How to Size For Title 24 For Apartment Buildings

This will let you know how many bathrooms or laundry rooms you’re going to have to plumbed.

Title 24 green building code for the City of Los Angeles is a game changer for the environment. Here is the information you need to meet the greywater diversion for landscapes. For apartments we suggest plumbing only the number showers or laundry rooms needed to irrigate the landscape during the hottest time of the year : July”.

You first have to calculate how much water you’re going to need to water your landscape.
What you need to do is take the total square footage of your landscape and times it by the Evapotranspiration (ETo) rate for July (link to our website with the numbers for each city),
Then times this sum by .62 to get the total gallons required for the month of July.
Divide this by 31 (number of days in July) this will give you the daily gallon requirements.

1000 Sq Ft x 6 ETo = 6000
6000 x .62 = 3,720 Gallons per month
3,720 / 31 = 120 per day

Now to determine how many bathrooms and or laundry rooms you’ll need to plumb:
25 gallons per tenant per day.
If you have 4 tenants in each apartment, then your water volume per apartment is 100 gallons a day.
Laundry Room:
15 gallons per tenant per day .
