Assuming a building footprint of up to 5000 sq ft, use could not support the need for a lot of parking (probably <20 spaces).Not interested in auto maintenance and other uses that require disposal (and potential runoff/dumping) of large volume of hazardous materials.Long term, I'd prefer something that contributes to the improvement of this area (e.g. a used car lot might be OK for a couple of years just to generate income, but I'd want to find something more beneficial after that).

All of the meetings that I see about ADUs are sponsored by builders who want to sell their ADUs.Are there others who want to build their own or want to share their experiences about building ADUs / converting outbuilding / navigating codes in Portland that DO NOT involve hiring one of these tiny house start-up companies?

Located in suburbs outside of Seattle, new to investing and trying to figure out the best way to grow and build wealth and learn what others are doing.

Some contractors can remodel a kitchen and put in flooring/paint, and some can build ground up.

Currently, we own 3 lots and are in the process of building the first single-family rental which should be done by summer.

If the building is still a modular and not real estate, that could be a big factor. 

It is a pre-existing multi-family building in a commercial(C-3 Zone).

Mid-term Rentals: Utilize platforms like Furnished Finder for still higher rental income potential but less management than a nightly rental requires.Commercial Real Estate: Explore opportunities in office buildings, retail spaces, or industrial properties for potentially higher returns.

Regardless of major you need to spend time building a real estate investment education.
