This can be a pretty large cost if 1) the ADU is very far from the street or 2) you have to cut into a concrete driveway to run the sewer (and then patch the concrete).

Also, you can only deduct losses against regular income if you are actively managing your property (no concrete definition, but you have to be the decision maker, not necessarily swinging a hammer) or you are a real estate professional (working over 750 hours a year in RE).Example:W-2 income $95,000Rental property Rental income $13,000Taxes $3,000Maintenance $2,000Mortgage interest $5,000Depreciation $7,000Rental loss that I report to the IRS on Schedule E: $-4,000 ($13,000-$3,000-$2,000-$5,000-$7,000)So when I do my taxes, I get to tell the IRS I made $91,000 instead of $95,000.

Also some jurisdictions when you go to more than 2 units make you build a concrete block wall around your furnace and water heater.

For bedroom egress it it often requires putting in window wells which requires cutting large holes in the concrete walls.

I've even called the county office when I couldn't find any concrete ruling to ask what their opinions were on short term rentals and it's been very helpful.I agree with Peter about checking Airdna for initial analysis.
