Buying Acreage in Maple Ridge, Langley or Mission? What a Red Seal Plumber Checks on the Well, Septic and ALR First

By Jake Frisson, PREC*, Royal LePage Wolstencroft Realty, Red Seal plumber turned REALTOR®

Short answer: on a rural property in the Fraser Valley, the house is only part of what you're buying. You're also buying your own water supply (a well), your own sewage treatment (a septic system), and a set of land-use rules that may include the Agricultural Land Reserve (ALR). If any of those three is a problem, it can cost more than a new kitchen, and none of it shows up in the listing photos. I check all three before I talk price.

I'm Jake Frisson. I spent years as a Red Seal plumber before I became a realtor, and land and acreage is where that background earns its keep. Here's the order I work in when a buyer wants to move out to acreage in Maple Ridge, Langley, Mission or anywhere in the Fraser Valley.

Is the well actually giving enough good water?

The first question is quantity, the second is quality, and you need an answer to both before you remove subjects.

Quantity: I want to know how many gallons per minute the well can sustain, not just whether water comes out of the tap. Ask for the well construction report if there is one, and book a flow test with a qualified well or pump professional during your subject period. A well that's fine for two people may not keep up with a family of five, a suite, or a garden.

Records: the Province keeps a database called GWELLS (Groundwater Wells and Aquifers) where registered wells are recorded. Under BC rules, water supply wells drilled, altered or decommissioned after February 29, 2016 have to be registered, and the driller has to submit a construction report. Wells older than that were registered voluntarily, so an older well may simply not be in the system. Missing records aren't a deal-breaker, but they mean we lean harder on testing.

Licensing: according to the Province of BC, groundwater used only for domestic purposes (household use, pets, and a garden under 1,000 square metres) doesn't need a water licence under the Water Sustainability Act. If you plan to irrigate a bigger area, run livestock commercially, or use the water for a business, that's non-domestic use and you need a licence. If you're buying acreage for a hobby farm or a business, ask that question early.

How do I know if the well water is safe to drink?

Get it tested by an accredited lab, at minimum for bacteria (total coliforms and E. coli), and for chemicals like nitrates and arsenic. HealthLink BC recommends bacteriological testing of private wells at least once a year, and Health Canada recommends every six months. Fraser Health's own well guidance suggests bacterial testing twice a year (spring and fall) and a broader chemical panel at least every three years.

On a purchase, I want a fresh test done in the subject period, not a two-year-old result from the seller. Health Canada is clear that any E. coli in a sample means the water isn't safe to drink, and that a positive result should be confirmed and followed by disinfection and corrective work. If the test comes back with a problem, that's a negotiating point backed by a lab report, not an opinion.

From the plumbing side, I also look at the pump age, the pressure tank, any treatment equipment (UV, filters, softeners), and whether the well head is sealed, above grade, and away from surface water and the septic field.

What should I know about the septic system before buying?

Assume you're inheriting it, because legally you are. The Fraser Valley Regional District's buyer and seller guide notes that when you buy a property with a septic system, you become responsible for its health under the BC Sewerage System Regulation.

Here's what I ask for:

• An inspection by an Authorized Person. Under the Sewerage System Regulation, only an Authorized Person (a Registered Onsite Wastewater Practitioner, called a ROWP, or a professional engineer) can design, install, repair, maintain or inspect a system. A general home inspector isn't a substitute.

• The paperwork. For systems built under the current rules, the Authorized Person files a Record of Sewerage System with Fraser Health before work, and a Letter of Certification within 30 days after it's done, and gives the owner a maintenance plan. The FVRD notes that systems built before 2005 most likely don't have a maintenance plan.

• Pump-out and repair history, and where the tank and drain field actually are. A field under a driveway, a new shop, or a soggy low spot is a red flag.

• Capacity. If you plan to add a bedroom, a suite or a second home, the system has to be sized for it. Tell the ROWP what you plan to do with the property, not just how it's used today.

If a system needs repair or replacement, an Authorized Person has to do the work and handle the filings. Fraser Health's property owner Q&A (January 2024) lists a $200 administration fee with a Record of Sewerage System filing, on top of the actual design and construction cost. Get a real quote before you set your price, not after.

Is the property in the ALR, and what can I build?

Check the ALR status before you fall in love with a building plan. A lot of rural land around the Fraser Valley is in the Agricultural Land Reserve, and the rules there are set by the Provincial Agricultural Land Commission (ALC) on top of your city's zoning.

According to the ALC, most ALR properties can have one principal residence without an application if its total floor area is 500 square metres or less. An additional detached residence may be allowed without an application if there's only one existing home when construction starts, up to 90 square metres on properties of 40 hectares or less (186 square metres on properties over 40 hectares). The ALC also notes that local governments can set lower size caps, so the City of Maple Ridge, the Township or City of Langley, the City of Mission, or the regional district may have stricter rules.

What that means for buyers: if your plan is a big new house, a carriage home for parents, or a shop with a suite, confirm what's allowed with the ALC and the local municipality before you remove subjects. A buyer who assumes they can add a second home and can't has paid acreage prices for a plan that doesn't work.

How should I price an offer on acreage right now?

Price it from comparable rural sales and the real cost of the systems, not from the asking price. Acreage comps are thinner than subdivision comps, so I widen the search and adjust for lot size, usable land, water, septic and ALR status.

The market gives buyers some room right now. The Fraser Valley Real Estate Board reported 922 sales in September 2026, 4% below September 2025, with 9,763 active listings, 31% above the 10-year seasonal average. The board's benchmark price for a typical single-family detached home was $1,300,000, down 8.8% year over year, and detached homes took an average of 45 days to sell. In Mission, the September 2026 detached benchmark was $889,200, down 13.2% from a year earlier (FVREB).

Those are board-wide numbers, not acreage-specific ones, so I always pull the rural sales for the exact area. But with inventory that high, a buyer with a clean lab report, a ROWP inspection and repair quotes in hand is negotiating on facts.

Who is acreage a good fit for?

It's a great fit for people who want space, a shop, a hobby farm, or room for family, and who are comfortable owning their own water and sewage systems. It's a tougher fit for someone who wants zero maintenance or needs a short commute every day. Neither is wrong. It's just better to know before you buy.

Frequently asked questions

Do I need a water licence for a well on my acreage?

Not if the water is only for domestic use. According to the Province of BC, household use, pets and a garden under 1,000 square metres are exempt. Irrigation, commercial or other non-domestic use needs a licence under the Water Sustainability Act.

How often should well water be tested in BC?

HealthLink BC recommends bacteriological testing at least once a year, Health Canada recommends every six months, and Fraser Health suggests spring and fall. Test again after flooding, a long dry spell, or any change in taste, colour or smell.

Can a regular home inspector inspect a septic system?

Under BC's Sewerage System Regulation, inspecting a septic system is work for an Authorized Person, meaning a Registered Onsite Wastewater Practitioner or a professional engineer. I recommend booking one separately on any acreage purchase.

Can I build a second house on ALR land?

Sometimes. The ALC allows one additional detached residence without an application in some cases, up to 90 square metres on properties of 40 hectares or less, but local bylaws can be stricter. Confirm with the ALC and the municipality before you buy.

What subjects should I include on an acreage offer?

At a minimum, I'd talk with your lawyer about subjects for financing, a home inspection, a well flow test and water quality test, a septic inspection by an Authorized Person, and review of title and any ALR or zoning restrictions. Some lenders and insurers also want well and septic documentation.
