifications (moving a range, adding a gas cooktop, or extending a gas line) require a separate mechanical permit and a pressure test (per NEC 8.2 and Ohio's mechanical code); many homeowners forget this and it causes plan-review delays.
