Get Started - Volume Program

Ready to get started? Enroll in the IREM CSP Volume Program on the application platform.

You’ll be required to provide documentation on your company’s portfolio-level policies and programs that align with items on the CSP checklist for your property type. IREM will then evaluate these policies and programs, and potentially credit those CSP items covered at the portfolio level—streamlining the checklist and application process.

After enrolling, companies are eligible for the Volume Program for three years, after which they may re-enroll. Volume Program participants may certify as many properties as desired in each year of eligibility, with a total of at least 10 properties certified by the end of eligibility.

Application fee discounts are available at the following levels:
