Stay close as life changes.
A smaller home for a longtime neighbor. A first place for our grown children. More housing choices can help people stay in East Rockville instead of having to leave.
EAST ROCKVILLE’S NEXT CHAPTER
East Rockville
for more.
More housing choices for East Rockville.
Rockville is starting a new East Rockville Neighborhood Plan, replacing the neighborhood’s chapter in the 2040 Comprehensive Plan. This is our chance to shape where new homes belong—and make room for neighbors to stay, downsize, or start out near Metro and Town Center.

WHY THIS MATTERS TO US
More ways to
keep calling this home.
More housing choices can make our neighborhood work better for the people already here—and the neighbors to come.
02
Support the places we love.
More neighbors within walking distance means more potential customers for Town Center’s shops and restaurants—and future businesses on Stonestreet.
03
Put our trains to work.
Homes near Metro make it easier to drive less. Building here can also reduce sprawl, helping address climate change while giving more people access to a place we already value.
EPA: homes, transit & energy [35]FTA: why build near transit? [36]Why hometown housing matters [25]
Keeping the same zoning won’t keep the neighborhood affordable.
A modest house can still be torn down for a much larger “McMansion.” Allowing several smaller homes where they fit gives owners another choice—and gives more households a chance to live here.
Why East Rockville is a good place for more homes
We are close to Metro, MARC, Amtrak, and Town Center, yet most homes are detached houses. Maryland recognized the Rockville station area for transit-oriented development in March 2026. That designation supports the case for more homes near transit; it does not itself rezone any property.
Maryland’s housing report estimates a shortage of 96,000 homes. East Rockville can be part of the solution.

