Laurel ADU Rules 2026: Ordinance 2057 Adopted & City Zoning

Laurel adopted Ordinance No. 2057 / Text Amendment No. 270 on September 28, 2026, and it took effect that day. Laurel administers its own zoning and development code, so homeowners inside City limits should not automatically use Prince George’s County ADU rules. The signed ordinance amends the Unified Land Development Code to enable and regulate ADUs. Planning Commission review preceded final Mayor and City Council action. The signed enactment was verified October 10, 2026; parcel eligibility and permits still require City review.

The safest way to plan right now is to separate what Laurel has already enacted from which requirements apply to your parcel. The City is its own zoning authority, and Ordinance 2057 is now adopted and effective. Adoption does not approve every project: confirm zoning, the permitted ADU form, site conditions and the City’s application requirements.

Enactment verified: October 10, 2026, against the signed Ordinance 2057. This page is informational; it is not a parcel-specific approval or legal advice. Verify current requirements with the City of Laurel Department of Economic and Community Development before paying for plans, permits, or construction.

Laurel ADU status at a glance

Laurel controls its own zoning

The City of Laurel Department of Economic and Community Development performs zoning compliance, subdivision review, development review and implementation of the City Master Plan. The City maintains its own residential, commercial, office, industrial and planned-development zoning districts under the Unified Land Development Code.

This matters because a Laurel mailing address can easily lead a homeowner to the Prince George’s County ADU page. For a property actually inside City limits, begin with Laurel’s zoning staff and City code instead. Use the Prince George’s County guide only when County zoning controls the parcel.

What Ordinance 2057 changed

The signed Ordinance No. 2057 / Text Amendment No. 270 amended several sections of Chapter 20 of the Unified Land Development Code, including the definitions section, residential-use table, accessory-structure bulk regulations and the rule governing buildings permitted on a lot. The stated purpose is to enable and regulate accessory dwelling units.

The enacted framework requires the resident owner to occupy the main home or ADU (§20-6.14(h)), caps ADU size at 75% of the primary single-family dwelling (§20-6.29(d)), and requires no additional parking for a duly approved ADU (§20-16.2(a)). The detached-unit minimum is 200 square feet on the first or ground level. Check zoning eligibility and site constraints before treating the size limit as buildable area. See the signed ordinance, pages 3–5. For a detached unit, check the public-sewer frontage requirement in Section 20-50.3(b) before paying for plans: the property must abut a street or public right-of-way containing a public sanitary sewer, and an application to WSSC or the applicable authority is required.

September 28, 2026 adoption and effective date

The signed ordinance records passage and mayoral approval on September 28, 2026. Its final clause states that it takes effect on the day of passage.

Homeowners should now confirm how the enacted requirements apply to their zoning district, proposed unit and site.

Does Laurel use a “zoning certificate” for an ADU?

Searchers often use the phrase “Laurel zoning certificate”, but the City’s published permit system uses zoning review plus a Use and Occupancy Permit rather than presenting a homeowner ADU approval as a permit called a “zoning certificate.” The City says a Use and Occupancy Permit is required to legally inhabit and use property, including new residential construction and qualifying changes of use or occupancy.

For an ADU, ask the City to identify the zoning determination required under the current ordinance, the building permits needed for the construction work, and when the Use and Occupancy Permit is issued. Do not assume a Prince George’s County zoning certificate or County approval substitutes for Laurel’s municipal process.

What permits are needed under Ordinance 2057?

Laurel’s current development system still requires homeowners to use the City’s existing zoning and permit process. The City says residential and commercial uses must comply with the zoning district’s allowable-use rules, and a use and occupancy permit is required for new residential construction and other qualifying changes of use or occupancy.

The City also administers building permits under its adopted building codes. ADU approval still requires the applicable zoning and permit process; enactment alone does not authorize construction or occupancy. Ask City staff to identify the currently available approval path for the specific property and ADU form before paying for final drawings.

How Maryland HB 1466 affects Laurel

Maryland’s HB 1466 became effective October 1, 2025 and requires local governments to adopt local laws authorizing ADUs by October 1, 2026. The state definition covers a secondary unit on the same property as a primary single-family detached dwelling and allows the ADU to be up to 75% of the size of the primary dwelling.

Maryland also says local ADU laws may not impose side and rear setbacks greater than those already applicable to accessory structures. If a jurisdiction requires additional off-street ADU parking, it must first complete a parking study and provide a waiver process.

Ordinance 2057 expressly responds to Maryland’s ADU legislation. Use the enacted City text alongside applicable State requirements and obtain a parcel-specific determination before construction.

What Laurel homeowners should do now

1. Confirm that the property is inside Laurel City limits. Do not rely on the mailing address alone.
2. Check the zoning district with Laurel. The City maintains its own zoning map and use tables.
3. Ask which zoning approval and permit path applies under the effective Ordinance 2057.
4. Verify the enacted size and site standards before final design.
5. Use the signed September 28 ordinance as the enacted source. The Planning Commission recommendation was an earlier step, not the final enactment.
6. Check detached-unit sewer eligibility early. Section 20-50.3(b) imposes a public-sewer frontage and application condition for detached ADUs.
7. Separate ordinance effect from project approval. Ordinance 2057 took effect September 28, 2026; your project still needs the applicable approvals.
8. Re-check permits before spending. Confirm building, use-and-occupancy and any property-specific requirements with City staff.

YOUR NEXT PRACTICAL STEP

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.

1. Find Who Reviews My Property.
2. Obtain your parcel identifier, survey, floor plans and utility records.
3. Ask the reviewing office which current rules, supporting documents and approvals apply.
4. Continue to your planning workspace.
