The short answer
Heritage home insurance is cover for an older or formally designated house where rebuilding means matching original materials and skilled work, sometimes under rules set by a municipal or provincial heritage authority. The key questions are how the rebuild cost is estimated, whether the policy restores like for like or only to a modern functional equivalent, and how old wiring, plumbing and heating are handled. A licensed broker compares insurers that write these homes.
- Owners of a century home with original plaster, millwork or masonry
- Owners of a house designated under municipal or provincial heritage rules
- Buyers of a character home listed on a city heritage inventory
- Owners planning restoration work funded partly by a heritage grant
- Anyone told by an insurer that the home can only be written on a functional basis

01 / What it covers
The parts worth understanding
Rebuild cost for original work
Restoring lath and plaster, hand-cut trim, stained glass or a slate roof calls for trades and materials that cost more than standard construction. An estimate built for a typical house of the same size can fall well short, and some insurers send an appraiser familiar with older homes.
Like for like or functional replacement
A full replacement basis aims to restore the home with materials of similar kind and quality. Functional replacement pays to rebuild with modern materials that do the same job, such as drywall in place of plaster. Ask which one each insurer offers, and for which parts of the home.
Heritage rules on repairs
A formally designated home may need approval before exterior changes, demolition or certain repairs, and the authority may expect original materials or methods. Rules differ by municipality and province, so ask the heritage office what applies and tell the broker.
Code upgrades during a rebuild
After a major loss, current codes may require changes the original house never had. Many policies limit what they pay toward code-driven work unless a by-law or code upgrade option is added, and heritage rules can add requirements of their own.
Partial losses and matching
When one room or one wall is damaged, blending the repair with surviving plaster, trim or brick is often the hard part. Wordings handle matching differently, so ask how an insurer approaches a repair that has to sit beside original work.
Older systems underneath
Original wiring, galvanized or cast iron pipes, an old boiler or a buried oil tank are weighed on their own, and separate pages here cover several of them. Documented updates often matter as much as the age of the house.
02 / Get ready
Bring this, and expect these questions
Gather
- The year the house was built, and any heritage designation, inventory listing or bylaw number
- Any heritage agreement, covenant or grant condition registered against the title
- Photos of original features: plaster mouldings, trim, staircases, fireplaces, windows, stained glass, hardware and the exterior masonry
- A recent rebuild cost appraisal, ideally from someone experienced with older homes
- Invoices and permits for updates to wiring, plumbing, heating and the roof, with dates
- Roof material and age, especially for slate, cedar or metal
- The names of restoration specialists or trades who have worked on the home, and what they did
- Your current policy, showing whether the building is settled at replacement cost or functional replacement
- Plans for upcoming restoration or renovation, and whether heritage approval is needed
A broker will ask
- Is the home formally designated, or only listed on an inventory?
- Which original features remain, and which have been replaced over the years?
- Has anyone estimated the cost to rebuild with matching materials?
- Would you want the home restored as it was, or is a modern equivalent acceptable?
- When were the wiring, plumbing, heating and roof last updated, and is there proof?
- Are there any heritage agreements or grant conditions on title?
- Is restoration or renovation planned, and has the heritage office been consulted?
- Is any part of the home rented or used for a business?

