Building permits in Sebastian

Who issues building permits in Sebastian?
Building Department issues permits for property inside Sebastian, Indian River County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Sebastian?
Often yes. Florida's owner-builder provision (Florida Statutes 489.103) lets an owner permit and perform work on their own home under specific conditions, including that the home is not offered for sale or lease within a year. The owner takes on the responsibilities a licensed contractor would carry. Sebastian may require you to sign an owner-builder disclosure.
Does the Florida $7,500 permit exemption (HB 803) apply in Sebastian?
From July 1, 2026, HB 803 exempts cosmetic work on a single-family home valued under $7,500 from needing a building permit statewide, so it applies in Sebastian too. It does not cover electrical, plumbing, structural, mechanical, or gas work, or property in a flood-hazard area, and you must still file a written exemption request and meet the building code.
How much does a permit cost and how long does it take in Sebastian?
Fees and review times are set locally and change often, so confirm the current numbers with Building Department or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
