Great question. But first, context.

Carriages were owned by the highest classes of society. This means every expense related to possessing such means of transportation would not be a burden to these people as they owned and controlled large sums of money. It also means that carriages were not a common thing and also that whenever they were seen around, it was never in such a large number that it would take a large place like a parking lot.

Carriages would, for this reason, remain in front of or very close-by the place where the person needed to go and wait. There is evidence of this in books and paintings but my favorite is a Portuguese expression used in theatre. Actors usually wish "a lot of shit" to each other before going into the stage. This comes from the time when only the high class went to the theatre (usually opera) and rode on carriages. The horses would remain by the front door the entire time their owner was in there, so at the end you'd find a lot of horse poop by the entrance. The bigger quantity of poop, the more successful the play, as it indicated a lot of people had come and stayed long enough for the horses to poop more than once.

This is also one of the reasons why there's a need for squares in front of buildings, as it provided "parking" for carriages.

Carriage owners usually owned a place for the horses and a place for the carriages and so did the lodges and hotels, the same way as they nowadays provide parking spots.

For the not so wealthy that still owned carriages or similar means of transport, it is all the same, with the exception that people usually lived in modest two-story houses so to keep the animals/carriages in the bottom floor and live on the top.
