Takoma Park does not have a separate city ADU zoning code. The City states that zoning authority lies with Montgomery County, so homeowners must follow Montgomery County’s ADU zoning and building-permit process. Takoma Park then adds its own municipal review layers, including a Municipality Letter, possible tree/stormwater/right-of-way permits, historic-district review, and City rental licensing if the ADU will be rented.
The key planning mistake to avoid is treating Takoma Park like Rockville or Gaithersburg. Those cities administer their own zoning. Takoma Park does not: Montgomery County’s zoning ordinance is the primary zoning standard, and Montgomery County Department of Permitting Services issues the building permits. The City’s role is layered on top through municipal and rental-housing requirements.

Who controls zoning in Takoma Park?
The City of Takoma Park’s Development Review page explicitly states that zoning authority lies with the Montgomery County Planning Department. The City also says the Montgomery County Zoning Ordinance is the primary standard used to evaluate development and that required construction, renovation and demolition permits are issued by Montgomery County DPS.
That means homeowners should not use a separate Takoma Park size, setback or parking number unless the City adopts a local overlay or other rule that actually changes the County standard. For the current numeric ADU rules and the status of ZTA 26-06, use our Montgomery County ADU Rules 2026 guide.
Which ADU rules apply?
Current ADU zoning in Takoma Park follows the Montgomery County framework. That framework is itself in transition in 2026, so homeowners should verify the current County rule before designing to a specific maximum size, parking exemption or setback assumption. We keep the live legislative status on the Montgomery County page rather than duplicating changing numbers here.
This is deliberate: a separate Takoma Park page is useful because of the City’s permit and licensing layers, but duplicating the entire Montgomery County zoning article would create unnecessary overlap and a higher risk that one page becomes outdated before the other.
You need a Takoma Park Municipality Letter before County permitting
Takoma Park says that renovation, building and outdoor projects requiring a Montgomery County DPS permit first require a Municipality Letter from the City. The letter itself is not a permit and has no fee, but it identifies additional Takoma Park requirements that may apply to the project.
For an ADU, this matters because the City may need to review tree impacts, stormwater management or work affecting the City right-of-way before or alongside the County permit process.
Historic-district properties need an extra approval layer
If the property is within the Takoma Park historic district, exterior changes may require a Historic Area Work Permit (HAWP). The City explains that these applications are reviewed by the Montgomery County Historic Preservation Commission and must be approved before the related construction permit can be issued.
This can materially affect detached ADUs, additions, garage conversions, exterior entrances and other visible alterations. Homeowners in the historic district should treat historic review as an early feasibility question, not an afterthought once plans are complete.
Tree, stormwater and right-of-way rules can affect the site plan
Takoma Park’s Municipality Letter guidance says construction within 50 feet of certain urban forest trees may trigger a Tree Impact Assessment and Tree Protection Plan, and tree removal requires a separate application. Stormwater review can also apply depending on project type and land disturbance.
City permits may also be required for a driveway apron, dumpster or storage container in the right-of-way, a fence in the right-of-way, or other work affecting City-owned space. These requirements do not replace County zoning; they sit on top of it.
If you rent the ADU, Takoma Park rental licensing applies
Takoma Park requires all rental housing in the City to be licensed. The City’s 2026 rental-housing page lists a license fee of $135 per unit and requires landlord certification, applicable lead-poisoning-prevention documentation and a property inspection before a license is issued.
The City notes that inspections are conducted by Montgomery County DHCA even though the rental license itself is issued by Takoma Park. This is another example of the split local/County process homeowners need to understand.
What Takoma Park homeowners should do before spending money
- Confirm the property is inside Takoma Park. Use the exact address, not just a mailing label.
- Read the current Montgomery County ADU rules. County zoning controls the core ADU standards.
- Request the Takoma Park Municipality Letter. Do this before the County permit process that requires it.
- Check historic-district status. A HAWP can affect exterior design and timing.
- Check tree and stormwater impacts. A detached ADU or addition can trigger City review even when County zoning is satisfied.
- Plan for rental licensing if the ADU will be rented. City licensing is separate from zoning approval.
- Re-check Montgomery County’s 2026 legislative status before final design. ZTA 26-06 may change the controlling County standards.
