With which codes do your plans comply?
These plans, and associated documents have been prepared to comply with the latest adopted version of the International Residential Code (IRC) or, if you’re building in those areas,Oregon / Washington Residential Specialty Code (O.R.S.C. / W.R.S.C.).
Each state in the US adopts a building code as their base code. Over the years, there have been several national code standards for states to choose from, but now the International Residential Code has become very widely accepted as the standard base code. For this reason, we choose to follow the IRC in developing our plans. Unfortunately, each state can modify the base code with their own state adopted amendments, and may chose not to adopt certain sections of the base code. Energy requirements are a common section that is heavily modified or replaced by a different model code, by each state.
To further complicate the issue, the base code is revised every three years or so, and states vary in their timing of when they adopt each new code version --- a year or more delay in adopting the latest code is very common. Beyond that, every local permit issuing jurisdiction within each state (counties, cities, etc.) can further amend the state requirements. Aware of this reality, our staff knows to never promise that our plans will be able to meet every requirement of every jurisdiction in the country. We do make every effort to comply with the national base code, and beyond that, we provide follow-up support where possible, to help our customers to meet the amended codes of their jurisdiction.
How do I address changes on the plans?
To satisfy the requirements of most building departments, we recommend that you have the plans revised to properly account for your alterations. Our staff can assist you with this, or you can enlist the services of a design professional in your area. In either case, don’t wait till the last minute!Plan ahead and allow adequate time for review of structural design changes.
Frequently Asked Questions
How do we address high wind and seismic design criteria?
Our stock plans require additional structural information and detailing in order to meet high wind and seismic requirements, which vary by geographic location and legal jurisdiction. For an additional fee, we can provide engineering to meet specific seismic zone, wind speed and wind exposure values for a specific building site. Such engineering analysis is site-specific and requires additional time to prepare. The engineering plan is done with the supporting calculations, stamped by a licensed engineer are typically available for Oregon or Washington within a few days — check with our staff for availability in other states.
Is beam calculations included with the plan?
Yes, vertical gravity load calculations are either included with your plans, or available for a nominal shipping/handling fee. These calculations do not carry a stamp from an engineer. Again, if an engineer's stamp is required, you will have to make the appropriate arrangements, and allow for the added time and expense involved.
