Podcast: Upzoned by Strong Towns
Date: December 17, 2025
Hosts: Norm (Director of Membership, Strong Towns) and Edward Erfurt (Chief Technical Advisor & Director of Community Action, Strong Towns)
Main Theme:
A deep-dive on a viral story about a legal, three-story home addition in Fairfax County, Virginia, that drew significant neighborhood outrage, and what this reveals about zoning, multigenerational living, neighborhood change, and the often fraught transitions facing American suburbs.

Episode Overview

This episode unpacks the controversy around a three-story "monster" addition to a single-family home in Fairfax County, VA. Although the addition was fully permitted under local zoning laws, neighbors objected fiercely, citing privacy, property values, neighborhood character, and more. Norm and Edward analyze why these issues cause such distress, what they say about broader housing challenges, and how cities can better manage gradual neighborhood change.

Key Discussion Points & Insights

1. Background of the Controversy

• The Story:

  • An existing single-family home in suburban Fairfax County received a permitted three-story addition, intended to allow for multigenerational living (grandparents, parents, children).
  • Outcry from neighbors citing privacy, sunlight loss, property values, and neighborhood character.
  • The county supervisor promised to "look into" the case, suggesting political pressure.
  • Despite complaints, the addition was “by right” under current zoning.

• Why It Hit a Nerve:

  • The area's proximity to Washington, D.C. made it more visible.
  • The built form—a modern, boxy, three-story addition—sharply contrasted with older, single-story ranch or colonial-style homes.

2. Single-family Zoning and Incremental Growth

• Discussion of "Next Increment":

  • Edward explains the Strong Towns concept of "incremental growth."
  • "If you have a one story neighborhood, everybody by right should be able to go up to two stories. And then if you’ve got two story in the neighborhood, then you should be allowed to go up to three stories." (Edward, 05:50)
  • In this case, the block had one and two-story homes, so zoning allowed for three stories; but the leap was still "jarring" next to an older one-story structure.

• Jarring Transitions:

  • The addition directly abutted a one-story house, creating a stark contrast.
  • Regulations allowed this, but the aesthetic and contextual disconnect disturbed neighbors.

3. Neighbor Complaints – Common Themes

• Setbacks & Encroachment:

  • Objections over how close the addition was to property lines—possible minor violations.
  • Privacy concerns: “If your windows were higher than my windows, then you're going to look down into my house or you're going to look down into my backyard.” (Edward, 08:37)
  • Sunlight issues: Shading of yards due to three-story wall right on the edge.

• Call for More Bureaucracy:

  • Unique twist: Some neighbors wished for the presence of a Homeowners Association (HOA), which the area lacked, demonstrating a lack of trust in local government to respond to concerns.
  • “I have never met anybody that lives in an HOA that wants to go have another HOA... That is a new one for me.” (Edward, 09:15)

4. Design and Code Review

• Architectural ‘Massing’ and Context:

  • The addition was “a highly efficient rectangle that’s going up, but architecturally not a lot going on with it.” (Edward, 15:00)
  • Lack of step-backs or design adaptation made it stick out.
  • Rarely do building permits review matters of context or aesthetics—just compliance with base regulations.
  • Code review focuses on setbacks, structure, and safety—not aesthetics or how new structures fit with their surroundings.

• Permitting Catch:

  • The addition may have narrowly violated the side-yard setback by mere inches (“Instead of 8 ft, it’s probably 7 ft 11 inches off the property line”—Edward, 29:10), forcing a possible variance process—a public hearing sure to be fraught.

5. Neighborhood Resistance to Change

• Suburban 'Stasis':

  • Neighborhoods expect nothing to change, physically or demographically, once built.
  • “...The neighborhood here is just convinced that it is and always shall be as it was.” (Norm, 21:29)
  • Any increment, even small, is perceived as a threat to the identity and value of the area.

• Financial and Emotional Arguments:

  • Neighbors framed objections in terms of financial investment: “What if we sell?” “This will drive down home values.”
  • Edward notes zoning codes never account for value/perceived financial impacts—just land use and form.
  • “I’ve rarely if ever seen a zoning code linked to a financial model and outcome. It just, it doesn’t happen.” (Edward, 25:37)

6. Multi-generational vs. Multifamily Living

• Double Standards and Definitions:

  • Large, single-structure multi-generational homes are permitted, but similar forms as multifamily (separate units) are not.
  • Quote: “There’s a double standard between multi family homes and multi generational homes.” (Norm, 34:05)
  • Strong Towns urges rethinking of these definitions: function and form matter more than arbitrary household relationships.

• Historic Precedents:

  • Discusses the New England "triple decker" as an organic, flexible approach to multi-family/multigenerational housing; families adjusting layouts over time.

7. Design Problem & Forward Thinking

• Need for Design Sensitivity:

  • Edward: Planners and building officials aren’t trained to address context and neighborliness—urban designers are needed.
  • “I would describe this as a design problem. And if we could get the design right, the neighborliness, the administrative stuff, all of that would work itself out.” (Edward, 43:00)

• Managing Neighborhood Evolution:

  • Suggests technical review, community involvement, and design standards to allow incremental change that feels organic, not jarring.

Notable Quotes & Memorable Moments

• “There are no winners in this discussion. You’ve got zoning code that is really complicated, that allows for what is conceivably the next increment of development in a neighborhood... But you do have homes that are not going to grow up in that type of structure. So it is jarring in this particular street.”
  — Edward (07:04)

• “We need to break out of being stuck in amber. We need to allow for folks to thicken up, to do those small additions, to add pieces on here.”
  — Edward (04:17)

• [On suburban expectation of stasis:] “The neighborhood here is just convinced that it is and always shall be as it was...”
  — Norm (21:29)

• “I have never met anybody that lives in an HOA that wants to go have another HOA that looks out neighborhoods and says, ‘Oh, that neighborhood is beautiful to me because there is an HOA.’”
  — Edward (09:15)

• “I would describe this as a design problem. And if we could get the design right, the neighborliness, the administrative stuff, all of that would work itself out.”
  — Edward (43:00)

• “Multigenerational living isn’t immigrant culture, it’s human culture.”
  — Norm, referencing Sheena at Strong Towns (23:09)

• On financial complaints vs code compliance:

  • “I’ve rarely if ever seen a zoning code linked to a financial model and outcome. It just, it doesn’t happen.”
    — Edward (25:37)

Conclusion

This episode explores the human, regulatory, and design challenges inherent in allowing neighborhoods to evolve in response to changing family needs and housing pressures. The Fairfax County story is not unique—it's emblematic of North American suburbs. Solutions lie in regulatory reform (towards true incrementalism), greater design sensitivity, and a cultural shift in how we perceive neighborhood change and shared living arrangements.
