Summary

Most Montgomery County HOAs require homeowners to submit exterior modification requests to an architectural review committee (ARC) before making changes. This applies to paint colors, additions, fencing, landscaping, solar panels, and other visible modifications. Maryland law limits HOA authority over solar and EV charging installations.

These county ordinances apply to unincorporated areas of Montgomery County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Section 11B-101. (a) In this title the following words have the meanings indicated, unless the context requires otherwise. (a-1) "Accessory dwelling unit" has the meaning stated in Section 4-501 of the Land Use Article. (b) "Common areas" means property which is owned or leased by a homeowners association. (c) "Declarant" means any person who subjects property to a declaration. (d) (1) "Declaration" means an instrument, however denominated, recorded among the land records of the county in which the property of the declarant is located, that creates the authority for a homeowners association to impose on lots, or on the owners or occupants of lots, or on another homeowners association, condominium, or cooperative housing corporation any mandatory fee in connection with the provision of services or otherwise for the benefit of some or all of the lots, the owners or occupants of lots, or the common areas. (2) "Declaration" includes any amendment or supplement to the instruments described in paragraph (1) of this subsection. (h) "Governing body" means the homeowners association, board of directors, or other entity established to govern the development. (i) (1) "Homeowners association" means a person having the authority to enforce the provisions of a declaration. (2) "Homeowners association" includes an incorporated or unincorporated association. (l) "Recorded covenants and restrictions" means any instrument of writing which is recorded in the land records of the jurisdiction within which a lot is located, and which instrument governs or otherwise legally restricts the use of such lot.

Full Breakdown

HOA-governed communities in Montgomery County typically require prior approval from an Architectural Review Committee (ARC) or Design Review Board before any exterior modification. Common items requiring ARC approval include paint color changes, roof replacements, fence installation, deck construction, landscaping changes, shed placement, satellite dishes, and exterior lighting. Many communities in Clarksburg, Germantown, North Potomac, and Bethesda have detailed architectural guidelines specifying approved colors, materials, and styles. The review process typically requires a written application with plans, and the ARC must respond within a timeframe specified in the governing documents, often 30 to 45 days.

Maryland law provides some protections against overly restrictive HOA rules. 1, HOAs cannot prohibit or unreasonably restrict solar energy collection systems. The Maryland Condominium Act (Real Property Article 11) provides similar protections for condominiums. HOAs also cannot prohibit the installation of EV charging stations in accordance with Maryland law. If an ARC denies a request, the homeowner can typically appeal to the full board of directors.

Violations & Fines

Making exterior changes without ARC approval can result in violation notices, fines (often $50 to $200 per day), and requirements to restore the property to its original condition at the homeowners expense. The HOA may place a lien on the property for unpaid fines.

Frequently Asked Questions

Can my HOA block me from installing solar panels in Montgomery County?
No. Maryland Real Property Article 2-119.1 prohibits HOAs from banning or unreasonably restricting solar energy collection systems. The HOA may regulate placement but cannot prohibit installation.
What happens if I make exterior changes without HOA approval?
The HOA can issue violation notices, impose daily fines, and require you to remove the unapproved changes at your own expense. Unpaid fines can become a lien on your property.
