So the places we all encounter that don't even have a wheelchair ramp at the entrance (at the appropriate incline, etc), even though it would be relatively easy to put in, aren't compliant (envision a storefront set back 10 feet from the sidewalk).

Asking about the SW suburbs specifically, in the land of long sidewalks and big actual parking lots. 

I have a city rowhouse with a 20' sidewalk and 5' wide steps with 9 treads and two 7'x7' landings.

Also, if you're familiar with Chicago, it's your standard 6-unit building, so imagine the sidewalk surrounding it. 

Once that’s confirmed, they’ll help you submit the required permits to the Department of Buildings (DOB) and get approval from the Department of Transportation (DOT), since it affects the sidewalk and street.After permits are approved, you’ll need a licensed contractor to do the construction.

When it comes to real estate, here's a general list of eligible assets and their depreciable lifespans that you should know: Residential Rental Property = 27.5 yearsThis includes any building or structure where 80% or more of its gross rental income is from residential units.That means:- Apartment buildings- Single-family rental homes- Duplexes, triplexes, and quadplexes- Mobile homes (used for residential rental)- Any kind of residential lodging facility where the primary purpose is long-term rentalCommercial Property = 39 yearsThis includes non-residential properties like:-Office buildings-Retail stores and shopping centers-Warehouses-Industrial complexes-Hotels and motels that do not qualify as residential rental propertyLand Improvements = 15 yearsThese include sidewalks, roads, fencing, some landscaping, and parking lots that are separate from the building.Personal Property = 5 or 7 yearsPersonal property used in a rental activity usually has a 5 or 7-year life.This includes most furniture, appliances, carpeting and various machinery.Qualified Improvement Property (QIP) = 15 yearsGenerally, this includes any improvements made to the interior of a non-residential building after the building was placed in service, excluding elevators, enlargements, and the internal structural framework.Computers and Related Peripheral Equipment = 5 yearsVehicles = 5 yearsNote that the land itself is not depreciable.

You can expect that you will be required to build roads, sidewalks, storm water control, utility taps, street lights, street trees as well as recreation fees as part of the development process. 

But it's also true that this had been open space provided to the community for the better part of a century and now it was fenced off with not even a path or sidewalks around most of the perimeter. 5.

Non-tangible property includes buildings, land or other inherently permanent structures.I get a lot of questions on which group specific assets belong in, so I put together a list to help.Non-Tangible PropertyBuilding (27.5 or 39 Year Useful Life)Land (Non-Depreciable)Paved Parking Areas (15 Year useful life)Swimming Pools (15 Year useful life)Fences (15 year useful life)Bridges (15 year useful life)Exterior Landscaping (15 year useful life)Docks (15 year useful life)Sidewalks (15 year useful life)Tangible Personal PropertyMillwork or decorative trimCarpetAir Conditioning equipmentShelving, cabinets and display racksAccordion doors and partitionsWall coveringsInterior landscapingNeon or other signsDecorative and business specific activity light fixturesGenerators, machinery and kitchen equipmentWindow treatmentsWhat other questions do you have regarding cost segregation?

Learn the eviction procedure for your area, perhaps contact a lawyer in the field to help you with this one, and get the fraudster you're currently housing out on the sidewalk to sleep in a cardboard box where they belong.You're going to lose plenty of money here, but this will never happen to you again, and you can minimize your losses if you move as quickly as possible.
