The mother-in-law suite definition is “an additional living space within your property or home designed for use by your in-laws”. Put another way, it's an additional, fully functional living space added onto a single family home.
These structures are named as such because they're an ideal spot for in-laws to stay in while visiting or to move into when they get older and need extra support and care. Mother-in-law suites are also called in-law suites, granny flats, and mother-daughter houses.
Despite its specificity, the term “mother-in-law suite” is sometimes used interchangeably with “guest house.” That said, guest houses are generally detached from a primary residence, while mother-in-law suites may be attached to it.
A mother-in-law unit is often integrated into the main house. That means it may not have its own entrance like other ADUs. The square footage of an ADU is not added to the square footage of the main house. Most mother-in-law units are part of the overall house and added to its square footage.
Generally, a mother-in-law suite has a bedroom, a full bathroom, a living space, and a kitchen. Ideally, it will have a separate entrance, for the convenience and privacy of the occupant.
Background. Naming conventions vary by time-period and location but secondary suites can also be referred to as an accessory dwelling unit (ADU), mother-in-law suite, granny flat, coach house, laneway house, Ohana dwelling unit, granny annexe, granny suite, in-law suite, and accessory apartment.
According to Porch.com, when ADUs are located on properties in major cities with high housing costs, an ADU can add as much as 35% to the value of a property.
There may be tax credits for having an ADU or in-law suite. For instance, if you're paying for more than half of your relative's support, you may be able to claim them as a dependent. You may also qualify for a home office tax deduction if that's the in-law suite's primary use.
Space Limitations
While they offer a more affordable living option, ADUs can feel cramped and may not be suitable for large families or those who need a lot of space.
An in-law suite is the most common name for a small dwelling on the same property as (and perhaps attached to) a single-family home, where an aging family member (or others) can live with some modicum of privacy and independence.
A granny flat is a small self-contained living space located on the same lot as a primary residence. It is commonly designed to host aging relatives, long-stay friends, or as an income-producing rental unit.
If you know the unit will sit vacant for a while, an in-law unit can be turned into a more traditional rental, with long-term monthly or even yearly leases.
A bedroom in California is typically defined by certain criteria established by local building codes and real estate practices. Generally, a bedroom must have a window for natural light and ventilation, a closet for storage, and sufficient square footage to accommodate a bed comfortably.
Terms such as “master bedroom,” “mother-in- law suite,” and “bachelor apartment” are commonly used as physical descriptions of housing units and do not violate the law.
If you have kids, you'll end up calling your mother-in-law by her anointed grandmother name—Grandma, Gams, GiGi, MawMaw, or Grams—she'll love it. It's great to get on a first-name basis with your mother-in-law. Calling your MIL by her first name is a popular way to go, and most daughter-in-laws do it…
Who Hosts a Baby Shower? Most baby showers should be hosted by a sister, mother, mother-in-law, or close friend. Baby showers were traditionally thrown by family members who weren't close with the parents-to-be, to avoid the assumption that close family members wanted to collect gifts for themselves.
ADU opponents said that ADUs would create parking problems, bring down property values (and generally bring in undesirable people), create overcrowding, change the appearance of neighborhoods, generate noise and garbage, and perhaps end the single-family nature of existing neighborhoods.
A Detached Accessory Dwelling Unit (DADU) involves building a small, single-family residence on a property with an existing residence.
They can be converted garages, basement apartments, or separate cottages. ADUs allow homeowners to expand their living space and generate rentals while maintaining the privacy of both units. On the other hand, tiny houses are compact living spaces intentionally designed to be small and efficient.
Home renovations typically do not qualify for federal tax deductions, but certain improvements may qualify for deductions and credits can help reduce taxes. Financing home improvements through your mortgage may allow you to claim the interest as a mortgage interest deduction.
The potential dependent must be one of these: Your parent, ancestor (ex: grandparent, great-grandparent), or sibling of either of them. Stepsibling, stepparent, parent-in-law, son- or daughter-in-law, or brother- or sister-in-law. Any person that lived with you for the entire year as a member of your household.
The cost of building an in-law suite can vary widely depending on factors such as size, location, materials, and local labor costs. On average, it can range from $50,000 to $250,000 or more.
Approximately 500 to 700 square feet is a good size for an in-law apartment or addition.

Converting a garage into a full in-law or guest suite—or a guest house in the case of a detached garage—costs $20,000 to $50,000 on average. At the lower end of the range, a basic conversion will include insulation, drywall, flooring, and a bathroom.
A mother-in-law is the mother of a person's spouse. Two women who are mothers-in-law to each other's children may be called co-mothers-in-law, or, if there are grandchildren, co-grandmothers.
