Why Rebates Matter for Multifamily Toilet Replacement

Water conservation rebate and incentive programs can offset 20-40% of your total project cost, dramatically improving your already-strong ROI. The challenge is that these programs exist at federal, state, and local levels, each with different eligibility requirements, application processes, and deadlines.

At Multifamily Toilet Replacements, we've secured over $1 million in rebates for our clients. Here's your comprehensive guide to every major program available in 2026.

Federal Programs

Fannie Mae Green Rewards

Fannie Mae's Green Rewards program offers reduced interest rates (typically 10-15 basis points) on multifamily loans for properties that implement water and energy efficiency improvements. Toilet replacement qualifies as a water efficiency improvement, and the reduced interest rate can save tens of thousands of dollars over the life of the loan.

Freddie Mac Green Advantage

Similar to Fannie Mae's program, Freddie Mac offers favorable loan terms for properties with green certifications or that implement efficiency improvements. Water fixture replacement is a qualifying improvement that can help your property access these preferential terms.

EPA WaterSense Program

While not a direct rebate program, EPA WaterSense certification for your fixtures ensures eligibility for most state and local rebate programs. All Niagara Stealth toilets carry the WaterSense label, meaning your replacement project automatically qualifies.

State-Level Programs

Many states offer direct rebates for water-efficient fixture installation. Here are some of the most significant:

  • California: Multiple water district programs offering $75-$150 per toilet replaced
  • Texas: San Antonio Water System offers up to $100 per toilet for commercial properties
  • Arizona: Phoenix and Tucson water districts offer $75-$100 per toilet
  • Florida: Several water management districts offer per-fixture rebates
  • Georgia: Atlanta-area utilities offer commercial water efficiency rebates
  • New York: NYC DEP offers rebates for water-efficient fixtures in multifamily buildings
