ADU close the freeway

[Surendran Palanimuthu]

Hi, 

I would like to get some insights on building an detached ADU 500sqft (maybe a one bedroom or small 2bed/1ba). our backyard is facing the freeway. Im planning to do this adu project, mainly for the rental purpose. This house is in north sanjose, close to 680. I have been talking to contractors and some prefab companies. there is also another option to have an junior attached adu (300sqft) with small addition for bathroom/kitchen. this would cost around ~80K.

1. Detached adu will be more closer to the freeway than attached adu. risk of renting more days because it is close to freeway ?

2. Detached will be more spacious than attached. so, more rent, with financing, number are good with detached adu.

I would like to hear your thoughts.

Thanks
