Wife is an architect and I think a lot of people don't have the kind of funds to put into an ADU/MIL plus if the lot can even fit it, etc... conversions are common but personally I'd just look to buy one that already has the ADU/MIL on it versus dealing with GCs and such right now, market is nuts with labor and materials.

The process for my county was pretty straight forward, just needed to include before and (proposed) after drawings (which were hand drawn, no architect needed) showing the 2 walls and electrical outlets/switches.

I have left the field and recently starting working as an assistant for a prominent Orange County real estate agent.  

Other notes: - This will likely be setup as a 506(b) or 506(c) - Land/Lot is already secured and currently aligning an architect for design.- Goal is to have property built & ready for use / short term rentals by Spring 2026. - Location is Central Wisconsin in an up & coming vacation area. 

Again, it's best to check with the Houston Permitting Center and/or the city's Planning Department to determine the specific regulations that apply to your property.Overall, the process of converting a detached garage into an ADU in Houston, Texas, can be complex and may require the assistance of professionals such as architects, contractors, and attorneys.

A GC is not an architect or designer.

Here are some numbers from 2016 project, I purchased a house in Melbourne for $420k and got designs for 3 townhomes cost $20k, just employed architect and onsold in 12 months for $850k to a builder/contractorThe trick with this one is the builder/contractor must have 20% net profit and the designs must be very good and what the market dictates otherwise it wont sell Australian property market in general is now in decline.

The owners and architect worked closely with the city's building dept. to do everything to code or have the code adjust to them. 

I see requests for CPAs weekly in the forums so it seems like they would want to highlight that section more prominently to cut down on the repeat questions

Aside from wanting to invest in real estate, I am an architect and landscape architect.
