Largo In-Law Suites When the Lot Is in a Flood Zone

In a Largo flood zone your parent's suite will share the family kitchen, so plan the rooms around shared meals rather than a kitchenette.

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.

Local Context

Why a Largo flood-zone suite shares the kitchen

Families often picture a suite with a small kitchen so a parent can make their own breakfast. On many Largo lots that picture has to change before anything is drawn. Largo's code, rewritten under Ordinance 2025-01, does not permit accessory dwelling units in the Special Flood Hazard Area or the Coastal High Hazard Area, and Florida defines an ADU by its separate kitchen, bathroom and sleeping area. Leave the kitchen out and the suite is a bedroom, bath and sitting room added to your home. Put one in and, on those lots, there is no category to build it under.

Deciding

Largo's rules if the lot is outside the flood zones

If the flood map puts the parcel outside both zones, a Largo suite with its own kitchen becomes possible as an attached ADU, with conditions to weigh before you choose it. It is capped at 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 the owner signs a notarized affidavit that the unit, if it is ever rented, will be rented only at an affordable rate as state law defines it, which binds the family's later options.

  1. Check both hazard areas

    Largo's ban covers both the Special Flood Hazard Area and the Coastal High Hazard Area, so check the parcel against each.

  2. Design the suite around shared meals

    Anything that looks like a second cooking area is a question for the city before it goes on the plan, not an assumption.

  3. Keep the tax budget realistic

    Largo homesteads sit outside the county's parent or grandparent reduction, so plan on the new space being assessed at just value.

Local Detail

Largo's 2025 ADU ordinance on flood hazard lots

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.

Florida Statute 163.31771 defines an accessory dwelling unit as an ancillary or secondary living unit that has a separate kitchen, bathroom and sleeping area, within the same structure or on the same lot as the primary dwelling.

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.

Under Florida's Save Our Homes statute, F.S. 193.155(4)(a), changes, additions or improvements to a homestead are assessed at just value as of the first January 1 after they are substantially completed.

Next Step

Is your Largo parcel in either hazard area?

Send the address. We check the flood zone first, because in Largo it decides whether the suite can have a kitchen at all.

Questions

Largo flood zone suite questions

How do I know if my Largo house is in the Special Flood Hazard Area?

It is on the FEMA flood map for the parcel. Send us the address and we check the flood zone, and the Coastal High Hazard Area, before any design is paid for.

Is a first-floor bedroom addition treated like an ADU in Largo?

Not when it has no kitchen of its own. Florida's definition of an ADU turns on a separate kitchen, bathroom and sleeping area, so a bedroom and bath joined to the house is an addition. On a flood zone lot it still faces the flood rules for additions.
