For the purposes of spells such as locate, does a building count as an object? If not, why not? What constitutes an object? What about a magic item with the Structure trait? Are the constituent parts of a building (e.g. doors, windows, staircases) objects?
Is a plant an object? What if it's in a pot (and therefore mobile)? Statues seem like they're inarguably objects, but what about a carved stone column, or a fountain?
To me, the term "object" is ambiguous and requires clarification.
Please and thank you

What constitutes as an object is whatever the GM deems it so within reason
applying common sense usually works but lets go for your examples
a plant could be consideren and object, but certainly not an *inanimate object* sometimes that is a diffence, it depends on what you want to do with it
statues, columns, fountains are not exactly natural features and certainly no lifeforms, so I would argue they are objects
going from that, size is not a limited to an object, it would be logical to rule that everything that is not purely landscape and not alive is an object, this would make a house an object in at the least most contexts

It's going to be a GM call
For example, here's the Locate spell you're referencing
Locate Spell 3
Uncommon Detection Divination
Source Core Rulebook pg. 348 4.0
Traditions arcane, divine, occult
Cast 10 minutes (material, somatic, verbal)
Range 500 feet; Targets 1 specific object or type of object
Duration sustainedYou learn the direction to the target (if you picked a specific object, such as “my mother's sword”) or the nearest target (if you picked a type of object, such as “swords”). If the target is a specific object, you must have observed it directly with your own senses. If it's a type of object, you still need to have an accurate mental image of the type of object. If there's lead or running water between you and the target, this spell can't locate the object. This means you might find a type of object farther away if the nearest one is behind lead or running water.
You spend 10 minutes trying to locate an 'object' that you have observed directly with your own senses and is no more than 500 feet away from you.
Even after those 10 minutes, you only know what direction to move in. You don't know exactly where it is. You might even be able to see the building without the spell even if there's a stream between you and the building. But you wouldn't be able to locate it with the spell.
Context is everything. I'd ajudicate your use of the spell differently if you were trying to find a building in a fog, or a casket of jewels in a castle. There's not going to be a less ambiguous definition of "object" if the designers want the spell to work in both instances.

GM Discretion
As others have stated, this is in the realm of GM adjudication as the term Object is not explicitly defined, so expect results to vary; however...
You repeatedly cast the same spell while moving at half speed. Typically, this spell is a cantrip that you want to have in effect in the event a combat breaks out, and it must be one you can cast in 2 actions or fewer. In order to prevent fatigue due to repeated casting, you’ll likely use this activity only when something out of the ordinary occurs.
You can instead use this activity to continue Sustaining a Spell or Activation with a sustained duration. Most such spells or item effects can be sustained for 10 minutes, though some specify they can be sustained for a different duration.
Even if a GM were so kind as to allows the player to Target an entire building, the party would need to find it in 10 minutes or less.
Adjudication and Supporting Rules
The closest I have found to an explicit definition is the Animate Object Ritual
which has Targets: 1 Object and the ritual description provides some examples.
So using Animate Object as a guideline, it appears (my interpretation of the RAI) as the level of the ritual goes up, so too does the size of Object you can choose as a viable Target.
Using Bulk rules of creatures gives:
Rank 2 Ritual - Can Target a Large 2x2 Silverware Swarm - Bulk 12
Rank 5 Ritual - Can Target a Huge 3x3 Statue - Bulk 24
Rank 8 Ritual - Can Target a Gargantuan 4x4 Trebuchet - Bulk 48
Since this is a Ritual, my opinion is that using these numbers are actually fairly generous if you were to apply them to spells. Or at the very least, my opinion is that to Target larger Objects requires the use of a more powerful resource - such as a higher Rank spell slot.
Under these parameters, a expansive building would be beyond the scope of a Rank 3 Locate spell. Perhaps a small hut, though. Other objects that fall within the bulk parameters given the spell Rank would also qualify.

Yes, that is actually a good observation to bring up. The building also needs to be within 500 feet. So if finding a building within that distance is a problem, it is likely that finding it within the time limit may also be a problem.