THE PROPOSAL
More homes.
In places that make sense.
Larger buildings near the station. Smaller homes on neighborhood streets. Owners choose whether to make a change.
More choices for the neighborhood. Your home is still your choice.
More homes along Stonestreet. More housing choices on neighborhood streets. Owners decide whether anything changes.
A new map. More possibilities.
The Metro property keeps its current zoning. The proposal adds capacity beside the tracks, a transition east of Stonestreet, and missing-middle choices on nearby residential streets.
Draft neighborhood-plan map using City of Rockville zoning and parcel boundaries. The city would adopt the final parcel assignments. Tap either map to zoom in.
Map key and how the draft was drawn
Rose: MXTD-85 west of Stonestreet. Purple: MXCT east of Stonestreet, north of Metro. Yellow: RMD-Infill. Blue / teal: existing MXB / MXNC. Orange: existing detached-house districts. Green: PARK. Other existing districts retain their assignments.
The maps use the same geography and colors. The Metro property is unchanged. Proposed RMD-Infill covers R-60 residential parcels within approximately ½ mile of the station’s east-side approach; existing RMD-Infill remains. The dashed ring measures straight-line distance, not a walking route. Current parks, identified public/community sites, and other districts retain their zoning. Street-label locations are checked against the saved city parcel addresses and zoning reference map.
Existing overlays and district requirements continue to apply. Final mapping follows complete parcels and includes the city’s site and infrastructure review.
| Where | Proposed zone assignments | What that means for the neighborhood |
|---|---|---|
| Metro property | Retain current zoning. | No zoning change to the Metro property. |
| West side of Stonestreet, beside the railway | Change existing MXB or MXNC properties to MXTD-85. | More homes and mixed-use opportunities close to trains. Base height: 85 feet. |
| East side of Stonestreet, north of Metro | Change existing MXB or MXNC corridor properties to MXCT. | Homes and neighborhood-serving uses, with a moderate transition toward residential streets. Base height: 75 feet. |
| Residential lots within approximately ½ mile of Metro | Change R-60 residential parcels to RMD-Infill. Retain existing RMD-Infill. | More duplexes, triplexes, eligible fourplexes, townhouses, and cottage courts under existing rules. Generally 30–40 feet, depending on housing type. |
The request: change zone assignments using districts Rockville already has. Keep current building, parking, infrastructure, and review requirements. Preserve parks, public facilities, and existing higher-density districts.
Explore each area and the detailed zoning rules
The proposal uses the ordinance adopted June 29, 2026, effective August 1, 2026. It requests map changes only, with no zoning text amendments.
MXB / MXNC → MXTD-85
More homes beside our rail connections.
Assign MXTD-85 to the existing MXB and MXNC properties between Stonestreet and the railway. This existing transit-oriented district supports apartments and mixed-use development near Metro.
- Base building height: 85 feet. Qualifying projects can receive the existing 50-foot bonus, for up to 135 feet.
- Keep current parking, use, design, infrastructure, and development-review requirements.
- The Metro property keeps its current zoning.
Transit-oriented zoning beside transit.
More households can live close to trains and Town Center, with the railway on one side of the development area.
West-side Stonestreet properties directly beside the railway; identify complete parcels in the city’s map amendment.
| District | Base height | Existing conditions and bonuses |
|---|---|---|
| MXTD-85 | 85 feet | A 50-foot bonus can allow 135 feet for qualifying projects under Table 7.3.2-1. |
| MXCT | 75 feet | A 30% height bonus can allow 97.5 feet for qualifying state-law projects under Table 7.3.3-1. |
| RMD-Infill | 30 feet: cottage courts; 35: detached homes, duplexes and triplexes; 40: townhouses and eligible fourplexes | 2,000 square feet per home at base; fourplex eligibility under §25.6.3.12(c)(3). Existing conditional density bonus remains available. |
Existing mixed-use setbacks and upper-story transitions apply where required by §§25.7.3.6–7. All use conditions, parking, tree, stormwater, historic, infrastructure, and development-review requirements continue to apply.
What does this mean for a typical residential lot?
Under RMD-Infill, a 6,000-square-foot lot has enough base lot area for three homes. An 8,000-square-foot lot has enough base area for four homes, with a fourplex also needing to qualify under §25.6.3.12(c)(3). Layouts must meet the district’s other requirements.
The plan can recommend suitable corner lots for fourplexes under the existing corner-lot provision.
How would the map changes be implemented?
- Prepare a parcel schedule: identify current and proposed districts for the west-side corridor, east-side corridor, and R-60 residential area. Retain the Metro property’s current zoning.
- Check site conditions: apply existing use, setback, height, parking, emergency access, stormwater, tree, historic, and infrastructure requirements.
- Adopt plan recommendations and a map amendment: use the existing notice, hearing, and approval process in §25.5.3.1.
- Review individual projects: retain applicable development, subdivision, APFO, and permit procedures.
Current zoning ordinance [7]Official zoning map & guide [8]City development review [27]
Ask the city to test housing capacity and infrastructure needs under these assignments. The calculator’s 500- and 1,000-home scenarios are illustrations for that discussion. Aim to complete map changes within a year of plan adoption, following the required public process.
WHAT THESE HOMES LOOK LIKE
The homes
in between.
Familiar housing types, with more than one way to live in the neighborhood.
“Missing middle” just means more options between a detached house and a large apartment building.
2–4
Homes in one building
Duplexes, triplexes, and eligible fourplexes can share a building without the scale of a large apartment complex.
↔
Townhouses
Attached homes with their own entrances offer another way to own a home while sharing less land per household.
+
Cottages & small apartments
On suitable sites, smaller homes can offer an easier place to maintain or a first home near friends and family.
Smaller homes can offer less expensive choices than a large new detached house. They won’t all be affordable to everyone, so income-restricted housing and assistance still matter.
Minneapolis: missing middle [28]NYU research review [10]
Other cities are making room for these homes
Minneapolis: its 2020 reforms allowed up to three homes on residential parcels. The city also identifies financing and building requirements as challenges to getting homes built.
Minneapolis: missing middle [28]
Portland: its 2021 Residential Infill Project expanded opportunities for duplexes, triplexes, and fourplexes, with a six-home option tied to affordability requirements.
Portland: 2021 infill reform [29]Portland: housing options today [30]
Cambridge: its 2025 changes allowed multifamily housing citywide, including buildings larger than typical missing-middle homes.
These examples show different approaches. Our proposal uses Rockville’s existing districts; it does not ask the city to copy these ordinance changes.
A STRONGER TAX BASE
More homes can grow
our tax base.
New homes bring new taxpayers as well as new service needs.
More homes can help support the services we all use.
For illustration, 500 additional homes could generate about $686,000 a year in added city property tax once built, under the assumptions below. That is additional revenue to help support our shared services, before service costs and tax credits.

AT FULL COMPLETION, BEFORE COSTS & CREDITS

600 new homes replace 100 existing homes: 500 net additional homes.

