You're right. Pigeon droppings can pose human health risks, primarily by inhaling spores from a soil-borne fungus that grows where droppings accumulate. Because spores are inhaled when airborne, wet (fresh) droppings do not support the growth of this fungus.
If a significant amount of droppings have accumulated, removal is best left to the professionals. The safest advice I can give you is to contact your local public health department for information on proper clean up and disposal guidelines.
Because the droppings are located right out your front door, ask about your rights as a tenant to request that your landlord minimize your exposure to this health risk. I'm not suggesting you become involved in a conflict with your landlord, but rather that there may be local resources available to help both you and your landlord deal with the problem.
Pigeons are difficult to control, especially in urban environments where they have an easier time locating food sources.
The most effective methods usually include physically modifying the surface of the structure they prefer to roost on. Wire screens, netting, sheet metal or other materials can be constructed in such a way as to deter them (think vertical prongs or prickling fences). Pigeons prefer resting on relatively flat surfaces, so modifications should be created to make angles of 60 degrees or more.
There are also non-toxic sticky substances designed as tactile bird repellants that may be applied directly to perching areas.
Less radical (and less effective) methods suited to urban environments include using combinations of visual and auditory devices like shiny strips of Mylar tape, helium filled eyespot balloons, decoys (like the owl) or wind chimes.
Just till the droppings into the soil. They make wonderful fertilizer for leafy green plants, and they will break down into a harmless substance that is very good for the soil. One of my college professors said their gardener used chicken droppings around the roses, and they were out of this world!

I have just moved into a beautiful brand new apartment building and I'm on the top floor. The only thing that wasn't beautiful was the balcony. It was totally covered with pigeons and their poop. A friend told me to spray straight javex bleach on the railing or wrap the railing in plastic and generously spray with bleach. It worked! All in one day like a miracle!
Something else that is effective is using a slinky (the childs toy) and attach it to railings or window sills. The pigeons can't perch.
