About ADU Premium - Eco Tiny Houses

Eco-Friendly Tiny Homes and ADUs by ADU Premium

ADU Premium - Eco Tiny Houses designs and builds flexible living spaces intended to address the practical demands of modern urban life. Their focus is on eco-friendly, ADA-accessible accessory dwelling units (ADUs) and RVIA-certified tiny homes that can be placed in urban backyards or on residential properties. As an ADU builder and tiny home manufacturer, they offer a structured process from initial consultation through delivery and installation.

Their product lineup includes a range of ECO Tiny House models (THOW – Tiny House on Wheels) as well as permanent foundation ADUs. The models vary in size to suit different needs and site conditions:

  1. Model ECO 90 – 90 sq. ft + 28 sq. ft covered deck
  2. Model ECO 120 – 120 sq. ft + 28 sq. ft covered deck — priced at $49,200
  3. Model ECO 150 – 150 sq. ft + 28 sq. ft covered deck — priced at $61,500
  4. Model ECO 180 – 180 sq. ft + 28 sq. ft covered deck
  5. Model ECO 360 – 360 sq. ft + 28 sq. ft covered deck

Their ADU options include one-story units starting at 200 sq. ft and two-story units at 400 sq. ft, both with a covered deck and ADA-adaptable configurations. These units are built for permanent foundation installation and are suitable as granny flats, in-law suites, backyard cottages, or JADUs depending on local zoning requirements.

The ECO 120 model includes a full bathroom with shower, full kitchen with fridge and appliance connections, washer-dryer hook-up, on-demand water heater, combined A/C and heating unit, a twin or Murphy bed, built-in closet and storage, a safebox, and IKEA-compatible furniture. The unit is RVIA certified, and the purchase price covers permits, delivery within 50 miles, site installation, utility connection, and a certified title (DMV + MCO).

The ECO 150 model offers similar features but with a larger footprint and upgraded amenities, including a fully equipped kitchen, queen or king bed, and double built-in closet space. Like the ECO 120, it includes permits, delivery, installation, utility connection, and certified title in the listed price.

The ADU Process: From Site Visit to Delivery

ADU Premium follows a defined step-by-step process for clients. It begins with an initial consultation, which can take place in person at their factory, via a virtual Zoom tour, or by phone. After that, clients choose the ADU or tiny home model that fits their needs and space.

Following the model selection, ADU Premium conducts a free site evaluation. During this visit, their team assesses installation requirements, utility connections, site preparation needs, and permit considerations. This evaluation forms the basis for preparing the property for ADU installation.

For financing, ADU Premium has partnered with US Bank and offers several options. As RVIA-certified manufacturers, their clients may qualify for RV loans with terms ranging from 5 to 20 years at rates between 4% and 10%, with a down payment of 10–20%. Estimated monthly payments start around $300. Other financing options include HELOC, personal loans, tiny home lenders, and private lenders. Rental income potential from these units is estimated between $1,300 and $1,700 per month, with a projected return on investment of around 30% and a break-even point at approximately 33 months.

Units are typically ready for delivery within 90 days. ADU Premium states their structures are built using materials selected for fire resistance, insulation performance, and long-term durability.

Optional Add-Ons and Upgrades

Clients can also request a range of optional additions to their ADU or tiny home, including:

  1. Solar panels and energy storage systems
  2. EV charger installation
  3. Septic tank and water tank setup
  4. IKEA-compatible furniture and staging services
  5. Landscaping

ADU Premium - Eco Tiny Houses positions itself as a detached ADU builder and JADU contractor that handles much of the process end-to-end, including permits and utility connections. Their ADA-accessible designs and RVIA certification distinguish their offering within the accessory dwelling unit builder market.

"Terrible company when it comes to having them pay their transporter be aware when moving their tiny home very unprofessional. They cant be punctually causing you time and money when working with them and when you reasonably work out the situation they have and accommodate for a pay they will not hold there word and when continuing to ask about your payment Rodrigo will just say yes,yes eventually and then completely leaving you with no updates no calls and no payment this was very unprofessionally so be aware when doing work with ADU Premium you will not received payment."

"Terrible company to deal with, they pay to transport their trailers but then refuse to pay after the job is done and screws the transport company. Don't do business with them."

"Do not work with these people they will not pay or handle their end of the deal. Rodrigo will give you the run around and will stop replying eventually. We moved a tiny home for him he scheduled that's for a certain day.We showed up.That unit was not ready.He requested we wait and that he would cover the time lost. We stayed in our truck for a whe night to be ready for.him.in the morning and once it was done he went M.I.A"
