Have you ever looked into adding a garage apt / accessory dwelling unit where a historic garage once stood?  

The city of Grand Junction and our county have generous rules regarding "ADUs" (accessory dwelling unit).

Seeing as this is the New Construction forum and a lot of the questions are some version of “how much does it cost to build X” I thought I would share some real numbers and experience from a project we currently have under construction.This project is an Accessory Dwelling - 720 sqft with one bedroom, one bathroom, a living room, kitchen and small laundry room plus a screened porch.

Hi All,I'm new to this forum so here's a bit of background on myself: I'm a young, new real estate investor that currently owns 1 residential investment property (it has 1 main house and 2 accessory dwelling units in the back, so 3 units total.

As homeowner you may be able to have an accessory  unit, in basement if it meets code.

Let's say, all missing accessories in 2015 would cost $150.

The income on the listing says they are getting $1,100  for the accessory dwelling unit so I am unsure how your expected income is $2,200?

Friends in Ithaca recently added an accessory dwelling unit when reconstructing the garage at their SFR in Ithaca and the process has taken well over a year navigating the city bureaucracy - with a couple of construction starts and stops because neighbors complained (spuriously) to the code office. 

It also allows the urbanhouse, detached accessory dwelling unit, duplex, and tandem house building forms."

That will help narrow down what type of accessorial charges you can have.