04 / Three situations
See which one sounds like yours
A buyer of a designated Edwardian brick house
A couple is buying a 1912 brick house that the city designated as a historic resource. The designation documents protect the front facade, the porch and the original windows, and the lender wants proof of insurance within two weeks.
First steps. Ask the seller for the designation bylaw and any statement listing the protected features, along with the inspection report. Give the broker those documents with the year built and system updates, and ask which insurers will offer full replacement for protected elements and how quickly an appraisal can be arranged.
A family moved to functional replacement at renewal
A family has lived for twenty years in a 1905 house with original lath and plaster and fir trim throughout. At renewal their insurer moved the building to functional replacement, and the owners are not sure what that changes.
First steps. Ask the insurer to explain in writing what the functional basis means for walls, trim, windows and floors. Photograph the original features room by room, and ask the broker whether other insurers would restore like for like and what an appraisal or update records would need to show.
A small fire beside an original plaster ceiling
A kitchen fire in a 1920s house blackened the adjoining dining room, where the original plaster ceiling medallion and picture rail survive. The adjuster's first estimate prices drywall and stock trim for the whole room.
First steps. Before anything is removed, photograph the damaged and undamaged features and keep any fragments of trim or plaster. Get a written quote from a restoration plasterer or carpenter, and ask the broker or insurer how the settlement basis and matching wording apply to the original details.
05 / Words you will hear
The jargon, in plain words
- Functional replacement
- A way of settling a claim that rebuilds with modern materials performing the same job as the originals, without recreating historic materials or craftsmanship.
- Heritage designation
- Formal legal protection that a municipality or province places on a property, usually by bylaw or order, which can restrict changes to its listed features.
- Character-defining elements
- The specific features, such as a porch, windows or masonry, that a designation identifies as giving the place its heritage value, and that it protects.
- By-law upgrade cover
- Cover, often optional, toward the extra cost of meeting current building codes or bylaws when a damaged home is repaired or rebuilt.
- Lath and plaster
- A wall and ceiling finish common before drywall, with plaster applied in coats over thin wood strips. Repairing it well takes specialized trades.
06 / Common mistakes
What trips people up
- Using a rebuild figure from an online calculator designed around new subdivision construction.
- Assuming heritage designation only matters for renovations, when it can shape how the house must be rebuilt after a loss.
- Not checking whether the policy settles on full replacement or functional replacement until after a claim.
- Discarding damaged original trim or hardware before a restorer has had the chance to copy it.
- Starting exterior repairs on a designated home without asking whether approval is needed first.
- Leaving undocumented the wiring and plumbing updates that make an old house easier to place.

07 / Questions people ask
Straight answers
Is it harder to insure a heritage home?
It can take more preparation. Some insurers are cautious with very old houses, especially when original wiring, plumbing or heating remains, and some offer only functional replacement. Others work with older and character homes regularly and expect detailed information. Documented updates, a credible rebuild appraisal and clear photos of the home give a broker more to work with when approaching several insurers.
What is functional replacement cost?
It is a way of settling a claim that pays to repair or rebuild with modern, commonly available materials that serve the same purpose as the originals, rather than recreating them. Drywall can stand in for plaster, and stock trim for hand-milled mouldings. It often costs less to insure than full replacement, but it does not aim to restore heritage character. Ask exactly which parts of the home it would apply to.
Does heritage designation affect insurance?
It can. A designation may require approval for exterior changes or demolition, and the heritage authority might expect a damaged protected feature to be restored with matching materials, which can raise the cost of a rebuild. Requirements vary by municipality and province, and being on an inventory is often different from formal designation. Bring the designation documents to the broker so insurers can see what is protected.
How is the rebuild cost of a century home estimated?
A reliable estimate looks at the actual materials and workmanship: plaster rather than drywall, solid wood trim and doors, masonry, original windows and roofing. Standard calculators often miss these. Some insurers arrange an inspection or appraisal, and some owners commission one from a firm experienced with older buildings. Revisit the figure after restoration work and whenever building costs move noticeably.
Are heritage grants connected to my insurance?
Some municipalities and provinces have offered grants or incentives for conserving designated homes, and some come with agreements about maintaining the property. Those agreements are separate from insurance, but they may set expectations about how protected features are repaired after damage. Read any agreement for such conditions and share it with the broker. Programs and their rules change, so confirm the details with the heritage office.
Do old systems in a heritage home need updating before it can be insured?
Not always, but they are weighed carefully. Insurers often ask specifically about knob and tube or other early wiring, the electrical service, galvanized pipes, the heating system and any oil tank. Some will write a home with older systems under conditions; others want them replaced first. The separate pages on wiring, oil tanks and older roofs explain what brokers usually ask about each one.
