Deed restrictions must explain and disclose that:
(a) 
The enclosure is likely to be inundated by floodwaters which may result in damage and/or inconvenience;
(b) 
The depth of flooding that the enclosure would experience to the flood hazard area design flood elevation; and
(c) 
The deed restriction prohibits habitation of the enclosure and explains that converting the enclosure into a habitable area may subject the property owner to enforcement.
Garages and accessory storage structures shall be designed and constructed in accordance with the Uniform Construction Code.
All manufactured homes installed in flood hazard areas shall be installed pursuant to the Nationally Preemptive Manufactured Home Construction and Safety Standards Program (24 CFR 3280) and shall comply with the following requirements:
A. 
Elevation. All new, relocated, and replacement manufactured homes to be placed or substantially improved in a flood hazard area shall be elevated such that the bottom of the frame is elevated to or above the elevation specified in § 200-338.
B. 
Foundations. All new, relocated, and replacement manufactured homes, including substantial improvement of existing manufactured homes, shall be placed on foundations as specified by the manufacturer only if the manufacturer's installation instructions specify that the home has been designed for flood-resistant considerations and provides the conditions of applicability for velocities, depths, or wave action as required by 24 CFR Part 3285-302. The Floodplain Administrator is authorized to determine whether the design meets or exceeds the performance necessary based upon the proposed site location conditions as a precondition of issuing a flood damage prevention permit. If the Floodplain Administrator determines that the home's performance standards will not withstand the flood loads in the proposed location, the applicant must propose a design certified by a New Jersey licensed design professional and in accordance with 24 CFR 3285.301(c) and (d) which conforms with ASCE 24, the accepted standard of engineering practice for flood-resistant design and construction.
C. 
Anchoring. All new, relocated, and replacement manufactured homes to be placed or substantially improved in a flood hazard area shall be installed using methods and practices which minimize flood damage and shall be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces.
D. 
Enclosures. Fully enclosed areas below elevated manufactured homes shall comply with the requirements of § 200-338.
E. 
Protection of mechanical equipment and outside appliances. Mechanical equipment and outside appliances shall be elevated to or above the elevation of the bottom of the frame required in § 200-338 of this Part 6. An exception shall be where such equipment and appliances are designed and installed to prevent water from entering or accumulating within their components and the systems are constructed to resist hydrostatic and hydrodynamic loads and stresses, including the effects of buoyancy, during the occurrence of flooding up to the elevation required by § 200-338, the systems and equipment shall be permitted to be located below that elevation. Electrical wiring systems shall be permitted below the design flood elevation provided they conform to the provisions of NFPA 70 (National Electric Code).
