About the ACSP & Designer Certifications

The ACSP is a professional trade association for the closet and home-storage industry. Its members and certified designers commit to a shared standard of professionalism, training, and accountability.

Why it matters to homeowners

Whether a company belongs to the ACSP, the CIA, or another recognized trade association, that affiliation is a helpful signal. Working with a trade-association member means you benefit from:

  • Professionals who invest in training and stay current with industry practices.
  • A recognized certification path that verifies design skill and experience.
  • Accountability to shared standards of professionalism and conduct.
  • Added confidence that your project is in capable, qualified hands.

What is the ACSP?

The Association of Closet and Storage Professionals (ACSP) is a trade association serving companies and professionals in the custom closet, garage, pantry, and home-storage industry. It provides education, professional designer certifications, and a shared framework of best practices that help members deliver consistent, high-quality results to homeowners.

Like other respected trade associations, the ACSP gives independent local companies a way to demonstrate their commitment to the craft and to ongoing professional development.

What ACSP membership means

An ACSP affiliation signals that a company participates in an organized professional community. In practice that means:

  • Access to industry training, resources, and continuing education.
  • A commitment to professional standards of design and installation.
  • A pathway to recognized designer certifications that verify skill and experience.
  • Membership in a broader community focused on advancing the storage-design profession.

ACSP designer certification levels

The ACSP offers tiered professional designations. On a company's profile you may see one of these designer levels, which reflect the professional's training and experience:

RSDRegistered Storage Designer

Entry professional designation for storage design professionals.

CSDCertified Storage Designer

Certified professional with demonstrated storage-design competency.

MSDMaster Storage Designer

Highest ACSP designer designation, reserved for master-level professionals.

RIRegistered Installer

Professional trained and registered in proper storage-system installation.

The ACSP education day

Beyond certification, the ACSP leads a dedicated day of education at the annual Closets Conference & Expo — the industry's only national closets event. It is where designers and installers stay current with new techniques, materials, and best practices.

Learn what happens at the conference and why continuing education matters when you hire a professional — see our ACSP Conference guide.

Custom Closet Finder is association-neutral. We list independent local companies regardless of affiliation and simply highlight recognized memberships — such as the ACSP and the CIA — so you can factor them into your decision.
