Same thing, different name
Granny flat = ADU.
"Granny flat," "in-law unit," "casita," "backyard cottage" — they all mean the same thing: a fully independent second home on your property, with its own kitchen, bathroom, and private entrance. The permitting and construction are identical to any ADU under California law.
For family
Keep loved ones close.
Independence and privacy for aging parents or adult kids — without sacrificing proximity or care.
For income
Steady rental upside.
Rent it out for monthly income, or live in it and rent the main house. A permitted unit adds real value.
For flexibility
Adapts over time.
Guest house today, rental tomorrow, downsizing destination later. One build, many uses.

Questions
Granny flat questions, answered.
Still have a question? Ask us during your free consultation.
Is a granny flat the same as an ADU?
Yes. "Granny flat," "in-law unit," "casita," "backyard cottage," and "second unit" are all everyday names for an Accessory Dwelling Unit (ADU) — a self-contained second home on your property with its own kitchen, bath, and entrance. The rules, permitting, and construction are identical to any ADU under California law.
Can I build a granny flat for an aging parent in Los Angeles?
Absolutely — multigenerational living is one of the most common reasons LA homeowners build. A granny flat keeps family close with independence and privacy, and California ADU law makes it far easier than it used to be: streamlined approvals, no added parking in many cases, and ministerial (no-hearing) permitting.
How big can a granny flat be?
Detached granny flats can typically be up to 1,200 sq ft (or 50% of your home's footprint for attached units), with studios and JADUs as small as ~350–500 sq ft. We'll recommend a size that fits your lot, your family's needs, and your budget.
How much does a granny flat cost in LA?
It depends on size, type, and finishes. Converting an existing garage is the most affordable path; a detached new-build costs more but adds the most value and privacy. Use our ADU cost calculator for a quick estimate, or book a consultation for a real all-in number for your lot.
Can I rent out my granny flat?
Yes. Many homeowners build a granny flat for family first, then rent it later (or vice versa) for steady income. A permitted ADU also adds documented square footage and value to your property.
Do you design and build granny flats, or just one or the other?
Both. We handle design and permitting in-house and build with vetted, licensed contractors — so you get one accountable team from first sketch to move-in. We've delivered 600+ ADUs across Greater Los Angeles.
