Anyone familiar with permit timelines for converting rooms into bedrooms and bathrooms?

I’m looking into alternative methods to house having and MFH run for $700k+ out here.At the moment, I live in a detached garage converted into a 600sf 1bd/1bth.Since the 700k price point for a duplex with max 3bd/2bth unit to rent it out of question for me, I was thinking of the possibility of picking up a smaller house with the possibility of converting a garage or building a separate addition that my wife and I would then be able to live in while renting the main house.I know CA is becoming very favorable towards ADU’s now a days and was wondering on if this could qualify as a primary residence for myself as well as me be able to use potential rental income for me to be able to qualify for a loan.Still new to BP and REI, I couldn’t find a google answer on this, so any help would be appreciated.Thanks!

The .5 bath has been converted into a complete bath without permit.

Hello Everyone,I am absolutely fascinated with multi-family real estate, specifically the idea of converting inactive hotels/motels into affordable living spaces to buy and hold.

Mine is a garage conversion, which is being converted to 350 sq feet of living space. 

In Baltimore Many SFHs have been converted to Multi family.

@Robert Hugs you don't have to refi out of the fha when you convert the property to a rental a few years down the road.  

One strategy a BP member discussed was to purchase below-market duplexes with tenants, completely remove the property from the rental market (Ellis act eviction) and then convert the duplex into a SFR and flip the home.If someone was out there tenant-flipping properties, they'd probably have a good client base (assuming the flipper isn't overcharging for the property).

I have owned a few rental properties (mostly primary residences converted into rentals).

Because unless his gains are higher than 500K, converting it to a rental as a tax strategy is terrible advice.
