What Does a General Contractor Do? Complete Guide for Homeowners

If you are planning a home renovation, addition, or construction project, you may ask, what does a general contractor do? A general contractor manages and coordinates the different parts of a construction project. They can help plan the work, hire subcontractors, organize materials, manage schedules, coordinate inspections, monitor quality, and communicate with the property owner.

Instead of making the homeowner manage several different trades, the general contractor acts as the main point of coordination. For example, a major home renovation may require a plumber, electrician, carpenter, roofer, drywall installer, painter, and flooring professional. A general contractor helps make sure these trades work in the right order and according to the project plans.

The exact responsibilities can vary by the project, contract, and location. However, the main goal is simple: keep the construction project organized from planning through completion.

What Is a General Contractor?

A general contractor, often called a GC, is a construction professional or company responsible for managing the overall construction work covered by a contract. The GC usually works directly with the property owner and coordinates other workers, subcontractors, suppliers, and construction activities.

A general contractor may manage:

• Residential renovations
• Home additions
• Kitchen remodeling
• Bathroom remodeling
• Basement renovations
• Structural improvements
• Exterior renovations
• Roofing projects
• Masonry work
• New construction
• Commercial construction and improvements

The contractor does not necessarily perform every task personally. Specialized work is often completed by subcontractors with experience in specific trades. For example, an electrician handles electrical work while a plumber handles plumbing. The general contractor coordinates when these workers arrive, what they need, and how their work connects with the rest of the project.

What Does a General Contractor Do?

A general contractor can have many responsibilities before, during, and after construction. The most common duties include:

1. Planning the project
2. Preparing or reviewing cost estimates
3. Hiring subcontractors
4. Scheduling construction work
5. Ordering and coordinating materials
6. Managing permits and inspections
7. Supervising job-site activities
8. Monitoring workmanship and quality
9. Communicating with the property owner
10. Managing changes and unexpected problems
11. Coordinating project completion
12. Handling final inspections and punch-list work

The contractor’s exact role depends on the agreement with the property owner. Some GCs perform certain construction tasks with their own crews, while others subcontract most specialty work.

1. Project Planning

Good construction starts before anyone begins working on the property. A general contractor reviews the project scope, plans, drawings, materials, and expected work. They determine what needs to happen and in what order.

Planning may include:

• Reviewing architectural drawings
• Understanding the scope of work
• Identifying required trades
• Estimating labor needs
• Planning material deliveries
• Developing a construction schedule
• Identifying possible problems
• Coordinating with architects or designers

This early planning helps reduce confusion once construction begins. For a remodeling project, the contractor may also identify existing conditions that could affect the work. An older home, for example, may have outdated plumbing, electrical systems, or structural issues that need attention.

2. Creating and Managing the Budget

Construction costs involve much more than the price of materials. Labor, equipment, permits, subcontractors, deliveries, demolition, disposal, and other project expenses can all affect the final cost. A general contractor helps develop and manage the construction budget.

They may:

• Estimate labor costs
• Estimate material costs
• Request subcontractor pricing
• Compare supplier prices
• Track project expenses
• Identify potential cost changes
• Communicate budget changes to the owner

A good contractor should also explain changes that may affect the original price. Unexpected conditions can sometimes increase costs. For example, removing an old wall could reveal damaged framing or plumbing problems that were not visible before demolition. The contractor can explain the issue and discuss the available options with the property owner.

3. Hiring and Coordinating Subcontractors

One of the most important general contractor responsibilities is managing specialty trades. A larger project may involve several subcontractors, including:

• Electricians
• Plumbers
• HVAC technicians
• Roofers
• Masonry contractors
• Carpenters
• Drywall installers
• Flooring installers
• Painters
• Siding installers

The general contractor coordinates these workers so their tasks fit together. For example, electrical and plumbing rough-ins may need to be completed before walls are closed. Drywall cannot be installed properly if major work behind the walls is unfinished.

The GC creates an organized sequence so one trade does not interfere with another. This is one of the biggest advantages of hiring a general contractor for a multi-trade project.

4. Managing the Construction Schedule

Construction has a natural sequence. For example:

Planning → permits → demolition → framing → plumbing/electrical → insulation → drywall → flooring → painting → fixtures → final inspection

Not every project follows exactly this order, but many activities depend on earlier work being completed. A general contractor creates and manages the project schedule. They coordinate when workers should arrive and when materials need to be delivered.

