Modular Home Construction Codes Update

If you are in the market for a new home, you may have heard that the state-wide building codes for Pennsylvania were in the process of being updated. This set of codes applies to all residential construction that is not HUD-code (single-wides or sectionals). It applies to site-built and pre-fabricated homes as well as modular. Well, those updates are done, and now we are seeing the impact. The bottom line is this: There will be additional costs (of course), but you will be getting value for your money.

The major items in the 2015 update are:


  • Higher R-values for sidewall and ceiling insulation.
  • Argon gas in all windows.
  • Hot water pipes must have foam pipe insulation.
  • A whole-house ventilation fan is now required.
  • Any doors going to basements or attics must be insulated and have weather stripping.
  • If there is a hatch to access the attic, it must be insulated and have a gasket.
  • 1.3 gallon flush toilets are now required.


The last date that anything will be built to the old (2009) code is April 1st. That means that if you want to order a home under the old standards, it will have to be done pretty quickly. We know that no one likes to spend more money, but the additional costs are in areas that should pay you back over time, which should help ease the sting a little bit. As always, we are here to answer your questions.
