Is your backyard big enough for a beehive or two? A typical sized city lot of about a tenth of an acre or so, even one as large as large as a half acre can accommodate one or maybe two colonies when there are other space considerations -- like a family that uses the backyard for recreational play, cookouts, family pets or a flower or vegetable garden.
Do your zoning regulations permit bees where you live? Check before you go further because you may be violating some local ordinance or other and the zoning police frown on citizens breaking these taboos.
And of course your family needs to sign off on this enterprise. Your spouse, kids, pets … all need to know that bees will be around. Is anyone allergic the sting of a honey bee? A tiny percent of the population is you know (just like peanuts, shellfish or horseradish) … maybe you are and don't know it. If you don't know … say, from a previous experience, get tested by a family doctor. Emergency room trips are scary, and expensive.
