Buying a house on Cape Cod means reading more reports than buyers inland are used to. The home inspector covers the structure and systems, as anywhere. But almost every Cape house has a septic system that has its own state-mandated inspection, many sit in mapped flood zones, a number fall inside nitrogen-sensitive watersheds or the National Seashore, and a good share have been closed and unheated for months before you walk through. A Cape-savvy inspector knows which of those questions to raise and which belong to someone else.
Is a Title 5 inspection separate from a home inspection?
Yes, and confusing them is one of the most expensive mistakes a Cape buyer can make. The home inspection is your report, ordered by you, on the condition of the house. The Title 5 inspection is a state-required evaluation of the septic system, done by a state-approved system inspector, and in most sales it is the seller's obligation.
Under the state's Title 5 rules, the septic inspection must be done within two years before the sale, or up to six months after it if the weather prevents an inspection and the buyer is told in writing. If the system fails, it must be repaired or replaced within two years of the inspection. Local boards of health in towns such as Barnstable, Falmouth and Orleans can add requirements.
Read the Title 5 report as carefully as the home inspection. A system that "passes" may be near the end of its life, and a "conditional pass" can come with conditions you inherit.
Is the septic in a nitrogen-sensitive area?
This question is newer and specific to the Cape. Since 2023, impaired Cape watersheds have carried a state nitrogen-sensitive designation. The alternative open to a town is a 20-year watershed permit issued under 314 CMR 21.00, usually built around sewers and other town-wide measures. Where a town does not take that route, owners in the designated watersheds may have to install nitrogen-reducing septic technology. The status varies by watershed and town, so ask the local health department about the specific address.
A home inspector will not settle this, but a good one will tell you to ask. The answer can change what the house will cost you over the next decade.
Should you test for radon on the Cape?
Yes. The EPA's position is that every home should be tested regardless of the zone its county falls in; its Massachusetts radon map explains the zones. A radon test during the inspection period is inexpensive and takes a few days. Many home inspectors offer it as an add-on; ask how they place the test and how they make sure windows stay closed.
If the house draws its water from a private well rather than a town system, add a water test as well.
Is the house in a flood zone or in the National Seashore?
Cape flood maps date from July 16, 2014, and FEMA's Map Service Center shows the panel for any address. Lenders often require flood insurance for a house in a mapped zone, and the zone also limits what you may build later. Look up the address before you make an offer, and ask your insurance agent for a quote early.
In Eastham, Wellfleet and Truro, a house inside the Cape Cod National Seashore has its own rules. Privately owned houses there are protected from federal condemnation by a certificate of suspension that depends on following the Seashore zoning; the Park Service's application form shows what is involved. If you plan to add on, find out before you buy.
What should an inspector look for in a house that sat closed all winter?
Many Cape houses come on the market in spring after months with nobody inside. Winter leaves damage that a quick walk-through can miss, so ask the inspector how they approach a seasonal house:
- Freeze damage. Split supply lines, cracked fittings and toilet tanks, and a water heater that froze. If the house was drained, have the seller's plumber refill it before the inspection so fixtures can run.
- Heating system. A boiler or furnace that has not run for months may start fine and fail a week later. Ask whether the inspector runs it long enough to see it cycle, and consider a separate service visit from a heating technician.
- Oil and propane tanks. Ask about the age and condition of an oil tank, inside or buried, and who owns a propane tank, since many are leased from the dealer.
- Rodents. Droppings, chewed wiring and nesting in insulation are common after a closed winter.
- Roof and attic. Look for stains from ice, wind-driven rain or a missing shingle after a storm.
- Mold. A closed, unheated house with a damp crawl space or basement can grow mold on stored items and framing.
Inspectors who work across the Cape, from Bourne to Provincetown, see these patterns every spring. Ask how many seasonal houses they inspected last year.
How do you check a home inspector's license?
Home inspectors in Massachusetts work under a state license issued by their own board; you can find it on eLIPSE. Search the inspector's name and check that the license is active.
Beyond the license, ask:
- How many Cape houses have you inspected, including seasonal and waterfront houses?
- Do you go into crawl spaces and attics, and onto the roof if it is safe?
- Do you offer radon, water, and wood-destroying insect inspections?
- When will I get the report, and does it include photos?
Which add-on inspections matter most for a Cape purchase?
Beyond the standard inspection and radon, buyers here often add:
- A wood-destroying insect inspection, which some lenders require, for termites and carpenter ants in sills and porches.
- A chimney inspection by a chimney professional, especially for an older masonry chimney or a fireplace the seller rarely used.
- An oil tank evaluation for a house heated with oil, including whether there is or was a buried tank.
- A water test if the house has a private well.
- A heating system service, since a boiler that ran fine during a short test may not have been serviced in years.
Not every house needs every test. Ask the inspector which they would order on this house and why, and ask for prices up front, so you can decide before the inspection day.
Which add-on tests raise a Cape inspection fee, and which are worth it?
For a single-family house under 2,000 square feet, the market's calculator puts the inspection at about $500 to $710; the Cape Cod home inspection cost page shows how size and add-ons change it. Radon, water, and insect tests add to the fee. The Title 5 inspection is a separate cost, usually paid by the seller.
Spring is the busy listing season on the Cape, and inspectors book up. If you are making offers in Yarmouth or Mashpee in April or May, line up an inspector before you need one.
