Interior design in Gatineau: hiring and planning

Masters' Guild · Updated

For interior design in Gatineau, choose a designer by the work you need: furnishing advice, a room layout or renovation drawings and coordination. Ask for a written scope covering deliverables, fees, purchasing and permit responsibilities before you commit. If you plan to alter interior walls, Gatineau requires a building permit regardless of the project cost, so settle that responsibility before approving the layout. [1]

Choose the scope before choosing the designer

Start with a brief that names the room, the problem and what you want to keep. Describe awkward circulation, missing storage, furniture that must fit and activities that share the space. Attach photographs and a measured sketch. For a furnishing project, request a layout, a finish palette and a shopping list with dimensions. For a renovation, ask which drawings, specifications and site visits the designer will provide.

Québec describes interior-design work as including assessment of existing spaces, material selection, layout plans, technical drawings and collaboration with other professionals. Use that description to question candidates about your project. Ask to see a comparable completed drawing package, not just finished-room photographs, and have the designer identify any work they would refer to another professional. [3]

Compare fees and purchasing responsibilities

Request a proposal that separates design labour, drawings, revisions, site visits, purchasing and construction coordination. Ask whether the designer charges an hourly rate, a fixed fee or another arrangement, and request the rule for work beyond the agreed scope. Set an approval point before the designer proceeds from concepts to detailed drawings or orders.

Build a separate purchasing budget for furniture, lighting, finishes, delivery and installation. Ask who places orders, receives deliveries, checks damage and handles returns. Have the designer disclose purchasing charges and explain how they treat discounts. Before approving a custom item, confirm measurements, finish samples, cancellation terms and the person responsible for correcting an ordering error.

Agree on a schedule with distinct dates for your decisions, drawing approval, permit submission, ordering and installation. Gatineau says permit processing depends on the request type, workload and file complexity. Ask the designer to identify which parts of the schedule depend on municipal approval before you book construction. [1]

Check permit needs before approving a new layout

Gatineau’s FAQ says work on an existing building costing less than $26,000 in labour and materials before tax does not require a permit unless an exception applies. Those exceptions include work involving interior walls, foundations or structure, regardless of cost. Do not assume that a small budget or a non-load-bearing wall removes the permit requirement. [1]

Use the City’s URBAIN tool with the property address, lot number or property identifier to check the proposed work. The City describes its results as informational. URBAIN directs users to a formal application when a permit is necessary and to an information request for certain complex situations. Name the person responsible for preparing documents, submitting the application and answering municipal questions in your design agreement. [1]

Resolve basement access and lighting specifications

Before approving basement cabinetry or flooring, locate the backwater valves with the appropriate tradesperson. Gatineau requires homeowners to install backwater valves regardless of the home’s construction year and keep them accessible for maintenance. The City calls for an access panel where a valve sits within a wall or under the basement floor. Ask the designer to show that access on the layout before you approve finishes. [2]

Ask for a lighting schedule that names brightness in lumens and light colour in Kelvin. Natural Resources Canada explains that lumens measure brightness, while watts measure electricity use; lower Kelvin values indicate warmer, more yellow light. Review finish samples under your proposed lighting and specify the bulbs along with the fixtures. [4]

Local details that affect your job

A designer submitting your permit needs authorization

Gatineau allows only the owner or an authorized representative to submit an online application. A representative must attach a power of attorney. If your designer will apply for you, include that authorization and submission responsibility in the agreement. The City says some application fees pay for file review and may remain non-refundable if it refuses the permit. [1]

Basement finishes must preserve maintenance access

Gatineau says backwater valves must remain accessible at all times and calls for maintenance at least twice a year. For a basement design, ask for a drawing that marks each access panel and check that cabinetry and furniture placement leave it reachable. Resolve access before approving a continuous floor finish or built-in storage over that location. [2]

Your hiring checklist

  1. Prepare room photographs, a measured sketch and a list of furniture you want to keep.
  2. State your design-fee allowance and purchasing budget as separate amounts.
  3. Request sample deliverables from a project with a similar scope.
  4. Assign responsibility for checking permit requirements and preparing application documents.
  5. Ask the designer to mark service access points before you approve basement finishes.
  6. Confirm revision limits, purchasing charges and written approval rules for extra work.
  7. Record who checks deliveries, manages returns and approves substitutions.

Frequently Asked Questions

Does painting require a building permit?

Gatineau lists painting among work that does not require a building permit or authorization certificate. If your project also includes wall alterations or other renovation work, check the full scope rather than treating it all as decorating. The City says applicable standards still apply without a permit. [1]

Does every interior designer hold APDIQ certification?

Do not assume certification from the service description alone. Québec says APDIQ certification is required to hold the APDIQ Certified Interior Designer title. Ask candidates to identify their education and credentials, and substantiate any designation they use. [3]

Can the designer submit the permit application for me?

Yes, as your authorized representative. Gatineau requires a power of attorney with the application documents. Confirm that the designer’s fee includes submission and responses to municipal questions, or agree on separate charges. [1]

How should I specify replacement bulb brightness?

Use lumens. Natural Resources Canada’s reference lists 450 lumens for the brightness associated with a 40-watt incandescent bulb, 800 for 60 watts and 1,600 for 100 watts. These are bulb comparisons, not a calculation of how much light your room needs. [4]
