Land Value Assessment: Finding Hidden Density Potential
Bill 44 created millions of dollars in unrealized land value across Metro Vancouver overnight. Here is how to identify lots where the density potential exceeds what the current owner thinks they have.

When Bill 44 passed, it quietly changed the value equation on hundreds of thousands of single-family lots across BC. A lot that was worth $1.2M as a single-family teardown may now be worth $1.4–$1.6M as a multiplex development site — but most owners do not know it yet. That gap is where the opportunity lives.
The Residual Land Value Method
Professional developers do not value land by comparing it to neighbouring sales of similar houses. They use residual land value — working backwards from the end product. The formula is simple: total revenue from the finished units minus all development costs (construction, soft costs, financing, profit margin) equals the maximum you can pay for the land and still make the deal work.
Example: a 6-unit multiplex in Burnaby generates $4.5M in sales revenue. Total development costs (excluding land) are $2.1M. Developer requires an 18% margin ($810,000). Residual land value = $4,500,000 - $2,100,000 - $810,000 = $1,590,000. If the current owner thinks their lot is worth $1.2M based on comparable house sales, there is a $390,000 gap that benefits both parties.
What Creates Hidden Value
Several factors create situations where a lot's development value significantly exceeds its current market value as a single-family site:
- Transit proximity: Lots within 400m of a frequent transit corridor qualify for 6 units instead of 4. That extra 50% in unit count can add $200,000–$400,000 in residual land value.
- Corner lots: Two street frontages often allow more flexible building placement and better unit layouts. Some municipalities offer corner lot bonuses on FSR.
- Oversized lots: A 7,000–8,000 sq ft lot with higher FSR capacity may support larger units that sell at a premium, even with the same unit count.
- Neighbourhood trajectory: Lots in areas where new development is already occurring sell faster and at higher per-square-foot prices because buyer confidence is established.
The Assessment Gap in Metro Vancouver
BC Assessment values still lag the reality of Bill 44 density in most cases. A lot assessed at $1.1M for property tax purposes based on its single-family use may have a development value of $1.4M+ under the new zoning. This creates an opportunity for both buyers and sellers — sellers get more than they expected, and developers pay a premium but still make the numbers work because the added density covers the higher land cost.
The gap is largest in areas where few multiplex projects have been completed — there are no comparable sales to push land values up yet. As more projects complete and sell, land prices in those areas will adjust upward. The early mover advantage is real and it is time-limited.
How to Screen for Opportunity
Fort screens lots using a five-factor model: (1) lot size and dimensions, (2) FSR capacity, (3) transit proximity and unit count potential, (4) comparable sale prices for new construction in the area, and (5) current asking price or BC Assessment value relative to calculated residual value. When the residual value exceeds the asking price by 15%+, we have a deal worth pursuing.
If you own a single-family lot and want to know what your land is really worth under current multiplex zoning, we offer a free assessment. We will run the residual land value calculation based on your specific lot dimensions, zoning, and local market conditions — and give you a number you can use to make an informed decision about selling, partnering, or developing.
