The other day I received a call from a manufactured home retailer who was concerned because a code official refused to issue a building permit unless the installation documents were better organized. The code official wanted the installation details to be organized with a “Manufactured Home Building Permit Application Cover Page”. Other installers in the area had begun using this document to organize the pages, tables and charts from the home manufacturer’s installation manual instead of just using a pier print. As a result, this code official was so impressed that she now requires this cover page for all manufactured home permit applications.
If you are not familiar with the “Manufactured Home Building Permit Application Cover Page” click HERE. It is a simple one-page document where the installer can go through the manufacturer’s installation instructions to organize and detail the information needed for a proper installation. Plus, it is a great start to installer record keeping that is required for all new home installations.

This made me think, are there other improvements to manufactured housing installation that are starting to catch on? Well, yes there are! Here are a few that I have recently observed:
Independently Supported Patio Covers and Carports
While monitoring several installations in Michigan, I was impressed to see how posts and columns were properly installed along the front and back of the carports and patio covers to assure they are independently supported. Just lagging the hanging rail to the home will overload the home, and can possibly lead to structural failure in a wind storm event. If you are still using the manufactured home to support these accessory structures, you need to watch this video HERE.
It clearly shows how attaching a carport, patio cover, or similar structure to a manufactured home (that was not designed for such an attachment), can lead to a structural failure of the home.
Not only are installers in Michigan improving their installations, but here is a home in Pennsylvania where the porch roof supports itself and does not add additional loads on the home.
Porches Isolated From the Crawl Space
I have finally begun to see installations where the skirting or crawl space enclosure separates the porch area from the rest of the crawl space. We all know that water under the home is a huge problem, and rain water coming through floor decking boards and allowing this water to collect in the crawl space is a big problem.
Finally, I have been seeing installations where barriers are provided to isolate the porch area from the rest of the crawl space, and the skirting around the porch is held above grade to allow any water that comes through the decking board to flow away from the home.
Attaching skirting directly on the siding of the home has been the conventional method of skirting application for years, simply because it is easy. However, this application has led to water infiltration, poor performance and appearance of the siding. It is extremely encouraging to see how many installers are now attaching skirting under the home.
Installation Check Lists
I am seeing quite a few installers have begun to use the installation check list, and have started to customize the enhanced checklist to better fit their particular installations. These checklists, along with the building permit cover page, go a long way to reduce the liability of the installer. Check out this post and download your own copy of the Expanded Installation Checklist.
Manufacturers Getting On Board
As reported in our last post, New Installer Resource & Upcoming Training Available, Clayton Homes started publishing a quarterly newsletter designed to improve installation. Also, I have seen that the Commodore Corp. has been providing their retailers/installers with some home specific foundation details to help streamline the installation process. I am sure that there are some other manufacturers doing similar things, and I hope more follow suit.
Bottom line, the installation process is slowly changing for the better. So, as a professional installer, you should want to be in front of these changes and use them to your advantage.
