Thinking of the garage in New Port Richey?
If its floor is below base flood elevation, a bath cannot go there without raising it. Send the address and we will look at the elevation question first.
New Port Richey's internal apartment rule and base flood elevation
A breezeway or roofed passage does not turn a separate building into part of the house, so the apartment really does sit inside the home's walls. Flood is the second rule. The city applies the 50 percent substantial improvement test against the Property Appraiser's assessed structure value or a licensed appraisal, and it wants a cost estimate signed by a licensed contractor, with an affidavit that it covers all improvements, before it issues the permit. Below the base flood elevation only parking, building access and limited storage are allowed, and bathrooms, laundry and mechanical equipment must sit at or above it, so a low garage cannot simply become a bedroom and bath. Half the city's homes predate 1980, and its NFIP record holds 1,232 claims. Pasco County's parent or grandparent reduction is available for a finished suite, with the final building permit in hand at application.
