Im looking at the code and the legality of tiny homes.You dont need a permit to build a one-story detached accessory buildings used as tool and storage sheds, playhouses and similar uses, provided the gross floor area does not exceed a set amount of square feet, the plate height does not exceed a set feet in height above the grade plane at any point, and the maximum roof projection does not exceed certain amount of inches.

Arlington states short term rentals are "Accessory homestay permits allow residents to host overnight guests for stays of less than 30 days in residential dwelling units that they reside in as their primary residence."

There are a lot of factors that go into that.On the vast majority of properties you'll only be able to operate with an accessory permit, which requires a homestead exemption.

For those of you who've either built an accessory dwelling unit (ADU) and then sold, or have experience buying a property with an ADU, did those properties see a good ROI? 

All of the accessory businesses crop up to help support the industry. 

You can probably buy a single family and build a Detached accessory dwelling unit (DADU) in backyard.If you have experience and can finance 30–40% of project through a construction loan, you can go big as long as zoning allows, and numbers make sense

The zoning is technically a SFH with an Accessory Dwelling Unit.

Purchase price: $300,000 Cash invested: $300,000 We built an Accessory Dwelling Unit (ADU) in our backyard.

Here's a brief overview of my situation:Project Details: I've purchased a single-family home in January and plan to build 6 accessory dwelling units (ADUs) on the property.

In other words, the real estate does not include the additional parts of most str businesses, like furnishings, accessories, going concerns of a business, and the other costs associated with this type of business.So, it is good to be clear on what value is being referred to, RE or str Business.
