A kitchen budget is more reliable when each scope has a quantity, selection level, responsibility, and contingency—not one national price-per-square-foot claim.
Define scope before price
Separate cosmetic replacement from layout changes. Moving sinks, ranges, walls, windows, or electrical service can introduce design, permit, structural, plumbing, ventilation, and patching work. Write what stays, what moves, and who supplies each item.
Count cabinets by the actual layout, measure countertop surface and edge conditions, list appliances, and identify finish selections. Allowances should name both quantity and quality level.
Build the line items
Include design, permits, protection, temporary facilities, demolition, disposal, framing, drywall, paint, cabinets, hardware, counters, backsplash, flooring, plumbing, electrical, lighting, ventilation, appliances, trim, cleaning, delivery, tax, and project management where applicable.
Record whether labor includes installation only or also site preparation and repair. Compare proposals using the same scope table.
Use contingency correctly
A contingency is for unknown conditions and documented changes, not for knowingly omitted scope. Older homes and major layout changes usually carry more uncertainty. Keep the reserve controlled by the owner and require written changes that explain cost and schedule impact.
