Any deposit required under the contract to be paid in advance of      the commencement of work under said contract shall not exceed the greater of      one-third of the total contract price or the actual cost of any materials or      equipment of a special order or custom made nature, which must be ordered in      advance of the commencement of work, in order to assure that the project      will proceed on schedule. No final payment shall be demanded until the      contract is completed to the satisfaction of the parties thereto; 
(7) the signatures of all parties shall be affixed to the      contract; 
(8) there shall be a clear and conspicuous notice appearing in      the contract:

No contract shall contain an acceleration clause under which any      part or all of the balance not yet due may be declared due and payable      because the holder deems himself to be insecure.

At the time of signing, the owner shall be furnished with a copy      of the contract signed by both the contractor and the owner. No work shall      begin prior to the signing of the contract and transmittal to the owner of a      copy of such contract. 
Any contract entered into between a contractor and homeowner      shall require the contractor to inform the homeowner of the following: (i)      any and all necessary permits, (ii) that it shall be the obligation of the      contractor to obtain said permits, and (iii) that homeowners who secure      their own permits will be excluded from the guaranty fund provisions of this      chapter. 
Any contract entered into between a contractor and homeowner may      provide that the contractor may initiate alternative dispute resolution      through any private arbitration services approved by the director, under      paragraphs (a) to (e), inclusive, of section four; provided, that said      alternative dispute resolution provision is clearly and conspicuously      disclosed in the contract, in language designated by the director, and that      each party separately signs and dates the provision, thereby assenting to      the procedure. 
NOTE: Contracts which fail to comply with the requirements of      this section shall not be invalid solely because of noncompliance.