If a material is delayed or a subcontractor cannot start on time, the contractor may adjust the schedule to reduce the impact on the project. Effective scheduling is important because delays in one part of the project can affect several other trades.

5. Managing Permits and Inspections

Some construction and remodeling projects require permits and inspections. The exact requirements depend on the project and local jurisdiction. A general contractor can help determine what approvals may be required and coordinate the appropriate inspections.

For Maryland homeowners, licensing and regulatory requirements are particularly important. The Maryland Home Improvement Commission regulates home improvement contractors, and Maryland requires contractors who enter into home improvement contracts with homeowners to hold the appropriate MHIC license.

It is also important to understand that Maryland’s MHIC license does not cover new home construction. The Maryland Home Improvement Commission states that builders constructing new homes must be registered through the state’s Home Builder Registration Unit. Because requirements can depend on the project and location, homeowners should verify applicable rules before construction begins.

6. Supervising Construction Work

A general contractor does not simply hire workers and leave them alone. They oversee the work to make sure the project is moving according to the plans, specifications, schedule, and contract. Site supervision may involve:

• Checking completed work
• Coordinating subcontractors
• Reviewing material deliveries
• Identifying problems
• Addressing construction conflicts
• Monitoring job-site conditions
• Communicating progress to the owner

The contractor may also coordinate inspections and help resolve issues discovered during the construction process. The goal is to identify problems early rather than waiting until the project is almost finished.

7. Managing Materials and Deliveries

Materials need to arrive at the right time. If drywall arrives too early, it may take up valuable space on the job site. If it arrives too late, the next stage of construction may be delayed.

A general contractor can coordinate material orders and deliveries based on the construction schedule. Depending on the project, this may include:

• Lumber
• Drywall
• Roofing materials
• Siding
• Flooring
• Cabinets
• Doors
• Windows
• Plumbing fixtures
• Electrical materials
• Masonry materials
• Paint and finishing products

Managing materials also helps reduce unnecessary delays and confusion.

8. Quality Control

A general contractor also pays attention to the quality of the work. Quality control can include reviewing workmanship, checking installations, identifying defects, and making sure completed work meets the project’s requirements.

For example, during a bathroom renovation, the contractor may need to coordinate waterproofing, plumbing, electrical work, tile installation, ventilation, and finishing. These tasks need to work together.

A problem hidden behind a finished wall can be expensive to correct. Checking work at the appropriate stages can help catch issues before they become larger problems.

9. Communication With the Property Owner

Construction projects involve many decisions. The property owner may need to choose materials, approve changes, review costs, or make decisions when unexpected conditions appear.

The general contractor is often the main point of contact. Instead of the homeowner calling several different trades, they can communicate with the contractor who is coordinating the project. Good communication should cover:

• Project progress
• Upcoming work
• Schedule changes
• Material selections
• Unexpected problems
• Cost changes
• Inspection results
• Completion dates

Clear communication can make a complicated project easier for the homeowner to understand.

10. Solving Problems During Construction

Construction rarely goes exactly according to the original plan. A contractor may discover:

• Hidden water damage
• Damaged framing
• Outdated wiring
• Plumbing problems
• Structural concerns
• Material delays
• Unexpected site conditions

A general contractor helps determine what needs to happen next. The solution may require bringing in a specialist, changing the sequence of work, ordering different materials, or discussing a change in scope with the property owner. The contractor’s ability to coordinate these decisions can help keep the project moving.

What Services Does a General Contractor Provide?

The services offered by a general contractor depend on the company and project. For residential construction, services may include:

Home Remodeling

This can include kitchen remodeling, bathroom renovations, basement improvements, interior renovations, and larger home remodeling projects.

Home Additions

A home addition may require foundation work, framing, roofing, insulation, electrical, plumbing, drywall, flooring, and finishing. A general contractor can coordinate these different stages.

Interior Renovation

Interior projects can include changes to kitchens, bathrooms, bedrooms, living areas, flooring, walls, ceilings, and other interior spaces.

Exterior Renovation

Exterior construction may include roofing, siding, masonry, paving, exterior repairs, and other property improvements.

Structural Work

Projects involving wall removal, room additions, structural repairs, or changes to the building structure require careful planning and coordination.

Commercial Construction

General contractors can also coordinate construction and renovation work for commercial properties. These projects may involve larger teams, more complex schedules, and additional project requirements.

