    Signs You Need a Junior ADU in Texas

    Not sure if a Junior ADU is the right fit? Here’s how homeowners know.

    An Aging Parent or Adult Child Needs Independent Space

    You need privacy for everyone, but a full move isn't realistic. A JADU gives them their own entrance and space while staying close to family.

    You Want Rental Income Without a Major Build

    A detached ADU costs more and takes longer. A Junior ADU converts existing square footage into rentable space faster and at lower cost.

    Your Lot Can't Fit a Detached Structure

    Smaller lots or tight setbacks often rule out detached ADUs. A Junior ADU works within your home's current footprint, sidestepping lot-size restrictions.

    Don't Wait — Underused Space Is a Missed Opportunity

    An unused garage or bonus room sitting empty is lost value. The longer it sits unused, the longer you're missing out on income or living space. Call to find out what your space could become.
