What Is a Mother-in-Law Suite?
A private living space right on your property.
A mother-in-law suite gives a family member their own bedroom, bathroom, living area, and private daily rhythm — while still keeping them close. It can be attached to your home, converted from an existing garage, or built as a detached guest house.
Evangelisto Construction designs each suite around your lot, your existing structure, local permitting, and how your family will actually use the space every day — the same care we bring to every home addition in Lakeland across Polk County.
We build in-law suites across Lakeland, Winter Haven, Bartow, Haines City, Davenport, and Polk City.
Choose the Right Build Type
Three ways to create private family space.
Every property is different. The right option depends on your existing home, lot size, budget, privacy needs, and future use.
Attached Addition
Expand the home with a connected suite that feels private but remains part of the main structure.
- Great for aging parents
- Can share existing utilities
- Strong long-term resale appeal
Garage Conversion
Turn underused garage space into a livable suite with bedroom, bath, comfort, privacy, and function.
- Lower build cost
- Uses existing roof and slab
- Ideal for compact layouts
Detached Guest House
Create a separate living structure for family, guests, future rental flexibility, or long-term independence.
- Best privacy
- Independent daily living
- Great for larger properties

Interactive Suite Cost Estimator
Get a realistic starting range before you call.
Use this planning tool to estimate the general range for a mother-in-law suite in Lakeland or Polk County. The final number depends on your property, foundation, plumbing, electrical, finish level, and permitting requirements. See all our construction services.
The first thing I look at is the existing structure — the slab, the walls, any foundation issues. Before we quote a price, we check what we're working with. Adding a bathroom always adds cost. The elevation of the property matters. And of course, size.

Age in Place Together
Keep aging parents close without removing their independence or privacy.
Rental Potential
A permitted suite may create future income potential depending on zoning and HOA restrictions.
Increase Home Value
Well-designed permitted living space can improve the usefulness and resale appeal of your home.
Adult Children
Create independent space for adult children while they save money or transition into their next chapter.
Guest Comfort
Give guests a dedicated place to stay without disrupting the main household.
Custom to Your Lot
Every design starts with your property, existing structure, setbacks, budget, and family needs.
Before You Build
The details that make or break an in-law suite.
The best in-law suite projects are planned carefully before construction starts. These are the items Evangelisto Construction reviews early so your project has a realistic path forward.
Zoning, Setbacks & HOA Rules
Before drawings are finalized, your property needs to be reviewed for local requirements and potential restrictions.
Foundation & Existing Structure
The slab, walls, roofline, and existing conditions affect both design and cost.
Bathroom, Plumbing & Utilities
A private bathroom is one of the biggest comfort upgrades and one of the biggest cost drivers.
Privacy & Daily Function
Entrances, sound control, storage, laundry, and accessibility should be planned before the first wall goes up.
