The value is not just choosing finishes. It is turning how the space needs to work into coordinated layouts, interior drawings and design decisions the broader project team can use.

How should people move through the space?
Where do rooms, counters, storage and furniture need to go?
Which interior elements affect accessibility or other project requirements?
What finishes, millwork and interior details need to be documented?
Which decisions need coordination with architects, engineers or permit professionals?

Hiring an Interior Designer? Start Here.

Does Permit.ca provide interior design services directly?

No. Permit.ca is a network that connects clients with independent interior designers and other design and building professionals. Permit.ca does not directly provide interior design, architectural, engineering or other regulated professional services.

What does an interior designer do on a building project?

An interior designer may develop interior layouts, space planning, finish selections, millwork concepts, reflected ceiling plans, accessibility-related interior coordination and other interior documentation within the agreed scope.

Can an interior designer prepare drawings for a building permit?

Depending on the project, jurisdiction and the designer's qualifications, an interior designer may prepare or coordinate certain interior design drawings. Confirm which permit-related drawings and professional responsibilities are included in the quote and who is authorized to prepare or take responsibility for them.

Do I need an interior designer or an architect?

That depends on the building, project scope and applicable professional requirements. An interior designer may focus on the interior layout and finishes, while an architect or other qualified professional may be required for broader building design or regulated work.

Can an interior designer help with a commercial fit-out?

Yes. An interior designer may develop the space plan, interior drawings, finish schedules, millwork and project-team coordination within the agreed scope.

Can an interior designer coordinate accessibility requirements?

An interior designer can coordinate interior layouts and dimensions with applicable accessibility requirements within their scope, while specialized code review or other professional input may also be required depending on the project.

What drawings might an interior designer prepare?

Depending on the scope and qualifications, deliverables may include space plans, interior elevations, millwork details, finish plans, finish schedules and reflected ceiling coordination. Confirm the exact drawing set in the quote.

Can an interior designer coordinate with engineers?

Yes. Interior layouts may need coordination with mechanical, electrical, structural and other building systems. Confirm which coordination meetings, revisions and consultant inputs are included in the scope.

What should I compare in interior designer quotes?

Compare the design scope, drawing deliverables, finish selections, number of revisions, consultant coordination, meetings, timeline, milestones and total fee.

Does an interior designer guarantee permit approval?

No. Interior design work can support the design and permit process, but the applicable authority decides whether a building permit or other approval is issued.
