What is an Junior (JADU)
Built for efficient living
An JADU is a smaller living unit created within the walls of an existing single-family home. For North Texas homeowners, it can be a smart way to add private space for family, guests, or long-term flexibility without building a full detached structure.

What is an Accessory Dwelling Unit (ADU)?
Built for private living
An ADU (Accessory Dwelling Unit) is a secondary, independent living space built on the same property as a main home — it has its own kitchen, bathroom, and sleeping area, but sits on the same lot as the primary house rather than being a separate property.
The defining feature isn’t size or style — it’s that it’s a legally secondary unit tied to a primary residence on one lot, which is what makes it a zoning classification rather than just “a small house.” That’s also why the rules for building one vary heavily by city: some cities allow them by right with a standard permit, while others (like Keller here in your service area) require a Specific Use Permit and City Council-level approval.

Why homeowners choose ADUs
Practical benefits for families
In the current housing market, many homeowners are exploring creative solutions to maximize their property value. ADUs, or Accessory Dwelling Units, have gained popularity due to their versatility and potential for generating additional income. These units can serve multiple purposes: as guest suites, home offices, or even long-term rentals. The flexibility they offer makes them a worthwhile investment for any homeowner looking to expand their living space without the need for extensive renovations.

Colleyville sets its own rules for accessory dwellings, including size, height, setbacks, and how the unit can be used. Those are spelled out in the city’s Land Development Code, and permits are handled by Colleyville Building Inspections. Working through these requirements early prevents costly redesigns later. We handle planning and permitting with the city so your guest house is approved and built to code.
