Tie it into the bungalow or let it stand on its own posts?
An attached cover borrows the house for half its structure, which is exactly the appeal and exactly the problem on a Montrose bungalow. The ledger board has to bolt into rafters or a top plate that was framed in the 1930s with lumber that has dried, shrunk, and sometimes been notched by eighty years of electricians and plumbers. When the framing is sound, attaching gives you a clean roofline and a cover that feels like a room. When it is not, reinforcing the wall and roof edge to take the load can cost more than the cover itself, and that is where a freestanding structure starts to make sense.
A freestanding cover sits on its own footings a few inches off the house and carries its own roof, so nothing new loads the original framing. The gap is flashed or bridged so the two roofs shed water cleanly, and on a compact lot the posts land where they will not block the walkway between the house and the fence. Behind a newer townhome the choice often goes the other way, since the framing is modern and an attached cover keeps the courtyard open. We inspect the eave and the attic side of the wall before recommending either, because the answer lives in the existing lumber, not in a catalog.
