What is not included in a typical set of stock plans?

1. Architectural and Engineering Seals / Stamps

Due to variances in local building codes and requirements, local structural engineering is almost always required. Foundation details, truss calculations, and load calculations must be performed by a local engineer to meet location-specific codes and requirements. Fortunately, in most cases, the truss company you will be using to purchase lumber materials can engineer your trusses, and a local structural engineer can typically provide the remaining calcs and details in a few weeks.

2. Site Plans and Surveys

Property surveys and site plans showing the location of the house on the property are not included in a typical set of stock plans. TheHousePlanSite.com can provide site plans upon request - fees are quoted on an individual basis. Free Site Plan Estimate >

3. Mechanical Schematics & Electrical Load Calculations

Some municipalities require mechanical and electrical schematics while others do not. Actual locations of HVAC ducting and vents, plumbing pipe and septic/sewer locations and connections, gas line schematics and electrical wiring and panel diagrams must be drawn to location-specific standards. In many cases, the contractor or sub-contractor you will be using to install your electrical and mechanical systems can provide this information if required.

When comparing pricing on stock plans vs. custom plans, keep in mind that custom plans may also require engineering as well, and may or may not include the other items listed above.
