Looks like they will either nonrenew your policy - or they may try to cancel for "noncompliance of a critical recommendation". My guess is they will nonrenew. Nevada regulations for homeowners:
Endorsement: HO 01 27 05 02
Statute: 687B.310 to 687B.420
Length of cancellation notice required for nonpayment
10 days
Length of cancellation notice required for other reasons (for a new policy)
10 days
Are there cancellation restrictions after __ days based on certain valid reasons?
Yes, after 60 days for nonpayment, material misrepresentation, substantial change in risk
If so, is the cancellation notice requirement lengthened?
Yes, 30 days for other than nonpayment
Is there a notice requirement for nonrenewal, or for policy changes?
Yes, 30 days for nonrenewal
