The average cost to build an ADU in Florida depends on size, layout, and finishes. At Goshen Tiny Homes, our ADUs are block-built on slab foundations and priced with full transparency. Here’s what our clients typically invest:

These are our actual pricing ranges, not broad industry averages. Costs vary based on square footage, finishes, and design choices — for example, a larger ADU with upgraded kitchens or baths will fall at the higher end.

Some builders advertise low “base prices” but leave out essentials like utility hookups or permits. Goshen’s pricing is true turnkey, so you know exactly what’s included from day one.

At Goshen Tiny Homes, the average time to build an ADU in Florida is about 8–12 months from start to finish. Because we specialize only in ADUs, our process makes your ADU project timeline more predictable:

• Design & architecture: about 2 months
• Permitting & approvals: 2–6 months (permitting timelines for ADUs vary by jurisdiction)
• Construction: 3–5 months, depending on ADU size and finishes

Smaller ADUs or tiny homes may finish sooner, while larger or more complex builds — like a two-bedroom ADU — can take longer.

Knowing your ADU construction schedule upfront helps you plan financing, rental income, and family needs with confidence. Most of our clients are surprised at how smooth the process feels once Goshen manages zoning, permitting, and inspections for them.

At Goshen Tiny Homes, our ADU pricing in Florida is truly turnkey — covering everything you need for a complete, move-in-ready Accessory Dwelling Unit (ADU). Unlike some builders who advertise a low “base price” and then add extras, we show you the full picture upfront.

• Design and engineering plans
• Architecture and permits
• Full construction: concrete foundation, block walls, roofing, electrical, plumbing, HVAC
• Complete finishes: full bathroom, full kitchen, flooring, interior finishes, all appliances

• Final inspections and certificate of occupancy

At Goshen Tiny Homes, every ADU is 100% site-built using traditional construction code — never prefabricated kits. Our ADUs are block-built on slab foundations, inspected at every stage, and fully permitted to Florida Building Code Section 110.3 standards, ensuring compliance.

This difference matters:

• Site-built ADUs qualify as real property. They appraise like a home and add long-term equity.
• Prefab ADUs in Florida often face zoning restrictions. Many counties don’t allow them, and even when they’re installed, they usually don’t count as real estate.
• Prefab tiny homes can cost $100,000+ but still fail zoning approval, leaving homeowners with assets that don’t add value.

Whether you call it a tiny home, modular ADU, or backyard cottage, building on-site ensures your unit is compliant, insurable, and a true real estate investment.

Yes — you can build an ADU, tiny house on a property with a septic system in Florida, but the Health Department must approve septic capacity before permits are issued. In most cases, you’ll have three options:

• Connect to the existing septic system (if it has enough capacity).
• Upgrade the existing septic system — usually $2,000–$5,000, sometimes up to $7,000 depending on complexity.
• Install a new septic system — typically $7,000–$10,000, and in some cases up to $15,000 depending on size and soil conditions.

Most homeowners don’t realize septic capacity rules can delay or stop an ADU project. That’s why at Goshen Tiny Homes, we coordinate a full ADU septic evaluation report with licensed contractors and the Health Department before you sign a contract. This way, you’ll know the real cost and required option upfront — with no surprises later.

Yes — a block-built Accessory Dwelling Unit (ADU), sometimes called a tiny house, almost always increases property value in Florida. Because it’s built to the Florida Building Code and appraises like a new construction home, an ADU is treated as real estate — not a temporary structure.

Here’s why ADUs boost value and deliver strong ROI:

• Equity boost: Adds livable square footage that often appraises higher per square foot than the main home. 
• Rental income potential: An ADU can generate steady cash flow, often covering most or all of your mortgage. 
• Buyer demand: Buyers (especially families and investors) pay a premium for homes with secondary units. 
• Resale value: ADUs are considered a high-demand feature in Florida, increasing your property’s resale appeal. 

ADU ROI Example:

💡 For comparison: According to 2025 Florida real estate data, a typical single-family home in Florida (valued at $380,000, renting at $2,466/month) yields only a 7–8% ROI. That means an ADU investment can nearly double your return.

Yes — in most parts of Florida, you can legally rent out an ADU or tiny house, as long as it’s built to the Florida Building Code and properly permitted. Because Goshen ADUs are block-built, slab-on-grade, and fully permitted, they qualify as legal rental units that appraise like real estate.

Here’s what to know about ADU rental laws in Florida:

• Long-term rentals (6+ months): Generally allowed across Florida if the ADU meets zoning and building standards.
• Zoning requirements: Rules differ by city and county, so exact rental allowances can vary.
• Owner occupancy: Some municipalities may require the property owner to live on-site if renting an ADU.
• Rental income potential: Many Florida homeowners legally rent their ADUs to offset or even cover their mortgage.

The size of an Accessory Dwelling Unit (ADU) in Florida depends on local zoning rules and the size of your main house. While each city and county is different, here are common ADU square footage limits in Florida:

• Typical range: Most ADUs fall between 400–800 sq. ft.
• Maximum size: Often between 650–1,000 sq. ft., or up to 80% of the main home’s size.
• Minimum size: To qualify as a legal dwelling, most counties require at least 200 sq. ft.

Most homeowners want to maximize square footage — and at Goshen Tiny Homes, we make sure your design gets every inch the code allows. We confirm exact zoning standards upfront so you know what’s possible before design or permitting.

ADU rules and zoning requirements in Florida vary widely by city and county, which is why zoning is often the #1 pain point for homeowners. What’s allowed on one property may be restricted just a few blocks away.

Here are some of the most common Florida ADU zoning requirements:

• Size limits: Typically 400–800 sq. ft., with maximums from 650–1,000 sq. ft. or up to 80% of the main home’s size.
• Setbacks: Rear setbacks are usually 5–20 feet; side setbacks are often 5–10 feet.
• Owner occupancy: Certain cities require the homeowner to live on-site if renting the ADU.
• Utilities & septic: If your property is on septic, the Health Department must approve capacity before permits are issued.

At Goshen Tiny Homes, we know ADU zoning in Florida is confusing and constantly changing. That’s why we research every property, confirm with local departments, and give you clarity before moving into a contract. With us, you’ll know exactly what’s possible before spending a dollar on design or construction.
