Building Codes Compliance

Quality Standards for Prefabricated Homes

Guardian Homes by Keystone homes are built to pre-emptive national and statewide building codes which meet or exceed the same building codes used for conventional stick or site-built homes. In addition, the construction is certified by a bonded third-party inspection agency to assure the standards for quality, security and reliability in new home construction are met. Keystone Homes come with the peace of mind that they are designed and built to meet stringent quality standards established by the four major national standards organizations:

  1. American Society of Testing and Materials
  2. National Fire Protection Association
  3. American Standards Institution
  4. National Bureau of Standards of the United States Department of Commerce (NIST)
