Can I convert my garage into an ADU?

A garage conversion may be an option for creating a separate living space with a kitchen and bathroom. Feasibility depends on the existing structure, utility connections, property conditions, and applicable requirements. XactBuilt can help you explore the design, permitting, and construction involved.

What is the difference between an ADU and a room addition?

An accessory dwelling unit, or ADU, provides independent living facilities, including cooking and bathroom facilities. A room addition expands your existing home, such as adding a bedroom or enlarging a living area. The right choice depends on how you want to use the space and what your property can accommodate.

How much does an ADU, home addition, or remodel cost?

Pricing depends on the project’s size, existing conditions, design, materials, utility needs, and construction scope. A garage conversion, new detached ADU, and kitchen remodel each involve different work. Share your project details with XactBuilt so we can discuss your goals and prepare an estimate based on your scope.

How long does a construction or remodeling project take?

The timeline depends on design decisions, plan preparation, permit review, material availability, and the amount of construction involved. XactBuilt will discuss the anticipated stages and schedule for your project, including the planning and permitting work needed before construction begins.

Does XactBuilt serve Pasadena and Orange County?

Yes. XactBuilt is based in Whittier and serves homeowners in Pasadena, Orange County, and surrounding communities. Include your property’s city when requesting an estimate so we can confirm service availability and discuss your project.
