Can I Build Modular in My City? What to Know Before You Start

Modular homes are faster, more efficient, and increasingly seen as part of the solution to America’s housing crisis. But before you dive into floor plans and finishes, there’s a more fundamental question that needs answering:

👉 Can you actually build modular in your city—or on your specific lot?

At TMOD™, we start every project with a deep feasibility review because modular success starts with understanding local rules, site conditions, and zoning constraints. Here’s what you need to know before moving forward.

🏛️ 1. Modular Is Legal—But Local Rules Still Apply

Modular homes are built to IRC code (International Residential Code) and are considered real property—just like a site-built home. That means yes, you can build modular in most jurisdictions.

But that doesn’t mean you can place a modular home anywhere. Cities and counties still regulate:

• Zoning and land use (single-family, ADU, multifamily)

• Setbacks, lot coverage, and building height

• Design review and architectural guidelines

• Foundation requirements

• Utility hook-up regulations

• Delivery and crane logistics (especially in tight neighborhoods)

🧭 2. Zoning and Use Are Key

The most important first step is reviewing your lot’s zoning designation. That determines:

• Whether a primary residence or accessory dwelling unit (ADU) is allowed

• If there are density caps or restrictions on multiple units

• What type of home (single-family, duplex, cottage court, etc.) is permitted

TMOD™ reviews your zoning and overlays during our feasibility process and helps you match the right modular plan to your lot’s capabilities.

🛣️ 3. Modular Delivery and Access Can Be a Dealbreaker

Even if your city allows modular homes, delivery access can stop a project cold if it’s not planned for. We assess:

• Road width and grade

• Overhead power lines or tree clearance

• Turn radius for the transport truck

• Staging space for the crane and modules

Our team uses site modeling and aerials to simulate delivery and placement before you ever commit to a build.

🧱 4. Know What’s Built On-Site vs. In-Factory

Cities want clarity on what’s modular (built off-site) and what’s site-built. Common site-built elements include:

• Foundations

• Porches, decks, and stairs

• Detached garages or carports

• Driveways and sidewalks

• Final utility connections

We provide clear 3D visuals to help cities and planning departments understand the full scope.

📄 5. Some Cities Still Don’t Understand Modular—We Help You Educate Them

Despite modular being code-compliant, some local officials still confuse it with manufactured or mobile homes. That confusion can lead to delays or rejections.

At TMOD™, we provide:
✅ 3D visualizations of your home on your lot
✅ Clarified documentation of code compliance
✅ Support letters and reference projects
✅ Communication with planning/zoning staff as needed

We’ve helped clients gain approvals by showing—not just telling—what modular really is.

✅ The Bottom Line: Yes, You Probably Can—But Don’t Skip the Research

Modular is legal in all 50 states. But every city is different, and every site has its own constraints. Before you get emotionally or financially committed, make sure your site is truly modular-ready.

That’s why our feasibility study is the first step in every TMOD™ project. It’s how we protect your time, your investment, and your vision.
