Is an electronic signature legally binding?

Yes. Under the federal ESIGN Act (15 U.S.C. §7001) and state UETA provisions, electronic signatures are legally enforceable when intent, consent, attribution, and record retention requirements are satisfied.

Do I need a notary for this agreement?

Not always. Notarization depends on the document type, state law, and whether the agreement will be recorded; deeds and certain conveyances commonly require notarization before recording.

Can I use remote online notarization (RON)?

Many states permit RON with identity proofing, audio-video recording, and retention requirements; confirm your state notary rules and preserve required recordings and journal entries.

What if names or entity details do not match title?

Mismatched names can delay recording and lender approval. Correct via identity affidavits, amend the agreement before recording, or obtain title counsel to resolve discrepancies.

How long should I keep the executed agreement?

Retain for the active term plus at least 3 years; IRS records require 3 years (IRC §6501(a)), many real estate matters recommend 7–10 years, and HIPAA rules require 6 years where applicable.

Are e-signed copies secure and admissible?

Properly managed e-signed PDFs with audit trails, timestamps, and secure storage are admissible. Platforms that use TLS, AES-256, SOC 2 controls, and maintain full audit logs support evidentiary value.

What a Real Estate Addition Agreement Covers

A Real Estate Addition Agreement is a legally binding contract that documents the terms, scope, and responsibilities related to adding square footage, rooms, or structures to an existing property. It identifies the property, owner(s), contractor or service provider, detailed description of the addition, estimated costs, timelines, permits, and responsibilities for inspections, utilities, and code compliance. The agreement also allocates risk by specifying warranties, insurance, payment schedule, change-order procedures, and dispute resolution. Use this document to reduce ambiguity, protect parties, and support permit or financing requirements when expanding real property.

Why this Agreement Matters for Additions

A Real Estate Addition Agreement clarifies responsibilities, protects investment, and documents cost allocation, permitting obligations, and timelines. It reduces dispute risk, supports contractor claims, and creates a record useful for permitting, inspections, lender review, and future resale disclosures.

01

Gather information: Collect plans, permits, and owner contact info.

Key Parties and Their Roles

Owner

The property owner or legal entity that commissions the addition, secures financing, provides access, and approves final work. The owner must confirm title status, disclose relevant property conditions, and satisfy payment obligations under the agreement to avoid lien claims.

Contractor

The licensed contractor or firm that performs the addition, manages subcontractors, maintains insurance, and complies with building codes. The contractor accepts the scope, schedule, change-order process, and indemnity terms as defined in the agreement.

Core Elements to Include in the Agreement

A professional Real Estate Addition Agreement covers all technical, financial, and legal aspects needed to manage the project, allocate risk, and satisfy permit and lender requirements.

Parties

Identify full legal names, entity types, roles, contact details, and authorized signatories for owner, contractor, architect, and any lender or title party; accuracy avoids disputes and ensures enforceability.

Scope

Provide a precise description of work, materials, plans, drawings, dimensions, and applicable building codes; attach exhibits and reference approved permit drawings to prevent later disagreements about deliverables.

Schedule

Set start and completion dates, milestone deadlines, inspection windows, and liquidated damages or extension procedures for weather or permit delays to align expectations and project management.

Payment

Specify total contract sum, installment schedule, retainage amount, conditions for release of retainage, acceptable payment methods, and remedies for late payment or nonpayment.

Permits & Approvals

Assign responsibility for obtaining permits, inspections, and code compliance; require copies of issued permits be attached to the agreement prior to work commencement when applicable.

Change Orders

Define a written change-order process with cost and time adjustments, required approvals, and documentation standards to control scope creep and prevent payment disputes.

Where Signed Agreements Are Sent and Stored

Typical routing shows who receives copies and where originals are retained for permitting, lender review, and contractor records.

Owner copy: Original retained by owner for records.
Lender review: Provide executed agreement to lender if financing is involved.
Building department: Attach executed agreement or plans to permit application when required.
Contractor file: Contractor retains signed contract, change orders, and inspection records.

Common Preparation Pitfalls to Avoid

Vague scope descriptions that lead to disputes over deliverables and extra charges.
Missing or mismatched legal names that delay lender review or title recording.
Unspecified permit responsibilities causing work stoppages or code violations.
Improperly documented change orders that create payment and schedule disputes.

Risks and Potential Consequences of Errors

Construction Liens: Improper notice or payment terms can enable subcontractors to record liens.

Permit Violations: Starting work without required permits can result in fines and reinstatement costs.

Recording Delays: Name mismatches or missing notarizations delay title matters and financing.

Payment Disputes: Undefined milestones or retainage heighten litigation risk and cash-flow issues.

Insurance Gaps: Insufficient insurance or certificates may leave parties exposed to liability.

Warranty Gaps: Failure to specify warranty terms can limit remedies for defects.

Project Dates and Contractual Deadlines to Specify

Key dates and deadlines within an addition project affect permits, payments, lien rights, and warranty periods; set these explicitly in the agreement.

Effective Date:

Enter as MM/DD/YYYY; determines when obligations begin.

Permit Application:

Submit by date specified or before construction begins.

Commencement of Work:

Start work within agreed days after permit issuance.

Inspections Schedule:

List required inspections and responsible party for scheduling.

Final Acceptance:

Define acceptance criteria and sign-off timeline after completion.

Key Project Milestones

A sequential milestone timeline helps track permitting, mobilization, construction, and closeout stages for the addition project.
