Supplement to the 2010 Florida Building Code

Florida Building
Code, Building:
Chapter 1, Scope and Administration
105.3.1.2 Add text to read as shown.
105.3.1.2
No permit may be issued for any building construction, erection,
alteration, modification, repair, or addition unless the applicant for such
permit provides to the enforcing agency which issues the permit any of the
following documents which apply to the construction for which the permit is to
be issued and which shall be prepared by or under the direction of an engineer
registered under Chapter 471, Florida
Statutes:
1. Plumbing documents for any new building
or addition which requires a plumbing system with more than 250 fixture units
or which costs more than $50,000 125,000.
2. Fire sprinkler documents for any new building or addition which includes a fire sprinkler system which contains 50 or more sprinkler heads. A Contractor I, Contractor II, or Contractor IV, certified under Section 633.521 Florida Statutes, may design a fire sprinkler system of 49 or fewer heads and may design the alteration of an existing fire sprinkler system if the alteration consists of the relocation, addition or deletion of not more than 49 heads, notwithstanding the size of the existing fire sprinkler system.
3. Heating, ventilation, and air-conditioning
documents for any new building or addition which requires more than a
15-ton-per-system capacity which is designed to accommodate 100 or more persons
or for which the system costs more than $50,000 125,000.
This paragraph does not include any document for the replacement or repair of
an existing system in which the work does not require altering a structural
part of the building or for work on a residential one, two, three or
four-family structure.
An air-conditioning system may be designed by an installing
air-conditioning contractor certified under Chapter 489, Florida Statutes, to serve any building or addition which is
designed to accommodate fewer than 100 persons and requires an air-conditioning
system with a value of $50,000 125,000
or less; and when a 15-ton-per system or less is designed for a singular space
of a building and each 15-ton system or less has an independent duct system.
Systems not complying with the above require design documents that are to be
sealed by a professional engineer.
Example 1:
When a space has two 10-ton systems with each having an independent duct
system, the contractor may design these two systems since each unit (system) is
less than 15 tons.
Example 2:
Consider a small single-story office building which consists of six individual
offices where each office has a single three-ton package air conditioning heat
pump. The six heat pumps are connected to a single water cooling tower. The
cost of the entire heating, ventilation and air-conditioning work is $47,000
and the office building accommodates fewer than 100 persons. Because the six
mechanical units are connected to a common water tower this is considered to be
an 18-ton system. It therefore could not be designed by a mechanical or air
conditioning contractor.
NOTE: It
was further clarified by the Commission that the limiting criteria of 100
persons and $50,000 125,000 apply
to the building occupancy load and the cost for the total air-conditioning
system of the building.
4. Any specialized mechanical, electrical, or
plumbing document for any new building or addition which includes a medical
gas, oxygen, steam, vacuum, toxic air filtration, halon, or fire detection and
alarm system which costs more than
$5,000.
5. Electrical documents. See
Documents requiring an engineer seal by this part shall not be valid unless a professional engineer who possesses a valid certificate of registration has signed, dated, and stamped such document as provided in Section 471.025, Florida Statutes.
Section 105.8 Notice of commencement, add to read as shown.
105.8
Notice of commencement. As per
Section 713.135, Florida Statutes,
when any person applies for a building permit, the authority issuing such
permit shall print on the face of each permit card in no less than 18 14-point,
capitalized, boldfaced type: “WARNING TO
OWNER: YOUR FAILURE TO RECORD A NOTICE OF COMMENCEMENT MAY RESULT IN YOUR
PAYING TWICE FOR IMPROVEMENTS TO YOUR PROPERTY. IF YOU INTEND TO OBTAIN
FINANCING, CONSULT WITH YOUR LENDER OR AN ATTORNEY BEFORE RECORDING YOUR NOTICE
OF COMMENCEMENT.”
SECTION 2319
HIGH-VELOCITY HURRICANE ZONES - HORIZONTAL FRAMING
Section 2319.17.2.1.3 revise to read as shown.
2319.17.2.1.3 Roof trusses shall be designed for a minimum
live load of 30 psf (1436 Pa), a minimum dead load of 15 psf (718 Pa) on the
top chord, and a minimum dead load of 10 psf (479 Pa) on the bottom chord; and
wind loads per Chapter 16 of this code. Where the roof design is such that
water is not directed to the interior of the roof and there are no parapets or
other roof edge drainage obstructions, roof trusses with slopes of 11/2:12 or
greater may be designed for a live load of 20 psf (958 Pa) and a minimum total
load of 45 psf (2155 Pa). Adjustment of the allowable design stress for load
duration shall be in accordance with National Design Specification for Wood
Construction. except that load duration factor for
wind loads shall not exceed 1.33.
Section 2319.17.2.1.5 revise to read as shown.
2319.17.2.1.5 Flat roof trusses shall be designed for not
less than the loads set forth in Section 2319.17.2.1.3 above, except that the
dead load on the top chord may be taken as 10 psf (479 Pa) in lieu of 15 psf
(718 Pa), and the total load reduced to 50 psf (2394 Pa). Adjustment of the
allowable design stress for load duration shall be in accordance with National
Design Specification for Wood Construction. except
that load duration factor for wind loads shall not exceed 1.33.

minimum dead load of 15 psf (718 Pa) on the top chord, and a minimum dead load
of 10 psf (479 Pa) on the bottom chord; and wind loads per Section R4409 of this code. Where the roof design is
such that water is not directed to the interior of the roof and there are no
parapets or other roof edge drainage obstructions, roof trusses with slopes of
11/2:12
or greater may be designed for a live load of 20 psf (958 Pa) and a minimum
