“Space Cowboys” and “The Core” both used the same space shuttle interior set.
Mel Brooks used the same original props in “Frankenstein” in his “Young Frankenstein” spoof.
Here’s a page that has shots of Warner Bros.’ various exterior sets (New York, Small Town USA, etc). If you were an observant Dukes of Hazzard fan like I was growing up, you saw Hazzard’s town square (“Midwest Street”) in a lot of other TV shows.
The ship from Master and Commander is in San Diego next to authentic old ships as part of the San Diego Maritime Museum.
The ship from the Mel Gibson version of Mutiny on the Bounty is also still afloat:
Foxploration, a theme park in Baja California, Mexico, has the nearly life-sized Titanic ship exterior (which has only one side). Many sets and props from the movie are also on display.
Or the Predator turning up in Voyager 
If you happen to have Western or Nazi props, they’ll end up in Star Trek at some point 
Yeah, that’s true, but it was kind of a special case, if I remember correctly. The electrical doodads belonged to one man, Kenneth Strickfadden, and not to a studio per se.
IIRC, DeMille intentionally buried the set to keep other filmmakers from reusing it.
Marcus Welby, MD’s house was the same as the Cleaver’s (Leave it to Beaver) second house. Which was right down the street from the Munsters’ house. Also existing interior sets are often used to film TV pilots. They don’t want to bother building a set if the show isn’t picked up by the network.
No offense, but that is not all they ever built or used. Moving at a normal pace of walk, a Steadicam shot traverses a length of 25 foot hallway in under 10 seconds. Many long shots were done in the “hallways” on TNG. What you saw was one section, with likely both linear parts as wild walls so you could have an opposing wall and ceiling showing but wild out one wall to get lights or a camera into.
Hundreds of feet are made use of at times- but they all are construtcted the same way. That is NOT to argue with the idea that hallway and other generic look areas are reused and relit to make them look different. They are all the time. But, those hallways were extremely long sections, angled and set to each other to make for different feels and looks.

Interesting you should mention this… a recent (this week?) Entertainment Weekly has an article on the “Desperate Housewives” street, and apparently it’s the same street that you mention above, with one of the housewives living in the re-done Munsters house.

And isn’t that the same street that Major Nelson and Jeannie lived on?
Or if you pass through Covington, Georgia, you’ll see the town they used for location shots at the begining of the show. 
And if you pass through the park in Jasper, Georgia, you’ll see the water tower from “The War.” It was purchased from a local quarry, disassembled, moved to filming location, filmed, disassembled, donated to the city of Jasper and reassembled in the park. Walking by it on the jogging trail one day, I noticed something looked amiss. One of the rivet joints on one of the cross beams looked odd. I toom a closer look and noticed it and like a dozen others were just wood and plastic painted to look like rusted metal and glued onto the steel beams which were one whole piece. I guess it didn’t look “industrial” enough.

A friend of mine in New York City got the old Merv Griffin set, and set it up in his apartment. Then everytime we went to visit him we had to talk to him like we were on a talk show.
