Where is your addition  architect/engineer when this condition came up at the existing home? 

We went with the latter, which gave us the opportunity to design and build our first house pretty early in our careers (most architects and designers don't get to live in their own designed home.)

I'm a licensed architect with my own LLC and have house-hacked in the past; so I have working knowledge of the process, but not the start-up.

@Micah Haworth @Bradley EischensHi Micah,To piggyback off of Brad on construction costs, I am an architect here in Minneapolis. 

Can anyone suggest an architect or if we need a GC with a license? 

@Balaji Devendran A garage conversion to ADU in Orange County is running between $90-150k right now.A new ADU above a garage is more expensive...probably around $450-500/sf.In order to determine how many ADUs you can build on your property, you need to either go to your City's Building/Planning Department and ask them or find a local architect/designer who knows the city's ADU guidelines.If you want to DM me...I can provide you an ADU resource guide for all OC cities and some OC contractor recommendations. 

You will need architect and attorney who do condo offering plans, and a capable contractor to do your renovation.

We have already looked at the county and preapproved plans and one actually might work perfectly for the space and just needs an architect to review and do the site plan, Title 24, etc....We have talked to the county and are under County Jurisdiction, and have plenty of room for the ADU in a newly excavated part of the property.

Good day, I hope this is posted in the right forum and I can really get some positive and perhaps local feedback.So company says I need an architect to do the drawing and submit to county to raise a portion of the roof by 2 block height.
