ADU query - San Jose, CA

[Rishabh Mathur]

Hello,

Hope you are all doing well. I was wondering if the BP community here could help us with my ADU queries. Greatly appreciate your time and perspective in advance.

We are planning to build a 2 Bed/2 Bath 750-1000 sq ft detached ADU. Our lot size is 7300 sq ft and main house is 1700+ sq ft.

Location: San Jose, CA

• - We were thinking to potentially design the ADU such that we could have a wall (or a door) that allows us to separate the ADU into a 1 bed/1bath for self use (or rental) and another part which could be rented separately on AirBnB as needed. In future we could also rent out the main house that we currently live in. Is there a legal limit on how many rental units/tenants we could have on one single family lot?
• - Is there a cost/ROI benefit of a 2 floor ADU plan vs single floor vs Loft ADU floor plan?
• - What are some best practices we should keep in mind to keep maintenance cost of the ADU to the minimum in the long run?
• - Is there a real benefit if the ADU is under 750 sq ft? In San Jose I think that lowers the school fees cost/taxes etc. Is that even a significant cost in the long run that we should take into consideration?
• - Any other best practices that you could share that could help maximizing the rental yield, reducing prop tax and construction cost?
• - We are currently zoned as R1-8. What's the process to split the lot into 2 parcels in San Jose? Is that doable and worth exploring further?
