Hiring the wrong contractor is one of the most expensive mistakes a homeowner can make. In Los Angeles County — where the construction market is busy, competition is fierce, and unlicensed contractors are everywhere — knowing the right questions to ask can save you thousands of dollars and months of headaches.
Whether you’re planning a kitchen remodel, a bathroom renovation, a home addition, or any construction project in the San Fernando Valley, use this checklist before signing anything.
1. Are You Licensed by the California Contractors State License Board (CSLB)?
This is the most important question — and the answer must be yes.
In California, any contractor doing work valued over $500 (labor and materials combined) must be licensed by the CSLB. Working with an unlicensed contractor is illegal, and if something goes wrong — an injury on your property, structural damage, shoddy work — you have virtually no legal protection.
How to verify: Go to cslb.ca.gov and search the contractor’s name or license number. You can see their license status, classification, and any disciplinary actions in seconds.

2. Are You Bonded and Insured?
A licensed contractor should also carry:
- General liability insurance — protects your property if the contractor causes damage during the job
- Workers’ compensation insurance — protects you if a worker is injured on your property
If a contractor isn’t insured and a worker gets hurt on your job, you could be held liable. Always ask for a certificate of insurance and verify it’s current.
3. Have You Done Similar Projects in the Los Angeles Area?
Experience matters — especially local experience. A contractor who has worked extensively in LA County understands:
- Local building codes and permit requirements
- City of Los Angeles inspection processes
- Soil and seismic conditions specific to the San Fernando Valley
- Local material suppliers and subcontractors
Ask to see photos of similar completed projects, and if possible, visit a completed job site or speak with a past client.
4. Will You Pull the Permits?
Any reputable contractor will pull the required permits for your project. Permits exist to protect you — they ensure the work is inspected by the city and meets California building codes.
Red flag: A contractor who suggests skipping permits to “save money” is putting you at serious risk. Unpermitted work can:
- Void your homeowner’s insurance
- Create problems when you sell your home
- Result in fines and mandatory removal of the work
- Leave you with no legal recourse if the work is defective
Always insist on proper permits. GN Builders handles all permit applications and city inspections as part of every project.
5. Who Will Actually Do the Work?
Many general contractors subcontract work to other crews. This isn’t necessarily a problem — it’s standard practice — but you should know:
- Who are the subcontractors?
- Are they licensed and insured?
- Will the general contractor supervise the work daily?
A good general contractor takes full responsibility for everyone on your job site, regardless of whether they’re direct employees or subcontractors.
6. Can You Provide a Detailed Written Estimate?
Never accept a verbal quote or a vague one-page proposal. A professional contractor should provide a written estimate that includes:
- Itemized scope of work
- Materials to be used (brand, model, specifications)
- Labor costs
- Payment schedule
- Project timeline
- What is and isn’t included
Vague estimates lead to disputes and unexpected charges. A detailed written proposal protects both parties.
7. What Is the Payment Schedule?
Be very cautious about contractors who ask for large upfront payments. In California, a contractor cannot legally require a deposit of more than 10% of the total contract price or $1,000 — whichever is less — before work begins.
A typical payment schedule for a legitimate contractor looks like:
- 10% deposit at signing
- Progress payments tied to completion milestones
- Final payment upon job completion and your approval
Red flag: Any contractor asking for 50% or more upfront is a warning sign. This is one of the most common patterns in contractor scams in Los Angeles.
8. What Is the Estimated Timeline?
Get a clear start date and estimated completion date in writing. Ask:
- When can you start?
- How many days per week will your crew be on site?
- What could delay the project, and how will you handle it?
- Will you be working on other projects at the same time?
A contractor juggling too many projects at once is a common reason jobs drag on for months beyond the original estimate.
9. How Will You Protect My Home During Construction?
Construction is messy. A professional contractor should have a clear plan for:
- Protecting floors, furniture, and finishes from dust and damage
- Securing the job site at the end of each day
- Disposing of debris and waste properly
- Minimizing disruption to the parts of your home you’re still using
Ask how they handle cleanup — daily, or only at the end of the project.
10. Do You Offer a Warranty on Your Work?
Reputable contractors stand behind their work. Ask:
- What warranty do you offer on labor?
- How do you handle issues that come up after the job is done?
- Are there manufacturer warranties on materials?
In California, there is an implied warranty of good workmanship on all construction projects, but having a contractor who explicitly commits to fixing problems after completion gives you additional peace of mind.
Bonus: Trust Your Gut
Beyond these ten questions, pay attention to how a contractor communicates. Do they return calls promptly? Do they show up on time for the estimate? Do they listen to what you want, or try to push their own preferences?
The way a contractor behaves before you hire them is a preview of how they’ll behave during the job.

If something feels off — trust your instincts and keep looking.
