Do you need a building permit in Atlantis, FL?

Atlantis requires building permits for construction, including new homes, additions and repair or replacement work.1 Atlantis also requires building permits for interior work involving electrical, plumbing or structural changes.11 The city has adopted the Florida Building Code, and the code includes floodplain construction requirements.12

An Atlantis owner-builder can act as the contractor for an eligible residence intended for the owner’s use or occupancy, with direct onsite supervision and the required affidavit and identification.8 The owner-builder exemption does not remove building permit or code-compliance obligations.13

Who issues building permits in Atlantis, and how do you apply?

The City of Atlantis Building Department is the building permit counter for Atlantis construction; use the department contact listed below for application and inspection questions.1 Applications need documentation showing the true value of the work, and exterior alterations require Architectural Review Committee approval.11 Exterior work on a home in a homeowners association must include written association approval.11

Atlantis collects building permit fees when the application is submitted; request a current written fee calculation from the Building Department before budgeting the project.11 Required Atlantis construction inspections must be called in by 3:30 p.m. for next-day scheduling; later calls are processed the following day.14

Does Atlantis have zoning, minimum lot sizes and setbacks?

Atlantis has city residential zoning standards, and the parcel’s district matters to the size of home you can build.5 In Atlantis R-1AAA, a single-family dwelling needs at least 3,000 square feet of ground-floor area; garages, porches, terraces, porticoes, patios and unenclosed carports do not count.5 The equivalent Atlantis ground-floor minimum is 2,000 square feet in R-1AA and 1,600 square feet in R-1A, with the same exclusions.72

Atlantis R-1AAA requires a minimum parcel area of 28,000 square feet and limits residences and accessory structures to 2 floors and 35 feet.615 Ask City Hall for the parcel’s district, setbacks and lot-coverage requirements before commissioning a site plan.16

How do septic permits and private wells work inside Atlantis?

Septic systems inside Atlantis are administered by the Florida Department of Health in Palm Beach County, rather than the city Building Department.3 For Atlantis construction using septic, health department plan approval must come before building permit issuance.4 Final approval of wells and septic systems must be recorded before a certificate of occupancy is issued.17

Private-well drillers in Palm Beach County submit location plans before drilling; drinking wells also need a satisfactory bacteriological report and completed wells are inspected.10 Confirm sewer availability before choosing septic: Florida requires a properly functioning septic system to connect within 365 days after written notice that qualifying sewer service is available, subject to statutory exceptions.18

Can you live in an RV, tiny home or manufactured home in Atlantis?

We could not confirm whether Atlantis allows residential RV occupancy or temporary camping on a private parcel; ask the Atlantis Building Department about the proposed use before buying a vehicle or arranging hookups.11 We could not confirm a separate Atlantis tiny-home occupancy rule; ask City Hall which district and dwelling standards would apply to the proposed structure.16

For a proposed single-family tiny home in Atlantis R-1A, the district’s 1,600-square-foot minimum ground-floor area is a substantial constraint.2 Atlantis generally does not permit manufactured homes, although the floodplain chapter describes requirements for any manufactured home that may be permitted; ask the city to resolve any proposed exception.9

What are the steps to building a home in Atlantis?

  1. Ask City Hall to identify the Atlantis parcel’s zoning district and confirm the applicable home-size and parcel standards before designing the house.165
  2. Ask the Atlantis Building Official about floodplain construction requirements for the site.1
  3. If the home will use septic, obtain health department plan approval before the Atlantis building permit; arrange private-well location review before drilling.410
  4. Submit the city building permit application with job-value documentation, architectural review and association approval where applicable, and the required fees.11
  5. Schedule required construction inspections, and ensure well and septic final approvals are recorded before requesting occupancy approval.1417

What should you check before buying land in Atlantis?

Start with the Atlantis district’s minimum home and parcel sizes, rather than assuming that a small footprint will fit the site.56 Ask the city Building Official about the planned construction and floodplain requirements before committing to the purchase.1 Atlantis driveway replacement needs a building permit; ask the Building Department separately about driveway-access approval for a new home.11

We could not confirm an Atlantis allowance for off-grid residential sanitation; take the proposed system to the city Building Department and the county health department.1119 For land outside Atlantis city limits, consult the Palm Beach County guide: the county’s general zoning framework applies to unincorporated land.20

Watch-outs

  • Ask Atlantis for a current building permit fee calculation when submitting the application.11
  • Atlantis exterior work can require architectural review even when a building permit is not required; ask the Building Department which application applies.11
  • Do not treat septic approval as a city building permit: Atlantis construction using septic needs health department plan approval before building permit issuance.4
  • Atlantis prohibits residential rentals shorter than 1 month in residential zoning districts.21
