★ The Process

How It Works

Three simple steps. We handle zoning, design, permits, and construction.

1

Tell Us About Your Lot

Address, lot size, and what you want — rental income, family suite, or both. Takes 3 minutes.

2

Free Zoning + Feasibility Report

We check your county's ADU rules, your setbacks, utilities, and which floor plans fit. Honest answer in 48 hours.

3

Pick a Plan, Lock Pricing

Choose Studio, 1BR, 1BR-over-garage, or standalone garage. Fixed-price contract. We handle permits + build.

★ The Plans

Four Detached ADU Options

All detached — no garage conversions, no attached additions. Built fresh from the slab up so your tenant has privacy and you keep full use of your main house.

Studio ADU — From $80k

Open layout, full kitchen + bath. Smallest footprint — fits the tightest setbacks. Great for short-term rental or single tenant.

1-Bedroom ADU

Separate bedroom + living area. Higher rent than studio, broader tenant pool (long-term renters, family members).

1-Bedroom Over Garage

Two-story unit: parking + storage on ground floor, full 1BR apartment above. Best ROI on smaller lots — you stack vertically.

Standalone Garage

Two- or three-car detached garage. Pre-wired and pre-plumbed for future ADU conversion if you want optionality.

Zoning + Permits Handled

Every Florida county treats ADUs differently. We know which counties allow what, run the feasibility for free, and pull every permit in-house.

Most ADUs Cash Flow in Year One

Typical Central FL ADU rents $1,400–$2,400/mo. On an $80K–$170K+ build, financed or paid cash, most owners break even on monthly debt service within months and earn from there.

★ The Numbers

How an ADU Pays for Itself

Real Central Florida numbers. Run the math on your own lot — we’ll send you a personalized estimate after the feasibility check.

Build Cost by Size

Fixed-Price Construction

$80K–$130K for 250–400 sqft (studio & compact 1BR). $130K–$170K for 400–600 sqft (full 1BR & 1BR-over-garage). $170K+ for 600+ sqft. Lump-sum contract — no surprises after you sign.

$80K–$170K+
Monthly Rent

Central FL Rental Comps

Studio ADUs in Seminole, Orange, and Volusia rent $1,200–$1,600/mo. 1BR units rent $1,500–$2,400/mo. Short-term (Airbnb) can run higher in tourist-adjacent counties.

$1,200–$2,400/mo
Payback

Most Owners Cash Flow Year One

Financed over 20 years at current HELOC rates, monthly debt service is typically below the rent. Pay cash and the ADU pays itself back in 4–7 years — then it’s pure cash flow plus appreciation on your lot.

4–7 yr cash payback

These are averages. Your real numbers depend on lot, plan, and county. We’ll send you a one-page ROI estimate specific to your address after the free feasibility report.

★ Common Questions

Frequently Asked Questions

Straight answers about the process, condition, and what we buy.

Is a detached ADU even allowed on my lot? ▾
It depends on your county, your specific zoning district, and your lot size + setbacks. That's exactly what our free feasibility check answers. Submit the form, we pull your parcel record and tell you yes/no in 48 hours.
How long does construction take? ▾
From contract signing: 8–12 weeks for permits + design, then 4–6 months for build. Studio units are fastest. Plan on 6–9 months total from "yes" to "tenant moves in."
What's included in the price? ▾
Permits, foundation, full construction, electrical + plumbing tie-in, HVAC, appliances, finishes. Site prep and utility extensions can vary — we quote those separately after the feasibility check.
Will the ADU have separate utilities? ▾
Standard build is sub-metered (one main meter, internal sub-meter for the ADU). Fully separate meters add cost but are doable. We talk through the tradeoffs based on whether you'll rent or use it for family.
How do I pay for it? ▾
Cash, HELOC, cash-out refi on your main home, or construction-to-perm loan. We can introduce you to lenders we've worked with who specifically finance ADUs. Most owners use a HELOC because the rate is favorable and the rental income covers the payment.
Can I use it for short-term rental (Airbnb)? ▾
Some counties allow it, some don't. We'll tell you what your county permits during the feasibility check. Where allowed, Airbnb usually nets 1.5–2x long-term rent but requires more management.
What if I just want a standalone garage, not a livable unit? ▾
We build those too. Two- or three-car detached garage, pre-wired and pre-plumbed so you can convert it to a livable ADU later without tearing into walls. Cheapest entry point and keeps your optionality open.
