Commercial Property Insurance in Delaware

Delaware’s residential flood-insurance model act expressly excludes commercial property, so do not assume its residential rate-filing and consumer-notice rules govern a business flood policy. DNREC identifies coastal surge, tidal flooding and year-round flood risk; use the site-level advisory tool as a prompt for review, not a complete risk map. 1,2,3

What Is Commercial Property?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. Read the national Commercial property guide.

What to Watch for in Delaware

  • Check Which Flood Rules Apply

    Delaware Code’s private primary residential flood insurance subchapter defines that coverage to exclude commercial property. Ask which policy form and state rules govern the business quote rather than relying on protections written for residential flood insurance. 1

  • Include Tidal and Coastal Flooding

    DNREC says Delaware faces year-round flood threats, including storm surge and tidal flooding in some coastal areas. Ask whether the building quote includes flood at all and whether the flood policy addresses the location’s coastal exposure. 2

  • Treat Advisory Flood Heights as a Starting Point

    DNREC’s flood-planning tool warns that its data may be inaccurate or omit flood sources, especially local drainage; it provides advisory flood heights and models. Ask the broker to compare the property elevation and drainage with current FEMA studies and the policy’s flood definition. 3

Who Regulates Insurance in Delaware

Delaware Department of Insurance

The Delaware Department of Insurance licenses and regulates insurers and insurance producers, reviews regulated insurance activity, and handles complaints. Its consumer division can help you raise an insurance concern and its services page links to official license searches. 4,5,6

Surplus-lines tax and stamping office

Reported tax rate: 3% of gross premium, less return premium, when Delaware is the home state When Delaware is the insured’s home state, its 3% surplus-lines premium tax applies to the entire premium of a multistate policy, less returned premiums and excluding federal and state taxes and examination fees. Ask the surplus-lines broker to confirm the home-state determination and tax calculation, and separately explain how exposures are allocated in the required reports; those allocations do not reduce the premium subject to Delaware’s tax. 7,8

Providers With Documented State Licenses

These providers publish a national listing for Commercial property; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Delaware. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

  • ERGO NEXT InsuranceNext First Insurance Agency, Inc.Insurance producer · checked 2026-09-28ERGO NEXT’s current license table lists Next First Insurance Agency, Inc. in 50 jurisdictions, including Washington, DC; New York is excluded because its table rows name Next Insurance Services and AP Intego, not Next First. The table is company-reported; it does not establish product availability or provide state-regulator verification for each entry. 13
  • TechInsuranceSpecialty Program Group LLCInsurance producer · checked 2026-09-28TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. 15
  • VouchVouch Specialty Insurance Services, LLCInsurance producer, Surplus-lines broker · checked 2026-09-28Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. 16

Questions to Ask Before You Buy in Delaware

  3. Did you compare the property with FEMA FIRM/FIS information as well as DNREC’s advisory tool?

Do Delaware’s residential flood insurance rules apply to commercial property? 1

Does Delaware’s flood-planning tool show every flood risk? 3,2

No. DNREC warns that its advisory data can be inaccurate or omit flood sources, including local drainage. Use it alongside authoritative FEMA mapping and a review of the property’s actual flood terms. 3,2
