# Buying an Older Heritage Mountain Home: What to Inspect (2026) > What to inspect on an older Heritage Mountain home in Port Moody: roof, Poly-B plumbing, panel, drains, retaining walls and slope, the 2026 tree bylaw, strata depreciation reports, and how to set subjects. Printable checklist. **Source:** https://soldbycraig.ca/blog/buying-an-older-heritage-mountain-home-what-to-inspect/ **Author:** Craig Johnston, REALTOR® (BC Licence V99960) · Royal LePage Elite West **Site:** https://soldbycraig.ca --- October 17, 2026 · For Buyers · Heritage Mountain, Port Moody # Buying an Older Heritage Mountain Home: What to Inspect Heritage Mountain is an established hillside neighbourhood. For a buyer that means two inspections in one: a house that has had years to age, and a sloped lot that has to manage water and soil so the house stays healthy. Here is what to check, in what order, which questions belong to a specialist rather than the home inspector, and the Port Moody rules — permits, trees, strata reports — that decide what you can fix later. By **Craig Johnston, REALTOR® V99960** · Royal LePage Elite West · 47+ year Tri-Cities resident Quick Answer On an older Heritage Mountain home, inspect **the house** and **the hillside** as two separate jobs. For the house, focus on the systems that wear out: the roof, windows and building envelope, the plumbing (including grey polybutylene “Poly-B” pipe, which many insurers now restrict), the electrical panel, the furnace and hot water tank, and the perimeter drains and sewer line, which need a camera scope. For the hillside, look hard at retaining walls, drainage from uphill lots and the driveway, and bring in a **geotechnical engineer** if a wall is moving or you plan to build. Before you write, pull the **City of Port Moody permit history**. Before you count on a view, read Port Moody’s **2026 Tree Protection Bylaw** — a permit is now needed to remove most trees 30 cm or wider on any private lot. For a townhome, the **depreciation report and two years of strata minutes** matter as much as the inspection. ## Why an older hillside home needs its own inspection plan Heritage Mountain is the hillside above Newport Village and Inlet Centre in Port Moody. Most homes that come up for sale here are resale homes on sloped lots with mature landscaping; new detached construction on the mountain is uncommon and usually means a rebuild on an existing lot. It also means you are buying a house that has been through many West Coast winters, sitting on a lot that has to move a lot of rainwater past it. The year built varies from street to street, and so does the slope. So never assume an age for a Heritage Mountain home. Start with the year built, the City’s permit history and the dates of every major replacement. A home that has had its roof, plumbing and drainage redone is a very different purchase from one still on its original systems, even when the listing photos look the same. For price context: in September 2026, the Greater Vancouver REALTORS® benchmark for a typical detached home on Heritage Mountain was $1,933,800 (−5.0% year over year), and the townhouse benchmark was $1,098,100 (−1.6%). A benchmark describes a typical home, not an average and not any specific listing, and with only 4 detached sales in the month, the figure can move a lot from one month to the next. On older homes, condition is often what separates one sale from the next — which is why the inspection carries so much weight. The full numbers are in my [Heritage Mountain market report](/heritage-mountain-market-report/) and the [2026 price bands](/heritage-mountain-price-bands-2026/). ## Step one: the paper trail, before you book the inspector The cheapest inspection is the one you do at a desk. Before an offer, I want three things in hand. - **Replacement dates.** Ask the listing agent when the roof, windows, plumbing, furnace, hot water tank and perimeter drains were last replaced or serviced, and whether there are invoices. “Updated” in a listing can mean a new kitchen or a new roof; only one of those keeps the rain out. - **The Property Disclosure Statement.** In BC, sellers usually make their disclosure on a Property Disclosure Statement (PDS), but they can provide a “Property No Disclosure Statement” instead. BCFSA advises buyers to ask for a PDS as a condition of the offer. Sellers have a duty to disclose known material latent defects — defects you could not find with a reasonable inspection — and licensees must disclose them too. A PDS reflects what the seller knows; it is not a warranty. - **City of Port Moody records.