Question SBCC Hurricane Standards - links or

Ever so slowly working on purchasing a lot and planning to build a new house. We absolutely want to exceed the Florida Building Code and it is my understanding that the SBCC Hurricane Standards far exceed the generally excepted FL Codes.

Not so easy to find any links online that contains the actual construction standards.
Bueller, anyone ?

Thanks!

SBCC and Florida code are entirely separate..I can't believe SBCC is superior in any way.

Frankly, you should stick to the Florida code. Use the portion pertaining to the "high velocity" criteria used in South Florida if you want.

Besides, this isn't YOUR concern. You're still gonna have an engineer/architect sign off on the construction documents. Have the design professional design to the south Florida requirements. Once the plans are sealed and approved, you can't make arbitrary changes without resubmitting the changes for approval.

You may want to check and see what the Dade County Florida building codes are.

Seem like they are pretty extreme from what I remember. I know they are real tight on the rooftop HVAC equipment down there. Crazy wind loads and such.

Thanks and yes, it is my concern. If one code allows for a standard roof and 2 x 4's and SBCC Codes call for the use of 2" x 6" studs and hip roofs with say a 4 degree pitch, I want my builder to adhere to a more stringent code. We are building on Innerarity Island in Pensacola and I am sure Miami Dade Codes are extreme after Andrew and I lived in Broward when that hit and Miami Dade was tore up.

2x4 vs. 2x6 is somewhat irrelevant from a "strength" perspective. Roof pitch is hardly ever expressed in degrees. Wind loads create lateral shear, uplift, pressure. Design elements other than wall thickness are more important. The greatest advantage of 2x6 walls is insulation.

Built to higher standards with better materials, proper engineering, roof design, slope and fastenings will have an effect on strength of the house and the cost of insurance as I know it and actual performance under high wind stress. The higher the slope the more venturi (suction effect) on the opposite side of the roof wind slide. Hip roof design has no flat slides that can be pushed at by heavy winds. Of course, the added benefit of the heavier construction.

All those issues are addressed in the building code, along with a hundred other parameters. EVERYTHING! is addressed in the Florida code. What you say is "Design for 200 mph conditions" if your area calls for 160 mph conditions. There's also 2 methods of design (I think)..sustained wind and periodic gusts.

Why wood construction? While wood can be very hurricane resistant, it is NOT termite resistant, and requires a pootload of fasteners, which should be stainless in a slat air environment.

It used to not be that extreme, and certain inspectors used to allow "exceptions" in exchange for "due consideration" ... and then Andrew happened.

I still vividly remember the sight of flattened Homestead after the storm went through. Just ... rubble piles. Debris piles that used to be homes. No street signs. Every so often you'd see what used to be a house with a street address and insurance company name spray-painted on it, and hopefully from that you could orient yourself.

I know somebody who moved down from Pennsylvania a couple of years ago and got all butthurt about the building codes. He has no concept of what he's complaining about.

Andrew was a wake-up call. Not only were existing building codes inadequate, but compliance with existing codes was pretty poor.

In response, Florida developed its own code at the turn of the millennium, and have continued to refine it since then. The code is heavily weighted towards wind pressures and the resistance to these pressures. Applications and materials are tested to assure compliance with these pressures and forces.

The new updated code which went into affect last year is energy efficiency driven in addition to resistance to wind pressures.

Problem is..while it's viable to comply for new construction, it's a bitch on remodeling. Bureaucracy has overwhelmed common sense, and many existing homes cannot be updated cost effectively. The new energy code crap is downright stoopid when applying it to existing structures. Hey, I'm all for energy efficiency ( I live in an ICF home), but trying to meet the new code requirements in a 30 year old house is an exercise in frustration!
