What is the Best ADU Size to Build in El Cajon (Zip Code 92020)?

[Taha Tekreeti]

Hi everyone,

I’m in the process of closing on a property in El Cajon (zip code 92020) with RM2200 zoning and enough space to add ADUs. I’m trying to decide on the best strategy for building:

• Should I go with a 1-bedroom, 1-bath ADU, a 2-bedroom, 2-bath ADU, or even a 3-bedroom ADU?

• Which unit size would rent faster and have higher demand in this area?

• Are there specific trends or tenant preferences in El Cajon that I should consider?

I’d love to hear from anyone familiar with the rental market in El Cajon or who has built/rented ADUs in similar areas. Thanks for your insights!
