All exterior walls are load-bearing. To determine which of your interior walls are load-bearing, look at your home's original plans or hire a structural engineer to assess the structure. Non-load-bearing walls usually don't have any walls, posts, or other supports directly above or below them. In most homes, load-bearing walls include those that are directly above metal or multi-board wood beams in your basement, directly above or below known load-bearing walls or attic knee walls, or are perpendicular to your floor joists.

Homeowners without expertise in this area should not calculate load or size a beam. A structural engineer, either hired by you or on staff with your general contractor, can perform the calculations and make additional recommendations when necessary, like larger footings for support columns. An inspector will take a look at the site, issue a permit, and check the structure before the finishing work begins.

The average national cost to hire a structural engineer is about $500, but you may pay as little as $350 or as much as $800. Exact costs depend on the project. You should consult a licensed, experienced engineer for any job concerning the structure of your home, including building a new home or remodeling an existing one.

You must obtain a permit for the removal of a load-bearing wall. This requirement exists because the wall provides essential structural support and its removal affects your home’s stability. Local building codes demand permits and inspections to confirm that all alterations meet stringent safety regulations. Securing a permit guarantees that the project is executed safely and protects your investment by ensuring professional oversight and adherence to all applicable guidelines.

You must hire a licensed professional when removing a load-bearing wall. This project requires the expertise of a general contractor and a structural engineer to ensure that all structural adjustments and safety regulations are properly met. Relying on professionals guarantees compliance with building codes and preserves the stability of your home, as a DIY approach cannot safely account for complex structural modifications.
