    For some, the term Modern Dwelling Unit (MDU) may be new. So let's clear up the confusion by answering one simple question: Are Modern Dwelling Units considered tiny homes?

    The answer: No.

    An MDU is classified as a Park Model RV (PMRV) — a type of recreational vehicle designed for long-term or seasonal living in a semi-permanent location, such as a campground or RV resort.

    At MDU Homes, we offer more than just PMRVs. From micro-units to modular options, we help you find the best fit. Our units meet the ANSI Certification standard with approval from local authorities, ensuring nationally recognized requirements for durability, livability, and mobility.

    How Modern Dwelling Units Exceed Standards

    Tiny homes often mean compromises:

    • Lower ceilings
    • Less privacy
    • Smaller appliances
    • Limited space for entertaining

    MDUs eliminate these issues. At just 399 square feet, each unit is designed for everyday livability — whether for short-term stays or long-term living.

    Every MDU comes fully upgraded because luxury is the standard.

    Features include:

    • Full-size appliances
    • Spacious bathroom
    • Room for a king-size bed
    • Washer/dryer hookups
    • Walk-in shower
    • Open kitchen layout
    • Built-on deck

    Though the footprint is modest, every detail is intentionally designed to maximize comfort and functionality.
