Engineering Kits for Safety & Investment:

Your patio cover, lattice cover or carport cover Kit will be designed based on one of the two available Engineering Reports to comply with local code for safety and to keep your investment secure. If obtaining a permit you will want to contact your local Building Department or Governing Agency(s) to find out which Engineering Report will meet with their acceptance. Both Engineering Reports contain Roof Panel, Rafter and various types of Beam Spans with Detailed Drawings of Attachment and Connection Details.

Building Permits:

Generally a Building Permit is required whenever a permanent structure such as a patio cover or carport is attached to the home and in most cases Freestanding covers will need a permit also. Obtaining a Building Permit for your Patio or Carport Project is not part of our service; you will obtain your own permit. However, we help make the permit process easier by offering Product Specific Engineering with our kits which will generally make for a simple permit process.

Each Building Department has the authority to accept or decline product engineering and may allow variances or require additional requirements outside of the product engineering; contact your local Building Department and question them regarding your requirements.

We highly recommend for you to read our short article on how to obtain a building permit, it can save you time and effort when conferring with your Building Department.

U.S. State Engineering Stamps held by Engineer

In many cases local Building Departments will not accept Product Engineering Reports without a Stamp from a Licensed Engineer from your particular State. If the Engineer is not licensed for your state is does not automatically mean that your Building Dept. will not accept the Engineering Report so check with your local Building Dept. for particulars.

Awning Engineering 4 Basic Factors

  • Climate Factors:

    • Live Load or Ground Snow Load¹ (Pounds Per Square Foot)
    • Wind Factor (Miles Per Hour)
  • Regional Factors:

    • Exposure to Wind (Exposure B or C)
    • Seismic

Note ¹: The term "ground snow load" is different than the term "roof design load", if you're located in a snow climate use the proper terminology when consulting your building department in order to obtain the correct requirements for you area. Roof design load is a fraction of ground snow load as shown below for 30 pound and higher ground snow loads.

  • 10 lbs Ground Snow Load = 10 lbs Roof Design Load
  • 20 lbs Ground Snow Load = 20 lbs Roof Design Load
  • 30 lbs Ground Snow Load = 25.2 lbs Roof Design Load
  • 40 lbs Ground Snow Load = 33.6 lbs Roof Design Load
  • 60 lbs Ground Snow Load = 50.4 lbs Roof Design Load

Engineering Modeling Code Acronyms

Modeling Codes unify popular and safe building practices and standards saving building authorities the time and expense of drafting individual codes; manufacturers, contractors and homeowners benefit by submitting evaluation reports to building authorities based on Modeling Codes instead of each job requiring site specific engineering.

  • ICC (International Code Council): A group comprised of the 3 regional model code groups which includes the ICBO, BOCA and SBCCI. The three groups joined in 1997 to form the ICC; the ICC has created a set of national model building codes including the International Building Code.
  • IAPMO ES (International Association of Plumbing and Mechanical Officials): Typically used for Plumbing and Mechanical however now provides evaluation services for manufactured structures such as patio covers and carports. The evaluation process is to certify a product, material or design as compliant with section 1703 of the International Building Code (IBC). IAPMO evaluation reports are intended for nation wide building department approval; IAPMO ES is accredited by the American National Standards Institute (ANSI) and the evaluation reports and can be completed faster than any other third-party certification body.
  • ICBO (International Conference of Building Officials): West Coast Regional Code that has now joined with BOCA and SBCCI to form the ICC; ICBO Engineering Reports are being phased out by local Building Departments in favor of the IBC Engineering Reports. Note: Some refer to the ICBO as the International Council of Building Officials instead of the International Conference of Building Officials.
  • IBC (International Building Code): The IBC is a model code developed by the ICC and has replaced the ICBO, BOCA and SBCCI model codes; most Building Departments are requiring the IBC Engineering Report over the ICBO.
  • UBC (Uniform Building Code): Model Code created by the ICBO in 1927 and updated every 3 years until 2000 when the IBC replaced the UBC.
  • CBSC (California Building Standards Commission): CBSC is responsible for administering California's Public Safety Codes, including adopting, approving, publishing, and implementing codes and standards.
  • CBC (California Building Code): California Building Code adopted and approved by the California Building Standards Commission; the ICC 2006 Meets the 2007 CBC.
  • IRC (International Residential Code): Stand-alone residential code establishes minimum regulations for one and two-family dwellings of three stories or less. ICC 2006 Meets the IRC, " Anything that meets the IBC automatically meets the IRC as per 2006 IRC Section R301.1.3 last sentence" (Per Engineer of record for this product engineering.).

But my neighbor has it...

We hear this one much too often; just because your neighbor had his Patio Cover installed that way does not necessarily mean his Patio Cover meets code; a large number of Aluminum Patio Covers are installed not to product engineering requirements. Currently there is an epidemic with Non-Reputable Contractors and DIY Suppliers selling aluminum patio covers under the pretence that it is an Engineered Patio Cover when in fact it is not.

If you want to follow product engineering and obtain a Building Permit you may want to stop peaking over your neighbor's fence. Some Non-Reputable Companies supply engineering that has been "fudged" (not properly detailing the engineering report) and others do not offer any engineering at all. The companies that "fudge" engineering do it in order to sell a cheaper patio cover while telling the customer that it's an engineered patio cover. The companies selling patio covers not to product engineering requirements have no mind for the safety of your family or your long term investment; aesthetics and costs are important factors, however safety and durability should come first.

Credibility is a key factor when choosing a contractor or do-it-yourself supplier; if you are getting information regarding engineering that conflicts with our information we will go head to head in design with any competitor selling the same brand product.

What is "fudged" Engineering?: When we refer to non-reputable contractors and DIY suppliers that have "fudged" the Engineering we are referring to them incorrectly marking or highlighting the engineering report details that are pertinent to the job intentionally with the intent of misleading the building department in order to get a permit for a patio cover that does not meet the engineering requirements.

Mismarking the engineering may include highlighting the wrong column for post spacing, tributary widths, post thicknesses, pan thicknesses, rafter thicknesses, steel "C" beam insert gauges, attachment details, fascia details, leaving out secondary tables for complete engineering details, and so forth; by mismarking the engineering report the cover can be made to look like it meets the engineering requirements.

This is fraud and has been recognized by building departments because it has become such a big issue, it will become harder for the non-reputable companies to sneak "fudged" engineering through now that the building departments are working on ways to prevent engineering misrepresentations of this kind for your families safety.