** The City runs an online **Property Information Portal**, and its Building Division (604-469-4534, buildingpermits@portmoody.ca) handles permit questions. The City’s own residential permit guide advises homeowners to check the approved plans at City Hall, if available, because they show what earlier permits allowed. Why the records matter on this mountain: Port Moody requires a building permit to finish an unfinished area such as a basement, to build a retaining wall more than 1.2 m (4 ft) high, and for most decks higher than 600 mm (2 ft) above grade, and a plumbing permit to install or alter plumbing fixtures or piping. Many Heritage Mountain homes have finished basements and some have suites. A finished basement is not the same as a permitted one, and a suite is not the same as a permitted secondary suite. If the numbers only work with rental income, confirm the permit status before you rely on it. ## The house: systems that age ### Roof, gutters and downspouts Ask the roof’s age and material, then ask the inspector how they will view it. A home inspection in BC is a visual, non-invasive look at accessible areas, and on a steep lot with a high roofline “accessible” can be limited. If the report says the roof was viewed from the ground, and the roof is old, a roofer’s opinion during the subject period is reasonable. Follow every downspout: does it run into a perimeter drain, a storm connection, or straight onto the slope? ### Windows and the building envelope Original windows tend to show their age as fogged double-glazed units (a failed seal), soft or stained sills, and staining below the frame. Look closely where decks, balconies and roof lines meet the walls, since that is where flashing details fail. Ask whether the inspector uses a moisture meter or thermal camera, and read those readings in the report. Opening walls to test is beyond a home inspection; if the visual signs point to water getting into the walls, that is a job for a building envelope consultant. ### Plumbing and Poly-B Polybutylene (“Poly-B”) is a flexible plastic supply pipe, most often grey, usually stamped **PB2110** or **CSA-B137.8**, that was widely used in Canadian homes from 1978 to the mid-1990s. It tends to fail at the fittings and from the inside, without warning. Look for it at the hot water tank, under sinks, at the water meter and in any unfinished area — but a missing stamp does not rule it out. The insurance consequence is the part buyers miss. Insurers handle Poly-B differently: some charge a higher premium or a higher water-damage deductible, some exclude water damage from plumbing failures, and some decline to insure the home at all. Where a home has been partly replumbed, insurers may ask what share of each pipe type remains. So get an actual insurance quote, with the inspection findings in hand, **during your subject period** — not after subjects are removed. If the seller says the home was replumbed, ask for the invoice and the plumbing permit. ### Electrical panel and wiring The inspector will note the panel’s make, its rated capacity and any visible defects. If the panel is original, or the report flags the panel or the wiring, have a licensed electrician look before subjects come off. Two practical questions for that electrician: is there capacity for what you plan to add, such as a heat pump or an EV charger, and is there anything your insurer will want to know about? ### Furnace, heat and hot water The data plate on a furnace or hot water tank shows when it was made. Ask for service records, check that the venting is intact, and note whether any heat pump or air conditioning was added with a permit. ### Asbestos and other hidden materials Licensed home inspectors in BC cannot assess specialized environmental hazards such as asbestos or mould. WorkSafeBC says asbestos is found in more than 3,000 common building materials, including vinyl and linoleum flooring, stucco, drywall mud and roof felt, and advises anyone planning to renovate or demolish a home built before 1990 to plan for asbestos testing and safe removal first. If you are buying with renovation plans, build that testing into the plan and the budget. ### Perimeter drains and the sewer line The perimeter drain (drain tile) around the foundation carries groundwater away; when it clogs or collapses, the first sign is often a damp basement. The general inspection cannot see inside pipes, so on an older Heritage Mountain home I recommend a **camera scope** of the perimeter drains and the sanitary sewer line by a drainage contractor, and asking the seller for any cleaning or repair records. Ask the City where its responsibility for the sewer connection ends and yours begins. ## The hillside: walls, slope, drainage and the driveway The lot is part of the structure on Heritage Mountain. - **Retaining walls.** Find every wall and work out who owns it — your lot, a neighbour’s, a shared line or public land. In Port Moody a wall retaining more than 1.2 m of soil needs a building permit, so for a tall wall look for the permit and any engineer’s drawings; where a registered professional designed the structural or geotechnical work, the City requires letters of assurance. Warning signs: leaning or bulging faces, cracked or separated blocks, rotting timber, soil washing out from behind, and water seeping through a wall with no drainage path. - **Drainage and slope.** Look at where water goes, ideally in the rain. Watch for water from uphill lots crossing the property, low spots against the foundation, soggy lawn areas in dry weather, and cracks in foundation walls or the garage slab. - **The driveway.