How to start a remodeling or general contracting business

To start a remodeling or general contracting business, you need the contractor license or home improvement registration your state and city require, insurance, a written contract for every job, reliable subcontractors with current insurance and licenses, an estimating method that captures every cost, and a payment schedule that keeps cash ahead of expenses. What separates successful remodelers is less about carpentry and more about managing money, schedules, changes and client expectations across jobs that run for weeks.

Many remodelers start as carpenters, tile setters or tradespeople who kept getting asked to "just handle the whole thing." Running whole projects is a different job. This guide covers the business side.

What license do remodelers and general contractors need?

Licensing for remodeling and general contracting varies more than almost any other trade. Depending on where you work, you might need:

• A state general contractor or residential contractor license, often with experience requirements and exams
• A state home improvement contractor registration, sometimes separate from a contractor license
• A city or county license or registration
• A bond, sometimes required as part of licensing
• Proof of insurance on file with the licensing agency

Some states license based on the dollar value of a job or the type of work. Trade work like electrical, plumbing and HVAC typically requires separately licensed contractors even when you are the general contractor.

Contact your state contractor licensing board and your local building department before taking on whole projects. Our contractor licensing and insurance starting point has a list of questions to bring.

What about lead-safe work in older homes?

If you'll renovate, repair or paint in homes built before 1978, federal EPA rules on lead-safe work practices apply to many jobs that disturb painted surfaces, and some states run their own programs. These rules generally involve firm certification, a certified renovator and specific work practices and records. Read the EPA's Renovation, Repair and Painting (RRP) program guidance and check whether your state administers its own program before working on older homes.

What should go in your remodeling contract?

A written contract protects both you and the homeowner. Many states have specific requirements for home improvement contracts, such as required terms, deposit limits and notices about the homeowner's right to cancel. Have an attorney who knows your state write or review your template.

Typical sections include:

• Scope of work, specific enough that two people would read it the same way
• Exclusions, so nothing is assumed
• Price and payment schedule
• Allowances for items the client hasn't chosen yet, like tile or fixtures
• Change order process, including that changes must be in writing and signed before work proceeds
• Schedule and what can affect it
• Permits and inspections, including who obtains them
• Warranty terms
• Required notices, such as cancellation rights or lien law notices required in your state

How do you estimate a remodeling project?

Underestimating is the most common way remodelers lose money. Build every estimate the same way:

1. Walk the job and measure carefully. Photograph everything, including what's behind access panels.
2. Break the project into phases, such as demolition, framing, rough plumbing and electrical, insulation, drywall, finishes and cleanup.
3. Price labor for each phase, using your own crew's real productivity, not hopeful numbers.
4. Get sub bids for trade work, in writing.
5. List materials with current prices, plus waste.
6. Add job costs like permits, dumpsters, portable toilets, equipment rental and protection for floors.
7. Add overhead for your office, vehicles, insurance and your own management time.
8. Add profit as a separate line in your thinking, not as a hope that leftovers will appear.
9. Add a contingency for older homes where surprises are likely, and explain how it works.

Track actual costs on every job against your estimate. That feedback is how your next estimate gets better.

How should payments be scheduled?

On a multi-week job, you buy materials and pay subs and crews long before the job ends. A payment schedule tied to progress keeps you from financing the client's project.

Milestone	What triggers it
Deposit	Signed contract, before ordering materials (check any deposit limits in your state)
Progress payment 1	A defined milestone, such as demolition and rough-ins complete
Progress payment 2	Another defined milestone, such as drywall complete
Final payment	Substantial completion and walk-through

Tie each payment to something visible, not just a date. Invoice promptly when each milestone is reached.

How do you handle change orders?

Changes are inevitable in remodeling. Unsigned changes are a leading cause of disputes and unpaid work.

• Put every change in writing with the price and any effect on the schedule.
• Get it signed before doing the work.
• Add it to the next invoice so the client sees it right away.
• Keep a running total so the client always knows where the project stands.

Customers rarely object to a change they approved in writing. They often object to a surprise on the final bill.

How do you manage subcontractors?

Most remodelers rely on subs for at least some trades. Good subs are a competitive advantage.

• Collect current proof of insurance and license before a sub starts, and track expiration dates.
• Get bids in writing with a clear scope.
• Schedule them clearly and confirm a day or two before.
• Collect lien waivers with payments where your state's lien laws make them relevant. Ask your attorney how lien rights work in your state.
• Pay them on time. The best subs work for the contractors who pay reliably.

Whether a worker is a subcontractor or an employee depends on legal tests, not labels. Ask your accountant.

How do you keep clients happy through a long project?

Remodeling clients are living in a construction zone. Communication matters as much as craftsmanship.

• Set expectations at the start: working hours, noise, dust, bathroom access, who to call.
• Give regular updates, such as a short daily or weekly note with photos.
• Share a schedule that shows what's next.
• Make selections easy with deadlines, so you don't wait on decisions.
• Walk through the project at key milestones.

What about cash flow and bookkeeping?

Remodeling businesses can look profitable on paper and still run out of cash. Keep business and personal money separate, track costs by job, and plan for the gap between paying for materials and getting paid. Our bookkeeping basics for contractors covers the essentials.

FAQ

Do I need a general contractor license to remodel? It depends on your state, city and sometimes the size or type of job. Some states require a home improvement registration, some a contractor license, and some both. Check with your licensing board.

How much deposit can a remodeler take? Some states limit deposits on home improvement contracts. Check your state's rules and have an attorney review your contract.

How do I avoid disputes over changes? Get every change in writing, with price and schedule effects, signed before the work is done.

Should I hire employees or use subcontractors? Many remodelers use both. Classification depends on legal tests, so talk to your accountant.
