Texas · Occ. Code §1958.154Texas mold remediation certificate: what a seller must hand over

When licensed mold remediation is finished, the Texas license holder gives the owner a certificate of mold remediation within 10 days, in which a mold assessment license holder states the contamination was remediated – and whether the underlying cause was fixed (Occupations Code §1958.154). When the owner sells, the seller must give the buyer a copy of each certificate issued for the property in the five years before the sale. The TREC contract repeats this in ¶6E(11).

The rules

  1. The certificate (§1958.154(a))

    Within 10 days after remediation the license holder provides it; a mold assessment license holder states the contamination was remediated per the plan or protocol.

  2. Underlying cause

    If the assessor is reasonably certain the mold will not return from that cause, the certificate says the underlying cause was remediated.

  3. At sale (b)

    The seller gives the buyer a copy of each certificate issued for the property during the five years before the sale.

  4. In the contract

    TREC One to Four Family contract ¶6E(11): the seller must provide each certificate issued under §1958.154 in the preceding 5 years.

What the TC tracks

  • Ask the seller about mold remediation in the last five years.
  • Copies of every certificate delivered to the buyer during the option period.
  • The seller's disclosure answers matching the certificates.
