Basically the question says it all. I'm asking this because I keep getting a lot of ngons and tris with the model I'm working on. And I plan on letting people use this model for whatever they want(whether it be mods or animations) and I don't want it to be filled with ngons and tris.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
What has worked best for me so far is to (A) start with quad-based meshes, such as cubes, UV spheres, and cylinders and then (B) add new geometry by using loop cuts (Ctrl+R) and extruding faces (E) in edit mode.
You can then move vertices manually in edit mode or use sculpt mode (with Dyntopo off) to shape your model without adding vertices or creating ngons.
