1.3 What Counts as Home Improvement

The Statutory Definition (Bus. Reg. §8-101)

Everything in Maryland home improvement regulation flows from one definition. Under Maryland Code, Business Regulation Article, §8-101, home improvement means the addition to or alteration, conversion, improvement, modernization, remodeling, repair, or replacement of a building or part of a building that is used or designed to be used as a residence or a structure adjacent to that residence.

Notice two features of that definition. First, the verb list is deliberately broad — nearly any verb a contractor might use to describe changing an existing home fits inside it. Second, the object is an existing residential building. Work that creates a residence where none existed is not home improvement; work that changes one that already exists almost always is.

Adjacent Structures Are Included

The definition expressly reaches beyond the four walls of the house. The statute's own examples of adjacent structures include:

• Driveways
• Fences
• Garages
• Decks
• Porches
• Piers (but see the marine-contractor note below)
• Swimming pools
• Landscaping

The statute also names a fall-out shelter in the same list, and §8-101(g)(2) separately sweeps in a shore erosion control project for residential property, the connection, installation, or replacement of a dishwasher, disposal, or icemaker refrigerator to existing exposed household plumbing lines, the installation of an awning, fire alarm, or storm window, and work done on individual condominium units.

This is one of the exam's favorite testing grounds. Candidates intuitively think of home improvement as kitchens and bathrooms and forget that pouring a driveway, building a detached garage, installing an in-ground pool, or even landscaping a residential lot all require an MHIC license when done for compensation.

One live caveat on piers. Piers remain in the §8-101 list, but since January 1, 2017 the Maryland Marine Contractors Licensing Board — administered by the Maryland Department of the Environment — licenses marine contractor services, and under §8-301(d)(6) the MHIC no longer has jurisdiction over marine contracting, including pier installation and shore erosion control projects. A marine contractor still needs an MHIC license for any home improvement work outside the marine scope.

Condominiums — A Built-In Trap

Work on an individual condominium unit is home improvement. Work on the commonly owned areas of a condominium — the lobby, hallways, roof over the whole building, shared recreational facilities — is excluded. The logic is that the statute protects individual residential owners, and a condo association acting for the common elements is a different kind of client. Expect a question that swaps unit for common area to see if you notice.

The Exclusions — Memorize This List

That is the complete §8-101(g)(3) list — six exclusions, not three. The four-or-more-units rule is frequently tested with edge numbers: a three-unit building is inside the definition; a four-unit building is outside it. The line is at four, not above four. The appliance pair is the other favorite: connecting a dishwasher to existing exposed plumbing is home improvement, but a connection that requires altering the plumbing lines is not.

When the License Obligation Attaches (§8-301)

Under §8-301, a person must hold an MHIC license before the person performs or offers or agrees to perform home improvement work for a homeowner, a tenant, or another person. Three points matter here:

1. The trigger is earlier than you think. You do not need to swing a hammer to violate the law. Signing a contract, signing an agreement, or even offering to do the work without a license is itself a violation. Advertising home improvement services you are not licensed to perform falls in the same zone.
2. The client list is broad. The duty applies to work for a homeowner, a tenant, or another person — you cannot avoid the license requirement by contracting with the tenant rather than the property owner.
3. Offers count. Exam questions often describe a contractor who merely signed a contract but had not started work when the licensing issue arose. The answer turns on the phrase offers or agrees to perform, not on whether work began.

Exam Scenarios to Practice

• Pool installer. A company installs in-ground pools behind existing homes. Home improvement? Yes — swimming pools are enumerated adjacent structures.
• New-build painter. A painter contracts to paint a house under construction that has never been occupied. Not home improvement — it is new construction, excluded from the definition.
• Condo lobby renovation. A contractor renovates the common lobby of a condominium for the association. Not home improvement — commonly owned areas are excluded.
• Duplex versus quadplex. Remodeling a duplex or triplex is home improvement; remodeling a building with four units is not, because the exclusion bites at four or more single-family units.
• Eager bidder. An unlicensed contractor signs a remodeling agreement on Monday and plans to apply for a license on Friday. A violation already occurred on Monday, because agreeing to perform the work requires a license under §8-301.

When a question asks whether a license was required, run the checklist in order: Is the building an existing residence or adjacent structure (and not 4+ units, not new construction, not condo common areas)? If yes, did the person perform, offer, or agree to perform the work for someone? If yes, an MHIC license was required.

Reading the Definition Like an Examiner

Exam writers exploit three phrases in §8-101 that candidates skim past.

Used or designed to be used as a residence. The test is the building's residential character, not who owns it or whether anyone currently sleeps there. A vacant house, a house under renovation, and a rental property all remain residences. Conversely, work on a purely commercial building is outside the definition no matter how residential the work feels — drywall is drywall, but drywall in an office suite is not home improvement.

Or part of a building. You do not need to touch the whole structure. Replacing a single window, repairing one section of roof, or remodeling one bathroom qualifies. This forecloses the defense that a job was too small to need a license — the statute contains no de minimis exception in its definition, and minor repair jobs for homeowners are licensed activity just as much as full additions are.

Homeowner, tenant, or another person (§8-301). Candidates sometimes assume the license protects only owner-occupants. It does not. If your client is a tenant improving the rental, a landlord, a property manager, or any other person contracting for covered work on a qualifying residence, the license obligation attaches the same way. The statute's pair of protections — a broad definition of the work and a broad list of protected clients — is deliberately hard to route around.

Keep the boundary cases anchored to the three exclusions and you will handle nearly every variant: new construction goes to the Home Builder Registration Unit, common condominium elements fall outside the definition entirely, and a residential building hits the exclusion the moment it contains a fourth single-family unit. Everything else on an existing residence — indoors or out, big or small, for an owner or a tenant — is home improvement, and performing it, offering it, or agreeing to it without a license violates §8-301.
