@Justin R. Thanks for the response.
The site is CUPD-CT. Per the municipal code if none of the lot is in the CUPD zone it will be considered as RM-2-5. Since this CT lot doesn't extend to the CUPD zone so I can consider it as a purely multiple family lot.
You made a very good point on the affordable rent. The code said the following:
Made affordable to very low income, low income, or moderate-income households (30% of 50% AMI, 30% of 60 AMI and 30% of 100% AMI for rental units)
The code has made the affordable housing income requirement very clear but it doesn't tell us what is the ratio required for each income group. Can I make all the affordable units only for moderate income household?
Per the county website 2021 AMI:
80% AMI for a household of 4 is US 97000. 30% of that is US 29100 so the monthly rent can be US 2425. That is still considered as a very high rent for a 2 bedroom apartment in City Heights!!!
30% of 50% AMI is US 1515/month of rent. That is still not too bad in City Heights.
It seems that it makes perfect sense to build affordable housing in City Heights.
For these type of land use question, where is the best place to get the correct answer? The city office on 1st ave or do I have to hire land use attorney to interpret the code for me? Seems like a overkill to hire attorney for a small project...
