A specially constructed or modified vehicle (SPCNS) is a homemade or kit vehicle built for private use, not made by a licensed manufacturer and not eligible for resale. These vehicles may be built from a kit and may include a combination of new and used parts, especially if they are constructed using a junked vehicle that was previously dismantled.
Registering a Specially Constructed Vehicle
To register a specially constructed vehicle (including a kit commercial vehicle), you will need:
- A completed Application for Title or Registration (REG 343) form.
- A vehicle verification by an authorized DMV employee.
- Bring your vehicle to a DMV office for verification.
- A completed Statement of Construction (REG 5036) form.
- Bills of sale and/or receipts for major component parts (the engine, frame, transmission, and body).
- If the vehicle is a trailer constructed from a purchased kit, please present the Manufacturer’s Certificate of Origin or a receipt or invoice identifying the kit purchased.
- Official Brake and Light Adjustment Certificates
or electronic Vehicle Safety Systems Inspection (VSSI) certificates. - A weight certificate from a California Certified Public Weighmaster, if the vehicle is a pickup or truck.
- A smog certification.
- Registration fees.
- Visit a DMV office to begin the application process.
A SPCNS vehicle does not refer to a vehicle that has been repaired or restored using replacement parts, or to a vehicle modified from its original design.
Example: A Volkswagen “Beetle” with modified fenders, engine compartment lid, and front end is not considered a specially constructed vehicle because it is still recognizable as a Volkswagen “Beetle”.
Altered Vehicles
If you change or alter your vehicle’s body and spend more than $2,000 or more on the alterations, or if your alterations place the vehicle in a different weight classification, you must report these alterations to DMV.
