Legal Basements

A legal basement involves considerably more than simply finishing the interior of a basement. Depending on the property and intended use, the project may involve permits, egress, structural openings, fire separation, stairs, drainage, lighting and inspections.

Mahal can support legal basement projects through the construction process, from assessing the existing space and planning the required work to construction, inspections and final handover.

The goal is to help property owners develop a functional basement apartment while addressing the applicable construction and safety requirements.

For larger basement projects, Mahal provides construction services that go beyond interior finishing. We can manage the structural and construction requirements involved in developing your basement, including framing, stairs, bathrooms, entrances, drainage and other project components.

Every basement has different conditions and requirements. Our process starts by understanding the property and project scope, then planning the work required to take your basement from its existing condition to a completed, functional space.

Mahal can help with different entrance configurations, including side entrances, below-grade stairwells and full walkout solutions, depending on the property and site conditions.

Basement entrance projects can involve more than installing a door. Structural openings, stairs, excavation, drainage, grading, waterproofing and safety requirements may all need to be considered. Mahal coordinates these construction requirements as part of the overall project.

Whether you’re looking to refresh an outdated basement or completely transform an unfinished space, Mahal provides comprehensive basement renovation services tailored to your property.

From layout changes and framing to flooring, bathrooms, painting and finishing, we can help turn your basement into a comfortable, functional part of your home.

An unfinished basement is an opportunity to create additional usable space in your home. Mahal provides professional basement finishing services to help transform unfinished areas into comfortable living, recreational, rental or functional spaces.

From framing and drywall to flooring, lighting, bathrooms and final finishes, we can coordinate the different stages of your basement finishing project. Our goal is to create a finished basement that is practical, well-planned and built around how you intend to use the space.

Developing a basement into an apartment can create valuable additional living or rental space. Mahal provides basement construction and renovation services for property owners looking to develop functional basement apartments, from the initial construction requirements through the finishing stages.

Depending on the project, this can include framing, bathrooms, stairs, separate entrances, drainage and other elements required to create a practical living space. We can help coordinate the different components of the project so you have one team managing the construction work.
