Delaware Code
Subchapter III. Declinations, Renewals and Cancellations of Property Insurance Contracts
§ 4130. Nonrenewal [For application of this section, see 79 Del. Laws, c. 390, § 8].

(a) (1) An insurer may not refuse to renew a policy of homeowners insurance solely on the basis of:

a. Claims caused by weather, unless 3 or more such claims have been made against the policy during the 36 months immediately preceding the expiration of the current policy period; or
b. Claims not caused by weather, unless 2 or more claims have been made against the policy; or
c. A combination of claims caused by weather and claims not caused by weather, unless such combination of 3 or more claims has been made against the policy during the 48 months immediately preceding the expiration of the current policy period; or
d. Claims closed without payment, notwithstanding any other provision of this section.
(2) However, an insurer may nonrenew a homeowner's policy if:

a. The claim or claims asserted against the policy demonstrate that there has been a reasonably substantial change or increase in the hazard or in the risk assumed by the carrier subsequent to the date the policy was issued, and such nonrenewal is applied to other homeowners policies similarly situated; or
b. The policyholder has refused or failed to make reasonably necessary changes or repairs after being notified by the insurer that failure to make such changes or repairs will constitute a breach of contractual duties, conditions or warranties that will change or increase the hazard or risk assumed by the insurer subsequent to the date the policy was issued.
(b) “Homeowners insurance” for purposes of this section and § 4131 of this title shall mean property insurance as defined at §§ 4103(5)d. and 4120 of this title insuring any real or personal property used by a person as a permanent or temporary place of residence.
