After a permit has been issued, the building inspector will want to be notified at various points during your build in order to do a site visit, walk around and inspect the details to make sure that they meet code requirements. These inspections are commonly at the point where excavation work is complete, when the foundation is completed but before back-filling, when framing and all structural work has been done, after the installation of the insulation and vapour barrier, and then a final inspection after everything is complete. You may need to have a separate plumbing inspector if you’re adding or changing plumbing fixtures, and electrical work will need to be inspected by the appropriate electrical inspector (in Ontario, the Electrical Safety Authority). In my experience, inspectors appreciate good work, a clean, safe site, and are willing to work with homeowners and builders to make sure that the work will meet code and will endure.
There are benefits to either approach. Sharing a common wall with your house can require some careful soundproofing but can reduce heat loss and exterior finishing costs like siding. A shop located in an addition is more likely to be allowed to have living space or storage space above it, and it may be easier to make use of the existing plumbing and electrical and heating systems of your home to service your shop space. Another advantage of an addition is not having to run to an outbuilding in minus-30-degree weather or a summer downpour.
You sure make “keeping up with the Spagnuolo’s” tough. :) The cart fits my space pretty well. I am somewhat limited so utilizing the space under the lumber rack works well for me. I have the stand alone scrap storage bin also but the extra scrap storage on the cart is a bonus. I always seem to have srcap lumber running out of my ears. I have a hard time throwing away even a small piece of walnut or other nice (expensive) wood.
Some of the most important decisions in laying out a shop involve the placement of basic machines, such as the table saw and jointer. Deciding where to put them depends in part on the scale of woodworking you do, which determines the clearance area around these machines if you need to handle long stock or large sheet goods. You’ll also want to consider work flow to avoid an excess amount of running around the shop to accomplish tasks, as well as how to power your machines without turning your shop into a snakepit of extension cords.
