Quick Answer
Do owner-builder and permit authorization forms need to be notarized?
Sometimes. Owner-builder affidavits and permit authorization forms are controlled by state law and the local building department. Some agencies require a notarized owner signature. Others require the owner to appear and sign before a permit technician. Some accept a notarized authorization letter when an agent pulls the permit.
Do not assume remote online notarization is acceptable merely because the form contains a notarial certificate. Confirm the building department’s current form, appearance requirement, identification rules, and electronic-submission policy before scheduling.
An owner who applies for a building permit without using a licensed general contractor may be acting under an owner-builder exemption. Because the owner assumes responsibilities normally handled by a licensed contractor, permitting agencies often require a disclosure statement or affidavit.
Other permit workflows use authorization documents when:
Common Permit Authorization Situations
Read the construction document notarization guide.
- An agent applies for a permit.
- A contractor acts for the owner.
- A permit runner submits documents.
- Property is held in a trust or business entity.
- A contractor changes during the project.
- A representative signs instead of the individual owner.
These forms are not standardized nationwide.
Owner-Builder Affidavit vs. Permit Authorization
| Document | General purpose |
|---|---|
| Owner-builder affidavit or disclosure | Confirms that the owner is applying under an owner-builder exemption and accepts specified responsibilities |
| Permit authorization form | Authorizes a contractor, agent, or representative to act in the permit process |
| Owner/contractor affidavit | Joint or separate statements required by the permitting agency |
| Agent authorization letter | Authorizes another person to submit, retrieve, or manage a permit |
| Trust authority affidavit | Explains authority to act for property held in a trust |
| Change-of-contractor affidavit | Documents a contractor change during an active permit |
The agency’s current form determines who signs, whether notarization is required, and whether personal appearance is mandatory.
Florida’s Owner-Builder Disclosure
Florida Statutes section 489.103 provides an owner-builder exemption under specified conditions.
The statute includes an owner disclosure statement explaining responsibilities associated with acting as one’s own contractor. Before a building permit can be issued, the disclosure must be completed and signed by the property owner and returned to the local permitting agency.
The statute does not create one universal electronic submission process for every county or municipality. Local agencies administer their permit procedures and may require a notarized affidavit, personal appearance, identification, proof of ownership, or other documentation.
Some Florida Agencies Require Notarization
The City of Greenacres explains that its Owner-Builder Affidavit and Disclosure Statement must be completed by the property owner, notarized, and submitted with the permit application.
The City of Clewiston’s Owner-Builder Affidavit and Disclosure Statement states that the owner must personally appear to sign the permit application and have the form notarized at the Building Department.
The Village of Key Biscayne publishes its own Owner-Builder Affidavit with project and owner responsibilities.
These procedures demonstrate that even within one state, local processes can differ.
Some Agencies Require Signing Before Staff
Pinellas County’s Owner/Contractor Affidavit procedure states that the form must be signed in front of a permit technician at the Building and Development Review Services office.
That requirement is different from ordinary notarization.
A remotely notarized affidavit should not be substituted when the agency requires an in-person signature before its employee. The applicant should contact the agency if attendance is not possible.
Permit Authorization Letters for Agents
A property owner may authorize another person to pull or manage a permit.
For example, a building department may require:
- A notarized owner authorization letter
- The owner’s identification
- The agent’s identification
- Proof of ownership
- A specific agency form
- Corporate or trust authority
- Contractor-license information
California’s City of Yucaipa states that when an authorized agent pulls a permit for an owner-builder, the City requires a notarized letter authorizing that person. Notarization confirms the owner’s signature; it does not determine whether the agent qualifies to perform construction work.
Trust and Entity Ownership
Property may be titled in:
- A trust
- LLC
- Corporation
- Partnership
- Estate
- Other legal entity
The building department may require separate proof of authority. Collier County, Florida, for example, provides owner-builder guidance for property held in trust and requires an Affidavit of Authority Under Trust to be signed, witnessed, and notarized before submission. A notary does not determine who has authority under a trust, operating agreement, corporate resolution, or probate document.
What the Notary Does
When notarization is permitted, the notary may:
Verify the signer’s identity.
Confirm personal appearance.
Take an acknowledgment or administer an oath.
Witness the signature.
Complete the notarial certificate.
Create the required notarial record.
The notary does not:
Issue the permit.
Verify property ownership.
Approve the owner-builder exemption.
Confirm contractor licensing.
Approve plans.
Determine zoning compliance.
Appoint an agent.
Determine trust or corporate authority.
Waive a personal-appearance requirement.
Can These Forms Be Notarized Online?
Potentially—but building-department acceptance must be confirmed first.
- The form contains an authorized notarial act.
- State law permits RON for that act.
- The local agency accepts remote notarization.
- Personal appearance before agency staff is not required.
- Electronic submission is permitted.
- The signer and representative-capacity wording are correct.
RON is not appropriate when the agency requires the owner to sign before a permit technician or personally appear at the building department.
Does Your Permit Form Allow Remote Notarization?
Confirm the building department’s current form, signer, appearance rules, identification requirements, and RON acceptance before requesting an online session.
Request Permit-Form NotarizationPreparation Checklist
Prepare:
Do not sign before the session if the notary must witness the signature or administer an oath.
- The current building-department form.
- The permit number, if assigned.
- Property address and parcel information.
- Proof of ownership requested by the agency.
- The owner’s exact name.
- Agent or contractor information.
- Trust or business authority documents if required.
- The required notarial certificate.
- Agency submission instructions.
- Confirmation that RON is accepted.

Key Takeaway
Owner-builder and permit authorization requirements are local.
Some agencies require notarization. Others require personal appearance before permitting staff. An authorization letter may be notarized even when the main permit application follows a different procedure.
Always confirm the current building-department requirements before scheduling RON.
Frequently asked questions
Can an owner-builder affidavit be notarized online?
Possibly, but only if the agency accepts RON and does not require personal appearance before a permit technician or building official.
Can someone else pull an owner-builder permit?
The building department determines whether an agent may act for the owner and what authorization is required. Some agencies request a notarized authorization letter.
Does notarization prove that I own the property?
No. The building department separately determines whether the applicant has the required ownership interest or authority. A notary identifies the signer and completes the notarial act shown on the document. Notarization does not establish title, resolve ownership disputes, or verify that the signer qualifies for an owner-builder exemption.
Can an agent sign an owner-builder affidavit for the property owner?
Do not assume so. Some owner-builder exemptions require the owner to appear personally, sign the permit application, accept direct responsibility for the work, or satisfy other local conditions. An agent may be able to sign a separate permit authorization or act for certain entities, trusts, or owners when the permitting authority accepts that arrangement, but an agent’s authority does not automatically convert the agent into the qualifying owner-builder. Ask the building department which document and signing procedure it requires.
Can an owner-builder or permit authorization form be notarized online?
Potentially, when the required notarial act is permitted under the law governing the notary and the receiving building department accepts a remotely notarized document. Local procedures matter. A department may require an in-person appearance before permit personnel, use its own electronic verification system, require original supporting documents, or impose a specific submission method. Confirm acceptance with the permitting authority before scheduling remote online notarization.
What should I prepare for the notarization?
Prepare the final, unsigned form; acceptable identification; the property address and parcel information requested by the form; the permit or application number, if one has been assigned; and any ownership, trust, entity, or authorization documents the building department requires. Confirm the correct signer, notarial certificate, witness requirements, and submission procedure before the session. Do not leave required factual statements blank for the notary to complete.
