Your Drafter Drew It - but the Permit Office Wants an Engineer
It is one of the most common permit problems in the country. A homeowner or contractor hires a drafting service or buys stock plans, submits them, and the building department responds: “Provide drawings sealed by a licensed engineer.” Many drafting services state clearly that they are not engineers and that stamps are not included – leaving you to find one on your own.
SitePlaners exists to close that gap. We take drawings from any source, complete the engineering and seal them, so your permit moves forward with one quick step instead of a new search.
Send Us These for the Fastest Quote:

Your Questions About Getting Plans Stamped, Answered
Can an engineer stamp plans that someone else drew?
Yes, after reviewing them and taking responsible charge of the design. That typically includes calculations and any revisions needed for code compliance. Sealing plans without review is prohibited by state licensing boards – and we never do it.
How do I get my plans stamped by an engineer online?
Upload your plans and project address through our quote form or share them in live chat. We reply with a price and delivery date in 5-10 minutes, review and engineer the plans, and deliver sealed PDFs (or wet-stamped sets if required).
Can you stamp stock or purchased house plans?
Yes. Stock plans are usually sold unsealed and are not engineered for your specific site and local code. We review and adapt them as needed and seal them for your state.
Will my plans need to be changed?
Sometimes. If a beam, connection or foundation does not meet code, we specify the correction. Most sets need targeted changes rather than a full redraw.
Does the engineer need to be licensed in my state?
Yes. Seals are only valid in states where the engineer is licensed, and we assign your project accordingly.
How much does it cost to get plans stamped?
It depends on the size and type of plans and how much engineering is required. Send your drawings for a fixed quote – we reply in 5-10 minutes.
