§ 498B. — (1) The local housing authority shall not approve an application for a common parts grant in respect of a building unless they are satisfied that on completion of the relevant works the common parts of the building will be in reasonable repair.
503§ (2) If in the opinion of the authority the relevant works are more extensive than is necessary for the purpose of securing that the common parts of the building will attain that standard, the authority may, with the consent of the applicant, treat the application as varied so that the relevant works include only such works as seem to the authority necessary for that purpose; and they may then approve the application as so varied.