- Tax from all new homes
- $876,000
- Less tax from existing homes replaced
- −$189,800
- Net added assessed value
- $235 million
- 15-year cumulative gross revenue
- $5.15 million
Estimated additional city property-tax revenue, before service costs, capital costs, and tax credits.
Where the estimate comes from
Rockville lists a city real property-tax rate of $0.292 per $100 of assessed value. That equals 0.00292 dollars of annual city tax for each dollar of taxable assessment. County, state, and special-district taxes are not included.
Annual added city tax = [(net added homes + homes replaced) × new assessment per home − homes replaced × existing assessment per home] × 0.00292
Default: [(500 + 100) × $500,000 − 100 × $650,000] × 0.00292 = $686,200 per year. The assessments are editable scenario assumptions, not appraisals, sale-price estimates, or observed averages. The 500-home scale is a proposed alternative for staff to test.
The cumulative figure assumes uniform completion from the beginning to the end of the selected period, with partial-year taxation approximated continuously: full annual revenue × years ÷ 2. It uses constant 2026 dollars, no appreciation, no discounting, and no construction-period loss of the old tax base. It is not an immediate annual windfall.
Compare three scales using the default values
| Net added homes | Existing homes replaced | Total new homes | Added annual city tax |
|---|---|---|---|
| 250 | 50 | 300 | $343,100 |
| 500 | 100 | 600 | $686,200 |
| 1,000 | 200 | 1,200 | $1,372,400 |
These are illustrations of tax arithmetic, not a determination that any number of homes fits on a particular site. A corridor redevelopment, vacant parcel, and infill replacement have different existing tax bases. Commercial space is excluded.
What if serving the additional homes costs more?
Compact growth can use infrastructure more efficiently, but services are not free. Test an assumed annual city operating cost per net additional home below. This is a sensitivity input, not a cost estimate. County schools and other county services require a separate analysis against county revenues.
Enter a cost to compare it with the current gross revenue scenario.
At the default assumptions, gross additional city property tax is $1,372.40 per net added home annually. Operating costs above that amount would exceed this one revenue source, before capital costs. This threshold is not the city’s actual marginal cost and excludes other possible revenues.
What a full city fiscal study still needs
Parcel-level existing assessments; the taxable value of different housing types and MPDUs; construction timing and demolition; state assessment phase-ins; exemptions, abatements, and any payment-in-lieu-of-tax agreement; city operating costs; utility and transportation capacity; capital financing; and the county’s school and service costs.
Public land or subsidized projects may have different tax treatment. Enterprise-zone eligibility or other incentives do not guarantee a particular tax credit on a particular property. Residential assessments cannot simply be substituted for an existing industrial or commercial tax base.
More homes can strengthen the budget and spread the cost of shared services across a larger tax base.
LET’S TALK ABOUT IT
What would this
mean for me?
Start with the questions on your mind.
Would I have to sell my home?
No. This proposal calls for willing owners to choose whether to redevelop. It does not call for eminent domain. Homeowners can keep their homes and continue living in them; rezoning creates options, not an obligation to sell.
Will everything change overnight?
Change happens one owner and one project at a time. Financing, design, approvals, and construction take years, and many owners will keep their homes just as they are. Allowing more homes across a meaningful area gives the neighborhood room to grow gradually as people choose to make a change.
What if the new homes are expensive?
New homes help even when their first residents pay market rates. Each additional home gives a household another option instead of competing for an existing one. Research finds that new supply can ease rent pressure, and moving chains open up homes elsewhere in the market. Rockville’s existing affordable-housing requirements provide another way to include below-market homes in qualifying developments.
NYU research review [10]Original moving-chain study [40]Rockville affordability tools [22]
Can this help older neighbors stay?
Yes. More smaller homes nearby can let seniors downsize without leaving friends, familiar places, and the community they helped build. Apartments with elevators and accessible layouts offer alternatives to maintaining a large house and yard. More housing choices mean more ways to stay in East Rockville as life changes.
Where will everyone park?
Current parking requirements continue to apply, and reductions require approval under the existing ordinance. Locating homes near Metro, shops, and services also gives residents more ways to get around without a car. Managing curb space for visitors, accessible parking, and loading can help make existing street space work better.
Will traffic get worse?
Location makes a difference. Research shows that compact neighborhoods near transit can support less driving per household than development farther from jobs and services. East Rockville already has Metro, MARC, and Amtrak. Pairing more homes with safer crossings and sidewalks makes better use of those connections.
Can our infrastructure handle more homes? What about the APFO?
