What Is a General Contractor? When Do You Need One vs Hiring Subcontractors Directly?

If you are planning a remodel, home addition, casita, or custom home project in New Mexico, one of the first questions you may ask is:

“Do I need a general contractor, or can I hire subcontractors myself?”

For many homeowners in Albuquerque, New Mexico, Rio Rancho, New Mexico, and throughout New Mexico, construction can feel confusing because there are so many different trades involved:

• Electricians

• Plumbers

• Framers

• Roofers

• Tile installers

• Drywall crews

• Painters

• HVAC contractors

• Flooring installers

Many people assume hiring each subcontractor directly will save money.

Sometimes it can.

But in larger construction projects, hiring a licensed general contractor often saves homeowners significant time, stress, mistakes, delays, and unexpected costs.

Understanding the difference between a general contractor and subcontractors can help homeowners make better decisions before starting a construction project.

What Is a General Contractor?

A general contractor (GC) is the licensed professional responsible for managing and coordinating an entire construction project.

Think of the general contractor as the project manager, organizer, and construction leader responsible for making sure every part of the project works together correctly.

A licensed general contractor typically handles:

• Project planning

• Scheduling subcontractors

• Permits and inspections

• Material coordination

• Construction sequencing

• Budget management

• Communication with the homeowner

• Quality control

• Problem-solving during construction

The general contractor oversees the entire project from demolition to final completion.

What Are Subcontractors?

Subcontractors are specialized trades hired to complete specific portions of a project.

Examples include:

• Plumbers

• Electricians

• HVAC installers

• Roofers

• Concrete contractors

• Flooring installers

• Tile contractors

Most subcontractors focus only on their trade.

For example:

• A plumber handles plumbing systems

• An electrician handles electrical work

• A roofer handles roofing

They usually do not manage the overall project.

When Can You Hire Subcontractors Directly?

Hiring subcontractors directly may work well for smaller, isolated projects such as:

• Replacing flooring

• Painting a room

• Installing countertops

• Minor plumbing repairs

• Replacing windows

• Small electrical upgrades

In these situations, there may only be one or two trades involved, making coordination relatively simple.

Some homeowners successfully manage these projects themselves.

When Do You Need a General Contractor?

A general contractor becomes far more valuable when multiple trades, permits, inspections, or structural changes are involved.

Projects that usually require a general contractor include:

• Kitchen remodels

• Bathroom remodels

• Full home renovations

• Home additions

• Casitas and ADUs

• Garage conversions

• Structural wall removal

• Custom home construction

• Commercial tenant improvements

Once a project involves scheduling multiple subcontractors in the correct order, construction management becomes significantly more complex.

Why Construction Sequencing Matters

Construction projects must happen in the correct order.

For example, in a bathroom remodel:

1. Demolition happens first

2. Framing modifications occur

3. Plumbing rough-in is completed

4. Electrical rough-in is installed

5. Inspections are scheduled

6. Drywall or backer board is installed

7. Waterproofing is applied

8. Tile work begins

9. Cabinets and fixtures are installed

10. Final inspections occur

If trades are not coordinated properly:

• Delays happen

• Materials arrive at the wrong time

• Inspections fail

• Work must be redone

• Costs increase

A good general contractor manages this entire process.

What Does a General Contractor Cost?

One of the biggest misconceptions homeowners have is:

“The contractor is just adding extra cost.”

In reality, a general contractor is managing risk, logistics, scheduling, permits, coordination, and liability.

General contractors are typically paid in one of several ways:

Fixed Price Contract

The contractor provides one complete project price.

This is common for:

• Remodels

• Additions

• Casitas

• New construction

Cost Plus Contract

The homeowner pays:

• Actual construction costs

  PLUS

• A contractor management fee or percentage

This is common in:

• Large renovations

• Luxury homes

• Custom construction projects

Percentage-Based Markup

Some contractors charge a percentage for managing subcontractors and materials.

Typical ranges may vary depending on:

• Project complexity

• Size

• Risk

• Coordination requirements

Why Hiring a General Contractor Often Saves Money

Many homeowners try to self-manage projects to reduce costs.

Sometimes this works.

But many homeowners underestimate:

• Scheduling complexity

• Permit requirements

• Inspection coordination

• Material lead times

• Building code compliance

• Construction sequencing

Mistakes often become expensive.

Common problems include:

• Failed inspections

• Incorrect installations

• Contractor no-shows

• Project delays

• Material waste

• Rework due to poor coordination

In many cases, homeowners spend more fixing problems than they would have spent hiring a professional general contractor from the beginning.

What Is the Value of a General Contractor?

A good general contractor provides value far beyond labor.

They provide:

Project Management

Coordinating every phase of construction.

Experience

Recognizing problems before they become expensive.

Permit & Inspection Management

Ensuring work complies with local building codes.

Trade Coordination

Scheduling subcontractors efficiently.

Accountability

One point of contact responsible for the project.

Quality Control

Ensuring workmanship meets professional standards.

Risk Reduction

Helping avoid costly mistakes and construction failures.

What Should Homeowners Expect From a General Contractor?

A professional contractor should provide:

• Clear communication

• Detailed written estimates

• Licensing information

• Insurance documentation

• Realistic timelines

• Transparent expectations

• Organized scheduling

• Written contracts

• Permit guidance

Homeowners should never feel confused about:

• Scope of work

• Pricing

• Timeline

• Responsibilities

A good contractor explains the process clearly.

How Do You Find a Good General Contractor?

Choosing the right contractor is one of the most important decisions in construction.

Homeowners should look for:

Proper Licensing

Verify the contractor holds the correct state license.

In New Mexico, this may include:

• GB-98 General Contractor licensing

Insurance & Bonding

Always verify:

• General liability insurance

• Workers compensation coverage

• Bonding status

Detailed Estimates

Professional contractors provide written scopes of work—not vague verbal pricing.

Reviews & Reputation

Look for:

• Google reviews

• BBB profiles

• Local reputation

• Previous project photos

Communication

If communication is poor before the project starts, it usually becomes worse during construction.

Experience With Similar Projects

A contractor experienced in:

• Kitchens

• Bathrooms

• Additions

• Casitas

• Custom homes

will better understand project challenges.

The Cheapest Contractor Is Not Always the Cheapest Project

One of the biggest mistakes homeowners make is comparing estimates only by price.

Two contractors may appear to offer “the same remodel” while including completely different scopes of work.

Lower bids often exclude:

• Permits

• Waterproofing

• Proper preparation

• Quality materials

• Licensed subcontractors

• Structural corrections

Unfortunately, homeowners often discover these missing items after construction problems begin.

Final Thoughts

Hiring a general contractor is ultimately about reducing stress, improving organization, and protecting the long-term success of a construction project.

For small single-trade projects, homeowners may be able to hire subcontractors directly.

But once projects involve:

• Multiple trades

• Structural work

• Permits

• Scheduling

• Inspections

• Major renovations

a licensed general contractor often becomes one of the most valuable investments in the entire project.
