Buying land and developing new multi-unit building

[Sam Kasa]

Hi - I currently rent two single family homes in Overland Park area. I am now interested in buying land and developing new 4-Plex units. Depending on the cost, I would like to start with 2 units and later build more as the space/budget allows. What are some of the things that I would need to consider before heading out to buy the land? Are there City ordinances/zoning laws that can keep me from building multiplex units? If you have any experience with this, any advice is very much appreciated. Thank you!!
