How Building an Affinity Modular Home Works

Modular is a type of construction, not a type of home

Affinity manufactures your home. Your local builder manages your complete construction project. Here’s how the two work together.

Affinity Modular = Home Manufacturer
We design, engineer, and construct the modular portions of your home in our controlled manufacturing facility.

Your Authorized Builder / GC = Your Local Home Builder
Your builder manages everything that must happen on your property: permits, site preparation, foundation, utilities, installation, onsite construction, inspections, and getting the home ready for move-in.

You = The Homebuyer
You work with your builder on your overall project. Your builder works with Affinity to design and order the modular portion of your home.

Why do I Need An Authorized Local Builder?

  1. Affinity Modular manufactures the modular portion of your home, but your home is part of a larger construction project that takes place on your property.
  2. The builder coordinates the foundation, permits, site work, utilities, delivery/set, onsite construction, inspections and completion.

What arrives with your Affinity Modular Home

  • Framing
  • Insulation
  • Drywall
  • Electrical
  • Plumbing
  • Cabinets
  • Windows
  • Doors
  • Siding
  • Interior finishes
  • etc.

What still has to happen at your property?

Foundation → crane/set → module connections → utility connections → onsite work → garage/porches/decks → driveway → landscaping → inspections → Certificate of Occupancy.

Welcome Home

Traditional Home Construction

  • Construction takes place entirely on the job site
  • Materials are delivered and stored on-site
  • Weather can impact the construction schedule
  • Multiple trades work sequentially throughout the project
  • Construction debris and site activity continue throughout the build
  • Quality control can vary depending on site conditions and individual trades

Modular Homes at the Factory

  • The home is built simultaneously in a controlled manufacturing environment
  • Materials are protected from weather during construction
  • Multiple trades work together in a coordinated production process
  • Building components are inspected throughout construction
  • Plumbing, electrical, HVAC and other systems are installed as part of the process
  • While the home is being built at the factory, site work can happen simultaneously

Modular Home a Few Hours After Set

  • Modules are delivered and set on the foundation
  • The home is weather-tight much sooner than traditional construction
  • Major structural components are already completed
  • Interior finishes and systems are substantially installed
  • The home begins to look and feel like a finished home almost immediately
  • Site crews transition quickly into finishing and connecting the home

Modular Home a Couple Weeks After Set

  • Exterior and Interior finishing work is progressing rapidly
  • Utilities, connections and remaining site work are completed
  • Remaining trim, finishes and punch-list items are addressed
  • The home is moving toward final inspections and completion
  • The customer can see the finished product much sooner
  • The result is a high quality, precision-built home with a streamlined construction process

Common Homebuyer Questions

No. Affinity Modular is the manufacturer of your modular home. We design, engineer, and construct the modular portions of your home in our manufacturing facility.

Your local Authorized Affinity Builder is the general contractor responsible for your complete homebuilding project. Your builder coordinates the work performed on your property, including permitting, site preparation, foundation, utilities, installation, onsite construction, inspections, and other work required to complete your home.

A simple way to think about it is: Affinity manufactures your home; your builder manages your complete homebuilding project.

Building a modular home involves much more than constructing the home itself. Before your Affinity home can be delivered, your property must be prepared and a foundation constructed. After delivery, the home must be installed, connected to utilities, completed onsite, and inspected.

Your general contractor coordinates all of these parts of the project and the subcontractors involved.

While Affinity is responsible for manufacturing the modular portions of your home, your builder is responsible for turning your property and your Affinity home into a completed, move-in-ready home.

Affinity does not sell homes directly to homebuyers. We manufacture homes for our network of Authorized Affinity Builders.

This is because the home manufactured at our facility is only one part of your overall construction project. A licensed local builder is still needed to manage your property, foundation, permits, utilities, home installation, onsite construction, inspections, and other local requirements.

You can think of Affinity as a highly specialized part of your builder’s construction team. You work with your builder, and your builder works with Affinity.

Your construction agreement is with your local builder, not Affinity Modular.

Your builder is responsible for your overall construction project and incorporates the Affinity modular home into that project. The builder then works directly with Affinity to order and coordinate the manufacturing of your home.

Your builder can explain exactly what is included in your construction agreement and any items that may be outside its scope.

