A home inspector reviews a checklist with buyers, covering foundation, roof, electrical, and other key areas to ensure the home’s condition is fully understood.
Home inspections are a critical step in Maryland real estate transactions. They help buyers identify issues and give sellers a chance to address problems before they derail a sale. Below, we dive into what buyers and sellers should expect, the types of inspections common in Maryland, state-specific requirements, negotiation tactics after an inspection, and current market trends. This Maryland-focused insight will prepare you for a smoother home buying or selling experience.
1. Inspection Basics for Buyers & Sellers
For Home Buyers: What to Expect & How to Prepare
Inspection Contingency & Timeline: In Maryland, most purchase contracts include a Property Inspections Addendum – an inspection contingency giving the buyer a set time (often 7–14 days after contract acceptance) to perform inspections. Schedule a licensed home inspector promptly to meet deadlines, since missing the deadline means you buy “as is” with no further repairs.
During the Inspection: A standard home inspection takes about 2–3 hours. Buyers are encouraged to attend and observe. Inspectors will visually examine the home’s structure, systems, and components – from the foundation and roof to electrical panels and plumbing. A good inspector also educates buyers on home systems and maintenance (e.g. pointing out HVAC filters or estimating remaining life of the water heater). Expect a detailed written report with findings and photos.
Common Findings: Very few inspections are “clean” with zero issues. Typical Maryland home inspection findings include minor and major items: for example, grading and drainage problems causing basement leaks, roofing issues like missing flashing, outdated or unsafe electrical wiring, minor plumbing leaks, or older HVAC systems. Older Maryland homes may have deferred maintenance (peeling paint, worn HVAC, etc.) that show up in inspections. Buyers should be ready to see a list of issues – this is normal. Focus on significant defects (structural problems, safety hazards, water intrusion, mold, etc.) and don’t panic over minor or cosmetic items.
Keep Perspective: Use the inspection report as a tool for decision-making. Remember that an inspection is not a pass/fail test – it’s a snapshot of condition. No house is perfect, especially in Maryland’s older housing stock. The goal is to identify any major defects or safety issues. Small maintenance items (a dripping faucet or nail pops in drywall) can be addressed later by the buyer. Major issues that pose health/safety risks or affect habitability are the ones to negotiate with the seller. In short, don’t nit-pick every line item – focus on what truly matters for your safety and budget.
For Home Sellers: Preparing Before Listing & Before Buyer Inspections
Pre-Listing Prep to Avoid Surprises: It’s wise for Maryland sellers to fix known issues before listing the home. Address simple repairs like leaky faucets, missing shingles, or peeling paint to prevent them from showing up on the buyer’s inspection report. Consider a pre-listing inspection – some sellers hire their own inspector to identify problems in advance. Taking care of defects early means fewer last-minute surprises that could scare off buyers. Deals are far less likely to fall through when sellers have already addressed or disclosed known problems ahead of time
.
Disclosure Obligations: Maryland law requires sellers to either provide a Property Condition Disclosure or choose an “As-Is” disclaimer for most residential sales. Even with a disclaimer (selling as is), you must disclose any latent defects that pose a health or safety risk – for example, known structural issues, termite damage, high radon levels, or a failing septic system. It’s better to be transparent; hiding issues can lead to lawsuits later. In fact, if you’re questioning “Should I disclose this?”, the answer is almost always yes. Buyers appreciate honesty, and disclosing known problems builds trust and protects you legally.
During the Buyer’s Inspection: When a buyer schedules their inspection, plan to be away from the home during the inspection timeframe. Maryland buyers pay for their inspections, and the findings “belong to them,” so give the inspector and buyers space to evaluate the house. Hovering sellers can make buyers nervous. You’ll get to see the results soon enough – if the buyers request repairs, they will provide the relevant pages of the report to justify their asks. It’s best to remain hands-off and patient at this stage.
Common Issues in MD Homes: Be aware of the typical trouble spots inspectors find in Maryland so you can pre-empt them. Some examples: water and moisture issues are common (damp crawl spaces, basement seepage) – ensure gutters, grading, and sump pumps are functioning to prevent bad reports. Roof and attic problems (missing flashing, past leaks, poor ventilation) often arise – address known roof leaks or shingle damage. Termite or pest damage can derail a sale – if you’ve had termites in the past, get a professional treatment and be ready to show documentation. Outdated electrical (like old fuse boxes or knob-and-tube wiring in historic MD homes) is a red flag – consider an electrical upgrade or at least get an electrician’s opinion in advance. Proactively fixing such issues can speed up your sale and even boost your home’s value.
Documentation: It helps to gather service records and receipts for any major repairs or maintenance you’ve done (HVAC servicing, roof work, septic pumping, etc.). Providing these to the buyer can show that the home has been cared for. If you recently replaced a big-ticket item (new furnace, new well pump, etc.), having paperwork ready might reassure buyers and counter any inspection comments about “old system near end of life.”