** Steep driveways crack, and a clogged trench drain at the garage door sends water into the garage. Check the drain, the slope and the surface, and think about winter access on the steepest grades. **If you plan to build, add on or regrade:** Port Moody’s Official Community Plan includes a *Hazardous Lands and Steep Slopes* development permit area (DPA 5). Ask the City whether the lot falls inside it before you firm up, because new work there can require a development permit and professional reports before a building permit. The City’s building permit guide also requires a contoured survey by a BC Land Surveyor for lots with slopes greater than 15%. When to call a geotechnical engineer A home inspector can tell you a wall is leaning. A **geotechnical engineer** registered with Engineers and Geoscientists BC can tell you why, and what it will take to fix it. Bring one in when a retaining wall shows movement, when cracking suggests settlement, when water is seeping from the slope, or when you plan to build a wall, an addition, a pool or significant regrading. They are often booked out, so talk to one before you write the offer and set the subject period to fit. ## Trees and views: what Port Moody’s 2026 bylaw changes Port Moody adopted the **Tree Protection Bylaw, 2026, No. 3531** on March 10, 2026. It replaced the earlier bylaw, and the biggest change for Heritage Mountain buyers is reach: a Tree Management Permit is now required to remove a tree on *any* private property, single detached lots included, when the tree is: - 30 cm or more in diameter at breast height (measured 1.4 m above the base); - 10 cm or more and in an environmentally sensitive area or riparian management zone; - 10 cm or more and one of the protected native species (arbutus, cascara, Pacific dogwood, Pacific yew, shore pine, western white pine); - 10 cm or more on a property being developed; or a replacement tree, a retained tree, or a tree protected by covenant. Three details matter for view buyers. First, the bylaw’s listed grounds for a removal permit cover dead, hazardous and conflicting trees — roots in services, trees within 2 m of a foundation, conflicts with approved construction — and a view is not one of them. Second, **topping** a tree is treated as damage unless an arborist recommends it to reduce risk and the City accepts that. Third, a tree whose trunk crosses a property line is a shared tree, and removing it needs the neighbour’s written consent. Pruning to good arboricultural practice does not need a permit, and replacement planting is required in nearly all removal cases. The practical rule: price a home on the view it has today, not the view it might have if a tree came down — yours or a neighbour’s. My [Heritage Mountain view homes guide](/heritage-mountain-view-homes-guide/) covers how sightlines differ around the hillside. ## Townhomes: strata or freehold changes who pays Townhouse stock on Heritage Mountain is limited, and older complexes need a second kind of inspection: the strata corporation’s paperwork. In a strata, the roof, exterior walls, drainage and retaining walls on common property are usually the strata’s to maintain and pay for, shared by every owner. Confirm what is common property and limited common property in the bylaws and strata plan, then read: - **The Form B Information Certificate** — the current monthly fees and attached budget, rules and depreciation report. It is a snapshot of the strata on the day it was issued. - **The depreciation report.** Since July 1, 2024, BC strata corporations with five or more lots must get one on a five-year cycle and can no longer defer it with an annual three-quarter vote; Metro Vancouver stratas with no report, or only one received before December 31, 2020, had until July 1, 2026 to get one. Compare the timing of big items — roofs, envelope, piping, paving — with the contingency reserve. - **At least two years of minutes**, plus the bylaws, rules and financial statements. In minutes, look for repeat leaks, plans to replace roofs, windows or piping, drainage or retaining wall problems, insurance claims, and any talk of a special levy. Who pays an approved special levy is set by your contract, so it has to be addressed in the offer. Still inspect the unit itself: the strata does not maintain everything inside your walls. On a freehold home there is no strata to share the bill. The whole roof, every wall and the full length of the drains are yours. ## How to read the inspection report and set your subjects Hire a licensed inspector. Consumer Protection BC licenses home inspectors, and licensed inspectors must carry insurance and give you a written contract and a written report; check the licence on Consumer Protection BC’s site before you book, and ask what is included. Know the limits too: inspectors do not perform destructive testing, give repair cost estimates, assess asbestos or mould, or decide value or insurability. Those are the gaps your specialists fill. When the report