Depreciation Reports & Reserve Funds
A depreciation report is the single most important document for any strata buyer. It inventories every major building component, estimates remaining useful life, and maps out a 30-year funding plan for the contingency reserve fund. If the CRF is underfunded, special levies follow. This guide covers the legal requirements under BC's Strata Property Act, who can prepare a report, what it costs, how to read one, and the red flags that signal trouble ahead.
Key Topics
Building Inventory & Life Estimates
A depreciation report catalogues every major building component — roof membrane, siding, plumbing risers, electrical panels, HVAC systems, decks, windows, and common area finishes. Each item gets a remaining-life estimate and a replacement cost projection. The result is a complete picture of what the building will need over the next 30 years.
Legal Requirement Under the SPA
Section 94 of the Strata Property Act requires every strata to obtain a depreciation report within 2 years of creation, then every 5 years after that. A strata can vote to opt out with a 3/4 vote — but the CRF must still be funded, and informed buyers will flag the absence of a report as a red flag during due diligence.
Qualified Professionals Expanded
As of October 27, 2025, BC expanded who can prepare depreciation reports. Engineers and architects always qualified. Now architectural technologists and applied science technologists (under BC Reg 238/2018) can also prepare them. This should reduce costs for small stratas that struggled to find affordable professionals.
The Contingency Reserve Fund (CRF)
Section 93 of the SPA requires every strata to maintain a CRF and contribute at least 10% of the annual operating budget each year. The CRF is the strata's savings account for major repairs. The depreciation report tells you whether the CRF balance is adequate — or whether special levies are looming.
Red Flags That Signal Trouble
A CRF underfunded by more than 30% relative to the depreciation report's recommendation is a warning sign. Other red flags: deferred maintenance items listed as urgent, end-of-life components within 5 years with no funding plan, and a strata that has voted to opt out of obtaining reports entirely.
Consequences of Ignoring Reports
Stratas that defer maintenance or underfund the CRF face compounding costs: emergency repairs cost 30-60% more than planned replacements, special levies erode owner equity, resale values drop when buyers see thin reserves, and council members can face personal liability for failing to maintain the building.
Major Building Components & Typical Lifespans
Every depreciation report catalogues these systems. Replacement timing and cost drive your CRF funding requirements.
| Component | Typical Lifespan | Replacement Cost (Small Multiplex) | Notes |
|---|---|---|---|
| Roof membrane (torch-on / SBS) | 20-25 years | $15,000-$35,000 | Flat roofs shorter; sloped roofs longer |
| Siding / cladding | 15-25 years | $20,000-$50,000 | Vinyl lasts longer; wood needs more maintenance |
| Windows & doors | 20-30 years | $25,000-$60,000 | Double-pane seals fail before frames |
| Plumbing (drain/waste/vent) | 40-50 years | $30,000-$80,000 | Cast iron shorter; ABS/PEX longer |
| Plumbing (supply piping) | 30-50 years | $15,000-$40,000 | Copper lasts longest; polybutylene must be replaced |
| Electrical (panels & wiring) | 30-40 years | $10,000-$25,000 | Aluminum wiring flagged as risk |
| HVAC systems | 15-20 years | $8,000-$20,000 per unit | Heat pumps increasingly common in new builds |
| Hot water tanks / boilers | 10-15 years | $3,000-$8,000 | Tankless lasts 20+ years |
| Decks & balconies | 15-25 years | $5,000-$15,000 | Waterproof membrane is the critical component |
| Parkade / parking surfaces | 20-30 years | $10,000-$30,000 | Concrete requires sealing every 5-7 years |
| Common area finishes | 10-20 years | $5,000-$15,000 | Flooring, paint, lighting, lobbies |
| Site drainage / perimeter | 25-40 years | $8,000-$25,000 | French drains, sump pumps, grading |

CRF Funding Adequacy
The depreciation report compares your actual CRF balance against the recommended balance. Here is how to interpret the gap.
Well-Funded
>70%
of recommended balance
Special levies are unlikely in the planning horizon. The strata can handle most major repairs from reserves. Contributions may even decrease if the fund grows faster than projected.
Adequate
40-70%
of recommended balance
The strata can handle routine repairs but may need a small special levy if a major component fails early. Council should consider increasing annual contributions to close the gap over 5-10 years.
