This topic is the place to be if you're looking for a sweet new pad to call your own. If you have a location to contribute, please do so. And please do not post modded houses.
A house needs to have
?a bed
?storage
?amenities (not necessary)
?shelter(obviously)

Here's the list:
Megaton Home
Tenpenny Tower Suite
those are the main homes in the game.
Other "incidental housing":
The houses below aren't technically ownable, but the player can still live at these sites:

Nearest Map Marker Secure Containers (Specify Which) # of Beds Workbench? Free of Enemies? Notes / Features
Abandoned car fort 6 ammunition boxes (5 next to the bed, 1 behind the sandbag barricade) 1 no no
Alexandria Arms, Ruined Building 1 ammunition box, 2 filing cabinets, 1 fire hose box, 1 footlocker, 1 gun cabinet, 1 Nuka-Cola machine, 1 refrigerator, 6 safe boxes. 1 yes no
Building directly SW of Alexandria Arms.
Nice 3rd floor view.
A couple of bear traps can be reactivated, although it doesn't seem necessary.
Andale, Old Man Harris' house 2 cabinets, 1 corpse (Old Man Harris), 1 footlocker, 1 oven, 1 refrigerator. 0 no no
The bed is owned by Old Man Harris and cannot be used; however the nearby concrete treehouse has a usable bed (may require the scavenger to be dead), and the sinks in the Smith and Wilson homes restore 30hps while only giving 2 rads.
Easy access to daily strange meat pies, and membership in a true community of cannibals (rather than joining The Family).
The kitchen has a bit of counter space, enough to display Old Man Harris' corpse in a similar fashion to those in the shed or basemant.
If you're unable to kill Old Man Harris quickly he may flee outside, preventing his corpse from being used as decoration or a storage container.
No one from Andale will enter the house; however, the children will take up residence here if their parents are killed (either by the Lone Wanderer or other enemies).
Junior Smith and Jenny Wilson make excellent stand-ins for the Pint-Sized Slasher if given the masks located in Point Lookout and a knife through reverse pickpocketing.
Arefu, West residence - 2 no yes
Ian West will continue to live here.
After completion of Blood Ties, residents of Arefu will give gifts or provide services.

Bittercup will give you a small, random gift every 13 hours if you make a good first impression.
If Broken Steel is installed several residents of the town may be discovered dead upon an overland return, and the Lone Wanderer may be attacked as well by an albino radscorpion.
The town can become equipped with small guns for it's residents, a minefield, robots (sentry bot, protectron) or the residents can be taught how to hide from trouble depending on choices during Big Trouble in Big Town.
Residents may steal items, or pick them up if left out as decoration.
