Tips to Building the Perfect In-Law Suite - How Big? What's the Cost?

What exactly is an In-Law Suite?

According to the 2000 Census, there are at least 3.9 million American families who have at least 3 generations living in one household.  

So Mom, Dad, Grandma, and Joey and Jen all share a cozy home.   Sometimes this is temporary - maybe Joey went to college, moved out, but came back after he graduated so that he could save for his own home. 

Or maybe it was a mutual decision that Grandma should move in - she loves watching the young kids, saves on expenses, and since she doesn't get around as well as she used to, her support group is right down the hall. 

An In-Law Suite is a planned area for additional adults to share living space on a temporary, semi-permanent, or permanent basis.  It can be:

  • A bedroom with a full bath attached.
  • A bedroom with a sitting room near a full bath.
  • A small "apartment" which may have a bedroom and a living room/kitchenette combination.
  • A suite with a separate entrance.

Will you be allowed to build a full in-law suite?

Before deciding to include a full suite in your next home, check on the area building codes.  Some areas don't allow a second kitchen or a "rentable unit" on some lots.

Are you planning to sell your home?

If you're planning to sell your home someday (which most of us will, within 5-7 years of the purchase of the home), think about the type of suite that a potential buyer will want.  In most cases, an in-law suite that consists of just a bedroom with a private bath, downstairs if possible, will be most desirable - because they offer a multitude of uses.

A downstairs bedroom with full attached bath can be:

  • A place for a partner to recuperate from illness.
  • A great guest room.
  • A quiet and convenient office or study.
  • A place for Grandma and Grandpa to stay for three months without having to climb the stairs - or interrupt the upstairs sleeping habits.

Adding a full attached bathroom to a downstairs bedroom can add some cost.  If your septic permit only allows three bedrooms - and those are all upstairs - you may need to pay for an expanded system, which can add 25-75% to the septic cost. 

An additional full bath can add at least several thousand to the cost of the home, depending on whether you prefer tile and premium cabinets, or a more typical vinyl floor and fiberglass tub.  It's more typical to see a half bath downstairs. 

But the cost of adding a full suite with kitchenette can be significant.  There will be kitchen appliances, plumbing, countertops, lots of cabinets, and simply the cost of the additional square footage to consider.  And keep in mind, you may not get that cost back when you go to sell your home - unless you are building at a luxury level and can market the rooms as a "Nanny living suite" - which is another great use for an In-Law Suite.

If you can't find the perfect floor plan, talk to a custom home builder. 

A custom home builder may be able to expand a bathroom, add a separate entrance, add more closet space, or even convert a third car garage into a full suite.

Once you've narrowed down your plan, you can ask a custom home builder for a building cost estimate - they'll be able to work with you to determine the specific costs for your area, including details specific to your lot or homesite.

Dan - My parents-in-law just went through the process.  My mother-in-law's mother is now living with them.  They chose a floor plan with the secondary bedrooms off a private hallway.  She uses one bedroom as her living room and the other as a bedroom, with a full bath inbetween.  The arrangement works well for them, and the resale value of the home is strong because it's still a fairly standard floor plan.   There are a lot of different options...

This is great info!  The in-law suites and casitas here provide much value to a home and it is rare to find one outside of the jumbo range!

Renee - There are plenty of options, but I think it takes just the right balance to match needs and potential resale value.

We don't count it as a suite unless it has a kitchen in it also.

Denise - the definition varies by area and by architect - which can make it very difficult for homebuyers to find a home or floor plan that has exactly what they're looking for.

Gordan - I would agree that it's hard to find in law suite plans!  We do a lot of work with our clients to modify existing home plans to meet their needs.  A local custom builder in your area experienced with modifications should be able to do the same thing for you.  Best of luck - if you're looking in the Triangle area, we'll be happy to discuss your needs further.

The rules are a little different here in the South. But still some great tips. As we all live longer this issue is not going away.
