Understanding Orlando ADU Zoning & Setbacks: A Homeowner’s Guide
Thinking about building an ADU in Orlando? Here’s what every homeowner should know about zoning, setbacks, and the permitting process before you start your backyard project.
Why ADUs Are Growing in Orlando
Accessory Dwelling Units (ADUs), often known as granny flats, in-law suites, or backyard cottages, have become a rising trend in Orlando. With population growth, rising home prices, and a strong rental market, Central Florida homeowners are exploring ADUs as a smart way to:
Add living space for family or guests
Create passive rental income
Boost property value without buying a new home
The City of Orlando and Orange County have taken steps to make ADUs more accessible, especially in residential neighborhoods. But before you break ground, it’s essential to understand local zoning and setback rules, which determine what’s allowed on your property.
What Is an ADU in Orlando?
An ADU is a secondary residential structure built on the same lot as a primary home. It can be attached (like a converted garage or basement) or detached (like a small standalone unit in the backyard).
In Orlando, ADUs are typically permitted as accessory uses in single-family residential zones — but the exact rules depend on:
Your property’s zoning designation
Lot size and shape
Setback distances from property lines
Building height and lot coverage limits
Utility connections and parking availability
Good news: Orlando has been a statewide leader in allowing ADUs in more neighborhoods, making it one of the most ADU-friendly cities in Florida.
Zoning Basics for ADUs in Orlando
Your property’s zoning district determines if and how you can build an ADU. Orlando has several residential zoning categories, such as:
R-1 (Single-Family Residential)
R-2 (Low-Density Residential)
R-3 / R-3B (Medium-Density Residential)
Many R-1 and R-2 zones allow one ADU per lot, provided it meets setback, size, and design standards. Generally:
The ADU must remain smaller than the primary residence
It cannot be sold separately from the main home
The property owner must usually live on-site in either the main house or the ADU
Tip: You can find your zoning designation using City of Orlando’s Zoning Map
Typical Setback Rules for ADUs in Orlando
Setbacks are required distances between structures and property lines. Orlando’s rules are similar to many Florida municipalities but have a few local nuances.
Typical Orlando ADU setback guidelines:
Rear yard: Minimum 5 feet
Side yards: Minimum 5 feet
Front yard: ADUs are typically not allowed in front yards
Separation from main house: Usually at least 10 feet for detached units
These rules help maintain neighborhood character, provide access for emergency services, and ensure privacy between properties.
Important: If your property is in a historic district or a Planned Development (PD), there may be additional design or placement restrictions.
Orlando ADU Permitting & Approval Process
The City of Orlando has a well-defined process for reviewing and approving ADU projects. While it might seem daunting at first, understanding the steps will help keep your project on schedule:
Confirm Zoning Eligibility
Check that your zoning district allows ADUs and that your lot meets minimum size requirements.Preliminary Design & Site Plan
Work with a designer or modular ADU builder to create a layout that fits setback and lot coverage rules.Permit Application
Submit your plans through the City of Orlando Permitting Portal. This includes structural, electrical, plumbing, and other relevant permits.City Review & Revisions
City staff will review your application for compliance with zoning, building, and utility codes. Minor revisions are often required.Inspections During Construction
As the ADU is built, inspections ensure it meets Florida Building Code and local standards.
Working with a builder experienced in Orlando permitting can significantly reduce delays and simplify communication with city departments.
Central Florida Building Considerations
Orlando’s inland location means wind speeds aren’t quite as extreme as coastal Miami, but hurricane resilience is still required. Modular ADUs built to Florida code must meet:
Wind load requirements for the region
Proper anchoring systems for detached units
Flood elevation standards if in a flood zone
Mesocore’s modular ADUs are pre-engineered to meet Florida’s building and wind codes, helping homeowners navigate the permitting process with confidence.

Frequently Asked Questions (FAQ)
Can I build an ADU on any residential property in Orlando?
Most single-family lots can support one ADU, but zoning, lot size, and special overlays (like historic districts) may affect eligibility.
How large can my ADU be in Orlando?
Generally, ADUs must be smaller than the primary home and cannot exceed certain square footage depending on lot size. Many fall between 600–800 sq. ft.
Do I need to provide extra parking?
Parking requirements vary by zoning district. Some neighborhoods near transit corridors may have reduced or waived parking requirements for ADUs.
Can I rent out my ADU?
Yes — Orlando allows long-term rentals of ADUs, but short-term rentals (under 30 days) may have additional rules. Always check city regulations before listing.
