Ohio Builders Risk: Identify the Site Operator and Permit Boundary

Ohio’s NPDES construction rules include smaller phases within a qualifying common plan, and the permit application identifies the owner or operator, coordinates and ground-disturbance boundary. EPA issues NPDES permits on tribal lands in Ohio; Ohio EPA issues permits elsewhere. Give the broker the exact parcel, work boundary and operator rather than assuming the developer and contractor roles are interchangeable.

What Is Builders Risk Insurance?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. Read the national Builders risk guide.

What Should You Watch for With Builders Risk Insurance in Ohio?

Count the full common plan
Ohio’s NPDES rules include construction below one acre when it is part of a larger common plan of at least one acre; the small-construction category is limited to one to under five acres unless separately designated. Routine maintenance that preserves line, grade, hydraulic capacity or original purpose is excluded from that definition. ¹
Name the actual operator
For construction stormwater coverage, Ohio’s NOI rule asks for the owner or operator’s identity, project coordinates and a map outlining the ground-disturbance boundary. The operational-control role may differ from the property owner. Tell the broker who owns the project, directs daily site work and owns stored materials. ²
Check permit authority by parcel
EPA says it issues NPDES permits for Ohio tribal lands, while Ohio EPA issues other NPDES permits. If a project crosses or abuts tribal jurisdiction, identify each project parcel and ask which operator and property locations the proposed policy names. ³

Surplus-Lines Tax and Stamping Office in Ohio

Reported tax rate. 5% of gross premium, net of return premiums ^7,^8,⁹

For Ohio-home-state surplus-lines placements, Ohio sets a 5% tax on gross premiums after returned premiums and requires the surplus-lines broker to collect it when the policy is delivered. A diligent search usually applies; a qualifying exempt commercial purchaser may request nonadmitted placement in writing after disclosure that authorized-market coverage may offer greater protection, and the policy requires a signed notice of no Ohio guaranty-association benefits.

Who owns the project, controls daily construction and operates the stormwater permit?
Does the project include phases or parcels within a common development plan, and where is the disturbance boundary?
Is any property in tribal jurisdiction, and which agency has NPDES authority for that parcel?
Which materials, existing structures and contractor equipment are separately addressed in the quote?