2. Types of Inspections in Maryland
Homebuyers can opt for several types of inspections beyond the standard home inspection. Maryland’s geography (from urban rowhomes to rural farms to Bay-front properties) means different homes have different inspection needs. Here are common inspection types and how they apply in MD:
Standard Whole-Home Inspection: This is the typical inspection of the house’s structure and primary systems (foundation, roof, exterior, electrical, plumbing, HVAC, interior, etc.). Maryland licensed home inspectors follow a Standards of Practice to perform a visual inspection and report on material defects. They won’t tear into walls, but will test accessible outlets, run appliances, inspect attics and crawl spaces, and so on. This general inspection is usually not required by law, but virtually every buyer should get one for their own protection. Some new construction buyers even hire an inspector for a pre-drywall or final walk-through inspection to catch builder oversights. In Maryland, inspectors must be licensed and have completed training and an exam, ensuring a level of quality. Always hire a reputable, licensed inspector – your real estate agent can recommend trusted names.
Wood-Destroying Insect (Termite) Inspection: Termite and other wood-destroying insect inspections are very common in Maryland due to our climate. While not mandated by Maryland law for all sales, many lenders (FHA, VA, and others) require a termite inspection report (often called a “WDI report”) as part of the loan approval. Even when not required, it’s highly recommended for buyers. Licensed pest control inspectors will look for termites, carpenter ants, beetles, or carpenter bees and any wood damage or active infestation. Maryland uses a standard form (MD Department of Agriculture Form MD-1) for WDI inspections, and most professional inspectors or pest companies will provide findings on this form. If evidence of termites is found, treatment and repairs can be negotiated. Pro tip: Sellers can proactively get a termite inspection and treatment warranty before listing – this can make your home more marketable (buyers love seeing “Termite Certification: No active infestation” in the documents).
Radon Testing: Radon is an invisible, odorless radioactive gas found in soil across Maryland. High levels of radon exposure can cause lung cancer over time. Montgomery County, MD is unique in that it requires radon testing for single-family home sales – since 2016, sellers in Montgomery County must test the home and provide results to buyers (tests must be done within 1 year of closing). For the rest of Maryland, radon testing is optional but wise, especially in counties known to have elevated radon (Frederick, Carroll, Baltimore County, etc., which have areas designated EPA Zone 1 for radon). A radon inspection involves placing a test kit in the lowest livable area of the home for 2–3 days. Many home inspectors are certified to conduct radon tests for an additional fee. If high levels are found (4.0 pCi/L or above), buyers often ask for a radon mitigation system, which a seller can install for roughly $800–$1,500. Maryland also requires sellers to disclose any known radon hazards – even outside of Montgomery County – so it’s in everyone’s interest to test.

Septic System Inspection: Many homes in rural or suburban parts of Maryland are not on public sewer but instead use on-site septic systems. Septic inspections are highly recommended for these properties. A septic inspector (or septic pumping company) will usually pump the tank to examine its condition, inspect distribution boxes, check drain fields, and assess overall function. Maryland law doesn’t force a septic inspection, but it does require that anyone performing a septic inspection for a property transfer be certified by the state (MDE-approved course). In practice, many home purchase contracts add a septic inspection contingency, or buyers do it during the home inspection period. Lenders may require a working septic (no failure) as a condition of financing. If a septic fails inspection (e.g. it’s not treating waste properly or has structural issues), the buyer and seller must negotiate repairs or replacement – which can be costly. There’s no automatic law requiring sellers to fix a failed septic, but the issue becomes a contract negotiation point. In some cases, if no agreement is reached on a bad septic, the contract can be canceled by either party. Tip for sellers: If your home has a septic, consider getting it inspected and pumped before listing, and offer the report to buyers. Transparency can save your deal.
Well Water Testing: Likewise, homes not on public water will have a private well. Starting October 1, 2024, Maryland law (Real Property §10-713) will require that contracts for homes with private wells include a provision for the buyer to perform water quality testing as a condition of sale. The well water test must be done and results reviewed by both buyer and seller before closing, and both must sign off that they’ve seen the results. (The buyer can waive this testing in writing if they choose.) The water test looks for potability issues and contaminants (bacteria, nitrates, perhaps heavy metals depending on local concerns). Results are valid for 3 years for any subsequent sale. Even prior to this law, most Maryland buyers with wells would test the water – but now it’s formalized. Sellers with wells should consider shocking or sanitizing the well and testing it themselves pre-listing to avoid surprises (for example, a common issue is coliform bacteria in well water, which is usually fixable with treatment). Also, yield testing (to ensure the well produces sufficient gallons per minute) can be done if water flow is a concern, though the new law focuses on water quality.
Mold & Environmental Inspections: A standard home inspection will note visible mold-like growth or moisture problems, but it usually won’t include air sampling or lab tests. If an inspector or buyer suspects mold (musty smells, visible patches in attic or basement), the buyer can add a mold inspection or indoor air quality test. Maryland doesn’t mandate mold testing, but mold is a common issue in our humid climate – especially in older Baltimore rowhomes or any house that’s had leaks. In the inspection report, “Signs of mold growth are a huge red flag” and often lead to a recommendation for a specialized mold evaluation. Other environmental tests include lead paint inspections (important for houses built before 1978 – federal law requires sellers to provide a Lead Paint Disclosure, but buyers can test if concerned) and asbestos inspections in very old homes. These specialized inspections are optional and usually at the buyer’s discretion. If you’re buying a home in Maryland that was built decades ago and planning renovations, it might be worth testing for lead, asbestos, or mold so you know what you’re dealing with.
