How Much Deposit Can a Contractor Ask For in New Jersey?
New Jersey sets no deposit cap, but a home improvement contractor must be registered, every contract over $500 must be in writing, and the contractor must carry $500,000 liability insurance.
New Jersey protects a homeowner's deposit through its Contractors' Registration Act rather than a percentage cap. No one may be in the business of making or selling home improvements unless registered with the Division of Consumer Affairs,1 every home improvement contract over $500 must be in writing,2 and a registered contractor must carry commercial general liability insurance.3 This page explains those requirements.
Registration and a written contract
The threshold protection is registration. No person may offer to perform, or engage or attempt to engage in the business of making or selling home improvements unless registered with the Division of Consumer Affairs.1 Confirming a contractor is registered before you pay a deposit is the step that keeps the Act's protections available to you.
The agreement has to be written. Every home improvement contract for a purchase price in excess of $500, and all changes in its terms and conditions, must be in writing.2 The written contract is where the price and any deposit are fixed, which is what makes a large up-front demand easy to spot.
The insurance a registered contractor must carry
New Jersey backs registration with an insurance requirement. Every registered contractor engaged in home improvements must secure, maintain, and file with the director proof of commercial general liability insurance in a minimum amount of $500,000 per occurrence.3 That coverage is a floor a legitimate contractor is expected to meet.
The practical takeaway in New Jersey is to confirm registration, get the job in writing, and keep the deposit proportionate, since the state relies on registration, a written contract, and mandatory insurance rather than a statutory deposit ceiling.
