The Casita Layouts People Ask For Most
From a quiet guest suite to a rental that earns, these are the configurations we draw most.
A suite under the main roof but with its own door, bath and kitchenette — the simplest and most cost-efficient casita.
A freestanding casita that frames a courtyard with the main house — the classic Southwestern layout that feels like a small compound.
A casita joined to the home by a covered breezeway — connected and weather-protected, but private and quiet.
A self-contained suite sized and zoned to rent nightly, with its own entrance, parking and utilities kept separate from the main home.
A casita off the pool and outdoor living area that doubles as a guest suite and a poolside retreat.
A quiet, separate work-from-home studio or creative space away from the main house, with its own entry and bath.

What Shapes a Casita Plan Before You Draw It
The details that decide whether a casita is a guest room or a real second space.
A separate entrance — and often a courtyard or breezeway between casita and home — is what gives both spaces privacy. How they relate on your lot is the core of the design.
If the casita will earn income, it needs its own entrance, parking and ideally separate utilities. Designing that in from the start is what makes it rentable.
A wet bar and microwave read very differently from a full kitchen — for guests, for long-term family, and for what your locality allows. The plan sets it deliberately.
A freestanding casita is subject to setback and lot-coverage rules. The plan places it where it is both private and compliant.
Whether the casita shares the main service or gets its own — important for a rental — is decided and routed in the plan.
If the casita is for aging parents, a no-step entry and curbless bath keep it usable for the long term.
Why a Casita Is Worth Drawing Custom
A casita is only as good as how it relates to the main house and the lot — and that is precisely what a stock plan cannot solve. Attached or detached, courtyard or breezeway, kitchenette or full kitchen: those choices depend on your site and your goals, and getting them right is the whole point of building one.
Describe how you will use the casita and how your lot sits and our design team delivers a complete print-ready plan set drawn for your home and suite — typically in 7-11 business days with a free revision round included.

A casita adds roughly the cost of a small dwelling — its own bath, kitchenette and entry — but a home with a casita still lands around $140 to $270 per square foot overall in 2026. If it rents, it can pay for itself over time. Knowing the number up front keeps the plan on budget.
A state-adjusted, 14-category cost report prices your build by county, so you can see how the casita size, kitchen and finish level change your cost per square foot.

Design My Plan →Frequently Asked Questions
What is a casita, exactly?
A casita is a small, largely self-contained guest suite — typically a bedroom, a bath, a sitting area and a kitchenette, with its own private entrance. It can be attached to the main house, linked by a breezeway, or fully detached across a courtyard.
Can a casita be used as a short-term rental?
Yes, and many are. To rent well it needs its own entrance, parking and ideally separate utilities, all of which we design in from the start. We also plan it permit-minded, since a rentable casita can be treated as an ADU under your local rules.
How much does adding a casita cost?
A casita adds the cost of a small dwelling — its own bath, kitchenette and entry — but the overall home still runs about $140 to $270 per square foot in 2026. A location-adjusted cost report prices your specific county, casita size and finish.
Can you design the casita around my exact lot?
Yes — that is what our Design Your Dream Home service does. Whether the casita should attach, link by breezeway or stand detached depends on your lot, and a designer draws it around your site and goals from $899, typically in 7-11 business days with a free revision round.
