N.Y.C. Admin. Code § EBC A301: Section EBC A301: General

A301.1 Purpose.

The provisions of this chapter are intended to reduce the risk of lateral force induced damage to existing wood-frame residential buildings. The requirements in this chapter are prescriptive or schematic minimum standards intended to incrementally improve the lateral force resisting performance of residential buildings. Compliance with these provisions will not necessarily prevent damage due to earthquake, wind, or flood loading.

This chapter includes standards for strengthening that may be approved by the commissioner without requiring submittal of plans or calculations prepared by a registered design professional. The provisions of this chapter are not intended to prevent the use of any material or method of construction not prescribed herein. The commissioner may require that construction documents for strengthening using alternative materials or methods be prepared by a registered design professional.
