Do You Need a License for Siding Repair? (By State)

It depends on your state, and sometimes your city. Some states make anyone doing residential siding repair register or get a license: Massachusetts, New Jersey, Pennsylvania, Maryland and Michigan, for example. Others, like California and Virginia, only require a license once a job passes a set dollar amount. Texas and Illinois have no state license for siding at all, but cities in both states have their own rules. Look up your state and your city before you hand out your first card.

Below are real examples of how the rules differ, with the dollar amounts that trigger them, and then a quick way to check your own area.

Why the dollar amount matters more than you think

Our average repair ticket runs about $350. Plenty of states let small jobs slide under a dollar limit, so a guy figures he's covered. Two problems with that.

First, the limit usually covers labor and materials together, and sometimes it counts what you do in a whole year. Second, the jobs that pay best are the ones that go over it: a full wall after a windstorm, or a run of panels plus J-channel and soffit. If you only plan for the $350 job, the $2,400 job is the one that puts you out of bounds.

States that register or license home improvement contractors

These states want you on their list before you do residential repair work, siding included. Fees are as of October 2026.

Massachusetts. If you bid on or do residential work on an existing owner-occupied home with one to four units, you register as a Home Improvement Contractor (HIC) under Chapter 142A. Siding is one of the covered trades. The fee is $150, plus a one-time payment into the state Guaranty Fund: $100 if you have zero to three employees, and more as you add people. The fund pays homeowners up to $25,000 on unpaid judgments against registered contractors.

New Jersey. Home improvement contractors register with the Division of Consumer Affairs. The fee is $110 for the first registration and $110 at each renewal. You also have to carry commercial general liability insurance of at least $500,000 per occurrence for home improvement work.

Pennsylvania. You register with the Attorney General's office if you do $5,000 or more in home improvements a year. Registration costs $100 every two years. You need at least $50,000 in bodily injury coverage and $50,000 in property damage coverage. Do the math: at $350 a ticket, you pass $5,000 by your 15th job, likely in your first month or two. If you're going to work in Pennsylvania, plan to register.

Maryland. Siding falls under the Maryland Home Improvement Commission (MHIC) license, the same one that covers remodeling, roofing and decks. New contractors pay a $100 Guaranty Fund assessment on top of the application fee, and $175 every two years when they renew. Go by the MHIC fee page for the current application cost.

Michigan. Michigan has one of the lowest triggers in the country. Residential work of $600 or more, counting labor and materials, needs a license from LARA. A one-man siding outfit usually goes for the Maintenance & Alteration (M&A) contractor license, which covers trades like siding on existing homes. You need a 60-hour pre-license course before you sit for the state exam. You can't break a $1,200 job into two $600 invoices to stay under.

If you're switching over from another trade and already hold a contractor license, check whether it covers siding before you buy a second one. See From Framer, Roofer or Handyman to Siding Repair.

States with a dollar threshold

California. As of January 1, 2025, Assembly Bill 2622 lets you do a job without a CSLB license if all three of these are true:

1. The whole project, labor and materials and everything else, comes to $1,000 or less.
2. The job needs no building permit.
3. You don't employ anyone on it.

That was raised from $500, the first increase since 1987. The CSLB counts the project, not the invoice, so two $900 bills for one $1,800 job aren't exempt. You can advertise unlicensed only for work under $1,000. Most single-panel repairs fit. A storm-damaged elevation usually won't.

Virginia. The Department of Professional and Occupational Regulation (DPOR) requires a contractor license on jobs over $1,000 for construction, repair or improvement. The entry level is the Class C license, which takes a year of experience and a pre-license course. DPOR has changed the Class C limits recently, so check the current ones on its site before you apply.

Minnesota works a little differently. You need a residential building contractor or remodeler license if you do two or more special skills on one- to four-family homes. Contractors who offer only one special skill don't need the license, except roofers. Separately, if you take in less than $15,000 a year from residential work, you can apply for a Certificate of Exemption. If you sell siding plus other exterior work, ask the Department of Labor and Industry whether that counts as one skill or two before you print the truck lettering.

States with no state license, but local rules

Texas has no state general contractor license, and siding isn't one of the trades the state licenses. But Austin, Dallas, San Antonio, Fort Worth and other cities have their own contractor registration and insurance rules before you can pull a permit.

Illinois has no state license or statewide registration for home improvement contractors. Roofers are licensed by the state, plumbers too. Cities and counties often have their own: Chicago requires a General Contractor license for most building alteration and repair work inside city limits.

The point for both: "no state license" doesn't mean "no license." The city building department is where you'll find out.

Unlicensed work can cost you more than a fine

If you work without the registration your state requires, the fine is only part of it. In some states, being unregistered can make it harder to enforce your contract when a customer doesn't pay, which is the last spot you want to be in. Ask your state's licensing office what happens to your right to collect if you're unregistered, and keep What to Do When a Customer Won't Pay handy either way.

How to check your own state in about an hour

1. Search "[your state] home improvement contractor registration." Use the result on the .gov site, usually the attorney general, consumer affairs or a contractor board. Skip the paid "license services" sites.
2. Find the dollar trigger. Is it per job or per year? Does it count materials? Does a permit change things?
3. Check the insurance minimum. Several states set one. You'll want general liability anyway.
4. Call your city and county building departments. Ask: "I do residential siding repair. Do I need a local license or registration, and when do I need a permit?"
5. Check every town you'll work in. If you live near a state line, check both states. Pennsylvania, New Jersey and Maryland all sit close together, and their rules aren't the same.
6. Write it down. Registration number, renewal date, insurance minimum. Put the renewal date on your calendar.

Rules change. California raised its limit in 2025 and Virginia changed its Class C limits too, so check again every year when you renew your insurance.
