Largo Parent Suites, Planned From the Flood Map Out

Check the flood map for your Largo parcel first, because here it decides whether a separate unit is allowed at all. Largo does not permit ADUs in the Special Flood Hazard Area or the Coastal High Hazard Area, so on those lots an attached suite without a second kitchen is the way to house a parent.

Five short questions about who the space is for and what it needs to hold, then where to reach you. Most people finish in about a minute.

Question 1What are you thinking of building?

Pick the closest. If you are not sure yet, that is exactly what we help sort out.

Question 2Who will live in it?

This matters more than it sounds. In Florida the answer can change the property tax on what you build.

Question 3Does the new space need its own kitchen?

In Florida law a space with its own kitchen, bathroom and bedroom is a second dwelling, and each city and county decides whether one is allowed on your lot.

Question 4Is the house in a flood zone?

In a flood zone, a large enough addition can mean the whole house has to meet today's flood rules. Your insurance declarations page or the county flood map will say.

Question 5When does the space need to be ready?
About you, and the house the space would join

Who should we ask for?

How can we reach you?

We call to confirm the details before anyone is sent out.

Where is the property?

The contractor match is by property, not by person, so the street line matters.

Largo's 2025 ADU code and garage conversion standards

A wide doorway with no threshold and a lever door handle

Largo's Comprehensive Development Code (Sec. 16.14, Ord. 2025-01) does not permit ADUs in the Coastal High Hazard Area or the Special Flood Hazard Area, caps an ADU at 800 square feet or 50 percent of the principal home's living area, whichever is less, requires either the main home or the ADU to be owner-occupied, and requires a notarized affidavit that the unit, if rented, will be rented only at an affordable rate as defined in F.S. 163.31771.

Largo's garage conversion standards require a replacement on-site parking space if the garage was the only one, architectural consistency with the home, and compliance with the ADU section if any part of the enclosed garage is used as an accessory dwelling unit.

The 2020-2024 American Community Survey estimates Largo's median age at 49.3, with 28.0 percent of residents aged 65 or older and 32.4 percent aged 62 or older, compared with 26.4 percent aged 65 or older in Pinellas County. Of its 46,806 housing units, 56.5 percent were built before 1980 and 13.0 percent in 2000 or later.

Because the Pinellas County parent or grandparent reduction requires the property to be in unincorporated Pinellas County, homesteads inside St. Petersburg, Clearwater, Largo, Pinellas Park, Dunedin, Seminole, Safety Harbor, Tarpon Springs and Oldsmar do not qualify under the county program as the Property Appraiser describes it.

Largo's ADU ban in flood zones and what it leaves open

Largo rewrote its ADU rules in 2025 and they are specific. Outside the flood zones an ADU may be up to 800 square feet or half the main home's living area, whichever is less; either the house or the unit must be owner-occupied; and a notarized affidavit commits any future rental to an affordable rate as state law defines it. Garage conversions have their own conditions. If the garage was the only parking, a replacement space has to be planned, the finished work has to match the house, and a kitchen anywhere in the enclosed garage brings in the ADU limits. The median age in Largo is 49.3, and 497 of the city's 781 NFIP claims came in 2024. Largo homesteads sit outside the county's parent or grandparent tax reduction.

What can be arranged on a Largo lot, flood zone or not

In-Law Suite Additions

Add a bedroom, a bathroom and a sitting room onto the house so a parent can live with you and still close a door of their own, planned so the kitchen decision does not turn it into a second dwelling by accident.

First-Floor Primary Suite Additions

Put a bedroom and a bathroom on the ground floor for someone who can no longer manage the stairs, without the addition pulling the whole house under current flood rules.

First-Floor Suites in Largo →

Detached ADUs and Backyard Cottages

Put a small, separate home in the backyard for a parent, close enough to help and far enough for their own front door, under the rules that actually govern the lot.

Garage Conversions to In-Law Suites

Turn the garage into a bedroom and bath for a parent, using space the house already has, without finding out afterward that the slab sits too low to be living space.
