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.

Deciding

Sizing a Safety Harbor cottage once the lot passes

Once the lot qualifies, the size rules are the same as for an attached unit: at least 300 square feet, no more than 800, and no more than half the main home, with two occupants at most. Safety Harbor's NFIP record is short, 147 claims in all, though the parcel still needs a flood check. The building permit itself goes through Pinellas County Building and Development Review Services rather than a city building department, so the contractor files with the county.

  1. Check the district

    In E-1 a detached ADU is allowed without the corner or alley condition.

  2. Look at the lot's edges

    Outside E-1, only a corner lot or a lot with improved alley access may take a detached unit.

  3. Prove owner occupancy

    Safety Harbor reads it from the Pinellas homestead exemption on the property.

Local Context

Reading a Safety Harbor lot for a cottage

A separate cottage gives a parent their own front door, and in Safety Harbor whether you can build one depends on where the lot sits. In the E-1 district a detached ADU is allowed. Outside E-1, a detached unit is permitted only on a corner lot or a lot with improved alley access. Those are the three questions to answer from the survey and the zoning map before anyone designs a floor plan. If the answer to all three is no, the attached suite described on the Safety Harbor in-law page is the route that remains, and it is permitted in every single-family district.

Questions

Safety Harbor backyard cottage questions

What counts as improved alley access in Safety Harbor?

That is the city's call, and it is worth asking before a design is paid for. The code allows detached units outside E-1 only on corner lots or lots with improved alley access, so the answer decides the project.

Is there a minimum size for a Safety Harbor cottage?

Yes, 300 square feet, with a maximum of 800 and no more than half the main home. A very compact prefabricated unit may fall under the floor.
