If your plan is to sell the house within the next 7-ish years, then keep that in mind when designing your ADU.  

I have been working for major companies for my career so far doing engineering design, equipment and property maintenance, assessments, repairs, contract management, construction management and much more.

But just for my confirmation, you do understand where I am coming from right?

I'm sure that's by design considering the cost of this guy's upcoming seminar. 

Hi Mark,I used your spreadsheet design to do a quick analysis of a property in my area.  

Here are two of my favorite lease clauses that should help you. a.Landlord informs the Tenant that the sewer system of the Premises is not designed to accept many types of items, included but not limited to, paper diapers, sanitary napkins, tampons, and children’s toys, balls of hair, grease, oil, table scraps, clothing, rags, sand, dirt, rocks or newspaper.

Infact one has got a myriad of designs and styles to choose which meets your requirements.

A couple of days ago, I saw a blog post at BiggerPockets.com by coincidence and signed up the membership for curiosity - maybe because I haven't seen any Canada-based online forums designed for RE investors yet.

I also look forward to offering any advice or feedback in areas of home renovation, design and function, where I am knowledgable.

I'm looking for advice on how to possibly design our deal.
