Renovating a Home in Laval: What Homeowners Should Know Before Starting

Updated October 2026

Renovating a home in Laval can mean anything from updating a kitchen or bathroom to redesigning an entire floor, finishing a basement or planning the interior of a new construction.

Through its residential interior design projects in Laval, MK Imperium regularly encounters the same questions from homeowners: Do I need a permit? Can I remove a wall? Should I hire an interior designer before a contractor? And can AI now help design my renovation?

Here are some of the most important things to know before starting.

Do You Need a Permit to Renovate a Home in Laval?

Not every interior renovation in Laval requires a permit.

According to the City of Laval, renovating an existing kitchen or bathroom generally does not require a permit. However, requirements can change when work affects the structure of the home or modifies the dimensions or number of rooms. Adding a new bathroom can also require a permit.

At MK Imperium, this is why the early design stage looks beyond finishes. A project that begins with new kitchen cabinetry, for example, can evolve into a larger renovation involving circulation, adjoining rooms, lighting, millwork or structural changes.

The scope of the project matters more than simply calling it a “kitchen renovation” or “bathroom renovation.”

Can You Remove a Wall in a Laval Home?

Potentially, but removing a wall should never be treated as simply a design decision.

When work affects the structure or changes the configuration of rooms, municipal and technical requirements may apply. Depending on the work, professional structural documentation may also be necessary.

In MK Imperium's Laval projects, proposed layouts are developed around the actual conditions of the property. A rendering can show how beautiful an open-concept kitchen might look, but it cannot establish by itself whether a particular wall can be removed.

That is the difference between visualizing a renovation and developing a design that can actually be built.

What About Basements and Staircases?

Basement renovations can also trigger permit requirements when the project modifies the structure or configuration of rooms. Interior staircase modifications may also be subject to municipal requirements.

For MK Imperium, basement design is an opportunity to think beyond simply finishing unused square footage. A basement can become a family room, gym, office, entertainment space, bar or guest area that feels connected to the rest of the home.

When those ideas involve significant changes to the existing layout, however, municipal and technical considerations should become part of the planning process.

Should You Hire an Interior Designer Before a Contractor?

For a substantial renovation, developing the design before obtaining final construction pricing can make contractor estimates considerably more meaningful.

A contractor needs to understand what is actually being built. Custom millwork, natural stone, lighting, plumbing changes and structural modifications can dramatically affect the scope and price of a project.

MK Imperium's interior design process in Laval can include space planning, kitchen and bathroom design, material selections, custom millwork, visualization and technical development.

Defining these elements early helps transform an idea into a project that can be more accurately evaluated and priced.

When Should a Designer Get Involved in a Laval New Construction?

Ideally, early.

Kitchen layouts influence lighting and electrical locations. Bathrooms affect plumbing. Custom millwork interacts with walls and ceilings. Furniture planning can even influence electrical and lighting decisions.

Through its work on residential and new-construction interiors in Laval, MK Imperium approaches these decisions as interconnected parts of the same home.

Interior design for a new construction should therefore begin well before furniture selection.

Can AI Design Your Laval Home?

AI can be extremely useful for exploring styles, materials, layouts and different design possibilities.

MK Imperium sees AI and visualization as useful tools for communicating ideas, but an AI-generated image is not automatically a buildable design.

AI cannot confirm from an image whether a wall is structural, whether plumbing can practically be relocated, whether cabinetry dimensions work or whether a proposed renovation satisfies Laval's municipal requirements.

AI can help visualize what your home could become. Interior design determines how that vision can work in your actual home.

Planning a Renovation or New Construction in Laval?

A successful renovation starts before demolition.

Understanding the existing home, establishing priorities, developing the layout and identifying technical or municipal requirements early can help homeowners make better decisions before construction begins.

At MK Imperium, our approach to interior design in Laval connects the creative side of design with the practical realities of renovating or building a home. The goal is not simply to create an attractive concept, but to develop an interior that functions well, feels cohesive and can ultimately become a real space.

Whether you are planning a kitchen, bathroom, complete home renovation or new construction, thoughtful design can help bridge the gap between inspiration and execution.
