AB-559: New Rules for Home Improvement Contracts

This proposal adds accessory dwelling units to the definition of home improvement and sets stricter penalties, including license revocation and fines, for contractors who take payments without doing work.

What This Bill Does

  • Adds construction, erection, installation, replacement, or improvement of accessory dwelling units on residentially zoned property to the legal definition of 'home improvement'.
  • Keeps existing rules requiring written contracts that list the total price and limits downpayments to $1,000 or 10% of the cost.
  • Prohibits contractors from asking for payments larger than the value of work done or materials delivered.
  • Subjects licensees who take payments causing financial loss over 10% of the contract price to license revocation and a civil penalty of at least $10,000.

Who It Names or Affects

  • Licensed contractors (licensees) who sign home improvement contracts.
  • Unlicensed people who perform work on homes or accessory dwelling units.
  • Consumers hiring workers for construction, installation, or repair projects involving financial loss over 10% of the contract price.
