The numbers above are construction costs, but they don’t include architectural plans and city permits & plan check fees (approx.. $10,000-$15,000) Studio (0 bedrooms): 300-400 square feet (sf) (most likely a garage conversion):According to MLS info, in the past year, the rental rates of studio units were $1,200 for ADUs in lower-cost areas and up to $2,500 on the high end for ADUs in portions of LA like Venice and West Los Angeles. 

I’ve been practicing architecture in Tucson and the surrounding areas for the past 10+ years.  

It is incredibly landscaped, the architecture is steeped in an Italian coast concept, and a home is attached in the same style on the property.

Let alone the 10 weeks it takes for architectural drawings.Columbus OH is a great place to look! 

You'll need architecture drawings/blueprints, etc. and a compelling reason your request should be approved.

I thought I would give it a try and see what discussion will arise from a topic that is not common to this forum.As an Architectural Engineer that lives and breathes construction, I would like to see if investors know much about sustainability as a building practice.

I'm all in for around $160k with purchase, rehab, holding, financing, architecture, etc. and it's rented at $1500/month.

Unless you need to preserve the historical architecture, you should consider converting the roof or get on the wait list to repair it.

Besides the architecture/construction considerations (building code, finding a contractor that know how to work with containers, etc), does anyone has any experience with these, specifically in terms of financing and insurance? 

Zoning petitions, architectural challenges, contractors, etc.
