*We will beat lower prices advertised by other plans brokerage web sites. If, prior to purchasing a set of plans¹ from us, you find the same product advertised at a lower price, we will gladly discount the purchase price of the plans¹ by 5% of the LOWEST PRICE available for that plan package.

Once our staff is able to verify that the exact same plan is offered at a lower published price, is in stock and available for immediate sale and delivery from a competitor's website. Houseplans.com will offer the plan for sale at the lower published price less 5% for immediate purchase at that time only.

The advertised item must be the same plan as the product being purchased, including set type (5-copy, 8-copy, Reproducible, or CAD Set), foundation options, and any miscellaneous details. Advertised prices must be in the same currency that the original product was purchased in. Our Price Guarantee does not apply to advertising errors or misprints, special prices, restricted offers, mail order offers, rebates, coupons, premiums, free or bonus offers, OEM products, limited or minimum quantity or limited time offers, close-outs, liquidations, clearances, and special financing offers.

¹Full sets of plans only, such as 5-copy, 8-copy, Reproducible, or CAD, are eligible for this offer. 1-copy Sets, Study Sets, Additional Sets, Materials Lists, returns, and any purchase where the payment is defaulted at any time after the purchase are not eligible for this offer.

Please note that in most areas of the country, these house plans will be everything you need to build, but not necessarily everything you need to obtain a building permit.

In addition to the house plans you order, you may also need a site plan that shows where the house is going to be located on the property. You might also need beams sized to accommodate roof loads specific to your region. Your home builder can usually help you with this. You may also need a septic design unless your lot is served by a sanitary sewer system. Many areas now have area-specific energy codes that also have to be followed. This normally involves filling out a simple form providing documentation that your house plans are in compliance.

In some regions, there is a second step you will need to take to insure your house plans are in compliance with local codes. Some areas of North America have very strict engineering requirements. Examples of this would be earthquake-prone areas of California and the Pacific Coast, hurricane risk areas of the Florida, Gulf & Carolina Coasts. New York, New Jersey, Nevada, and parts of Illinois require review by a local professional as well. If you are building in these areas, it is most likely you will need to hire a state licensed structural engineer to analyze the design and provide additional drawings and calculations required by your building department. If you aren’t sure, building departments typically have a handout they will give you listing all of the items they require to submit for and obtain a building permit.

Additionally, stock plans do not have a professional stamp attached. If your building department requires one, they will only accept a stamp from a professional licensed in the state where you plan to build. In this case, you will need to take your house plans to a local engineer or architect for review and stamping. In addition, plans which are used to construct homes in Nevada are required to be drawn by a licensed Nevada architect.
