Structural engineering often comes up when a builder or local building department reviews what is needed for permit submission. In some cases, that may include structural calculations, added details, or stamped drawings from a licensed engineer.

Your Architectural Designs house plan provides the construction drawings that communicate the home’s design. Structural engineering serves a separate, site-specific role by reviewing the foundation, framing, roof, and other load-bearing elements for the conditions and requirements of your building location.

Because those requirements depend on the property and location, structural engineering is typically handled separately across the house plan industry.

When you purchase a house plan from Architectural Designs, you receive a set of construction drawings designed to help your builder understand the design, estimate costs, and begin planning the build.

A typical plan set may include:

Some plans also include building cross sections and electrical plans.

Because we work with nearly 200 architects and residential designers, the exact sheets and level of detail vary by plan. Before purchasing, review the What’s Included section on the individual plan page to see exactly what comes with that design.

Together, these drawings show the home’s layout, dimensions, exterior appearance, roofline, foundation, and key construction details. They give your builder, engineer, and other professionals a clear design to work from.

A stock house plan may be built in many different locations, but structural requirements vary by property and municipality. A coastal project may need to meet high-wind requirements, while the same design in a northern climate may need to account for heavier snow loads. Soil conditions, seismic activity, and local building codes can also affect the engineering needed for permitting.

That’s why stock plans do not typically include jurisdiction-specific structural engineering or a licensed engineer’s stamp. Once the plan and building site are identified, an engineer can review the drawings alongside available property information and local requirements.

Depending on the project, the engineer may review:

Based on that review, the engineer may provide structural calculations, updated details, and stamped drawings when required by the local building department.
