As far as I know, marijuana is not allowed outside, medicinal or not.As to whether or not it's allowed inside, I think the laws/bills that allow for people to carry it/use it inside for medicinal purposes will give the users legal ammo to use against landlords.

It also appears to offer true integration with Google Contacts and Calendar which Insightly, Podio and Zoho don't do (or at least not very well).  

He is growing for medicinal purposes. caregivers grow for others who need mmj.

I am sure it can and is done regularly, but it is a gray area and must be handled with care and integrity. 

1) Clean up the plaster and paint2) New sink vanity with cabinet (hides the trash can) get rid of small table3) Replace painted tile on walls4) mount toilet paper holder on wall5) Clean / scrape window glass6) Hang decorative mirror over new vanity7) install medicine cabinet in left wall if there is room

Is it the separate sprayer wand or is it an integral pull-out sprayer?

The legal grey areas come up with when actual medicinal users in California have a large amount of marijuana with them (sometimes a year's worth just after harvest), are growing it, or are suspected of trafficking in it.

If that buyer is an investor and he wants to keep his integrity and reputation, then he shouldn't go around you....

Cracks are maybe half a centimenter wide at worst points.There also appears to be some integrity issues outside.  

I'm afraid it might compromise integrity of structure.
