Question 1

What is a modular home?

Accepted Answer

A modular home is built in factory modules, transported to site, and assembled on a permanent foundation. It must comply with local IRC building codes like site-built homes and is typically classified as real property.

Question 2

How do modular, manufactured, and site-built homes compare?

Accepted Answer

Modular homes follow local IRC codes and qualify for conventional mortgages. Manufactured homes follow HUD code and are often personal property. Site-built homes follow local codes on site. Modular and site-built typically appreciate; manufactured often depreciates.

Question 3

Can you customize a modular home?

Accepted Answer

Yes. Buyers can customize floor plans, exterior and interior finishes, architectural details, and energy features. Many manufacturers also support architect-led custom designs.

Question 4

How do you finance a modular home?

Accepted Answer

Modular homes on permanent foundations qualify for conventional, FHA, VA, USDA, and construction-to-permanent loans, the same paths as site-built homes when titled as real property.

Question 5

How much do modular homes cost?

Accepted Answer

Total turnkey costs often range from $150,000 to $500,000+ depending on size, finishes, land, site prep, foundation, delivery, and upgrades. Base factory price is typically $80–$200+ per square foot before site costs.

Question 6

How long does it take to build a modular home?

Accepted Answer

Most projects take 3–6 months from order to move-in: design (1–3 months), permits (1–2 months), site prep (1–2 months), factory build (1–2 months), set and finish (2–6 weeks).

Question 7

Are modular homes as durable as site-built homes?

Accepted Answer

Yes, when built and set correctly. Factory construction reduces weather exposure, modules are engineered for transport strength, and inspections occur in-factory and on-site. Lifespan is comparable with proper maintenance.

Question 8

Do modular homes hold their value?

Accepted Answer

Modular homes on permanent foundations generally appreciate like site-built homes because they are real property, meet local codes, and appraise against comparable sales.

Question 9

What site requirements are needed for a modular home?

Accepted Answer

You need delivery access (12–14 ft road width), a prepared foundation, utility connections, zoning approval, suitable soil, and crane/set space. Assess feasibility before ordering.

Question 10

Are modular homes energy efficient?

Accepted Answer

Modular homes can exceed typical site-built efficiency through precise insulation, tighter envelopes, ENERGY STAR options, solar-ready designs, and high-efficiency systems including passive house builds.

Question 11

Are Amazon or Alibaba expandable prefab homes legal to live in?

Accepted Answer

Usually not as dwellings. Most marketplace expandables lack a HUD label or state modular insignia. Some rural counties allow them as sheds. For a legal ADU, use a recognized modular, HUD, or panelized path. See the expandable prefab legality guide.

Question 12

Which prefab ADU company is best in 2026?

Accepted Answer

Match the company to your state and lot. Abodu publishes California turnkey prices. Samara splits unit and install. Studio Shed ships panelized kits nationwide without a crane. Villa covers larger CA and CO layouts. Cover is custom steel in Southern California.

No. Home Nation is an online dealer that quotes delivered factory homes by ZIP. Factories build the unit. Foundation, set, and utilities are usually extra. Confirm HUD versus IRC modular on the data plate before you apply for a loan.
