Is there a consensus on how to secure buildings to layout?

The Vintage Bus Tour Co. had brought a group of railfans for a visit to Hooker Junction where on the DC Central*, the buildings were just set in place:

Looking down into Hooker at an earlier time before the "new" interlocker was installed. The few bits of scenery were just st in place here, also:

*DC Central = Dirty Carpet Central

My personal opinion is that a consensus is never possible.    A compromise is possible in a lot of cases.

The other side of this is that I don't secure buildings to the layout in most cases.    If they are permanently secured they sometimes get in the way of maintenance and cleaning.   

Instead I locate them in place so they can't move sideways with pins.    I generally use small 3/4 inch long nails and usually clip the heads off.    Most buildings have open bottoms or some sort of opening.    I figure out where I want to locate the building and mark at least two corners.    I then measure from the these corners to the opening inside the building.    I then locate the nails underneath on the layout where the opening in the bottom of the building will be.     Then I can place the building on the layout on the locating pins.    I can scenic around the building and still be able to lift it off if needed.

You can use the same technique with a permanent foundation, just use longer pins so they are above the height of the foundation.    You make the foundation permanent but leave the building removable.

At MTH i would secure buildings with a block of wood in opposite corners, glued to the corner of the building on the inside and predrill and secure with a drywall screw from the underside, its good if the layout needs to be tilted or road transported like the York layout.
