Container Guest Houses

A real guest house, finished to match your home.

Custom-built container guest houses and in-law suites for Florida living. Faster than traditional construction, finished with real siding, HVAC, plumbing, and electrical so it looks like a cottage, not a shipping container.

Licensed and Insured

Every container build is performed by licensed Florida contractors with full insurance coverage.

40+ Years Experience

Four decades of Southwest Florida project work across residential, commercial, and multi-family properties.

Financing Available

Container builds can be financed through Hearth or traditional construction financing. Ask us for options.

The cost story

Faster timeline. More predictable budget.

Traditional additions in Southwest Florida run $250 to $400 per square foot, take 6 to 12 months, and require full permitting with every trade coordinated separately. Container guest houses come in below that range for most configurations and are delivered in 12 to 20 weeks, not 12 to 18 months. We quote a fixed scope so you know the full number before we start. Contact us for current project pricing based on your specific site and finish goals.

Permitting and code

We handle the permit process

Container guest houses are habitable structures under Florida Building Code, which means they require a permit in every SW Florida county. We manage the full process, including structural engineering drawings, county submission, inspection scheduling, and final certificate of occupancy. Most counties in our service area (Sarasota, Lee, Manatee, Charlotte, Collier, and Hillsborough) have a well-established path for this type of build. Permit timelines vary; we factor them into your project schedule from day one.

Use cases

Who builds container guest houses

In-law suite

Keep family close without living on top of each other. A finished guest house gives aging parents or adult children their own entrance, kitchen, and bathroom.

Guest cottage for snowbird season

Out-of-state family visits for weeks at a time. A dedicated guest house means everyone is comfortable and no one is sleeping on the pull-out.

Airbnb and short-term rental income

A finished container guest house on your property qualifies as a separate dwelling and can generate rental income on Airbnb or VRBO year-round.

Home office with separation

Work-from-home professionals who need a real boundary between work and home. Walk out your back door into a proper office.

Vacation cabin on a rural lot

Off-grid placement with RV hookups, solar, and a propane system. A full-season cabin at a fraction of traditional build cost.

Property value addition

Adding a habitable structure to your lot adds appraised value. Many clients use the rental income to offset or fully cover the build cost over time.

How it works

From concept to move-in

  1. 1

    Design consultation

    We review your site, goals, and budget. You leave with a clear configuration recommendation, a preliminary scope, and a realistic timeline.

  2. 2

    Site prep

    Pad or foundation installation, utility connections, and permit submission. We coordinate all trades. You get a single point of contact.

  3. 3

    Container build-out

    Containers can be partially built in our facility before delivery, which reduces on-site time and weather exposure. Interior framing, insulation, rough plumbing, and electrical all happen before the crane shows up.

  4. 4

    Delivery and placement

    Crane offload and precise positioning on the prepared pad. Most placements take a few hours once the crane is on-site.

  5. 5

    Finish work

    Siding, roofing, windows, doors, interior finishes, HVAC hookup, plumbing fixtures, and final electrical. This is where the container stops looking like a container.

  6. 6

    Inspection and move-in

    Final county inspection, certificate of occupancy, and your walkthrough. We do not consider a job done until everything is right.

Common questions

Container Guest Houses FAQ

Only if you want it to. With Hardie board siding, stucco, a real roof line, and trim matched to your home, most finished guest houses are indistinguishable from a stick-built cottage. We show you photos before we start.
A fully finished guest house typically runs 12 to 20 weeks from contract to move-in, depending on finish level and permit timelines. Studio configurations are faster; multi-container builds take longer.
Yes. Container builds qualify for Hearth financing and some construction loan products. We can walk you through options when you request your quote.
Yes. We manage the full permit process for every habitable container build, including engineering, county submission, and inspections. We know the process for Sarasota, Lee, Manatee, Charlotte, Collier, and Hillsborough counties.
Yes. Containers are inherently mobile. Moving one requires plumbing and electrical disconnects, a crane or tilt-bed truck, and re-installation at the new site. We handle all of it.
Habitable containers generally add to property value similarly to a traditional addition. Insurance treatment varies by carrier. We recommend a conversation with your insurer before you start.