Underfunded
<40%
of recommended balance
Special levies are probable within 3-5 years. Buyers should factor $10,000-$30,000+ per unit into their purchase calculations. Negotiate the price down or request the strata increase contributions before closing.
How to Read a Depreciation Report
Do not be intimidated by the length. Focus on these sections in order and you will know whether the building is financially healthy.
Executive Summary
Start here. It gives you the overall building condition rating, the CRF funding status, and any urgent recommendations. If the summary says the fund is adequate, the details are less critical. If it flags concerns, dig deeper.
Component Inventory Table
Scan for any component rated 'poor' or with fewer than 5 years remaining life. These are the items most likely to trigger near-term spending. Pay special attention to the roof, building envelope, and plumbing — the three most expensive systems to replace.
Funding Adequacy Comparison
This is the most important table. It shows the recommended CRF balance at 5-year intervals alongside the projected actual balance. If the actual line diverges from the recommended line by more than 30%, the strata is heading toward special levies.
30-Year Cash Flow Model
This shows year-by-year projected expenditures and CRF contributions. Look for 'spike years' where multiple expensive components need replacement simultaneously — these are the years most likely to require special levies if the CRF is not adequately funded.
Recommended Annual Contributions
Compare the report's recommended annual CRF contribution against what the strata is currently collecting. If there is a gap, ask council whether they plan to increase contributions. A council that ignores the recommendation is setting up future owners for levies.
Assumptions & Limitations
Every report lists the assumptions used — inflation rate, interest rate on CRF investments, whether destructive testing was done on the envelope. Note whether the inspector accessed all areas or if certain components were not inspectable. Inaccessible areas represent unknown risk.
Depreciation Report Costs by Building Size
Cost depends on the number of units, building complexity, and whether the building envelope requires invasive testing. Updates (every 5 years) typically cost 50-70% of the initial report.
| Building Type | Initial Report | 5-Year Update | Per-Unit Cost (Initial) |
|---|---|---|---|
| Duplex (2 units) | $3,000-$4,500 | $1,800-$3,000 | $1,500-$2,250 |
| Triplex (3 units) | $3,500-$5,500 | $2,000-$3,500 | $1,167-$1,833 |
| Fourplex (4 units) | $4,000-$6,500 | $2,500-$4,000 | $1,000-$1,625 |
| Small building (5-8 units) | $5,000-$8,000 | $3,000-$5,500 | $625-$1,600 |
| Mid-size (9-20 units) | $8,000-$15,000 | $5,000-$10,000 | $400-$1,667 |

October 2025 Regulatory Change
Effective October 27, 2025, BC Regulation 238/2018 expanded who can prepare depreciation reports. Architectural technologists (R.A.T.) and applied science technologists (A.Sc.T.) now qualify alongside engineers and architects.
Before Oct 2025
Engineers (P.Eng.) and Architects only
After Oct 2025
Engineers, Architects, R.A.T.s, and A.Sc.T.s
Impact: More professionals competing for small strata work means lower costs and faster turnaround. The Superintendent of Real Estate sets practice guidelines that all qualified professionals must follow.

Frequently Asked Questions
What is a depreciation report?
A depreciation report is a professional assessment that inventories every major building component, estimates its remaining useful life, and creates a 30-year funding plan for the strata's contingency reserve fund. It is legally required for all BC stratas.
Think of it as a health check for the building. A qualified professional physically inspects the property — climbing on the roof, examining the mechanical room, checking the building envelope, looking at plumbing and electrical systems. For each major component, they estimate the remaining useful life (e.g., roof membrane has 8 years left), the replacement cost in current dollars, and the inflation-adjusted cost at the time replacement will be needed. All of this feeds into a 30-year cash-flow model that tells the strata exactly how much money it should be setting aside annually. The report also compares the recommended CRF balance against the actual balance, highlighting any funding gaps.
When is a depreciation report required?
Under SPA s.94, a strata must obtain its first depreciation report within 2 years of the strata plan being filed at the Land Title Office, then update it every 5 years. A 3/4 vote can opt out, but the CRF must still be funded.
