Nev. Rev. Stat. § 40.507

1. A secured lender may enter and inspect real collateral for the purpose of determining the existence, location, nature and magnitude of any past, present or threatened release or presence of a hazardous substance from, in, into or onto it: (a) Upon reasonable belief of the existence of a past, present or threatened release or the presence of any hazardous substance from, in, into or onto it not previously disclosed in writing to the secured lender in conjunction with the making, renewal or modification of a loan, extension of credit, guaranty or other obligation involving the debtor; or (b) After the commencement of a trustee's sale or judicial foreclosure proceedings against the real collateral.

2. A secured lender shall not abuse the right of entry and inspection or use it to harass the debtor or tenant of the property. Except in case of an emergency, when the debtor or tenant of the property has abandoned the premises, or if it is impracticable to do so, a secured lender shall give the debtor or tenant of the property reasonable notice of intent to enter, and enter only during the debtor's or tenant's normal business hours. Twenty-four hours' notice is presumed to be reasonable in the absence of evidence to the contrary.

3. If a secured lender is refused the right of entry and inspection by the debtor or tenant of the property, or is otherwise unable to enter and inspect the property without a breach of the peace, the secured lender may, upon petition, obtain an order from a court of competent jurisdiction to exercise the secured lender’s rights under subsection 1.
