“A suspended ceiling contractor installs, modifies or repairs all types of suspended ceilings, including but not limited to the following: lay-in-grid and other types of systems involving solid, perforated or translucent ceiling panels (no electrical work)” – CSLB.GOV

  • The C-61/D-50 is the classification required in the state of California for all persons looking to bid on suspended ceiling projects where the cost of labor and materials exceeds $500

Typical duties of a Suspended Ceiling Contractor

A Suspended Ceiling is a type of secondary ceiling commonly found in residential and commercial architecture.

Suspended Ceiling services may encompass a few different activities including:

  • Suspended ceiling installation and repair

Installation, repair, and maintenance of suspended ceilings

A suspended ceiling may be used for a variety of reasons most often for: 

  • Increased ventilation
  • Improved Sustainability  
  • To house concealed grid systems 
  • Improved acoustics

This trade can be highly lucrative to any contractor that has the proper license and bonding.

What is a subcontractor?

Contractors that specialize in suspended ceilings are typically hired to work in a commercial setting. Property owners of office buildings and small businesses typically utilize suspended ceilings.

However, they may also function as a subcontractor to General Construction Company.

The General Contractor would oversee that the suspended ceilings phase of the project has been executed safely.

Contractors State License Board

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California. Their sole responsibility is to protect the consumer public. 

They ensure that anyone charging over $500 for construction services is qualified and registered with the state.

The C-61 / D-50 Suspended Ceilings contractor license is issued to contractors by the CSLB. 

C-61/D-50 Suspended Ceiling Contractor License Requirements

To get a suspended ceiling contractor license in California, you must prove a minimum of 4 years of journeyman level experience and pass a two-part state exam with the Contractor State License Board.

To qualify for an exam date you must meet the following requirements:

  • Be at least 18 years of age
  • Have a valid Driver's License or USA Issued Identification
  • Have a Social Security or ITIN #
  • Not Currently be on probation or parole

You must also have:

  • 4 Years Journey Level Experience
  • A Qualifying Individual to sign off on your experience
  • A way to prove your experience if the state asks for documentation

What is a Journey level experience?

Journeyman level experience means that you have worked unsupervised full time for a suspended ceilings company, or for a contractor that holds the D-50 License.

  • A journeyman can perform all of the duties associated with his or her trade.

The CSLB will want to see four full-time years over the last ten years. The years do not need to be consecutive, but they do need to be four years in total. 

Signature of a Qualifying Individual

The following people may be used as Qualifying Individuals to sign off on your experience when applying for the suspended ceiling contractor license:

  • Licensed General Contractor
  • C-61/D-50 License Holder
  • Fellow Employee (within the last 10 years)
  • Former Supervisor (within the last 10 years)
  • Business Associate
  • Fellow Journeyman
  • Union Representative

Filling out the Contractor License Application

Your Qualifying Individual will also need to provide a brief but detailed description of your knowledge and skillset.

The way this description is written will be critical to whether or not your application is accepted.

For example:

“Ted is a nice guy and very experienced” is not descriptive enough.

 The CSLB will want to see:

“Ted has installed custom ceilings, T-bar, and suspended ceilings. He has experience with suspended acoustical tiles, paint tiles and preventative maintenance to existing ceiling systems” etc.

The description written by your qualifying individual will need to include the core skills required for the ceiling contractor license.

Work experience for the Suspended Ceiling Contractor License

The CSLB may request to see documentation of your work experience

You must be prepared to submit documentation supporting the experience you claim to have. The Contractors State License Board gives you a few ways that you can prove your experience which include:

  • Tax Returns
  • Check Stubs
  • Contracts
  • Material Order Invoices or Receipts

The CSLB  receives thousands of applications per month so there is a good chance they won’t document your experience but if you are one of the applicants that get reviewed you will need to be ready to submit something. 

The CSLB does not accept pictures of projects.

Application Processing, Fees and Criminal History

The time it takes to get your application processed and assigned a test date fluctuates throughout the year.

Typically you can expect:

  • 6-8 Week Application Processing Time
  • 3-4 Week wait for an Exam date

I have seen some situations where applicants got their test date sooner and somewhere they got their test date much later.

The most common reasons your application would get held up are:

  1. Time of year (processing time slows down during the holidays) 
  2. Criminal History 
  3. Proving Experience
  4. Mistakes on your application 

Contractor License Fees

The Current CSLB fees are:

You will need to complete fingerprinting when applying for the D-50 license

Having a criminal record in no way stops you from getting a C-61/D-50 Suspended ceilings contractor License. I have personally helped guys with all types of criminal records obtain multiple licenses.

The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.

BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case-by-case basis.

Remember, their responsibility is to protect the public. Typically the CSLB is most concerned with Fraud, Embezzlement, and Forgery.