arrives, it helps to sort the findings into four piles: - **Safety** — electrical hazards, venting problems, failing walls or stairs. - **Water** — active leaks, signs of moisture in walls or the basement, drainage pointing at the foundation. - **Big systems near end of life** — roof, Poly-B, panel, furnace, perimeter drains. - **Maintenance** — caulking, gutters, worn finishes. This pile rarely moves the price; every older home has one. Piles one to three get a specialist’s opinion or written quote before subjects come off. The written report and those quotes — not the verbal walk-through — are what support a renegotiation or a decision to walk away. For the subjects themselves, a typical older-hillside offer includes inspection, PDS review, financing, insurance and, for a townhome, strata documents. Before you write, check how quickly the inspector, drainage contractor and any engineer can attend, and set the dates to fit. My [guide to inspection subjects in BC](/blog/inspection-subjects-bc-coquitlam-buyer-guide-2026/) explains the options once the report is in, and [which inspections you actually need](/blog/home-inspections-you-actually-need-bc/) covers the add-ons in more depth.

Only visually. A licensed BC home inspection is a visual, non-invasive look at accessible areas, so the inspector can report a leaning, cracked or poorly drained wall but cannot tell you why it is moving or whether the slope is stable. That takes a geotechnical engineer registered with Engineers and Geoscientists BC. In Port Moody a wall retaining more than 1.2 m of soil needs a building permit, so for a tall wall also ask the City for the permit and any engineer’s drawings. ### Will my insurer cover an older Heritage Mountain home with Poly-B plumbing? It depends on the insurer. Some charge a higher premium or water-damage deductible, some exclude water damage from plumbing failures, and some decline to insure homes with Poly-B at all; partly replumbed homes may be asked what share of each pipe type remains. Poly-B was widely used in Canadian homes from 1978 to the mid-1990s, so get a real insurance quote with the inspection findings in hand during your subject period, before you remove subjects. ### Can I remove a tree to open up the view from a Heritage Mountain home? Not freely. Port Moody’s Tree Protection Bylaw, 2026, No. 3531, adopted March 10, 2026, requires a Tree Management Permit to remove trees 30 cm or more in diameter at breast height on any private property, including single detached lots, and smaller trees in some cases. The bylaw’s grounds for a removal permit cover dead, hazardous and conflicting trees, not views; topping counts as damage unless an arborist recommends it to reduce risk; and a tree whose trunk crosses the property line needs the neighbour’s written consent. Price a home on the view it has today. ### How do I find out what permits were taken out on a Port Moody house? Start with the City of Port Moody’s online Property Information Portal, then contact the Building Division at 604-469-4534 or buildingpermits@portmoody.ca. The City’s residential permit guide also suggests checking the approved plans at City Hall, if available. Look in particular for permits for a finished basement, a secondary suite, retaining walls over 1.2 m, decks and plumbing work. ### When should I hire a geotechnical engineer instead of relying on the home inspector? When a retaining wall shows movement, when cracks in the foundation or slab suggest settlement, when water is seeping from the slope, or when you plan to build a wall, an addition, a pool or significant regrading. If you plan new work, also ask the City whether the lot is in Port Moody’s Hazardous Lands and Steep Slopes development permit area (DPA 5), which can require a development permit and professional reports. Engineers are often booked out, so line one up before you write the offer. ### What should I read before buying an older Heritage Mountain townhome? The Form B Information Certificate, the depreciation report, at least two years of strata minutes, the bylaws and rules, and the financial statements and budget. Since July 1, 2024, BC stratas with five or more lots must get a depreciation report every five years and can no longer defer it by a three-quarter vote. In the minutes, look for repeat leaks, roof, window or piping replacement plans, drainage or retaining wall problems and any talk of a special levy — and remember the contract decides who pays a levy that is already approved. ### Is the Heritage Mountain benchmark price a fair guide to what an older home is worth? Only as context. In September 2026 the Greater Vancouver REALTORS® benchmark for a typical detached home on Heritage Mountain was $1,933,800, but a benchmark describes a typical home, not any specific one, and with only 4 detached sales that month it can move a lot. For an older home, I price from comparable recent sales and adjust for condition, which is where the inspection findings come in. ## Sources & methodology Every rule on this page comes from the source listed.
