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?

Where is the property?

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

Local Context

Why New Port Richey reads the estimate so closely

A bedroom and bath on the ground floor lets someone stop climbing stairs without leaving the house. In New Port Richey, the paperwork behind that suite carries more weight than usual. The city applies the 50 percent substantial improvement test against the Property Appraiser's assessed structure value, or a licensed appraisal, and it requires a cost estimate signed by a licensed contractor with an affidavit that the estimate includes all improvements. That means the quote is not only a price for you; it is the number the city tests. Every item, from the new bath to updates in the old rooms, belongs on it.

Deciding

Structure value and flood exposure in New Port Richey

Half the homes in New Port Richey were built before 1980, and the city's NFIP record holds 1,232 claims, 450 of them in 2024. On an older house, check the assessed structure value before the design is set, and consider the licensed appraisal the city accepts if that figure looks low. Crossing the 50 percent line brings the whole house under current flood rules, which is a different and larger project than a suite.

  1. Ask for a complete estimate

    The city wants every improvement on it, signed by a licensed contractor and backed by an affidavit.

  2. Check the assessed structure value

    That is the figure the 50 percent test is measured against unless a licensed appraisal is provided.

  3. Know the stakes

    At 50 percent of the structure's market value an addition is a substantial improvement, and the existing house has to meet current flood rules too.

Questions

New Port Richey downstairs suite questions

Why does New Port Richey want an affidavit with the estimate?

Its substantial improvement packet asks for a cost estimate signed by a licensed contractor, with an affidavit that it includes all improvements, so the 50 percent test is run against the whole job. A partial estimate would understate it.

Can a first-floor suite in New Port Richey have its own kitchen?

Only as the city's accessory apartment, which must sit inside the principal structure and use no more than 25 percent of the home's gross floor area. A suite for your own use can share the main kitchen.
