General Contractor Explained in Plain Language

An oversimplified definition of what a general contractor is would be that they are the gatekeepers for anything to do with the construction process. This is why they are commonly called builders.

There are many common misconceptions about this kind of building contractor, like people thinking of them as one-size-fits-all building contractors.

General Contractor Explained in Plain Language

In addition, if you need any type of repair project or anything associated with real estate, you can just call a general contractor.

It is also common to consider that general contractors are all the same and provide identical services. Both of these misapprehensions are ill-advised.

We will examine the different types of general contractors and discuss the various services that they provide.

We will also offer some insights on how to work through the process of selecting, vetting, and hiring the right building contractor for you. Learn About the Day-to-Day Tasks Describing What a General Contractor Is

General Contractor vs. Subcontractor vs. Architect

A subcontractor is a specialist the GC hires for one trade, such as roofing or wiring. The owner usually does not sign a contract with the subcontractor directly.

An architect or designer draws the plans, while the GC builds them. Firms that offer both under one roof are called design-build contractors.

What are general contractors’ classification types?

There are many different types of building contractors that operate in the construction services industry. There are residential general contractors that offer their services to homeowners, and there are commercial general contractors that service commercial property owners.

 What are General Contractors' Classification Types?

In some cases, these builders cross over and will serve both construction industry sectors. In addition, a building contractor can provide new contracting services and remodeling and renovation services.

Residential General Contractors

A residential general contractor serves homeowners for new home contracting and home remodeling.

New Home Construction Builders

Production Builders
Volume homes
Custom Home Builders
One-of-a-kind homes
Semi-Custom Builders
The hybrid
Build houses in volume. Unique, one-of-a-kind home plans Hybrid of production and custom
4 to 6 models in planned developments Normally larger houses Off-the-shelf design plan
No substantial changes for clients Distinct architectural features Clients can make substantial changes.

These homes take a much longer time to build and commonly require the owner to participate during the contracting process, making decisions and selecting most of the products. This is not the case with production home builders.

Residential General Contractors

Home Remodeling Contractors

A home remodeling contractor is a building contractor that offers home renovations and remodeling services. This type of general contractor comes in a larger variety of construction companies than the home builder segment.

Typical Remodeling Projects
Larger, more complicated home improvement projects
Kitchen remodeling Bathroom remodeling Home additions

This is why they are building contractors – because they hire a large number of subcontractors and material vendors to execute their projects.

But over the years, the descriptive tag representing the home remodeling contractor has been loosely associated with the general home repair and services, also known as the home improvement industry.

Although the home improvement industry crosses over to the home remodeling industry in its project activities, home improvements are distinctively different in one major aspect.

Home improvement construction companies normally are self-performing contractors, performing the skilled trade services with company employees. They do not normally hire a variety of skilled trades to complete a home improvement project.

As you can tell, it can get a bit confusing for a homeowner who wants a major home remodel and has home improvement contractors showing up at their home to view the project instead of home remodeling contractors.

It gets even more confusing when homeowners need home design work done or construction documents prepared. Most remodeling contractors do not prepare these documents or develop home designs.

Design-build contractors are specialty contractors that prepare home designs and facilitate building activities. These types of contractors will take you through the process of home design for new ground-up or remodeling services.

Capture these designs in CAD files and create building documents. From these documents, they can prepare accurate building costs and execute their services.

Commercial General Contractors

Commercial General Contractors

Commercial general contractors provide contracting services to commercial property owners with new ground-up and remodeling service needs.

Like the residential building contractors, they may serve one or both of the industry sectors.

They also operate much like residential general contractors in that they hire subcontractors to perform the skilled trades work and are responsible for both the management and administrative functions of the project.

Although the differences among the building contractors are in the types of property structures they build.

There are a greater number of commercial property structures than there are in home building. There are retail strip centres, medical centres, big box stores, manufacturing centres, and schools.

These projects differ in many regards from residential contracting, but none more than the requirements for life safety in the commercial sector.

Commercial remodeling contractors offer remodeling services and renovations to commercial property owners for many different needs.

From office remodeling to building expansions, commercial remodeling contractors serve a required role in commercial contracting.

Types of General Contractors at a Glance

Here is the general contractor explained by project type. This general contractor summary compares the four main types side by side.

