Features and Layout for ADUs
Size Considerations: The size of an in-law suite can vary greatly depending on the existing structure and the family's specific needs. On average, these suites range from 500 to 800 square feet, providing sufficient space for a comfortable, functional home within a home.
The size of luxury suites in hotels can vary significantly — anywhere between 430 and 4000 square feet (roughly 40 – 372 square metres). In order to qualify as a hotel luxury suite (and not just a deluxe room), it must have at least two separate rooms.
Cost to Build an Attached Mother in Law Suite
If you're converting an existing space in your home into an in-law apartment, you can pay anywhere from $10,300 to $100,000. The price you pay depends on which part of your house you turn into an in-law suite.
Lastly, when it comes to property valuation, an ADU's square footage is not included in the total square footage of the main house.
In-law suites range from 300 to 1,000 square feet. To be considered an accessory dwelling unit, your suite will need to have its own entrance and bathing and cooking facilities. ADUs typically add more value to your home than a repurposed room with an en suite, so it may be worth building a larger unit.
Does a mother-in-law suite add value to a home? In large cities, homes with an ADU are priced 30%-35% higher on average than those without one.
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.
In-Law Suite
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.
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.
This might be because the guest bathroom has things like a toilet and corner sink, a small shower enclosure or are simply small. In general, the dimensions of an average-sized en suite are approximately 2.1m in length and 1.2m in width. These measurements are sufficient for practicality.
Suit sizing is based on your chest measurement. For example, if your chest measures at 40", then you should normally wear a size 40 suit. However, the jacket's chest will measure slightly larger than that (roughly 43") to allow for a comfortable fit, with room for a shirt worn underneath.
It was in the early 17th century that suites with four, five and later six dance movements became the norm, and the keyboard suites of Johann Jakob Froberger (1616-67), with their reliance on four staple dances – allemande, courante, sarabande and gigue – remained a basic pattern for well over a century.
An in-law suite is the most common name for a small, apartment-like space on the same property as, or even attached to, a single-family home. These dwellings are living spaces usually equipped with a bedroom, bathroom, kitchen and a separate entrance from the primary residence.
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.
All of these names refer to the same thing: a secondary living unit within a single family property. This is not to be confused with a guest room, and while tiny houses can sometimes be ADUs, they don't always qualify.
Building a mother-in-law suite could also offer certain tax benefits. How many square feet is a typical mother-in-law suite? Mother-in-law suites can vary in size but are typically about 500 square feet.
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.
Do I need planning permission? Planning permission for a garage conversion is not necessary in many cases, although it is always best to double check with your local authority first.

What Is an ADU? In legal terms, mother-in-law suites are known as accessory dwelling units. Many government agencies offer financial and building assistance to homeowners looking to add a unit that qualifies as an ADU.
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.
