Indian Head MD ADU Rules 2026: Draft 06-01-26, Size, Garage Units & Rentals

Last researched: September 18, 2026. Indian Head is actively updating its ADU rules through Draft Ordinance 06-01-26 — Accessory Dwelling Units. The Town already has detailed legacy accessory-apartment standards, so homeowners need to distinguish the currently published zoning code from the proposed 2026 replacement/update.

Quick homeowner answer: Indian Head’s published zoning code currently allows a primary residence with an accessory apartment as a permitted use in several districts, subject to supplemental conditions. Those legacy conditions include owner occupancy, one accessory apartment per single-family dwelling, and different size rules for an apartment inside the main house versus one in an accessory building. Because the Town now publishes a dedicated 2026 draft ADU ordinance, confirm which standards are legally effective before buying plans.

1. Indian Head is not simply Charles County zoning

Indian Head is an incorporated municipality that provides its own planning, zoning, permitting, water and wastewater services. For an in-Town property, start with the Town Planning & Zoning Administrator. If your parcel is outside Town limits, use our Charles County ADU Rules guide.

2. Indian Head already has a detailed accessory-apartment framework

The published zoning use table lists a Primary Residence with Accessory Apartment as permitted in R-1, R-2, TCMX and Public Institute, subject to supplemental conditions. That is important because Indian Head is not starting from zero in 2026.

The existing conditions are also much more specific than a generic statewide ADU description. They distinguish an apartment inside the principal dwelling from one located in an accessory building.

3. Legacy internal-apartment size: 300 sq ft minimum and 30% maximum

For an accessory apartment inside the principal dwelling, Indian Head’s published legacy rule sets a 300-square-foot minimum and says the apartment may not exceed 30% of the gross floor area of the dwelling.

That creates an obvious 2026 verification issue under Maryland’s newer ADU framework. For a 1,800-sq-ft house, 30% is only 540 sq ft, while 75% is 1,350 sq ft. Do not finalize a floor plan around the legacy 30% cap without asking which standard the Town currently administers.

4. Indian Head’s legacy rule also recognizes accessory-building apartments

The published rule says an accessory apartment may be located either in the principal dwelling or in an accessory building. For an accessory-building apartment, the legacy rule sets a 300-sq-ft minimum, limits the apartment to no more than two bedrooms, and says it may not occupy more than 50% of the main structure.

This makes Indian Head materially different from municipalities whose older code only contemplated an internal apartment. It also means a garage or other accessory-building concept deserves parcel-specific review rather than a generic “detached ADU” assumption.

5. Owner occupancy is part of the published legacy framework

Indian Head’s published accessory-apartment conditions require the owner of the lot to occupy at least one of the dwelling units on the premises. If your financial model assumes both the primary home and ADU will be rented while you live elsewhere, do not assume the legacy code allows it.

Because Draft Ordinance 06-01-26 is specifically addressing ADUs in 2026, verify whether the final ordinance retains or changes this condition.

6. One accessory apartment per single-family dwelling under the legacy rule

The published zoning conditions allow no more than one accessory apartment per existing single-family dwelling. Do not plan a second ADU or a separate “junior ADU” concept without a specific Town determination under the final 2026 framework.

7. Exterior appearance matters for an internal apartment

Where the accessory apartment is inside the principal dwelling, the published legacy rule says the entry and design should preserve the appearance of a single-family residence to the extent reasonably feasible and prohibits adding an external entrance facing a road or street.

That can affect an internal conversion floor plan. Ask whether the final 2026 ordinance retains this design requirement before locating a new entrance.

8. Draft Ordinance 06-01-26 is the document to watch

Indian Head’s official ordinance page currently lists DRAFT Ordinance 06-01-26 — Accessory Dwelling Units. Because it is explicitly labeled draft, this guide does not present proposed provisions as enacted law.

Before filing, ask the Town whether 06-01-26 has been enacted, revised or replaced and request the final signed ordinance. This is especially important for size, detached-unit treatment, parking and any owner-occupancy changes.

9. Water and sewer are Town-level feasibility questions

Indian Head operates Town-owned water and wastewater facilities. An additional dwelling can affect fixture load, capacity, metering, connection and fee questions. The legacy accessory-apartment standards also address water/sewer review before building-permit issuance.

Ask whether the ADU can share existing service, whether upgrades or a separate meter are required, and what current utility charges apply before finalizing plumbing design.

10. Renting the ADU is a separate licensing question

Indian Head publishes both a Rental License Application and Rental Inspection Information. That means zoning/building approval and authorization to operate a rental should be treated as separate steps.

If rental income is part of your project budget, confirm the current license, inspection and occupancy requirements before relying on that income.

Does Indian Head already allow accessory apartments?

Yes. The published zoning code lists a primary residence with an accessory apartment as a permitted use in several districts, subject to supplemental conditions.

Are Indian Head ADU rules the same as Charles County?

How large can an internal accessory apartment be under the published legacy rule?

The legacy rule sets a 300-sq-ft minimum and a maximum of 30% of the principal dwelling’s gross floor area. Because Indian Head has a draft 2026 ADU ordinance, verify the current standard before designing.

Can I put an accessory apartment in a garage or accessory building?

The published legacy rule expressly allows an accessory apartment in an accessory building. It sets a 300-sq-ft minimum, no more than two bedrooms, and a maximum of 50% of the main structure. Confirm how the final 2026 ordinance treats this configuration.

Do I have to live on the property?

The published legacy rule requires the owner to occupy at least one of the dwelling units on the premises. Verify whether the final 2026 ADU ordinance changes that condition.

Can I have two ADUs?

The published legacy rule allows no more than one accessory apartment per existing single-family dwelling. Do not plan a second unit without a Town determination under the current framework.

Has Draft Ordinance 06-01-26 become law?

The Town’s ordinance page reviewed for this guide still labels 06-01-26 as a draft Accessory Dwelling Units ordinance. Ask Town Hall for the final enacted or revised version before relying on proposed provisions.