Rezoning keeps Rockville’s infrastructure safeguards in place. Under the Adequate Public Facilities Ordinance (APFO), projects that require an adequate-facilities determination must show that public facilities can support them. Applicants must mitigate adverse impacts to meet the city’s standards; water and sewer adequacy is confirmed before a building permit. The neighborhood plan should identify school, utility, transportation, park, and emergency-service improvements alongside new homes. More residents also help fund the services we share.
Will my property value fall?
More housing does not automatically mean lower property values. An Urban Institute study in nearby Alexandria found a small positive association between affordable housing and surrounding home values. Additional redevelopment options can also add value to land, while more neighbors help support the shops and services that make a neighborhood desirable.
What happens to the neighborhood’s character?
Our neighbors, parks, porches, and everyday connections are part of that character. More housing choices can help people stay. Keeping detached-home zoning can still mean teardowns for large McMansions. This proposal puts larger buildings near the station and more modest homes on residential blocks, with existing protections still applying.
More questions: safety, green space, and neighborhood benefits
Do apartments bring crime?
The evidence does not support treating apartments as an automatic source of crime. Research on Low-Income Housing Tax Credit developments found crime reductions in low-income neighborhoods. Good lighting, maintenance, and responsive management are practical ways to support safety as a neighborhood grows.
Is some density already here inside detached homes?
Some households already share detached homes: an ERCA survey respondent described several households living in individual houses. Giving people more separate homes offers an alternative when sharing is driven by a lack of affordable choices. More front doors can meet needs that already exist in the neighborhood.
How does this help the climate?
Homes near trains and shops make it easier to drive less and reduce pressure to build farther out on undeveloped land. Smaller homes and shared walls also use energy more efficiently. Allowing compact homes here puts housing and climate action in the same place.
EPA: land use & travel [17]EPA: homes, transit & energy [35]Housing & climate [33]
What about trees and green space?
The proposal keeps public parks and existing tree and stormwater requirements in place. Compact homes within an established neighborhood can also reduce pressure to develop forests and open land farther out. Growing near our trains lets more people share the parks and green spaces we already value.
Who benefits besides builders?
Current and future neighbors gain more housing choices, opportunities to downsize nearby, and a stronger customer base for local shops. More homes can help our grown children find a place of their own and help longtime residents stay connected to the neighborhood.
What if people still need a car?
People do not have to give up their cars to benefit. Living near trains, shops, and services makes it possible to replace some car trips with walking or transit—and can give households more flexibility about how many cars they need. Every convenient alternative expands residents’ choices.
Why not put all the housing in Town Center?
Town Center should grow too. Both sides of the station are good places for more homes. A wider range of suitable sites and housing types gives the city more opportunities than relying on a few large projects.
Do current residents get a say?
Yes. The new neighborhood plan gives residents a direct opportunity to shape East Rockville’s future. ERCA’s survey already found substantial support among respondents for options that include missing-middle housing. Share the homes, services, and walking connections you want the city to make possible.
WHY I SUPPORT THIS
A case backed
by research.
The short version is here. The sources are one click away.
More homes can ease competition for the homes we already have.
Research supports adding supply alongside help for households who need affordable homes now. Allowing more homes near our trains is a practical step we can take locally.
NYU research review [10]Minneapolis Fed: moving chains [12]
Many neighbors already support more choices.
In ERCA’s 2024 survey, roughly 64% of respondents chose options including missing-middle homes within ¼ mile of Metro, and roughly 60% did so in the outer walking area.
ERCA reported 114 valid responses and 45 written comments in its 2024 neighborhood survey.

| Selected option | Within ¼ mile | Over ¼ to under ½ mile |
|---|---|---|
| Keep the 2040 plan’s proposed limits | 36.2% | 40.5% |
| Add missing middle: duplexes, triplexes, or rowhomes | 19.0% | 31.0% |
| Also allow small apartment buildings | 19.0% | 19.8% |
| Also allow large apartment / mixed-use buildings | 25.8% | 8.6% |
Source: report pages 2–5. The roughly 64% and 60% figures combine the last three options, which all include missing middle; the table shows the distinct levels of support for each housing option.
The practical takeaway: make missing-middle housing a central part of East Rockville’s next chapter.

Tell the city you support more housing choices in East Rockville.
Ask for more homes near Metro, modest infill on suitable neighborhood blocks, and practical improvements to streets and services.
We can welcome more neighbors while giving the people already here more ways to stay.
