Housing and municipal planning
A housing target tells a council how much housing a community needs. It says little about how much housing the community can build. DDA tests plans, targets, bylaws, and land capacity as one delivery system, and finds the link where need stops becoming homes.
01 The delivery chain
Housing appears after a sequence of conditions. Households form and choose to stay. Land carries a designation and the right zone. Servicing reaches the site. The project pays for itself at current costs and prices. Finance is available, a builder can take the work, and approvals arrive on time. The finished unit finds an occupant who can pay for it.
In British Columbia, the official community plan sets the land-use designation. Zoning sets what someone can build. A parcel can carry a designation for housing and still sit in a zone that blocks it. DDA tests the plan and the zoning bylaw together, parcel by parcel.
02 The evidence problem
The housing needs report gives a number for five years and for twenty years. That number is a projection of need. The delivery record comes from building permits, starts, and completions, and each one measures a different point in the chain. A permit is a decision to allow. A completion is a finished unit. Many communities record permits and no completions, so permits become the proxy for output.
Vacancy data has a coverage gap. The national rental survey covers larger centres, and small communities often have no current figure. A vacancy rate from a local plan can be several years old. DDA labels these figures PROXY and states their date and source.
Census figures set the base for population and households. The census is a snapshot every five years, and a growing community moves fast between counts. DDA states the data floor of every analysis.
The built rate also hides the mix of housing forms. A community that built mostly single-detached homes and mobile homes has shown that it can deliver those forms. It has shown nothing about apartments or townhouses.
03 Where it usually breaks
Delivery rate breaks first in many small communities. A target that needs four times the historical rate needs a named mechanism: new land, new servicing, a change in zoning, a public or non-profit builder, or a financed project. Without a mechanism, the target describes a wish.
Servicing is the second break. Water and sewer capacity, and the cost of extending them, decide which parcels can build. A connection charge covers a defined list of works, and the tax base carries the rest.
Project economics is the third break. When construction cost and land cost exceed what the market pays, no builder proposes the project. Zoning changes and faster approvals do nothing for a project that does not pencil. A local builder statement about the price at which homes can be delivered is direct evidence, and a plan that assumes a lower price contains a contradiction.
Builder and trade capacity is the fourth break. A region with few builders cannot absorb a large program in one year.
The bottleneck moves. Fixing servicing exposes finance. Fixing finance exposes builder capacity. DDA reports what binds next.
04 What the work can produce
The work can produce a plan and zoning review, a delivery-rate baseline, a capacity funnel from theoretical to deliverable units, a servicing and cost analysis, a housing target test, a delivery thesis for council, and a monitor with indicators that show early if the target holds. It can also produce a review of a proposed official community plan against its own implementation evidence, before the public hearing.
A target that comes with a delivery thesis says why the system can produce the units: which sites exist, which servicing conditions hold, which policy changes reach the binding constraint, which projects work economically, and which indicators will show if the assumptions hold.
05 Connected capabilities and related thinking
This area uses Land, infrastructure, and spatial analysis, Fiscal and scenario modelling, and Evidence reconstruction. Read When a housing target is larger than delivery for a worked example. For growth that ties to jobs and land, see Economic development.
06 Bring the question
Send the target, the draft plan, the zoning bylaw, or the housing needs report. DDA will trace the target through the delivery chain and show which link limits production.
