Is anyone out there familiar with ADA accessory rules and regs?

IMO the most cost-effective parts of a kitchen or bath reno, that you could pay yourself in labor vs. pay a contractor would be 1) careful demo and cleanup, 2) painting or skimcoating, 3) re-using existing materials/accessories or using refurbished ones in a clever way (e.g. re-use existing cabinets and painting them)

The owner may reside in either the remaining portion of the structure or the newly created junior accessory dwelling unit.

In my rental agreement (lawyer reviewed and approved) it specifically says no smoking or vaping within 20ft of the building and all butts must be left in a coffee can with sand in the bottom and one is already provided in the "smoking area".Explanations are given for allergies, health, and second hand smoke etc. etc.I've not had any issues yet.

Tucson, Arizona, presents a promising market for real estate investment, especially with the recent adoption of the by-right ADU (Accessory Dwelling Unit) ordinance.

In California, diverse housing options are encouraged, including Accessory Dwelling Units (ADUs), reflecting a broader trend toward inclusivity.

I didn’t smoke or vape when I rented from my landlord who has a no smoking policy for his units and property.

Our City allows you to build what they call Accessory Dwelling Units in backyards!
