Quick answer: Bowie does not operate as a fully separate ADU zoning jurisdiction. The City says Prince George’s County and the Maryland-National Capital Park and Planning Commission generally control zoning and development review, while Bowie’s role is mostly advisory with limited delegated authority over certain variances and departures. For most construction work, homeowners also need both a Prince George’s County permit and a City of Bowie permit.
That makes Bowie different from a city with its own complete zoning code: the most important ADU rules come from Prince George’s County, but Bowie can still add another permit and, if the unit is rented, a city rental-license step.
Are ADUs currently allowed in Bowie?
As of September 18, 2026, Prince George’s County is actively moving an ADU implementation package through the legislative process. The zoning measure is CB-074-2026; a separate bill, CB-092-2026, addresses non-zoning issues including rentals, short-term rentals, impervious surface and sewage-disposal requirements. The County has also introduced CR-095-2026 to address a potential timing gap around Maryland’s October 1, 2026 deadline. These measures should be treated as pending until final action is complete.
Prince George’s County created an Accessory Dwelling Units Task Force to develop implementation ideas, and that task force met repeatedly through 2026. The County’s own materials describe the task force as part of the work needed to translate the new state requirements into local rules.
Planning takeaway: Bowie homeowners should not assume that an ADU shown as feasible under Maryland’s new statewide framework is already permit-ready under today’s Prince George’s County zoning rules. Verify the current county ordinance before paying for final plans.
Who controls zoning in Bowie?
The City of Bowie states that it does not have general planning and zoning authority. Development review in Prince George’s County is generally handled by the Maryland-National Capital Park and Planning Commission and the Prince George’s County Council.
Bowie still participates in the process. The City reviews and comments on development proposals, and Prince George’s County has delegated certain powers to Bowie, including review of some variances and departures. Bowie’s Planning Director and Advisory Planning Board can therefore become relevant when a project needs relief from a county zoning requirement.

Bowie adds a second building-permit layer
Bowie’s permit process is one of the strongest reasons the city deserves its own ADU page.
The City’s Building & Sign Permits guidance says property owners are required to obtain permits from both Prince George’s County and the City of Bowie for most improvements or alterations. Examples listed by the City include additions, garage conversions, basement remodeling and new homes — all project types that can overlap with an ADU.
The normal sequence is:
- Confirm that the proposed ADU is allowed under the current Prince George’s County zoning rules.
- Obtain the required Prince George’s County approvals and building permit.
- Submit the County permit, approved plans and site plan to the City of Bowie for the City permit.
- Complete any additional City review, including a variance if the project requires one.
- Complete construction and inspections under the applicable County and City requirements.
Bowie’s own building-permit FAQ says the County has exclusive authority for construction-code approval and inspection under the Maryland Building Performance Standards, while the City permit is used to check compliance with Bowie City Code, covenants and related local requirements.
For the broader approval sequence, see our Maryland ADU permits-to-completion guide.
What about a garage conversion or detached backyard unit?
Garage conversions are specifically listed by Bowie among projects requiring permits from both the County and City. A detached backyard ADU can be even more complicated because local accessory-structure rules, setbacks, lot coverage and height can all interact with the County’s future ADU rules.
Do not assume the existing location of a garage automatically makes a residential conversion legal. Existing structures can still have nonconforming setbacks, use limitations or building-code issues that need to be resolved before occupancy.

Rental licensing is a separate Bowie requirement
If the ADU will be rented, Bowie adds another city-specific layer. The City’s Rental Housing Program says a City of Bowie rental license is required for rental situations including basement rentals, partial-home or in-law-suite rentals, short-term rentals, single-family homes, townhouses and condos.
The City currently lists an annual rental-license fee of $120 for houses and partial rentals, with a separate fee structure for short-term rentals. Because ADU rental rules can change as the County implements the new state law, confirm both zoning legality and licensing before advertising a unit.
See our Maryland ADU rental and short-term rental guide for the statewide planning context.
What if your Bowie ADU needs a variance?
Bowie has delegated authority over certain variances and departures from the Prince George’s County Zoning Ordinance. The City’s variance page says an appointment with the Planning Director and a referral from Prince George’s County are required before applying.
That can matter for an ADU when an existing lot or accessory structure cannot meet a dimensional requirement. However, Maryland’s statewide ADU law limits some local restrictions, so whether a variance is still required will depend on the final Prince George’s County implementation rules and the specific issue involved.
What is changing before October 1, 2026?
Maryland law requires local jurisdictions to authorize qualifying ADUs on land zoned for single-family residential use by October 1, 2026. Prince George’s County has been working through its ADU Task Force and Planning Department while its existing public guidance still describes ADUs as prohibited.
For Bowie homeowners, the important point is that the County — not Bowie alone — must resolve the core zoning framework that determines where and how ADUs can be approved. Bowie will still matter for its own building permit, local code review, delegated variance role and rental licensing.
Bowie ADU homeowner checklist
- Confirm your property is actually inside Bowie. Mailing addresses can be misleading.
- Check current Prince George’s County ADU status. Do not rely on an older county FAQ once the new ordinance is adopted.
- Confirm zoning and parcel constraints. Check setbacks, lot coverage, height, easements and utilities.
- Ask DPIE what County permits are required.
- After County approval, apply for the City of Bowie permit.
- Check whether a Bowie variance or other local approval is needed.
- If renting, verify the City rental-license requirement.
Bottom line
Bowie is a good example of why Maryland homeowners should not stop at a county-level ADU rule. Prince George’s County controls the core zoning and construction-code framework, but Bowie adds its own permit, delegated variance process and rental-license requirements.
Until Prince George’s County completes its 2026 ADU implementation, treat Bowie as a transition jurisdiction: the state deadline is approaching, but the existing County zoning guidance still does not provide a normal by-right ADU pathway.

What to do next
Start by finding the office that reviews your property. A mailing city or a county guide does not establish your parcel’s authority.
- Find Who Reviews My Property.
- Obtain your parcel identifier, survey, floor plans and utility records.
- Ask the reviewing office which current rules, supporting documents and approvals apply.
- Continue to your planning workspace.
