What Does a General Contractor Do?

What does a general contractor do? Simply put, the general contractor is the primary source of contact for your building project and takes care of everything from the first phone call to the last tour.

This beginner’s guide for general contractors and homeowners identifies the tasks carried out by general contractors on a daily basis in simple terms that are easy to understand.

On paper, it looks pretty simple. Call the plumber, find the electrician, maybe an experienced carpenter. How hard can this be?

Then the quotes come back all over the place, trades don’t show up when they said they would, and the schedule starts slipping before the first wall comes down.

A general contractor is what stops this from happening. They keep every trade on track, monitor the pace of the job, and intervene at the very moment anything appears to be going wrong 

This guide covers the general contractor duties explained at a beginner level: what a GC actually does day to day, how the role works in Houston specifically, and when you actually need one. For the deeper, service-level breakdown of how Marwood Construction manages full projects, see our main general contracting services page.

What Is a General Contractor?

The person in charge of the contractor fielding out all the pieces of the construction puzzle without letting them fall apart is known as a general contractor.

Schedules shift. Materials show up late. A tradesman doesn’t answer their phone. The GC takes all of that and keeps it moving in a straight line, so you’re not the one chasing down the electrician or calling the tile installer for the fourth time.

Part manager, part negotiator, part referee – those are the job description in three words.

Different types of general contracting work can be divided into three big areas: residential (which includes work on homes, kitchens, bathrooms, and extensions), commercial (which includes offices, retail shops, and restaurants), and industrial (which covers plants and factories).

General contractors involved in residential projects typically operate with smaller teams and do renovations directly with homeowners.

“Commercial general contractors”, on the other hand, deploy bigger teams and handle more jobs at once, as well as having many more documents and paperwork to complete. When it comes to office projects, retail buildings, and restaurants, all of them follow stricter life-safety and accessibility regulations than the residential sector.

Industrial contractors are involved in the biggest projects such as building power plants and oil refineries.

General Contractor Daily Responsibilities: What GCs Manage Day to Day

People looking for a general contractor’s responsibilities are usually wanting one simple answer: the list of things that happen on a day-to-day basis. This is what GCs do on normal residential construction, grouped into categories of importance.

In addition to fulfilling its daily schedule, a general contractor’s functions include various important areas starting with the very first discussion and ending with inspections.

The responsibilities in this regard may include on-site and off-site project management activities, e.g., safety management and project licensing.

Project Oversight: Planning, Permits, and Inspections

In the case of the general contractor, there is no vague idea of what is about to be done, only a detailed plan negotiated with every partner.

This includes all approval documents, permits, and schedules of inspections in relation to different construction stages.

Missing one inspection can lead to halting the project until getting approval.

Subcontractor Hiring and Management

Finding reliable workers is a risk for someone because the workers may vanish after completing only part of the job.

However, those general contractors already have a group of trusted workers specialised in various fields.

They usually take care of the schedule, preventing workers of different trades from working on the same day.

If something is wrong with the work of the subcontractor, the GC will deal with the issue personally, while the homeowner is not engaged in the process.

Budget and Cost Control

In any construction project, money flows away quickly, normally for a combination of small reasons without a single major mistake. 

The general contractor has to estimate the cost of materials, find suitable suppliers, and control expenses closely

As a general contractor who knows his job well, he will estimate the extra costs ahead to compensate for any unforeseen spikes in material prices.

Thanks to this estimate, the project will continue without the need to renegotiate its budget every time a material pops up at a higher price.

Safety and Compliance

The general contractor ensures that health regulations are followed for the sake of safety; the workers use scaffolding and special protective equipment, and only licensed workers will perform the electrical tasks.

He also has liability insurance, which will ensure compensation of losses in case of any unforeseen incident.

Daily Site Supervision

Construction demands a specialist to be on the construction site for quality assurance and timely detection of issues on a construction site.

The construction manager takes charge of the day-to-day production process, maximising efficiency by solving delivery issues or supervising subcontractors.

Communication and Reporting

Generally, a contractor can provide necessary communication between the homeowner, the architect, and all the people working on the site.

Instead of having to make five different calls to get updates about the work process, delays, and budget, the individual makes one phone call and gets all the required information.

Many reputable construction companies offer a contingency solution that is planned beforehand to mitigate the potential risk of delays.

Did You Know? According to the U.S. Bureau of Labour Statistics, the job of the construction manager (a classification that includes practically all general contractors) includes planning, directing, budgeting, and controlling construction projects from beginning to end. It is anticipated that positions will continue to be created in this profession across the country in the next ten years.

The Role of a General Contractor in Houston

The role of a general contractor Houston homeowners rely on carries a few local wrinkles that a national guide won’t cover.

The first step of every structural job is getting a permit through the Houston Permitting Center, the agency which reviews the plans and makes the necessary inspections of a project. Skipping this step is illegal and could halt a project in the middle of building.

Houston’s clay soils contribute to the fact that foundation issues are more prevalent here than in any other region of the U.S., so it is vital for an experienced local general contractor to watch out for any movements before finishing the building.

The influence of hurricane code regulations, high humidity affecting the materials, and the notion of drainage connected to floodplain zones is also indicative of the necessity for local experience.

It is also important to say that Texas does not need a general contractor’s licence, which entails that it is needed to be sure about the insurance, references, and successful experience before the contract is signed. See our Houston service areas page for the neighbourhoods we work in most often.

Houston’s permitting timeline can also shift depending on the neighbourhood. Historic districts and certain HOAs layer their own review process on top of the city’s, which is another reason local GC experience saves time.

A contractor who has already pulled permits in River Oaks, Memorial, or the Heights knows the local quirks before they become a delay on your project.

GC Role on a Construction Project: From Planning to Final Inspection

Understanding the GC role on a construction project is easier when you see it broken into phases instead of one long list of tasks.

Expert Insight “Homeowners usually picture the finished kitchen, not the fifteen phone calls that happen before the first cabinet goes in. That coordination work is the actual job; the build itself is almost the easy part.” Patrick Martin, CEO, Marwood Construction LLC (45+ years of Houston construction experience)

Do You Need a General Contractor for Every Project?

In case of minor jobs like replacing lights or painting a room, you will most likely not require help from a general contractor and will do everything yourself. However, when it comes to a job that requires the involvement of several trades, such as getting permits or coordinating schedules, you will face complications when you decide to be your own GC and will have to deal with all issues when something goes wrong with a subcontractor’s task. 

For a rebuilding project requiring multiple inspections or involving many trades, it is already clear who to get to do the job, how to deal with any obstacle standing in the way of receiving necessary permits, and how to manoeuvre between workers. 

The truth is that below are some signs that it is time to hire a general contractor rather than doing the task by yourself:  

• The job requires several workers (in the fields of plumbing, carpentry, and electrical works) to complete the given project.
• The project has to be inspected or needs special permits.
• You don’t have time to coordinate deliveries, schedules, and daily site checks yourself.
• The budget is large enough that a scheduling mistake would be expensive to fix.

What Does a General Contractor Cost in Houston?

Fees are usually a percentage of the total project, generally landing somewhere in the 10–20% range depending on project size and complexity.

For a full breakdown of budgeting, financing options, and Houston cost ranges by project type, see our detailed guide: How to Budget for a Home Remodel in Houston.

That fee typically covers scheduling, subcontractor management, permitting, and the risk the GC takes on by standing behind the finished work; it isn’t just a markup on materials.

Smaller single-trade projects sometimes land on the higher end of that percentage range because overhead costs stay roughly fixed regardless of project size.

Larger whole-home projects often land toward the lower end of the range, since the fee gets spread across a bigger overall budget.
