§ 383. Construction with other laws; severability. 1. The provisions of this article and of the uniform fire prevention and building code shall supersede any other provision of a general, special or local law, ordinance, administrative code, rule or regulation inconsistent or in conflict therewith provided however:

a. Nothing herein shall impair the validity of any action taken pursuant to or in compliance with such law or regulation before the effective date of the uniform code; and

b. Any improvement, modification, alteration, adaptation, redesign or repair required by or pursuant to any general, special or local law, administrative code, rule or regulation enacted and effective before the effective date of the uniform code shall be made in the manner and within the time so required.

c. That, in cities with a population of over one million, the existing building and fire prevention codes shall continue in full force and effect beyond January one, nineteen hundred eighty-four unless the council, after analysis and consultation with the building and fire officials of such cities, shall determine that said local code provisions are less stringent than the uniform code. Existing local statutory, regulatory and administrative laws and provisions of such cities shall continue in full force and effect unless the foregoing is determined by the council. Notwithstanding this paragraph, when such factory manufactured homes are intended for use as one or two family dwelling units or multiple dwellings of not more than two stories in height, provided such multiple dwellings are not intended for use as hotels or motels, the provisions of this article and of the uniform fire prevention and building code pertaining to factory manufactured homes shall supersede any other provision of general, special or local law, ordinance, administrative code, rule or regulation inconsistent or in conflict therewith.

2. Nothing herein shall be construed as affecting the authority of the state labor department to enforce a safety or health standard issued under provisions of sections twenty-seven and twenty-seven-a of the labor law.

3. Nothing herein shall be construed to relieve a person from complying with a stricter standard issued pursuant to the Occupational Safety and Health Act of 1970, as amended.

4. If any section of this article or the application thereof to any person or circumstances shall be adjudged invalid by a court of competent jurisdiction, such order or judgment shall be confined in its operation to the controversy in which it was rendered, and shall not affect or invalidate the remainder of any provision of any section or the application of any part thereof to any other person or circumstances and to this end the provisions of each section of the article are hereby declared to be separable.