Chesapeake Bay Waterfront Considerations: Maryland’s waterfront properties (along the Chesapeake Bay and its tributaries) require extra attention during inspections. Inspectors will look at shoreline erosion and any measures in place to combat it, such as bulkheads or living shorelines. Flood risk is a big factor – expect discussion of flood zones and whether the home’s elevation is sufficient or if flood insurance is recommended. Saltwater exposure can corrode metal components (railings, HVAC units, plumbing) much faster than inland; an inspection on the Bay will note any rust or corrosion on structures and systems. High humidity near the water also promotes mold and wood rot, so waterfront home inspections pay special attention to ventilation, dehumidifiers, and signs of mildew. If the property has a septic system, the inspector will evaluate whether it’s located and designed to avoid saltwater intrusion or high water table issues. For sellers of waterfront homes, it’s smart to have any shoreline stabilization documents or elevation certificates on hand, and ensure things like dock pilings, sea walls, and crawl space ventilation are in good shape. Chesapeake Bay properties are beautiful but require vigilance against the elements.

3. Maryland Laws & Requirements for Home Inspections
Home Inspections Not Mandatory by Law: Maryland does not require a home inspection by statute for a real estate sale. However, if you do get one, the inspector must be licensed by the Maryland Commission of Real Estate Appraisers and Home Inspectors. Licensing ensures the inspector completed at least a 72-hour training course and passed a national exam. They must also follow Maryland’s Standards of Practice, which dictate how the inspection is conducted and reported. In short: you aren’t forced to hire an inspector, but practically every buyer does – and should.
Montgomery County Radon Testing Law: Montgomery County (covering Rockville, Bethesda, Gaithersburg, etc.) is the only Maryland jurisdiction requiring a radon test during home sales. Since October 2016, Montgomery Co. law says single-family homes (detached and townhouses) must be tested for radon before the sale is completed. Sellers can do the test or allow the buyer to do it, but results have to be provided to the buyer before settlement. This was the first law of its kind in the U.S., aimed at protecting buyers in a high-radon area. Outside Montgomery County, there’s no legal requirement, but Maryland sellers statewide are obligated to disclose any known high radon levels (just as they must disclose other latent defects). In practice, many Maryland buyers will include radon testing as part of their inspection contingency anyway.
Well Water Testing Requirement: A new Maryland law effective Oct 1, 2024 will add a statewide requirement related to homes with private wells. Under Real Property §10-713, any contract for sale of a property with a well must require the buyer to have the well water tested for quality, and both buyer & seller must review the results prior to closing. The buyer can waive this in writing, but otherwise, closing cannot occur until both parties sign off that they’ve seen the water test results. The law doesn’t force any specific action based on the results (other than sharing them with the Maryland Department of the Environment), but it ensures everyone is informed. So, if you’re selling a house with a well in Maryland after 2024, expect the buyers to ask for a water test if you haven’t already done one.
Termite Inspection – Lender and Contract Requirements: Maryland has no state law making a termite inspection obligatory for all sales, but many lenders require a Wood-Destroying Insect report. For example, VA loans on Maryland homes will require a termite inspection in most cases (the VA has no statewide exemption in MD). Even with cash deals or conventional loans, buyers often include a termite inspection contingency in the contract. The Maryland Realtors contract form allows the buyer to have a licensed pest control inspector check for insects and damage. If infestation or damage is found, typically the seller is expected to pay for treatment and repairs, or the parties negotiate a solution. Again, it’s not mandated by law – it’s driven by contract and common practice. Sellers should also note: if you know of past termite treatment or damage, you should disclose that history on the property disclosure statement (even if the problem was resolved), to avoid any appearance of hiding it.
Septic System Certifications: Maryland doesn’t force a septic inspection on sales, but certain counties or rural loan programs may have specific rules (e.g. some counties require septic systems to be pumped/inspected within X years as part of use permits). Maryland’s focus is on regulating the inspectors (with MDE-approved training). Importantly, if a septic system is malfunctioning, many types of financing (FHA, VA, USDA) will not allow the loan to close until it’s fixed. There’s no automatic law saying “seller must fix septic,” but practically speaking a seller will likely have to repair or replace a failing system to keep a deal alive (or find a cash buyer willing to take it on). Maryland also has regulations for nitrogen-reducing septic systems in certain Chesapeake Bay watershed areas, but those usually concern new installations or replacements, not point-of-sale.
Seller Disclosure Law (Maryland Real Property §10-702): Maryland requires sellers of most 1-4 unit residential properties to furnish a Disclosure and Disclaimer Statement to the buyer. The seller can choose to make a full disclosure
