please advise  SB68 states “Require a permitted junior accessory dwelling unit to be constructed within the walls of the proposed or existing single-family residence.”.  

The notion of permitting ADUs was introduced in 2018 by Lightfoot’s predecessor, Rahm Emanuel, as a way to spur creation of new affordable housing options in increasingly expensive neighborhoods, particularly those where single-family homes predominate.Osterman said ADUs are a way to “create more housing options” that may suit single people, young adults returning to live with their parents, and retirees.While his proposal had been scheduled to go up for a vote July 21, Osterman said it'll be postponed after several aldermen expressed strong opposition at a hearing Friday that lasted more than three hours.

There are also some mapping related options that can increase your density further without triggering additional reviews on the actual development proposal. 

They've asked me to propose a partnership structure.  

Some will propose solutions but at the end of the day that isn't what they are hired to do. 

The costs can vary dramatically depending on how much needs to be done to get those items near your proposed new hookup.

I would propose that a relationship that can't endure some temporary separation is a pretty weak relationship. 

A comparable sale is a property that is within 30 years of the age of our proposed purchase, within 200 square feet, the same style, lesser or equal bedroom count, lesser or equal bathroom count and similar acreage.

So as you were proposing, the JR ADU can be an attached garage and there can be a regular, detached, ADU up to a max of 1200sq ft?  

I have met a number of proposed contractors this way because people leasing properties are sometimes prepared to carry out their own tenant improvement at a very favourable price.
