Interior Designer vs Interior Decorator vs Design Consultant: What’s the Difference?

Planning a home update but not sure who to hire? When you start searching for an interior designer versus interior decorator, you’ll also come across design consultants. While these titles may sound similar, they offer different services, and choosing the wrong one can lead to unnecessary costs or delays.

In this guide, we’ll explain the differences between an interior designer, an interior decorator, and a design consultant. You’ll learn what each professional does, when to hire them, what they typically charge in Canada, and how to choose the right option for your project.

Quick Glance: The Three Roles Side by Side

The details below are where hiring mistakes actually happen, so don’t stop at the table.

What an Interior Designer Actually Does

An interior designer plans how your space functions, not just how it looks. If your project changes the layout of your home, you’ll likely need an interior designer rather than a decorator. They create layouts for walls, doorways, kitchens, and bathrooms. They prepare technical drawings, choose materials, coordinate with contractors and architects, and make sure the design meets building code requirements.

A simple way to tell if you need an interior designer is to ask whether your contractor will need drawings to complete the work. Common projects include:

• Removing a wall between your kitchen and dining room
• Reconfiguring your kitchen or bathroom
• Finishing your basement, including a legal secondary suite
• Planning the interior layout of your new home or a major addition

How Interior Designers Are Regulated in Canada

Interior design is a regulated profession in several provinces, including Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, and Nova Scotia.

If you’re hiring an interior designer in Ontario, check whether they are a member of ARIDO. Only ARIDO members can legally use the title Registered Interior Designer. Most have also passed the NCIDQ exam, which covers building codes, construction, building systems, and life safety.

Anyone can call themselves an interior decorator, but not everyone can legally use the title Registered Interior Designer. Checking a designer’s credentials before you hire can help you choose someone with the right qualifications.

What Designers Cost

Fees vary by city, project size, and the designer’s experience, so use these as general estimates rather than fixed prices.

• Hourly: Typically $100 to $300 per hour in major Canadian cities. Senior designers in Toronto and Vancouver often charge more.
• Percentage of the project budget: Usually 10% to 25% for full home renovations.
• Flat fee: A full service design package for a major kitchen renovation typically ranges from $5,000 to $20,000, excluding construction costs.

While hiring an interior designer adds to your upfront costs, it can help you avoid expensive design changes and construction delays later in the project.

What an Interior Decorator Actually Does

A decorator works with the space you already have. They do not make structural changes or alter the layout of your home. Instead, they help you choose colors, furniture, lighting, rugs, window treatments, artwork, and accessories to create a cohesive look.

A decorator can also help you avoid costly mistakes. Choosing the right furniture, finishes, and décor the first time can save you from replacing items later. Many decorators also have trade accounts with suppliers, which may give you access to exclusive furniture collections and better pricing.

When a Decorator Is the Right Choice

A decorator is a good fit if the layout of your home works, but you want to improve its appearance. Common projects include:

• Furnishing a new home after you move in
• Refreshing a dated living room without renovating
• Creating a consistent look across different rooms
• Staging your home before selling

Decorator fees typically range from $50 to $150 per hour. Many also offer flat rate packages for individual rooms. A single room refresh often costs $500 to $2,000 in design fees, excluding furniture and décor. Prices vary by location and experience, so it’s always worth requesting a detailed quote before you hire.

What a Design Consultant Actually Does

A design consultant provides expert advice without managing the project. You share your goals, and they help you make informed design decisions that you can carry out yourself. Consultations usually take place over one to three meetings, either in your home or online.

By the end of the consultation, you’ll typically receive:

• A written summary of recommendations
• A color palette or paint selection
• A furniture layout
• A shopping list with suggested products and retailers

This option is ideal if you’re comfortable handling the shopping and installation yourself but want professional guidance before you begin.

What a Design Consultation Includes

A consultation gives you a clear plan, but the implementation is up to you. The consultant does not purchase furniture, coordinate contractors, or oversee the installation. If you prefer someone to manage the project from start to finish, hiring a decorator or interior designer may be a better choice.

Design consultations typically cost $150 to $600 for a one- to two-hour session. Virtual consultations are often available at the lower end of that range. Many interior designers and decorators offer consultations as an affordable way for you to experience their services before committing to a larger project.

Choose the Right Professional for Your Project

The best choice depends on the type of work you want to do, not the job title.

