Questions

Casitas & guest houses questions

What is the difference between a casita and an ADU?

A casita is a small detached guest house. If it has its own kitchen and is permitted as a separate unit, it is an ADU. We help you choose what fits your plans and your city rules.

Can a casita be used as a home office?

Yes. Many owners use a casita as an office or studio, and we can wire it for internet, lighting and heating and cooling.

Do you handle plans and permits?

Yes. We design to your lot and handle plan check and inspections.

Are you licensed and insured?

Yes. Unlimited Construction holds California contractor license #1040445 and is bonded and insured.
