Off-Grid Tiny Homes

Off-grid ready means a home built to accept its own power, water and waste systems rather than municipal hookups. KYRAX builds off-grid ready homes in three formats: a modular home on a foundation, a park model, and a home on wheels. Which format you choose decides where you can legally place it, so the format question comes before the systems question.

An off-grid home runs its own power, water and waste instead of connecting to municipal services. KYRAX off-grid builds are specified before construction starts, so the solar array, battery storage, water collection and toilet choice are sized for your site and your actual loads rather than fitted to a standard package. You can stage the work: specify the capacity now and install the full array later.

02 — What to know

Sizing solar for winter, not for an annual average

A solar array sized on an annual average will underperform in December, when sun hours are at their lowest and heating and lighting loads are at their highest. Sizing that holds up year round starts from the winter figure for your specific site and the loads you actually run, not from a headline wattage.

That is why the array, the battery bank and any backup source are specified together at design time rather than picked off a package list. Two homes of the same size on different sites do not need the same system.

Off-grid in a cold climate is mostly an envelope problem

Every watt the building loses is a watt the array has to replace in the season it produces least. Insulation, air sealing and window specification do more for off-grid viability in a Canadian winter than adding panels does. Water lines and tanks also need freeze protection that does not depend on grid power, and a backup heat source has to work when the batteries are low.

KYRAX builds for Canadian winters as standard. Engineered R-values for the envelope are not published yet and will appear here once they are confirmed rather than estimated.

On a foundation or on wheels changes where it can go

The two paths certify differently, and the certification decides what a municipality treats the home as. Zenith is a modular home built to CSA A277, inspected as a building and financeable with a mortgage. Vista is a park model built to CSA Z241. Stone is a home on wheels built to CSA Z240 RV with a CMVSS national safety mark, road legal to tow.

For off-grid buyers this matters more than it does for anyone else, because rural and semi-rural zoning frequently permits one of these formats and prohibits another on the same parcel. Several regional districts prohibit RVs and homes on wheels as dwellings in every zone while permitting a modular home on a foundation.

Off-grid as a backyard unit

An off-grid backyard suite is a different problem from an off-grid home on rural acreage. On a serviced urban lot the question is rarely whether power exists, it is whether connecting to it is worth the trench, the permit and the service upgrade. Going off-grid or partly off-grid avoids that cost.

What it does not avoid is zoning. Municipalities regulate a second dwelling on the lot regardless of how it is powered, and the size, siting and parking rules apply either way. Check the lot before you specify the system.

Where you are allowed to build one

Off-grid legality is decided locally, not nationally. Three separate rules bind at once: whether zoning permits the dwelling at all, whether the building code permits the water and waste systems you want, and whether the health authority will approve on-site sewage. All three vary by municipality.

Many of the figures circulating on builder blogs are years out of date. The provincial, state and city pages on this site cite the bylaw or code section each figure comes from, so you can check them against the source rather than taking them on trust.

Buying an off-grid home: a new build or a listing

Most searches for off-grid homes for sale end on real-estate listings: existing houses and cabins, usually on rural acreage, running whatever systems the previous owner installed. That is a different purchase from a new build. With a listing you inherit someone else's array, battery bank, water source and septic approval, which are the parts that decide how an off-grid home performs.

A KYRAX home is built to order rather than listed. If you own land or are about to buy it, the order of work is the parcel first, then the format that parcel permits, then the systems. The land comes from a listing or an agent. The home that goes on it is the part we build.

An off-grid cabin you can legally live in

What most people mean by an off-grid cabin is a small, self-sufficient home on rural land. Cabin describes the use, not the certification, and the certification is what a municipality looks at. A modular home built to CSA A277 and set on a foundation is inspected as a building. A park model is built to CSA Z241. A home on wheels is certified as a recreational vehicle.

That difference decides whether the cabin can be lived in. In the Thompson-Nicola Regional District in the BC interior, the zoning bylaw prohibits recreational vehicles as dwellings in every zone, including on a temporary basis, while a modular home on a foundation is treated as a building. Check the parcel before you choose the format.

Off-grid cabin kits versus a finished build

A cabin kit ships some or all of the structure and leaves the rest to you or your contractor. For an off-grid home, the rest is the work that decides whether it functions: the electrical system that ties the array and batteries together, water storage with freeze protection, a waste system the health authority will approve and, for most shell kits, the insulation and air sealing.

KYRAX does not sell kits. We build finished homes in the factory, with the off-grid systems specified before construction starts. The kits versus turnkey guide below compares the two paths on total cost, including the line items a kit price leaves out.

04 — Common questions

Frequently asked questions

What does 'off-grid ready' mean?

It means the home is built to accept solar panels, battery storage, water collection and filtration, and a composting toilet, with those systems specified before the build starts rather than retrofitted afterwards. Choosing the capacity at design time is what keeps the systems, the envelope and the electrical layout consistent with each other.

How much does a full off-grid system cost?

It is quoted at design time, because the array, battery bank and water storage are sized to your site and your loads rather than sold as one fixed package. A home on a shaded northern lot and a home on an open southern slope do not need the same system and should not be quoted the same price. Package figures will be published on this page once they are confirmed.

How much solar does a tiny home need?

There is no single answer, and any builder quoting one without asking about your site is guessing. The array is sized from your winter sun hours, your daily load in kilowatt-hours, and how many days of autonomy you want the battery bank to carry. Heating is usually the load that decides it.

Can an off-grid home be used year-round in Canada?

Yes. Cold-climate insulation, freeze protection for water lines and tanks, and a backup heat source that works when the batteries are low are all part of the design rather than add-ons. The envelope does more of the work than the array does.

Is living off-grid legal?

It depends on the municipality, not the country. Zoning decides whether the dwelling is permitted, the building code decides which water and waste systems are allowed, and the health authority decides on-site sewage. Some jurisdictions permit an off-grid modular home on a foundation while prohibiting a home on wheels as a dwelling anywhere in the same area.

Can you get a mortgage on an off-grid home?

On a foundation, often yes. Zenith is built to CSA A277, which is inspected as a building and treated as real property, and that is the classification lenders look for. Homes on wheels are financed as personal property instead, which is a different product at a different rate.

Do you have off-grid homes for sale?

We build self-sufficient homes to order rather than holding finished inventory, because each home's power, water and waste systems are sized for the site it is going to. If you are after an existing off-grid house with land, that is a real-estate listing. If you already have land or are buying it, check what the parcel allows first.

Can a KYRAX home be used as an off-grid cabin?

Yes, if the format suits the parcel. A modular home on a foundation is inspected as a building, which is how zoning treats a house. A home on wheels is certified as a recreational vehicle, and some districts do not allow those to be lived in at all. Choose the format after checking the parcel, not before.

Do you sell off-grid cabin kits?

No. We build finished homes, with the power, water and waste systems specified before construction. A kit leaves those systems, and with most shell kits the insulation and air sealing too, to the buyer. That is the work that decides whether an off-grid home holds up in winter.

What is the cheapest way to go off-grid?

Start with the format the parcel permits, because a home you cannot legally live in is the most expensive outcome. Then stage the systems: specify the capacity at design time and install the full array and battery bank later. The affordable tiny homes page covers the lower-cost end of the lineup.
