Interior Design Cost in Montreal (2026)
Quick Answer
Estimated rangeIn Montreal, interior design is commonly priced either by the hour, as a flat fee for a room or project phase, or as a percentage of renovation/furnishing spend. A practical market estimate is around CAD 100-250 per hour for design services, with small room design work often landing around CAD 1,500-5,000 and full-home or renovation-related design fees running much higher depending on scope. Exact prices vary widely because interior design is not a one-price trade service and many firms quote only after consultation.
Overview
Interior design costs in Montreal depend mostly on the level of service you need: a one-off consultation, design-only plans, room-by-room decorating, or full project management tied to renovations and furniture procurement. In practice, many Montreal designers and design studios charge by the hour for advice and concept work, then move to fixed-fee or percentage-based pricing for larger projects. Compared with purely decorative help, projects involving kitchen or bathroom redesign, custom millwork, contractor coordination or permit-related drawing work usually cost significantly more. For budgeting, homeowners in Montreal should expect a meaningful spread. Smaller jobs such as colour consultations, furniture layouts and sourcing are usually at the lower end, while full-apartment redesigns and renovation support can rise quickly once site visits, drawings, revisions and procurement are added. Local costs are also influenced by property type: older Montreal flats and heritage-style buildings can require more bespoke solutions, measurements and coordination. Québec sales taxes also apply to professional design services in most cases. Because publicly posted Montreal-specific pricing is limited, the figures below combine official regulatory context with clearly labelled market estimates designed to help you set a realistic starting budget before requesting quotes.

Professional fees are normally quoted in CAD and are usually subject to GST and QST in Quebec. Tipping is not standard for interior design services, though clients may choose to acknowledge exceptional service separately.

Frequently Asked Questions
Do interior designers in Montreal charge by the hour or by project?+
Both are common. Smaller advice-led jobs are often hourly, while larger residential projects are frequently quoted as fixed fees or as a percentage of the total project budget.
Is interior design regulated in Quebec?+
Interior design is represented professionally in Quebec by the APDIQ, but consumers should still check exactly what service is being offered. If work involves structural, architectural or permit-related matters, other licensed professionals may also be required.
What is the difference between interior design and interior decorating?+
Decorating usually focuses on finishes, furnishings and styling. Interior design can extend further into space planning, technical coordination, custom cabinetry and renovation-related decision-making, which usually increases the fee.
Does the design fee include furniture and renovation costs?+
Usually not. Design fees are commonly separate from construction, trades, furniture, lighting and materials, though some firms bundle procurement or charge a percentage on purchased items.
Are taxes included in Montreal interior design quotes?+
Quotes may be shown before tax. In Quebec, GST and QST generally apply to professional services, so confirm whether the quoted amount is tax-inclusive.