Types of General Contractors at a Glance

Type Who it serves Common projects Owner involvement
Residential (new build) Homeowners and buyers Production, semi-custom and custom homes Low to high, depending on the builder
Remodeling Homeowners Kitchens, baths, additions Moderate
Commercial Business and property owners Retail, medical, schools, offices Moderate
Design-build Owners want one team Design plus construction Moderate, one contract

General Contracting Responsibilities

General contracting is the science of building real estate improvements through construction. The general contractors’ responsibilities consist of both management services and administrative services.

Management Services
Onsite quality control
Administration Services
Back-office activities
Scheduling Accounting
Procurement Financial affairs
Compliance inspections Contracts
Project leadership Accounts payable / receivable
Construction supervision Subcontractor scopes of work
Problem-solving Insurance administration
  Preconstruction: quantity take-offs, estimating, bid proposals

Last but not least, the building contractor is responsible for acting in the best interest of the project and protecting the owner’s interests.

This means openly and regularly communicating with the owner about contracting progress and discussing plan errors and construction issues as they develop.

There should be a high level of professional trust between the owner and builder. The builder should be the owner’s trusted adviser through the design and building journey.

Does Texas License General Contractors?

Texas has no statewide general contractor licence. Electrical and HVAC work is licensed through the Texas Department of Licensing and Regulation, and plumbing through the State Board of Plumbing Examiners.

So ask who holds the trade licences on your job and who pulls the city permit. Our article on why Texas has no state general contractor licence explains more, and you can view Marwood’s Texas contractor credentials.

Permits and Inspections in Houston

Many projects need a permit from the City of Houston Permitting Center. Your GC normally applies for it and schedules the inspections that follow.

HOUSTON EXPERT COMMENT “Owners often think a general contractor simply hires a crew. In truth, the GC is answerable for the schedule, the budget and the quality of every trade on site.”

Benefits of a General Contractor- Managed Project

  •  Mitigates Construction Risk; Protects the project through liability insurance, workers’ compensation, and adherence to safety laws. 
  • Saves Time; Handles the complex coordination of multiple schedules so you do not have to manage trades individually. 
  • Quality Control: Monitors workmanship closely to catch errors early and ensure the final build meets high standards. 
  •  Budget Control: Uses industry networks to negotiate fair pricing on materials and labor, helping prevent costly budget overruns 
  •  Reduces Building Compliance Risk; Provides building code compliance experience for construction inspection and performance standards.
  • Legal Protection: Most accredited GC’s use corporations to avoid legal exposure and carry sufficient insurance.

Selecting a General Contractor

Identifying a small list of general contractors is where the selection process begins. This can be done by researching general contractors online for the relevant service you need.

Study their website, read some of their published articles, and read their client’s reviews. This will provide you with a strong sense if you are interested in working with a general contracting firm such as this.

Start with a phone conversation with each of the builders to see if there is any common ground of interest. Tell them a bit about your project and some of your concerns and see how they respond to you.

Selecting a General Contractor

Are they helpful in their suggestions, and are they like-minded in their ideas? If there is a connection, send them what you have to study and invite them to meet on your project.

Before you meet with them, get yourself prepared beforehand. Outline what is important to you about your future relationship with your builder and what you expect from the building contractor.

Once the meeting takes place, listen to the ideas and remarks the general contractor shares with you.

Are they like-minded in their ideas, or do you like their answers to your questions?

So, what are the best questions to ask a general contractor?

Before you end the meeting, you should request a sample contract and a bid proposal from them. What works is that their proposition should include a set of specific and detailed work detailing their commission and approach in the execution of the labor.

In simple terms, interpret the contract carefully, and if you have any questions, ask them to explain it to you. One word of caution about just using the lowest price as the decisive factor in selecting your building contractor.

The problem with overvaluing the lowest bid price is that if you are not an expert in identifying a complete scope of work, it is impossible to know if you have the lowest price.

The ultimate goal is to find the right general contractor for you. There are many factors to consider, such as price, like-minded philosophy, craftsmanship, completeness of scope of work, contract terms, and business acumen.

It is also important to understand what you expect from your builder and what they can expect from you. Having a positive working relationship with a professional general contractor has far greater long-term benefits than strictly focusing on the lowest price.

Quick Checklist Before You Hire

  • Ask for a written scope of work and bid proposal.
  • Confirm who holds the electrical, plumbing and HVAC licences.
  • Check insurance and call references from recent Houston projects.
  • Compare at least three bids that cover the same scope.
  • Never pay in full up front.