The 2-year clock starts when the strata plan is deposited at the Land Title Office, not when units are sold. For a new multiplex development, this typically means the developer commissions the first report before turnover to owners. After that, the strata council is responsible for commissioning updates every 5 years. Opting out requires a 3/4 vote at a general meeting — in a triplex, that means all three owners must agree. Even if a strata opts out, it must still contribute at least 10% of operating costs to the CRF annually. Buyers reviewing strata documents should treat an opt-out as a significant risk factor, because it means there is no professional assessment of the building's repair timeline.
Who can prepare a depreciation report in BC?
Engineers, architects, and — as of October 27, 2025 — architectural technologists and applied science technologists registered under BC Reg 238/2018. The expansion was specifically intended to increase supply and reduce costs for smaller stratas.
Before October 2025, only Professional Engineers (P.Eng.) and registered Architects could prepare depreciation reports. This created a bottleneck, especially for small stratas that could not justify the cost of hiring a large engineering firm. The regulatory change under BC Reg 238/2018 now allows Registered Architectural Technologists (R.A.T.) and Applied Science Technologists (A.Sc.T.) with appropriate experience to prepare reports. The professional must carry errors and omissions insurance and follow the guidelines published by the Superintendent of Real Estate. For a small multiplex strata, this change could reduce report costs by 20-40% as more professionals compete for the work.
How much does a depreciation report cost?
For a small strata of 2-8 units, expect $3,000-$8,000. Cost depends on building age, complexity, number of components, and whether the professional needs to do destructive testing on the building envelope.
A brand-new fourplex with a simple building form, no elevator, and standard systems will land at the lower end — $3,000-$4,500. An older or more complex building with underground parking, multiple roof levels, or suspected envelope issues will run $5,000-$8,000. Some firms offer multi-strata discounts if several small stratas in the same development commission reports simultaneously. The 2025 expansion of qualified professionals should create downward price pressure over time. When soliciting quotes, ask whether the fee includes the 30-year cash-flow model and whether updates (the 5-year refresh) cost less than the initial report. Most firms charge 50-70% of the initial cost for an update since they already have the component inventory.
What does the report actually cover?
Every major building component: roof, building envelope (siding, cladding, windows), plumbing, electrical, HVAC, decks and balconies, parking areas, elevators (if any), common area finishes, landscaping, and site drainage systems.
The level of detail varies by component category. For the roof, the report will note the membrane type (torch-on, TPO, SBS), current condition, estimated remaining life, and replacement cost. For plumbing, it covers drain, waste, and vent piping (typically ABS or cast iron), supply piping (copper or PEX), and hot water systems. Electrical covers the main service panel, distribution panels, wiring type, and any common-area lighting. The report should also flag any building code compliance issues — for example, if the original construction used materials that are now restricted. Each component gets a condition rating (good, fair, poor), a remaining useful life estimate, and a replacement cost in both current and future dollars.
How do I read a depreciation report?
Start with the executive summary, then check the funding adequacy table. Compare the recommended CRF balance against the actual balance. A gap over 30% means special levies are likely. Then scan the component list for anything reaching end-of-life within 5 years.
A standard depreciation report has several key sections. The executive summary gives you the big picture — overall building condition and whether the CRF is adequately funded. The component inventory lists every major system with condition, remaining life, and cost. The cash-flow model shows year-by-year expenditures and CRF balances under the recommended contribution scenario. The funding adequacy comparison is the most critical table: it shows the recommended CRF balance at year 1, 5, 10, 15, 20, 25, and 30 alongside the projected actual balance based on current contributions. If the actual line falls significantly below the recommended line, the strata needs to either increase contributions or accept that special levies will be needed.
Can a strata opt out of depreciation reports?
Yes. A 3/4 vote at a general meeting can waive the requirement. But the strata must still fund the CRF at a minimum of 10% of annual operating costs. Informed buyers treat an opt-out as a red flag because it removes professional oversight of the building's condition.
Opting out was more common in the early years of the requirement, when small stratas balked at the cost. Today, with expanded professional qualifications and lower prices, there is less justification. A strata that has opted out has no independent assessment of when major components will fail or how much money should be in reserve. This means the owners are flying blind — relying on their own judgment about when the roof needs replacing or the plumbing needs upgrading. When buying into a strata that has opted out, budget for commissioning your own building condition assessment ($1,500-$3,000) so you have an independent view of upcoming costs.
