Signed and Sealed Plans

Signed and sealed plans are professional design documents bearing the responsible licensed professional's authentication in the required form. Their identity, scope and revision matter; a seal is not a general warranty for unrelated work.

Read the document identity

Keep the project address or applicability information, drawing title, revision and relevant design notes together. A partial screenshot can omit limitations or attachments. Ask which sheets govern the proposed work and how changes are documented. Do not treat a generic sample drawing, an old permit set or an image of a seal as evidence that the current proposal has been reviewed.

The installed work must relate to the documents

Field dimensions, materials and connections should correspond to the governing details. If site conditions differ, the project team needs a process for resolving the difference. A contractor's invoice and a product brochure serve different purposes from professional plans. Retain the completed document set with permit and inspection records for future work.

A practical homeowner example

A homeowner receives one structural sheet with a proposal. The contractor identifies the complete applicable set and explains which revisions will govern if dimensions change before construction.

Questions to bring to an estimate

  • Keep the document title, applicable version and project identification together.
  • Ask who determines the criteria or approval basis for this particular scope.
  • Retain the governing documents and written resolutions of changes.

Frequently asked question

Does a seal approve every future alteration?

No. Professional documents have an identified scope and basis. Later alterations must be evaluated for their own applicability and requirements.
