Your first task as a Mayor will be to lay the foundation for Sims to live and work and, as you may know, a city isn’t a city without buildings!
These are the three essential buildings
Residential (Where your sims live)
Factories (Industry) (Where you create resource materials)
Stores (Commercial) (Where you create store materials from resources produced at your factories and other stores)
Lastly, these miscellaneous buildings unlock as you level and serve unique purposes
Miscellaneous (buildings that lie outside your city limits that you can upgrade and use)
