Montgomery County's planning board voted to allow duplexes, triplexes, and small apartments in single-family zones. Kevin explains...

On June 13th, 2024, theMontgomery County Planning Boardvoted unanimously to approve a set of zoning recommendations that represent the most significant shift in the county’s residential development rules in decades. If you own a home in Montgomery County, this affects you — even if you never intend to build anything.

What Actually Changed

The Planning Board approved theAttainable Housing Strategy, which transmits a set of recommended zoning modifications to the County Council for legislation. The core change: residential zones that previously permitted only single-family detached homes would now allow duplexes, triplexes, townhomes, and small apartment buildings “by right” — meaning without requiring special use permits or lengthy variance processes.

This does not mean your neighbor can immediately build a 20-unit apartment building. The proposal targets “missing middle” housing — 2-6 unit buildings on single lots — in areas currently zoned for single-family only. Single-family homes remain permitted; the change adds options, it doesn’t eliminate what exists.

Why Montgomery County Did This

Planning Board Chair Tina Patterson cited the direct connection between restrictive zoning and the county’s housing affordability crisis. The county hasdocumented a significant housing shortfall— particularly for workforce and middle-income households. With almost no undeveloped land remaining in the county’s core areas, the only way to meaningfully increase housing supply is to allow more units on existing lots. The current zoning pattern, where roughly half the county’s housing stock is detached single-family homes on large lots, severely constrains supply and keeps prices elevated.

What It Means for Existing Homeowners

The fear response from existing homeowners is understandable: will this reduce my property value? Will my quiet neighborhood suddenly have multi-unit buildings next door? Kevin’s honest take: the research on upzoning’s impact on property values is mixed and context-dependent.Lincoln Institute of Land Policy researchshows upzoning effects vary significantly based on local market conditions and the pace of actual development.

In markets where upzoning leads to significant new construction, existing property values have generally held or increased — more supply creates more activity, more amenities, and more neighborhood investment. In markets where upzoning is adopted but little actually gets built (due to financing, builder capacity, or market conditions), the effect on existing values is minimal.

For most Montgomery County homeowners, the near-term impact is likely limited. Meaningful infill development takes years to materialize even after zoning changes, and the financing and construction environment in 2024-2025 hasn’t been favorable for new small-unit development.

What Buyers Should Know

If you’re buying in Montgomery County and your purchase decision is influenced by neighborhood character — single-family feel, lot sizes, streetscape — it’s worth understanding which specific zone your target address is in and whether it falls within the proposed modified zones. TheMontgomery Planning websitehas zoning maps and the Attainable Housing Strategy documents available for review.

Frequently Asked Questions

What is the Montgomery County Attainable Housing Strategy?

A set of zoning recommendations approved by the Planning Board in June 2024 that would allow duplexes, triplexes, townhomes, and small apartment buildings in residential zones that previously only permitted single-family homes. The County Council must pass legislation to implement the changes.

Will the zoning changes lower property values in Montgomery County?

Research on upzoning’s impact is mixed. In active markets like Montgomery County, the long-term effect of increased housing supply is typically neutral to positive for property values, as more development supports neighborhood vitality. Short-term and immediate impacts are likely minimal — actual construction lags zoning changes by years.

Can my neighbor now build an apartment building next door?

The proposed changes allow small-scale infill development (2-6 units) by right in certain zones. Large apartment buildings still require separate approvals. The changes are specifically targeted at “missing middle” housing, not large-scale multifamily development.

Has the County Council passed these zoning changes into law?

As of the video date, the Planning Board vote transmitted the recommendations to the County Council for legislative consideration. Passage, amendment, or rejection are all possible outcomes. Check theMontgomery County Council websitefor current status.