General Contractor vs. Subcontractor

A general contractor and a subcontractor have different roles.

General Contractor	Subcontractor
Manages the overall project	Handles a specific trade
Coordinates multiple workers	Focuses on specialized work
Manages the project schedule	Works according to the project schedule
Communicates with the property owner	Usually reports to the GC for project coordination
Coordinates materials and trades	Provides trade-specific labor and materials
Helps manage inspections and project requirements	Completes work within their specialty

For example, an electrician may install wiring throughout a renovation. The general contractor coordinates when the electrician works and makes sure the electrical work fits with framing, plumbing, drywall, and other stages.

This distinction is important because homeowners sometimes assume that a general contractor personally performs every part of construction. That is not always the case.

General Contractor vs. Construction Manager

The terms general contractor and construction manager can sometimes overlap, but they are not always the same role. A general contractor typically manages construction work and contracts with subcontractors as part of the project’s delivery structure.

A construction manager may provide project management and coordination services under a different arrangement. The exact responsibilities depend on the contract and construction delivery method.

For homeowners, the important question is not only the job title. Ask what services the professional will actually provide and who will be responsible for subcontractors, permits, scheduling, and project coordination.

When Should You Hire a General Contractor?

You may not need a general contractor for every small home repair. For example, replacing a single fixture may only require a qualified specialist. A general contractor becomes more useful when a project involves several trades or construction stages.

Consider hiring one for:

• Major home renovations
• Complete remodeling
• Home additions
• Structural changes
• Large bathroom renovations
• Kitchen remodeling involving several trades
• Basement renovations
• Major exterior renovations
• Projects requiring several subcontractors
• Large commercial improvements

The more moving parts a project has, the more valuable professional coordination can become.

What Are the Benefits of Hiring a General Contractor?

Hiring a general contractor can simplify a complex construction project.

One Main Point of Contact

Instead of managing several companies, you have one primary person or company coordinating the work.

Better Scheduling

The contractor coordinates trades so work happens in the appropriate sequence.

Easier Project Management

The GC handles many of the day-to-day details that would otherwise fall on the property owner.

Subcontractor Coordination

The contractor can coordinate specialty workers and suppliers.

Permit and Inspection Assistance

Depending on the project, the contractor can help manage permit and inspection requirements.

Problem Solving

When unexpected issues appear, the contractor can coordinate the next steps.

Quality Oversight

The contractor can monitor completed work and address problems during construction.

How Do You Choose a General Contractor?

Choosing the right contractor is an important part of the project. Before hiring one, ask about:

• Experience with similar projects
• Required licenses
• Insurance
• References
• Written contracts
• Project timeline
• Payment schedule
• Subcontractors
• Permits
• Change orders
• Warranty or post-project support

In Maryland, homeowners can also verify contractor licensing through the Maryland Home Improvement Commission. The state provides resources for checking contractor license status and understanding home improvement requirements.

Do not choose a contractor based only on the lowest price. A very low estimate may not include the same scope of work, materials, preparation, or project management as another estimate. Compare the details of each proposal.

How Does a General Contractor Get Paid?

General contractors may use different pricing structures depending on the project. Common arrangements include:

• Fixed-price contracts
• Cost-plus contracts
• Time and materials
• Percentage-based arrangements

The contract should clearly explain the scope of work, payment schedule, allowances, change orders, and other important financial terms. Before signing, make sure you understand what is included and what could result in additional charges.

Do General Contractors Do the Physical Work?

Sometimes, but not always. Some general contractors have their own crews and personally perform certain construction tasks. Others rely heavily on subcontractors for specialized work.

For example, a contractor may have an in-house carpentry crew but hire licensed electricians and plumbers for specialized systems. The important role of the GC is managing the overall project, whether the work is performed by their own team or subcontractors.

General Contracting in Maryland

Maryland homeowners should pay close attention to licensing and project requirements when hiring a contractor. The Maryland Home Improvement Commission states that home improvement work includes alteration, remodeling, repair, or replacement of a residential building or part of one.

Maryland also has specific rules about who may contract directly with homeowners for home improvement work. The state says only MHIC-licensed contractors may enter into contracts with homeowners to perform home improvement work. Requirements can differ for new home construction and other types of projects, so homeowners should confirm the applicable requirements for their specific job.
