The Backyard Opportunity
Unused Land Can Become a Smarter Living System
Most homeowners have land sitting unused behind the house. That space could become rental income, family housing, a guest suite, a home office, a downsizing option, or the first layer of a more sustainable Florida living system. We help make the path practical: zoning, feasibility, design, permitting, and build coordination.

What We Build
What Is an ADU?
An ADU — Accessory Dwelling Unit — is a legal second home built on your existing residential property. Think of it as a fully independent living unit: its own entrance, kitchen, bathroom, and everything a renter needs to call it home.
Every ADU we build is a permanent, foundation-built structure that goes through the full county permitting process. No shortcuts. No gray areas.
What We Build
- Foundation-built permanent structure
- Fully permitted by the county
- Florida Building Code compliant
- Custom-designed for your lot
- Site-evaluated and zoning verified
What We Don't Do
- Tiny homes on wheels
- RV-style or temporary units
- Non-permitted structures
- One-size-fits-all solutions
Every property is different. Before any work begins, we conduct a full site evaluation covering zoning, setbacks, utility access, and feasibility — at no cost to you.

What Orange County Requires
Official Permitting Requirements
We follow every Orange County regulation exactly. Here's what the county requires for each ADU type, sourced directly from orangecountyfl.net.
Orange County Eligibility Requirements — Know Before You Build
Before any building permit can be issued, Orange County requires ADU projects to meet the following baseline eligibility standards. EarthNest Florida verifies all of these during your free site evaluation.
Owner-Occupancy / Homestead Requirement
Orange County (unincorporated) requires the primary single-family dwelling and the ADU to remain under single ownership at all times. The owner must occupy either the primary home or the ADU as their principal residence, with homestead alignment consistent with county review. A Certificate of Occupancy will not be issued until homestead status is confirmed.
Special Exception Approval
In most Orange County residential and agricultural zoning districts, an ADU requires approval as a Special Exception — a separate zoning review process — before a building permit can be applied for. EarthNest Florida coordinates this step as part of your project process.
ADU Size Limits
- Minimum: 400 sq ft of living area
- Maximum: 50% of the primary home's living area OR 1,000 sq ft — whichever is less
- Exception: Lots 2 acres or larger allow up to 1,500 sq ft
- Maximum: 2 bedrooms
Lot Size Requirement
A detached ADU may only be built on a lot that is at least 1.5x the minimum lot area required for a single-family dwelling in that zoning district.
Setbacks — Detached ADU
- 1-story: Minimum 5 ft from rear property line
- 2-story: Minimum 15 ft from rear property line
- Minimum 10 ft separation between the ADU and primary dwelling
- Side setbacks: Must meet principal structure minimums for the zoning district
Short-Term Rental Restriction
Orange County prohibits short-term rentals (under 30 days) in most residential zones. ADUs may only be rented under standard long-term residential leases. Short-term rental platforms (Airbnb, VRBO, etc.) are not a permitted income strategy for ADUs in Orange County (unincorporated).
Note: Requirements vary by municipality. The City of Orlando, Osceola County, Seminole County, and Lake County each operate under their own ADU rules. EarthNest Florida reviews the specific requirements for your parcel as part of the free evaluation.

Our Process
From Concept to Keys — 7 Steps
Every project follows the same structured approach. You always know where you are in the process and what comes next.
Start Step 1 — Free Evaluation01
Property Evaluation
We visit your property and assess lot size, access, drainage, utility hookups, and overall build viability — free of charge.
02
Zoning & Feasibility
We review your property's zoning classification, confirm homestead eligibility, verify the special exception approval requirement, check setbacks and lot size minimums, confirm ADU size limits based on your primary home's square footage, and verify HOA restrictions if applicable — before any design work begins.
03
Special Exception Filing
For most Orange County residential properties, we prepare and submit the Special Exception application to Orange County's Planning Division on your behalf. This is the required zoning approval step before a building permit can be applied for. We manage the timeline and follow-up so you don't have to.
04
Design
You choose your layout and style. We work with our design team to produce engineered plans tailored to your property and preferences.
05
Permitting
We submit all required documents to Orange County and manage the full permit process. No surprises. No shortcuts.
06
Build
Our vetted construction team builds your ADU to Florida Building Code standards with quality materials and clear timelines.
07
Rent or Sell
Once your ADU passes final inspection, you're ready to rent it out — or use it to increase your property's market value.
