Koreatown Owners Pay $0 for New Toilets
LADWP pays up to $300 for each toilet replaced in a building with 5 or more units, and that covers the whole job. With one toilet per unit, a typical 15-unit Koreatown building gets up to $4,500 of new fixtures and labor, paid by LADWP instead of you.

Koreatown Has More Apartment Units Than Any LA Neighborhood
Koreatown has 38,026 apartment units in 1,563 buildings with 5 or more units built before 2014. That is more units than any other neighborhood in the City of Los Angeles. Half of those buildings went up in 1956 or earlier, and 98.7% were built before 1994, the year 1.6 gallons per flush became the federal standard for new toilets.
Koreatown’s buildings are also large. 653 of them have 20 or more units, and those buildings hold about three of every four apartments here. With crews installing up to 50 toilets a day, most of them are finished in one or two days.
If your building is one of them, LADWP will pay to replace its old toilets, and we will handle the work from the first form to the final inspection.

Does Your Koreatown Building Qualify?
- Your building has 5 or more residential units
- The water account is with LADWP
- The toilets are rated 1.6 gallons per flush (GPF) or higher
- You own or manage the building (the water account holder signs)
- If your building meets all four criteria, the replacement costs you nothing.
Koreatown is part of the City of Los Angeles, and LADWP lists it among the communities it serves with water, so the territory test is already met. That leaves one test: the toilets. If your building went up before 2014 and has not had a full retrofit, it most likely still has toilets rated 1.6 GPF or higher.

A Typical Koreatown Building Saves $3,800 a Year
The typical Koreatown apartment building has 15 units. At July 2026 rates it pays about $11,000 a year in sewer charges alone, and about $13,000 from July 2028. New toilets cut the water charge and the sewer charge at the same time.
| Building size | Sewer charge a year, July 2026 | Sewer charge a year, July 2028 | Saved a year with new toilets |
|---|---|---|---|
| 15 units (typical here) | $11,000 | $13,000 | $3,800 |
| 20 units | $14,700 | $17,400 | $5,100 |
| 50 units | $36,700 | $43,400 | $12,700 |
| 100 units | $73,500 | $86,800 | $25,400 |

Estimates use the same assumptions as our sewer rate guide: 6.5 HCF of water per unit a month, sewer billed on 93% of it, and new toilets saving about 12.5 HCF per unit a year at July 2026 water and sewer rates. Your building’s own bills decide the real number.
The new toilets, installation and haul-away cost you nothing, so the yearly savings start with your first bill after the work.
How the Toilet Rebate Program Works
From the first call to new toilets in every unit usually takes 4 to 5 weeks. You sign one authorization form. We handle the rest.
1
Building check
Send us your building details. We confirm the unit count, the LADWP water account and the toilet ratings, with no commitment.
2
Pre-inspection
An inspector checks the GPF stamp on a sample of toilets, counts the eligible ones and notes any plumbing issues. It takes 1 to 2 hours.
3
LADWP approval
We file the application through SoCal Water$mart. Approval takes about 10 business days.
4
Installation
We give tenants notice, then replace each toilet in about 20 minutes, up to 50 a day, and haul the old ones away.
5
Inspection and rebate
The program inspects the work and pays the rebate to the water account holder. We invoice only that amount, after it arrives.

Frequently Asked Questions
It qualifies if it has 5 or more units, an LADWP water account and toilets rated 1.6 GPF or higher. Koreatown is in the City of Los Angeles, so LADWP supplies its water. Of the 1,563 apartment buildings with 5 or more units built in Koreatown before 2014, 98.7% went up before 1994, so many still have the toilets the program replaces.
Yes. LADWP pays up to $300 per toilet, which covers the new fixture, installation and haul-away. The program pays that rebate to the water account holder, and Planet Optima invoices only that amount after it arrives, so the owner pays nothing up front and comes out even.
A typical 15-unit Koreatown building saves about $3,800 a year on water and sewer at July 2026 rates. A 100-unit building saves about $25,400 a year. Sewer rates rise again in July 2027 and July 2028, so the savings grow too.
About 4 to 5 weeks from the first call to finished work, and LADWP approval takes about 10 business days of that. The installation itself is fast: about 20 minutes per toilet and up to 50 toilets a day, so a typical 15-unit Koreatown building is done in one day.
We replace only the toilets still rated 1.6 GPF or higher, and the pre-inspection counts them. Buildings that joined an earlier MWD or LADWP program can often take part again for the units that still have older toilets.
Very little. We give tenants notice first, each toilet takes about 20 minutes, and crews work unit by unit, so every bathroom is back in use the same day.
WaterSense-certified, MaP-tested high-efficiency toilets rated at 0.9 GPF or lower. They flush as well as or better than the 1.6 GPF models they replace, and they are made to work with older multifamily plumbing, including cast-iron drain lines.
No. The water account holder, usually the owner or the property manager, signs the authorization form. Tenants can pass this page to their landlord or manager, and we will take it from there.
Yes. We replace toilets in apartment buildings with 5 or more units anywhere LADWP supplies the water, including Westlake, Hollywood, Mid-Wilshire, East Hollywood and Pico-Union.