Hire an Interior Designer If:

Choose an interior designer if your project changes the structure or layout of your home. Common examples include:

• Renovating a kitchen or bathroom
• Removing or adding walls
• Finishing a basement or building an addition
• Planning the interior of a new home
• Completing accessibility renovations that must meet building code requirements

If your project requires permits or construction drawings, an interior designer is usually the right choice.

Hire an Interior Decorator If:

Choose an interior decorator if the layout of your home already works and you want to improve its appearance. Common projects include:

• Furnishing a new home
• Refreshing outdated rooms
• Choosing paint colors, furniture, lighting, and window treatments
• Staging a home before selling

If your goal is to improve the look and feel of your space without renovating, a decorator is likely the best fit.

Hire a Design Consultant If:

A design consultant is a good option if you plan to manage the project yourself but want professional advice before getting started. They are well suited for:

• Small budgets or single room projects
• Choosing paint colors and finishes
• DIY home improvement projects
• Deciding what type of design help your project requires

A consultation can also help you determine whether your project needs a decorator, an interior designer, or simply a few design changes before you invest in a larger project.

Questions to Ask Before You Hire

No matter which professional you choose, asking the right questions can help you make an informed decision. Before you sign a contract, consider asking:

• Are you registered with a provincial association such as ARIDO, IDIBC, or IDA, or are you NCIDQ certified? This is especially important if your project involves renovations.
• Can you show me projects that are similar in size and budget to mine?
• How do you charge, and what services are included in your fee?
• How do you handle trade discounts? Are they passed on to clients, shared, or retained?
• Who will coordinate contractors and trades throughout the project?
• What happens if materials arrive damaged or the project is delayed?

Clear and detailed answers to these questions can help you understand what to expect before work begins.

Keep in mind that licensing requirements, permit rules, and renovation regulations vary by province. Before starting a major project, check the requirements in your area and discuss any project-specific questions with a qualified professional.

Frequently Asked Questions

What is the difference between an interior designer and an interior decorator?

A designer works on the structure and layout of a space, including renovations, technical drawings, and building code. A decorator works within an existing space, handling furniture, color, and styling. In Canada, designers are regulated in several provinces, while decorating is unregulated.

Is interior design a regulated profession in Canada?

In several provinces, yes. Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, and Nova Scotia all have provincial associations, and titles like "registered interior designer" are protected in some of them. Requirements vary by province, so check your provincial association’s directory.

How much does an interior designer cost in Canada?

Most charge $100 to $300 per hour, or 10 to 25 percent of the total project budget for full-service work. Rates are higher in Toronto and Vancouver and vary with experience, so get two or three quotes for your specific project.

How much does an interior decorator cost per room?

Flat per-room fees commonly run $500 to $2,000, not including the furniture and materials you buy. Hourly decorators typically charge $50 to $150. Trade discounts on furnishings can offset part of the fee.

Can an interior decorator do renovations?

No. Decorators don’t produce technical drawings, pull permits, or manage structural work. If your project involves moving walls, plumbing, or electrical, you need an interior designer working alongside licensed trades.

Do I need an interior designer for a small renovation?

For anything requiring a permit or affecting layout, plumbing, or electrical, yes, it’s worth it. For cosmetic updates like flooring, paint, and fixtures in the same locations, a decorator or a one-off design consultation may be enough.

What does a design consultation include?

Typically one to two hours in your home or online, where the professional reviews your space and goals, then gives direction on layout, color, and purchases. Many include a short written summary. You carry out the plan yourself.

How do I verify an interior designer’s credentials in Canada?

Check your provincial association’s public member directory, such as ARIDO in Ontario or IDIBC in British Columbia, and ask whether the designer holds NCIDQ certification. Legitimate designers expect the question.

Is it cheaper to hire a decorator or do it myself?

DIY is cheaper upfront, but decorators often recover part of their fee through trade discounts and by preventing costly wrong purchases. If you’re confident in your choices, DIY works. If you’ve made expensive furniture mistakes before, a decorator usually pays for herself.

Should I hire a designer or a decorator to sell my house?

A decorator, usually one who offers staging. Staging works with your existing layout to make the home show well, which is a decorating job. Only consider a designer if a broken layout or unfinished space is actively hurting your sale price.
