Prince George’s County ADU Rules: CB-074-2026 Transition Guide

Prince George’s County is in an active ADU transition. The County Council is considering CB-074-2026, a zoning ordinance intended to add ADU definitions, designate where ADUs may be allowed, and establish local regulations consistent with Maryland’s statewide ADU law.

The important point for homeowners is that the county’s final 2026 ADU rules are not yet verified as enacted. This guide therefore separates the official legislative timeline from proposed provisions and avoids presenting draft criteria as settled law. For the statewide comparison, use our Maryland County ADU Rules Tracker.

This sequence matters because a committee discussion, amendment vote, or favorable recommendation is not the same as final enactment. Until the Council record shows final adoption and an effective date, this site will continue to label Prince George’s County Transition.

What CB-074-2026 is intended to do

The official bill record describes CB-074-2026 as an ordinance concerning accessory dwelling units. Its stated purpose is to add definitions, designate areas for ADUs consistent with Maryland law, set regulations for permitted ADUs, address prospective application of the new provisions, and include a severability clause.

The official record identifies proposed changes in several zoning-code sections, including Sections 27-2201, 27-2500, 27-4403, 27-5201, and 27-5203. The county also published supporting materials including a bill summary, Planning Board recommendation, technical staff report, testimony, and a policy/fiscal analysis.

Official bill record: Prince George’s County — CB-074-2026.

A second ADU bill now matters: CB-092-2026

Prince George’s County introduced a separate companion bill, CB-092-2026, on September 1, 2026. This is important because CB-074-2026 is primarily the zoning vehicle, while CB-092 addresses several non-zoning implementation issues.

The official CB-092 title specifically covers proposed ADU requirements, a prohibition on short-term rental of ADUs, rental requirements, Woodland and Wildlife Habitat Ordinance treatment, Tree Canopy Coverage Ordinance treatment, impervious-surface requirements, and individual sewage-disposal-system requirements.

The Council record states that CB-092 was created because Council members and staff were already working on the ADU zoning bill but identified numerous non-zoning issues that needed to be placed elsewhere in the County Code. As of this review, CB-092 is listed as Presentation and referral, not enacted law.

What homeowners should not treat as final yet

At this stage, homeowners should not rely on draft summaries for a final ADU size cap, approval route, parking rule, owner-occupancy rule, setback standard, rental restriction, or effective date unless that provision appears in the final enacted ordinance and current county implementation guidance.

This is especially important because the official legislative history already shows that both technical staff and the Planning Board supported the proposal with amendments. The final text can therefore differ materially from the original draft.

Planning takeaway: use CB-074-2026 to understand the direction of travel, but do not purchase plans, commit to a prefab unit, or size a project around a proposed local rule until the County Council adopts final text and the county confirms how it will be administered.

How Maryland’s statewide law fits into the transition

Maryland HB 1466 became effective October 1, 2025 and requires counties and municipalities with planning and zoning authority to adopt a local law authorizing ADUs by October 1, 2026. The state definition allows an ADU up to 75% of the size of the primary single-family detached dwelling, while Maryland Department of Planning recommends measuring the primary dwelling using finished living area above grade unless the local ordinance or implementation guidance establishes a different lawful method.

That statewide framework does not tell a Prince George’s County homeowner exactly what permit path, dimensional details, parking treatment, or local administration will apply after CB-074-2026. Those details need to come from the final local ordinance and county implementation materials.

For the statewide baseline, read our Maryland ADU Guide 2026.

What Prince George’s County homeowners should do now

Confirm your exact jurisdiction. A municipality may have its own zoning authority or implementation details.
Use the state framework only as the baseline. Do not assume Maryland’s statewide rules answer every local permitting question.
Track CB-074-2026 in the official Council system. Look for a final action, adopted text, chapter number, and effective date.
Do not design around draft local numbers. Proposed size, parking, setback, occupancy, or rental provisions can change during committee and Council review.
Re-check immediately before spending. Verify the current ordinance and permit instructions before buying plans, signing a prefab contract, or paying a contractor deposit.
Use our tracker for status changes. The Maryland County ADU Rules Tracker will continue to distinguish proposed and enacted rules.
