Owner-Builder Permits in Miami-Dade County – What You Need to Know 2026

Owner-Builder Permits in Miami-Dade County

Miami-Dade County allows property owners to apply for building permits as owner-builders — performing construction work on their own property without hiring a licensed general contractor. The Owner-Builder permit is specifically authorized under Florida Statute 489.103 and Miami-Dade County Code Chapter 8. However, this option comes with substantial legal obligations, personal liability, and restrictions that many property owners do not fully understand before applying. Miami-Dade County's RER (Department of Regulatory and Economic Resources) publishes specific Owner-Builder Instructions that must be reviewed in full before applying. The Miami-Dade Building Department provides the Building Permit Application with an Owner-Builder Declaration section that the owner must sign under penalty of law.

Legal Requirements for Owner-Builder Status

To legally apply as an owner-builder in Miami-Dade County and throughout Florida, the property owner must meet several criteria. The property must be the owner's primary residence — a building that the owner intends to occupy as their personal home. Commercial properties, rental properties, and speculative construction (building to sell) are generally not eligible for owner-builder permits. The owner must personally supervise and perform the work — they cannot hire a general contractor to perform the work under the owner-builder permit. Subcontractors (licensed electrical, plumbing, and mechanical contractors) may perform the specialty trade work under the owner-builder permit, but they must obtain their own sub-permits. Under Florida Statute 489.103(7), an owner using an owner-builder permit may not sell the property within one year of completion of the work without disclosing to the buyer that the work was done under an owner-builder permit and without the supervision of a licensed contractor.

Owner Responsibilities Under the Owner-Builder Program

The owner-builder assumes all responsibilities that would otherwise fall to a licensed general contractor. This includes ensuring that all work complies with the Florida Building Code and applicable local codes, coordinating all trades and subcontractors, obtaining all required inspections, maintaining the permit card on site, ensuring the property address is posted and visible from the street during construction, and keeping all permits current and valid. If the owner cannot attend to the project personally — due to travel, illness, or other commitments — no one else can supervise the work unless they hold a valid contractor license. The owner-builder also assumes all personal liability for the construction quality, safety of workers on the site, and compliance with all applicable laws.

Required Documents for Owner-Builder Permit Application

Applying for an owner-builder permit in Miami-Dade County requires a completed Building Permit Application with the owner-builder declaration section fully executed, proof of property ownership (typically a copy of the recorded deed or property tax records), a valid government-issued photo ID, construction plans meeting all plan review requirements (same as for a licensed contractor permit — no reduced plan requirements for owner-builders), USD permit fees per the Building Fee Schedule, and a Plumbing and Gas Fee Sheet or Electrical Fee Sheet if those trades are included in the scope.

Plan Review for Owner-Builder Projects

Owner-builder projects undergo the same rigorous plan review as contractor-permitted projects. Miami-Dade County's Building Division plan reviewers review the submitted construction documents for compliance with the Florida Building Code without any reduction in requirements because the applicant is an owner rather than a contractor. For structural work requiring a licensed structural engineer of record, the engineer's signed and sealed plans and calculations are still required. For electrical, mechanical, and plumbing work, the same code requirements apply. The plan review timeline of 5 to 30 days for small residential projects applies to owner-builder applications just as it does to contractor applications.

Trade Subcontractors Under Owner-Builder Permits

While the owner-builder may perform general construction work — framing, masonry, concrete, site work — licensed subcontractors must perform all licensed trade work. Electrical work in Miami-Dade County requires a licensed electrical contractor holding a valid EC license from Florida DBPR and a valid Miami-Dade County Local Business Tax Receipt. Plumbing and gas work requires a licensed plumbing contractor. HVAC and mechanical work requires a licensed mechanical contractor or HVAC contractor. These subcontractors obtain sub-permits under the owner-builder's master permit. The subcontractors bring their own insurance and are responsible for their specific scopes of work. The owner-builder must ensure that sub-permits are properly obtained before the subcontractor begins work.

The One-Year Resale Restriction

One of the most important restrictions on owner-builder permits is the one-year resale restriction under Florida law. If an owner uses an owner-builder permit to construct or substantially renovate a property, they may not sell that property within one year of obtaining the final certificate of occupancy or certificate of completion without disclosing to the buyer in writing that the work was performed under an owner-builder permit and without a licensed contractor overseeing the work. This disclosure requirement exists because owner-built construction may not have the same quality assurance that comes with a licensed contractor's oversight and warranty. Many buyers and their lenders are reluctant to purchase owner-built properties, and failure to make the required disclosure can expose the seller to legal liability for construction defects discovered after the sale.

Inspections and Government Inspector Accountability

Owner-builder projects require all the same mandatory inspections as contractor-permitted projects. The property owner must request inspections, ensure that the work is ready for inspection, and be available to meet with the building inspector. In Miami-Dade County, inspections are performed Monday through Friday from 8:00 a.m. to 3:30 p.m. The permit card must be posted on-site and the approved plans must be available for the inspector's review. Failed inspections require correction of the deficiency and scheduling of a reinspection with a USD reinspection fee. Owner-builders who are experiencing difficulties with government inspector errors — inspectors who fail to appear, who cite incorrect code sections, or who impose requirements beyond what the code mandates — may find themselves at a disadvantage compared to a licensed contractor who deals with government inspectors regularly. Endless Life Design advises clients who are considering owner-builder permits to carefully evaluate whether the complexity of their project exceeds the practical capabilities of an owner-builder and whether professional project management would better serve their interests.

Risks and Limitations of the Owner-Builder Option

The owner-builder option can be appropriate for small, straightforward projects on a property owner's primary residence when the owner has genuine construction knowledge and skills. However, it is inappropriate for complex projects — major structural additions, complete home renovations, pool construction, or any project requiring extensive coordination of multiple licensed trades. The risks of the owner-builder approach include personal liability for construction defects, difficulty obtaining homeowner's insurance while construction is underway (some insurers exclude owner-builder projects), the one-year resale restriction, and the loss of contractor warranty protection. If the project exceeds the owner's management capacity and the owner needs to hire someone to oversee the work, that person must hold a valid contractor license — an owner cannot pay an unlicensed individual to supervise or perform construction under an owner-builder permit.

USD Costs for Owner-Builder Permits

Owner-builder permit fees in Miami-Dade County are the same as for licensed contractor permits — the USD fee schedule does not differentiate. The owner saves the general contractor's overhead and profit (typically 15% to 25% of total project cost) but assumes all the responsibilities and risks that the contractor would otherwise bear. For large or complex projects, the general contractor's oversight, warranty, and project management expertise often represent genuine value that exceeds their markup. Property owners should calculate the total USD cost — including the value of their own time, the risk of mistakes that must be corrected at additional USD cost, and the potential impact on resale value and insurance — before deciding whether the owner-builder option is truly the most economical choice.

Amnesty and Code Relief for Owner-Built Structures

Some older residential properties in South Florida have portions that were built by a previous owner under a self-help or owner-builder approach without proper permits or with permits that lacked mandatory inspections. These unpermitted structures — whether room additions, garage conversions, or accessory buildings — are eligible for the Miami-Dade County Code Relief (Amnesty) program under Ordinance 02-44. The Code Relief program allows a remedial permit and inspection process to bring these structures into compliance with the current building code. USD fees apply and structural upgrades may be required if the existing construction does not meet current Florida Building Code requirements. The Code Relief program is the legitimate pathway to resolving unpermitted construction — not something to ignore or hide during a property sale.
