Shop spray foam insulation in Beaumont is mostly work on the third bay of an attached garage rather than on a separate building, because the lots here were laid out with the vehicle accommodation built into the house.
A third bay that was always going to be a shop
The triple garage is close to standard on a Beaumont house, and in a very large number of them the third bay never holds a vehicle. It becomes the bench, the tools, the bikes, and the place a household does the things there is no room for indoors. That means a shop here is not a detached building on a yard, it is a bay inside the footprint of the house, sharing a wall with the other two bays and frequently a ceiling with a room above. The work is therefore an interior envelope problem rather than a building envelope one.
Dividing a bay off from the rest of the garage
The useful scope on almost all of these is a partition and a decision. There is no sense conditioning three bays when one is being used, and a sealed insulated bay inside a larger cold garage warms up quickly and cheaply. The condition is that the partition has to be built and sealed as an exterior surface, because it now has an unheated volume on the other side of it, and it has to run right up to the underside of the deck rather than stopping at a suspended ceiling. Done that way it is a small job. Done as a stud wall with batt in it, it achieves very little.
What it means to heat a space that is inside the house
A detached shop that is heated badly costs money. A bay inside the building envelope that is heated badly does something worse: it puts warm moist air against surfaces shared with living space, and it moves whatever is in that air, including exhaust and anything used at the bench, toward rooms people sleep in. That is why the wall and ceiling shared with the house are treated as a separation before they are treated as insulation, and why ventilation for the bay is decided at the same time as the envelope rather than afterwards.
The covering, and the fact that this space is occupied
Where a Beaumont shop bay is a space people work in, the foam has to be covered with a thermal barrier, and the surfaces shared with the house have their own separation requirement on top of that. Both belong in the quote from the beginning. It is also worth deciding at that point what the bay might become, because the covering follows the use, and a space that turns into a workshop with a welder in it later carries clearance requirements a storage bay does not.

Shop Spray Foam Insulation Beaumont: Common Questions
Should we heat the whole garage? Almost never. Partition the bay you use and seal it properly from the rest.
Is it different because it is attached? Yes. What you put into the air ends up next to living space, so ventilation is part of the job.
Can we do it later? You can, but the partition and the covering are far cheaper decided together than added separately.
