Trying to build an ADU in CA

[BSdetect]

After many months of searching i find that most of the costs are getting the ADU installed on your land.

So if a plan / design / model is quoted at $80000 you can expect to pay double to get it built and fully permitted.

This sort of price is for a mere few hundred sf. Not a lot of space at all.

Recently we looked at a two bedroom manufactured home for $100,000

Then they explain all the extra costs ending up at $180,000 to $200,000

The only way to do this with reason is to handle all the building and other work yourself (using subcontractors).

Of course expect to pay more property tax as well.

We do not want any RV or Tiny House type dwelling so no need to make that suggestion.

Thanks.

1. Key piece of info missing

ADU = Accessory (or Additional) Dwelling Unit

2. Another key piece of info missing

What is the purpose?

Will someone live autonomously in it? Or will they be coming and going into the house?

Rental? Air BnB? Helping solve under-housed-person crisis? Stash grandma into it?

Sorry I don't have any experience or knowledge on this, but clarification may help others help you.

6. The adu is purely for our daughter to live in full time.

4. Some jurisdictions in California have streamlined the process...

... others are dragging their feet.

Our city has fully embraced the ADU concept and has a set of pre-approved plans you can choose from. Tick all the boxes, choose your plan, and supposedly you are good to go.

Here's the state handbook, if you don't have it already:

But the reality is that most people in our city deal with the housing shortage the old fashioned way with extended families living under one roof -- grandparents, siblings, cousins, etc..
