Overview: Cost Elements, Opportunities & Barriers
Establish a shared definition of affordability (price vs payment vs lifecycle), align on a representative local baseline project type, and introduce the full end-to-end housing cost structure so later sessions stay grounded in mechanisms and numbers rather than anecdotes.
How this fits in the series
Builds on: none — this is the starting point
Leads to: A2–A11
Core concepts and execution implications
- Affordability must be defined before it can be improved (price, payment, lifecycle).
- Can state which definition they're optimizing and why.
- Housing cost is layered; each lever sits in a specific cost element.
- Can place any idea into the cost structure and discuss tradeoffs cleanly.
- Local baseline matters; abstractions without a baseline mislead.
- Can reference a shared baseline project when debating costs and levers.

The framework spans three stages (Build, Finance, Operations) with cost elements, cost reduction opportunities, policy levers, and 9 model dimensions.
How to use this page in 90 seconds
- Skim the cost elements to see where housing costs actually hide (Tables 1 & 2 below).
- Use the sessions map at the bottom to see what's coming in A2–A11.
- Use the AF Explorer for drill-down; this page is the teaching layer, not the reference database.
The three-table framework
The framework organizes housing cost analysis into three interconnected views.

Table 3: Barriers & Levers — What blocks savings
71+ specific barriers mapped to CROs—too large to display inline.
Each barrier entry includes: CRO ID, barrier description, barrier short name, barrier type, scope, and the authority who can act. The full table is available as a separate reference.
How we will use this framework
In each session we'll focus on a few Cost Elements - understanding where the money goes - and explore the related Cost Reduction Opportunities and Barriers & Levers. The framework is large and we won't be able to discuss everything, so we'll prioritize based on where we see the biggest opportunities for impact.
Baseline project archetype
A shared reference point so cost discussions stay grounded.
Throughout this series we'll reference a baseline project: a small-lot detached or attached home (townhome/duplex), roughly 1,200–1,600 sq ft finished, built at modest density (8–16 units per acre) in the Northern Colorado / Front Range area. The archetype assumes conventional wood-frame construction, municipal utilities, and standard code compliance. Dollar figures in session pages are calibrated to this archetype; adjust for your own context as needed.
