Structural Engineering questions, answered by experts

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.
