Plumber's Affidavit of Completed Work

What a good one includes

• It must feature your full legal name, business name, and active state or municipal plumbing license number.
• It must clearly identify the physical address and specific location within the building where the plumbing work was performed.
• It should include a detailed description of the exact plumbing installations, alterations, or repairs completed.
• It needs an explicit statement certifying that all work complies with the applicable local, state, or national plumbing codes.
• It must reference the specific building or plumbing permit numbers associated with the project.
• It requires a standard notary public acknowledgment block to verify your signature under oath.

Common mistakes to avoid

• Leaving the description of work too vague or general can cause municipal inspectors to reject the affidavit entirely.
• Forgetting to verify that the license number and expiration date listed on the document are completely active and accurate will invalidate the filing.
• Signing the affidavit before you are physically in front of a licensed notary public prevents legal notarization and requires a reprint.
• Omitting the local building department's exact permit number often leads to administrative delays and lost paperwork.
