How are foundation problems handled in an Oklahoma home sale?

Reviewed by Preston, Oklahoma foundation repair consultant · Updated 2026-10-14

In short: In an Oklahoma home sale, foundation issues come up through four channels: the seller's disclosure form, the buyer's home inspection, the contract's inspection and repair window, and the lender's appraisal rules ¹³⁵⁶. The 2026 disclosure form asks directly about previous foundation repairs ². Lenders can require repair or a professional report before a loan closes ⁶⁷.

What does Oklahoma's seller disclosure law require?

The Residential Property Condition Disclosure Act (60 O.S. §831 et seq.) covers residential property with one or two dwelling units ¹. Key points ¹:

• A defect is a condition that would materially lower the property's value or impair the health or safety of future occupants.
• The seller gives either a disclosure statement or, if the seller never occupied the property and knows of no defects, a disclaimer statement. The form must be completed no more than 180 days before the buyer receives it.
• It must be delivered before an offer is accepted. A seller who later learns of a defect must promptly deliver an amended statement.
• A seller is not liable for defects disclosed before acceptance, or for things outside the seller's actual knowledge.
• Real estate licensees must disclose defects they actually know about, but have no duty to inspect.
• The buyer's remedy is actual damages, including repair cost, with no punitive damages. Suits must be filed within two years after transfer.
• Exemptions include court-ordered and certain foreclosure transfers and newly built, never-occupied homes.

What do home inspections cover?

Oklahoma home inspectors are licensed by the Construction Industries Board, need 90 hours of training and at least $50,000 in general liability insurance ⁴. An inspector may be disciplined for doing repair work, or being paid by a repair company, on a one- to four-unit property the inspector inspected within the prior year ⁴.

Under the state standards of practice ³:

• Inspectors must inspect the foundation, including slabs, piers, columns, posts and stem walls, and describe indicators of foundation or structural movement (see the symptom matrix).
• They are not required to enter crawl spaces with less than 18 inches of headroom or an opening smaller than 18 by 24 inches (see pier and beam crawl space).
• They are not required to determine causes, repair methods or materials, or to perform engineering.
• Reports must recommend that reported conditions be corrected, further evaluated or monitored. Further evaluation means analysis by a qualified professional, tradesman or service technician.

What is the sale contract timeline?

On the 2026 state Residential Sale Contract ⁵:

• The buyer's inspection period is 10 days after the Time Reference Date if left blank.
• Buyers may use licensed home inspectors, architects and registered professional engineers; a structural inspection is a listed option.
• Within 24 hours after the period ends, the buyer either cancels or delivers a repair list (Treatments, Repairs and Replacements).
• The parties then have 7 days, if left blank, to negotiate. Agreed repairs are completed by the seller before closing at the seller's expense unless agreed otherwise.
• If the buyer does nothing within the deadlines, the buyer accepts the property regardless of its condition.

What do lenders require?

• Conventional (Fannie Mae). Deficiencies affecting safety, soundness or structural integrity make the appraisal "subject to" repair. A property rated C6 is ineligible until repaired. For abnormal settlement, the lender must show it was corrected or provide a professionally prepared report that it poses no threat of structural damage ⁶.
• FHA. HUD appraisal training lists cracked masonry or foundation damage, drainage problems including standing water against the foundation, and structural failure in framing among conditions requiring further inspection or repair by qualified individuals ⁷.
