If the plans, specifications, allowances and square-footage computations are not available when an Oklahoma new-home contract is signed, the 2026 OREC form provides a delivery and review sequence. Do not fill that gap with a brochure or verbal promise. Calendar the contract’s delivery deadline, compare the complete documents, and send any cancellation notice exactly as the signed agreement requires.
The marketing floor plan is not the full contract package
A website rendering can help a buyer choose a model, but it may omit the actual elevation, structural options, materials, allowance amounts, lot-specific orientation and measurement method. The signed form and attached documents control the deal, subject to builder addenda and negotiated terms.
Create a document index at signing. List what was delivered, what is missing, who must provide it, the due date and the exact notice recipient. Save the version of every file so a later revision cannot silently replace the set you reviewed.

What to compare during the review period
Match room dimensions, exterior elevation, garage orientation, windows, doors, ceiling heights, major systems, energy features, finish specifications, allowances and included options. Check the square-footage computation and identify spaces that may be excluded or measured differently.
Mark every mismatch between the sales presentation and the delivered documents. Resolve it in a signed writing. A salesperson’s text can flag the issue, but it may not satisfy the contract’s amendment or notice requirements.

Calendar delivery, review and cancellation separately
The official form uses a defined sequence rather than one generic inspection period. A builder’s addendum may alter rights or procedures, so use the signed package and obtain legal advice when language conflicts or a deadline is unclear.
If the documents arrive late or incomplete, do not assume the review period automatically restarts in the way you expect. Record receipt, identify the missing item and ask the broker and attorney how to preserve the buyer’s contract rights.
Keep the approved set through closing
After review, maintain one approved plans-and-specifications set. Tie later selections and change orders back to it. At walkthroughs, use the record to identify differences without treating a visual observation as a legal conclusion.
The practical next step is a line-by-line document meeting before selections or construction momentum makes changes expensive. OKC Metro Group can coordinate the real-estate timeline; contract interpretation belongs with an Oklahoma attorney.
Work through a missing-document scenario
Suppose the buyer signs on Monday with only a marketing floor plan. The builder later sends plans but omits the allowance sheet and square-footage computation. The buyer should record what arrived and when, identify the missing pieces in writing, and review the signed notice provisions before assuming the review clock has or has not started.
The same discipline applies if files arrive through several portals or email threads. Download them, label the versions, and ask for one complete package. A fragmented delivery can make it difficult to prove what the buyer actually reviewed.
Separate document review from construction inspection
Plans review asks what the parties agreed to build. Inspection asks what is being built and whether observed work raises condition or performance concerns. A perfect plan set does not replace pre-drywall, final or specialized inspections, and an inspection does not rewrite missing specifications.
Before closing, compare the approved document set, signed change orders, selection sheets, inspection reports and walkthrough list. Resolve discrepancies through the contract process. This creates a durable ownership file for future warranty questions, insurance claims, maintenance and resale. The file should identify the builder’s final approved revision, supplied permits and inspections, appliance and system model numbers, warranty contacts and owner maintenance required to preserve coverage. Photograph labels and installed selections without implying the photos amend the contract. If the builder portal will close after completion, download every buyer-accessible record first. A well-organized file lets the buyer, inspector, lender, insurer and attorney work from the same evidence instead of reconstructing promises after walls are closed and staff have moved to another project. Before releasing the final walkthrough item, ask which documents remain outstanding and assign a responsible party and due date to each one. Keep that list separate from cosmetic punch items so a missing warranty, plan revision or inspection record cannot disappear inside a longer finish list. After receipt, confirm the files open and the revision dates match the approved construction record.
