Sometimes the numbers are great, sometimes it makes more sense to keep it as accessory space and focus on improvements to the existing duplex.If you want, message me privately with the municipality, address, a few photos, and basic attic dimensions, ceiling heights, stair details, and window sizes.

Most lenders will look at that as a small commercial use since the income is short term and more like events than a standard lease, so a straight residential rehab loan can be tough unless it stays accessory and you are not changing the use much.

There's an accessory ADU in the backyard 3817 English Ave, but I don't see how it got approved.

I’m intentionally pressure-testing the structure before committing further.The deal involves a 31×110 infill lot (~3,400 sq ft)zoned to allow a duplex by right, with an overlay that may support an accessory dwelling unit (ADU).

I’ve owned and underwritten a few deals like this, and the short answer is: what matters isn’t how you think of it, it’s how the city, lender, and insurer classify it.A detached garage converted into a store pushes this firmly into true mixed-use, not residential with an accessory structure, unless it’s fully permitted and zoned that way.A few things to verify before you get excited about the numbers:• Zoning and permits – Is the commercial use legal, non-conforming, or outright illegal?

Adding a few tasteful accessories to the tables could add extra warmth and charm—perhaps a trusted friend with a great eye for decor could help brainstorm some ideas.

Covering data from 2013 to 2023, the analysis (Trends in Median Appraised Value for Properties With Accessory Dwelling Units in California) offers one of the first long-term looks at how ADUs influence property values over time.According to the same FHFA study, about 3% of appraisals included an ADU – up 100% from just 7 years earlier.

Being intentional with design — putting money to the side to pay a professional designer, buy furniture and accessories — can be all the difference in a 5 star listing or a 2 star listing.

One key restriction: Accessory Dwelling Units (ADUs) are not allowed for STR use in the county. 

Long story short, I added an AADU (attached accessory dwelling unit) onto the house, but I haven’t been able to refinance it yet.
