Many kinds of civil cases cannot include lawyer's fees and in your state that apparently includes this type.

Are there any other min requirements that I should include?

Also make sure you understand everything about adding an ADU including value of the ADYPU, financing, impact from rent control, duration between initial expense and initial income, true cash flow (know the 50% rule, at 50% rent ratio initial property tax will be near 20% of income)- educate.  

When a husband and wife jointly own a residence, and the husband takes out a Home Equity Line of Credit (HELOC) in his name only, the spouse's involvement and liability can vary based on several factors, including state laws and the lender's requirements.1.

That said, I have a nice stream of passive income (including math freelance jobs to keep me busy), and a lot of time on my hands, as well as experience with materials and vendors doing home renovations.

Look for one that includes a training video to ensure you understand how to best use it.

If you’re a business owner with no employees or only part-time employees working less than 1,000 hours per year, you could set up a solo 401(k) and contribute up to $69,000, which includes both employee and employer contributions.

A lot of them charge much higher and include extra "material" but if my experience tells m anything, you won't need that. 

@Taylor RobertsonSome buyer agreements include language for situations like this.

I would definitely accept a $3,000 quote to paint my whole interior, especially if that included the cost of materials.
