Hiring a general contractor in New York City is one of the biggest decisions you’ll make during a renovation. The right contractor makes the process smooth, transparent, and stress-free. The wrong one can cost you months of delays, thousands in unexpected charges, and a finished product that doesn’t match what you were promised.
Here’s how to evaluate contractors and make the right choice — based on what actually matters in the NYC market.
1. Verify Their License and Insurance
This is non-negotiable. In New York City, general contractors must carry:
- NYC Home Improvement Contractor License — issued by the Department of Consumer and Worker Protection (DCWP). You can verify any contractor’s license at nyc.gov/consumers.
- General liability insurance — minimum $1M per occurrence (many co-op and condo boards require $2M)
- Workers’ compensation insurance — covers any worker injured on your property
If a contractor can’t produce current certificates for all three, walk away. Working with an unlicensed or uninsured contractor puts you at legal and financial risk — and most co-op and condo boards won’t approve the work at all.
2. Ask About Their Experience With Your Type of Project
NYC renovation is specialized. A contractor who’s great at brownstone gut renovations may not have experience with co-op alteration agreements. Someone who specializes in commercial fit-outs may not understand residential finishing standards.
Ask specifically:
- Have you done this type of project before? (kitchen, bathroom, gut renovation, etc.)
- Have you worked in my building type? (co-op, condo, townhouse, pre-war, new construction)
- Can you show me photos of similar completed projects?
- Can I speak with a recent client who had a similar scope?
3. Get a Detailed Written Estimate
A professional contractor should provide a written estimate with line-item breakdowns — not a single lump sum on a napkin. Your estimate should include:
- Scope of work (exactly what’s included and what’s not)
- Material specifications (brand, model, grade — not just “tile” or “countertop”)
- Labor costs broken out by trade
- Permit costs and filing fees
- Projected timeline with milestone dates
- Payment schedule tied to milestones (never pay 100% upfront)
Red flag: If a contractor won’t put it in writing, or if the estimate is vague (“approximately $50K”), keep looking. In NYC, where project costs are significant, you need precision.
4. Understand Their Team Structure
Some contractors are true general contractors who manage their own crew. Others are essentially brokers who subcontract every trade to different companies. Neither is inherently bad, but you should know what you’re getting:
- In-house crew: One team, one point of contact, consistent quality. The contractor has direct control over everyone on your job site.
- Subcontracted: The GC coordinates multiple specialty companies. This can work well if the GC is experienced at project management, but it adds communication layers and can lead to scheduling conflicts.
At MH Construction, we use our own in-house crew for the vast majority of work. You’ll know everyone on your job site by name.
5. Check Their DOB Track Record
The NYC Department of Buildings maintains public records of all permit filings, violations, and complaints. You can search any contractor’s history at the DOB BIS website. Look for:
- A history of successfully closed-out permits (work completed and inspected)
- No open violations or stop-work orders
- No pattern of complaints from building owners
6. Pay Attention to Communication
How a contractor communicates before the project starts is a strong indicator of how they’ll communicate during it. Notice:
- Do they respond to calls and emails within 24 hours?
- Do they show up on time for the initial site visit?
- Do they explain things clearly without jargon?
- Do they listen to your priorities, or do they push their preferences?
Renovation projects run for weeks or months. You need a contractor you can communicate with easily — especially when decisions need to be made quickly.
7. Never Pay Everything Upfront
A standard payment schedule for NYC renovations looks like this:
- 10–15% deposit to secure the start date and order materials
- Milestone payments (e.g., 25% at demolition complete, 25% at rough-in complete, 25% at finishes)
- Final 10–15% after walkthrough and punch-list completion
If a contractor asks for 50%+ upfront, that’s a red flag. Tying payments to milestones protects both parties and ensures the work progresses before money changes hands.
Questions to Ask During the First Meeting
Come prepared with specific questions: What is your timeline for a project like mine? Who will be on site daily? How do you handle change orders? What happens if the project runs over schedule? A professional contractor welcomes these questions — they show you are serious and organized, which leads to a better working relationship.
