NJ Form OS/SS-32 Homemade Trailer Title Guide – If you built a trailer yourself in New Jersey and it weighs more than 2,500 pounds unladen, you must obtain a Certificate of Title before you can legally register and operate it on public roads. The official form for this process is Form OS/SS-32, titled “Application for Certificate of Title – Homemade Trailer,” issued by the New Jersey Motor Vehicle Commission (MVC).
This guide explains when the form is required, what supporting documents you need, how to complete the application, current fees, safety rules, and where to submit everything. All information is based on official New Jersey Motor Vehicle Commission sources.
What Is New Jersey Form OS/SS-32?
Form OS/SS-32 is the specialized application used solely for homemade (owner-built) trailers that exceed 2,500 pounds unladen weight. Because these trailers lack a manufacturer-assigned Vehicle Identification Number (VIN), the MVC reviews the application and assigns a serial/VIN number as part of the titling process.
The current version of the form is OS/SS-32 (R7/25). It collects details about the trailer’s construction date, dimensions, type (four-wheel trailer or semi-trailer), owner information, and a certification that the trailer is roadworthy and meets New Jersey inspection standards.

When Is a Title Required for a Homemade Trailer in New Jersey?
Under New Jersey law, trailers (manufactured or homemade) and semi-trailers weighing less than 2,500 pounds unladen must be registered but are exempt from titling. Any trailer weighing more than 2,500 pounds unladen must be both titled and registered.
This 2,500-pound threshold is the key factor that determines whether Form OS/SS-32 is needed. If your homemade trailer falls under the limit, you still need to register it using Form BA-49, but you do not apply for a title.
Official guidance is available on the MVC trailer information page: NJ MVC Trailers, House Semi-trailers and Private Utilities.
Required Documents to Title and Register a Homemade Trailer
According to the New Jersey Motor Vehicle Commission, applicants must bring or submit the following items:
- Proof of identification (driver license or other accepted primary ID that meets the 6-point verification requirements)
- Original receipts or titles for all major parts used in construction
- A notarized statement that includes detailed construction information
- A certified weight slip from a public scale showing the unladen weight
- Color photographs of the trailer from all angles
- Completed Vehicle Registration Application (Form BA-49)
- Completed Application for Certificate of Title for Home-Made Trailer (Form OS/SS-32)
- Completed Universal Title Application (Form OS/SS-UTA)
- Payment for the applicable registration fee (Code 22) and title fee (if the trailer weighs more than 2,500 lbs unladen)
The Universal Title Application is available here: Form OS/SS-UTA (PDF).
The Vehicle Registration Application is available here: Form BA-49 (PDF).
How to Complete Form OS/SS-32?
The form is relatively short but requires accurate information. Key sections include:
- Trailer Type — Check either “Four Wheel Trailer” or “Semi Trailer.”
- Date Constructed — Enter the month, day, and year the trailer was completed.
- Dimensions — Provide length, width, and height in feet and inches.
- Serial/Vehicle Identification Number — Leave blank; the MVC will assign this number.
- Owner and Co-Owner Information — Full legal name, street address, city, state, ZIP code, and New Jersey driver license number (or corporate code if a business).
- Certification — The owner must sign and date the statement confirming the trailer is roadworthy, that required equipment has been approved, and that construction meets industry standards and New Jersey inspection requirements.
A certified weight slip must be attached. The form also reprints important equipment rules that every applicant should review carefully.
Safety and Equipment Requirements for Homemade Trailers
New Jersey law sets clear standards that appear on Form OS/SS-32 itself:
- Every trailer or semi-trailer must have brakes on all wheels, with limited exceptions for lighter units (gross weight not exceeding 3,000 pounds, provided the trailer’s gross weight does not exceed 40% of the towing vehicle’s gross weight).
- Two tail lamps, two stop lamps, two turn signals, and two rear reflectors are required.
- Adequate license-plate illumination is mandatory.
- The hitch must connect directly to the chassis of the towing vehicle — not to the bumper.
In addition, dimension limits under N.J.S.A. 39:3-8 apply:
- Maximum width: 96 inches
- Maximum height: 13 feet 6 inches
- Maximum length (single vehicle): 35 feet
- Maximum length (semi-trailer + towing vehicle): 48 feet
- Maximum length (trailer + towing vehicle): 58 feet
Safety equipment such as mirrors or lights is excluded from these measurements if it does not cause the overall dimensions to be exceeded.
Fees for Titling and Registering a Homemade Trailer
Current New Jersey MVC fees (subject to change) are:
- Title fee: $60 for a standard title (no lien). Additional fees apply if a lien is present ($85 with one lien, $110 with two liens).
- Registration fee (Code 22 – Private Utility or House-Type Semi-trailer): $18 if 2,000 lbs or less; $23 if over 2,000 lbs. All trailer registrations expire on March 31 regardless of the month of issuance.
Sales tax at the New Jersey rate of 6.625% may also apply depending on the circumstances of acquisition or construction. Confirm current amounts and payment methods (check, money order, or in-person credit/debit) with the MVC before submitting.
