Wondering how many doors my home should have.
By code 2 is a must the obvouis FRONT and BACK doors for proper Egress from the home and each door must have a Landing of 3x3 or greater. But beyond code and additional doors would be personal preferance.You may want doors off the Master Suite that leads to a deck or other Outdoor living spaces.
Minimal two doors per home, but if you have a finished basement you need one door or a one E-gress window.
Each inside room must have one of course. Doors to outside? idk how your house look like but I recomend 3. front , backyard and one to side of house. This is the “Dirty door” the one you use to get the garbage out, or let the dog and kids use when coming from playing. If you have one in the Garage that counts too.
The point is your front door and rugs don’t get so dirty and damaged faster by all the dirty shoes or stains.
of course all depends on your house layout 
At least two.Front and back door.
front entry
rear
garage ??? is it a door , really, yes
garage personal door…is a personal thing
then one on each bedroom and bathroom
by code a house should have 2 doors a front and a back you could add a few more if you would like
Chapter 10 (Means of Egress) of the International Building Code has thorough definitions. Codes require egress doors to meet minimum dimensions and standards. Check local building codes for further requirements.
This is a question that get asked quite often and many people are surprised to find out there is only one required exit door in a single family home per the IRC. However, there are requirements this door must meet. It must be a side hinged door, a minimum size of 3 feet wide and 6 feet 8 inches tall. So that sliding door, NOPE it doesn’t meet building code for an exit door. You can install them, but you must have at least one side hinged door to be code compliant. This width and height is a normal stock size exterior door. So there is nothing special about installing an exit door.
There are other egress requirements in your home including but not limited to egress window sizes. When all these requirements are used together, a safe exiting of a home is not faulted by only one exit door.

At least 2, but preferably 3 or 4.
As many as you need or want, in addition to those required by code.
Means of Egress require two doors. That is the minimum number acceptable for a house. There are also codes for states in what dimensions the doors are required to be.
Should have or need to have? Single family residence needs only one but lots of caveats.
As many doors as you need.
Two door and then use your common sense to create a beautiful space.
that really depends on the size of the house but at least two
IRC is pretty simple, make sure your local jurisdiction does not have any ordinances or other adopted codes.
Egress door. Not less than one egress door shall be
provided for each dwelling unit. The egress door shall be
side-hinged, and shall provide a clear width of not less than
32 inches (813 mm) where measured between the face of the
door and the stop, with the door open 90 degrees
Good Morning,
2 exits are required, different states have their own egress codes. You can have as many doors as you’d like, as long as you are meeting code for your state. I would keep in mind energy conservation as well.
