Full Breakdown
Under City of Miami Code § 10-5(e), the Building Official may not issue a permit for new construction, alteration, or addition unless the fire sprinkler documents are prepared by an engineer registered under Florida Statutes Chapter 471 or an architect registered under Chapter 481, Part I, whenever the fire sprinkler system contains 50 or more sprinkler heads. Below that threshold, Chapter 633, Florida Statutes-certified fire protection personnel may design the system themselves, and the same personnel can also handle limited alterations (adding, relocating, or deleting up to 249 heads) to an existing system without engaging a design professional, subject to the conditions spelled out in the section.
Violations & Fines
Filing sprinkler plans for a 50-plus-head system without a sealed design from a registered engineer or architect gets the application rejected by the Building Official; work performed without an approved, properly sealed plan is subject to a stop-work order and denial of the certificate of occupancy.