Your local builder provides your pricing and total project estimate. Affinity does not provide retail pricing directly to homebuyers.

The total cost of building your home includes much more than the portion manufactured by Affinity. Costs may include the home, transportation, crane and installation, foundation, site preparation, utilities, permits, onsite construction, porches, garages, driveways, landscaping, and other property-specific work.

Because labor costs, site conditions, building requirements, and the scope of work vary from one property and location to another, your local builder is in the best position to determine your total project cost.

Yes. Before Affinity refers you to an Authorized Affinity Builder, you should have property where you plan to build.

Your property is a key part of planning and pricing your home. Site location, access, zoning, setbacks, foundation requirements, utilities, septic or sewer, grading, and other conditions can affect the feasibility and total cost of your project.

If you’re still searching for property, you’re welcome to explore Affinity home designs and learn more about our building process. Once you have secured your property, contact us so we can help connect you with an Authorized Affinity Builder serving your area.

An Affinity home is typically about 85% complete when it leaves our manufacturing facility.

A significant amount of construction has already taken place indoors before your home arrives at your property. Depending on your home’s design and selections, this can include framing, insulation, drywall, electrical and plumbing components, cabinetry, windows, doors, exterior finishes, and many interior finishes.

However, 85% factory complete does not mean the entire homebuilding project is 85% complete. Significant work must also take place on your property before and after the home arrives.

Once the modules arrive, your builder coordinates the installation of the home onto its permanent foundation and the remaining onsite work.

Depending on your project, this can include connecting and finishing the modules, completing mechanical and utility connections, interior and exterior finish work, porches, decks, garages, steps, driveways, landscaping, and other site improvements.

The home must also complete the required local inspections before it can receive a Certificate of Occupancy.

Your local builder is responsible for coordinating the permits and local inspections required for your project.

Requirements vary depending on the state, county, municipality, and property. Working with a licensed local builder provides someone familiar with the local permitting and inspection process to manage these requirements as part of your overall project.

Affinity handles the approvals and inspections associated with manufacturing the modular portions of the home, while your builder handles the local requirements associated with your property and completed project.

Your local builder is responsible for coordinating the foundation.

The appropriate foundation depends on your home design, property, soil and site conditions, local building requirements, and other engineering considerations.

While your home is being constructed at the Affinity facility, your builder can simultaneously prepare the site and construct the foundation. This ability to perform factory construction and site work at the same time is one of the important advantages of the modular construction process.

Your local builder coordinates the utility connections required for your property.

Depending on your location, this may include electrical service, municipal water and sewer connections, or private systems such as a well and septic system.

These costs and requirements are property-specific, which is another reason your builder, not Affinity, provides your total project pricing.

Possibly, but the contractor must meet Affinity’s requirements and become an Authorized Affinity Builder before constructing an Affinity home.

Affinity homes may only be constructed through approved, licensed contractors who understand our modular construction standards and processes.

If you already have a contractor you would like to work with, contact us to discuss your project and whether that contractor may qualify to work with Affinity.

An Authorized Affinity Builder is a licensed general contractor who has been approved to work with the Affinity modular construction system.

Before becoming an Authorized Affinity Builder, the builder participates in training with Affinity to learn our modular construction process, requirements, and procedures. This helps ensure they understand how to successfully coordinate an Affinity home from the planning stages through completion.

Authorized Affinity Builders work directly with our team throughout the process, from plans and ordering through manufacturing, delivery, installation, and onsite completion.

For the homebuyer, your Authorized Affinity Builder serves as your primary point of contact and manages your overall homebuilding project.

Affinity becomes involved through your Authorized Affinity Builder.

Once you and your builder have established the project and selected or developed a home design, the builder works with Affinity on the plans, engineering, specifications, selections, pricing, ordering, and manufacturing process.

Although our team is involved throughout the modular portion of the project, your builder remains your primary contact for your overall homebuilding project.

It’s perfectly fine to explore Affinity floor plans and start identifying the homes and features you like before selecting a builder.

However, we recommend involving an Authorized Affinity Builder early in the process before making final decisions.

Your property can affect which home designs are practical and what the completed project will cost. Your builder can evaluate factors such as site access, foundation requirements, utilities, setbacks, local building requirements, and site preparation while helping you develop a realistic total project budget.
