Non-Standard General Contractors Mono-line Property Insurance

Home > General Contractors Insurance Guide > Non-Standard General Contractors Mono-line Property

This page is part of the broader General Contractors Insurance Guide. For general contractors, property insurance, such as the Commercial Auto Insurance and Workers Compensation insurance, plays a crucial role in a comprehensive insurance program. This coverage provides essential protection for your valuable tools and materials, ensuring both compliance and security against property loss.

General contractors need property insurance to protect both real property (such as office buildings or storage facilities) and personal property (like tools, machinery, and materials) used in their day-to-day operations.

Given the unique risks associated with job sites, including equipment movement and varying compliance requirements, having appropriate property insurance isn't just a safeguard; it's often a contractual necessity. This coverage can protect against potential liabilities for lost or damaged tools and materials, ensuring smoother operations.

A Non-Standard Mono-line property insurance policy may be necessary when:

  • Standard carriers limit or exclude coverage for valuable machinery, mobile equipment, or building materials that move between job sites.
  • The contractor faces unique or high-risk exposures that require a customized, stand-alone property policy.

Non-Standard General Contractors Mono-line Property insurance is a tailored commercial property policy designed specifically for general contractors. It helps protect against property loss or damage related to construction operations.

Given the unique risks faced by general contractors, having appropriate property insurance isn't just a safeguard but often a requirement for compliance with project contracts. This can protect against potential liabilities for lost or damaged tools and materials, ensuring smoother operations.

What is Non-Standard General Contractors Mono-line Property?

This type of insurance is a stand-alone property policy for general contractors whose needs fall outside the guidelines of standard insurance carriers. It focuses on protecting owned or used property critical to construction work, especially when equipment and materials are frequently moved between sites or stored off-site.

Who Needs It

General contractors who own expensive tools, mobile equipment, or building materials may need a non-standard policy. It’s particularly useful for contractors working on multiple sites, those with high-value assets, or companies that have previously been declined standard coverage due to claims history or unusual risks.

What It Typically Covers

  • Movable equipment and tools
  • Job site materials in transit or storage
  • Temporary structures like trailers or sheds
  • Office or warehouse property used in the business
  • Damage from fire, theft, vandalism, or certain weather events

Common Exclusions and Limitations

Policies may not cover wear and tear, faulty workmanship, intentional damage, or losses from unapproved usage. Flood and earthquake coverage may be excluded unless specifically added. Each policy varies, so it’s important to review terms carefully.

Factors That Influence Cost

  • Type and value of insured property
  • Number and location of job sites
  • Claims history and risk profile
  • Security features and storage practices
  • Policy limits and selected deductibles

Proof of Insurance and Compliance

Having property insurance may be required by project owners, lenders, or local regulations. A certificate of insurance (COI) serves as proof of coverage and may be needed to secure contracts or permits. Requirements vary by state and project type.
