“A paperhanging contractor applies all types and varieties of decorative wall coverings, except painting or paneling, including paper and vinyl goods, cork, burlap, and carpet-type wall coverings” – CSLB.GOV

The C-61/D-29 License is the classification required in the state of California for anyone looking to contract for projects involving the application of decorative wall coverings where the cost of labor and materials exceeds $500.

Duties associated with the Paperhanging License

In many ways, the paper hanging license is essentially a classification for interior designers looking to grow their businesses legally in California.

Some paper-hanging contractors may also hold the C-33 Painting Contractor license.

Paperhanging contractors may offer a few different services including:

  • Safe and environmentally friendly wall paper and material removal
  • Material selection and acquisition 
  • Surface preparation
  • Paper hanging and Wall Paper removal
  • Wall Covering Installation
  • Ergonomic Evaluations
  • Custom Interior Services and Office Design
  • Wall paper design and installation
  • Picture frame design, installation and repair
  • Using ladders, scaffolds, and planks
  • Adhering to EPA and OSHA guidelines
  • Site evaluations
  • Bidding, estimating , and accounting

Paperhanging contractors generally work closely with the client to bring to life their specific ideas on how they want the interior of their home or building to look.

Paperhanging contractors employ a wealth of knowledge on colors, spacing, material and stylistic sensibility to create timeless decorative interiors.


Contractors that specialize in window coverings are typically hired to work in a residential setting directly with homeowners or small businesses.

However, they may also function as a subcontractor. In a construction setting,  a General Contractor may place a bid that includes customized interior decorating.

They would oversee that the paper-hanging phase of the project is completed correctly.

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-29 Paperhanging contractor license is issued to contractors by the CSLB. 

How to get a Paperhanging Contractor License

To get the C-61/D-29 license you must prove a minimum of 4 years journeyman level experience and pass a law exam.

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 #
  • check 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 journey level experience?

Journeyman-level experience means that you have worked unsupervised full time for an interior decorator or for a contractor that holds the C-61/D-29 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 act as a Qualifying Individual when applying for the paperhanging contractor license:

  • Licensed General Contractor
  • C-61 / D-24 License Holder
  • Former Supervisor (within the last 10 years)
  • check Fellow Employee (within the last 10 years)
  • check Business Associate
  • check Fellow Journeyman
  • check Union Representative

How to fill out the Contractor License application

In addition, your Qualifying Individual will need to provide a brief but detailed description of your knowledge and skillset.

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

For example: 

“Sarah has a lot of experience applying decorative wall covering” is not descriptive enough.

 The CSLB will want to see something more like:

“Sarah has designed and installed interior wallpaper, artwork, lighting, and furniture. She has picked up colors worked with painting contractors” etc.

Most importantly, the description written by your qualifying individual has to include the core skills required for the contractor's license.

Work experience for the Contractor License

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

Can you get a Contractors License with a Felony in California?

Having a criminal record in no way stops you from getting a C-61/D-29 Paperhanging 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.

When making alterations to or around structures built before 1978, window contractors must know how to contain lead paint if it is present. Rules for Lead paint are set by the Environmental Protection Agency.

Lead paint can travel miles through air, rest on soil, and enter air ducts causing potentially fatal respiratory damage.
