What Does a General Contractor Really Do?

Written By Nail & Hammer Construction Corp

When you decide to build, remodel, or add an ADU to your property, one of the first questions you’ll face is: Do I need a general contractor?
The short answer — absolutely. But the longer answer is worth exploring, because understanding what a general contractor (GC) really does can save you time, money, and countless headaches during your construction journey.

The General Contractor’s Role Explained

A general contractor is the conductor of the entire construction orchestra. While individual trades like plumbers, electricians, and framers each play a vital role, the GC is responsible for making sure every moving part works together — on time, on budget, and according to code.

At Nail & Hammer Construction Corp, we see our role as more than just managing the build. We’re responsible for the entire lifecycle of a project, from concept to completion.

Here’s what that looks like in practice:

1. Pre-Construction Planning

Before the first nail is hammered, the general contractor lays the groundwork for a successful project. This includes:

  • Site evaluation: Reviewing your lot, soil, and zoning to identify opportunities or potential challenges early.

  • Permitting and compliance: Navigating the complex Los Angeles permitting process through LADBS (Los Angeles Department of Building and Safety).

  • Estimating and budgeting: Preparing detailed cost breakdowns for materials, labor, and overhead — ensuring there are no financial surprises later.

  • Scheduling: Building a project timeline that aligns subcontractors, inspections, and material deliveries efficiently.

Good planning is where great projects are born. A GC ensures that when construction begins, everything is in place for smooth execution.

2. Managing the Build

Once the plan is approved and permits are issued, the GC moves into full coordination mode.

  • Hiring and managing subcontractors: From foundation crews to finish carpenters, the GC selects, schedules, and supervises every trade.

  • Procurement: Ordering and tracking materials to avoid costly delays.

  • Site supervision: Overseeing day-to-day progress, maintaining safety standards, and ensuring all work meets building code requirements.

  • Problem-solving: Addressing unexpected site conditions or design changes quickly and professionally.

Essentially, the GC is the bridge between the homeowner, the architect, the trades, and the inspectors.

3. Quality Control and Inspections

Every construction project must pass a series of inspections — framing, electrical, plumbing, mechanical, and final occupancy. The GC ensures each stage meets local building codes and that inspections are scheduled on time.

Beyond passing inspections, a professional GC enforces high standards of craftsmanship. At Nail & Hammer, our fifth-generation carpentry background means we treat every project as a reflection of our name and reputation.

4. Communication and Documentation

One of the most overlooked but critical parts of a general contractor’s job is communication. A good GC keeps the homeowner informed every step of the way.

That means:

  • Regular updates on progress and schedule changes

  • Transparent discussions about cost adjustments or unforeseen issues

  • Detailed documentation of contracts, change orders, and warranties

Construction can be stressful — clear communication keeps everyone aligned and confident.

5. Project Completion and Handoff

When the final inspection passes and the punch list is complete, the GC ensures the client receives:

  • A fully inspected and code-compliant structure

  • Manufacturer warranties and maintenance instructions

  • A final walkthrough to confirm every detail meets expectations

This is where the vision becomes reality — and where a skilled general contractor’s coordination pays off.

Why Hiring a Licensed GC Matters

In Los Angeles, construction regulations are strict for a reason: safety, accountability, and quality. Hiring a licensed general contractor means:

✅ Legal compliance — Your project follows California Building Codes and city ordinances.
✅ Insurance protection — Licensed GCs carry liability and workers’ comp coverage.
✅ Professional accountability — You’re protected by the California Contractors State License Board (CSLB).
✅ Proven experience — A licensed GC understands the permitting, scheduling, and inspection landscape that can otherwise delay projects for months.

An unlicensed builder might seem cheaper up front, but lack of oversight can lead to failed inspections, hidden costs, and liability issues later on.

The Value of a Trusted Contractor

In short, a general contractor is your project’s leader, advocate, and quality guardian. Whether you’re building an ADU, renovating a home, or managing a multifamily investment, your GC ensures that design, budget, and execution align perfectly.

At Nail & Hammer Construction Corp, we take pride in delivering precision craftsmanship backed by decades of experience. We don’t just build structures — we build trust, community, and lasting value for every client.
