Does homeowners insurance cover a greenhouse?

Usually yes, if it's a personal-use backyard structure on your property. A detached greenhouse typically falls under Coverage B (Other Structures) on a standard homeowners policy, alongside sheds, detached garages, and gazebos — no separate greenhouse policy required for most hobby setups. The catch is the coverage limit: Coverage B is usually capped around 10% of your dwelling coverage amount, and it doesn't cover what's inside.

How much other-structures coverage do I actually have?

Check your declarations page for the Coverage B limit, but as a rule of thumb it's about 10% of your dwelling (Coverage A) amount. A policy with $450,000 in dwelling coverage typically carries roughly $45,000 in other-structures coverage — shared across every shed, fence, detached garage, and greenhouse on the property, not $45,000 per structure. A single expensive polycarbonate kit plus an existing garage and shed could eat that limit fast.

Is plants and equipment inside the greenhouse covered too?

No — that's a separate coverage. Other Structures coverage protects the building itself (frame, glazing, foundation), not its contents. Tools, pots, grow lights, heaters, and the plants themselves fall under your policy's personal property coverage instead, which has its own limit and its own list of covered perils. Check both limits, not just one, before assuming a full loss is covered.

Do I need a different policy if I sell what I grow?

Likely yes. Standard homeowners policies generally exclude structures used for business purposes, so a greenhouse you're using to grow produce, cut flowers, or starts for a farmers market or online sale can fall outside your homeowners coverage entirely. That shifts you into farm or small-business property insurance territory — a different product from the personal 'other structures' coverage this guide is about.

Should I call my insurer before building a greenhouse?

Yes, especially for anything beyond a small kit. A cheap pop-up tunnel rarely changes anything about your policy, but a large permanent kit can be expensive enough to bump against your Coverage B limit on its own, and some insurers want to know about new permanent structures regardless of value. A five-minute call confirming your current other-structures limit and whether the new kit fits under it is cheap insurance against a partial-coverage surprise after a storm.

Do You Need Greenhouse Insurance? What Your Homeowners Policy Actually Covers (2026)

Quick Answer: For most backyard growers, a greenhouse is already covered — as an “other structure” under Coverage B of a standard homeowners policy, the same category as a shed or detached garage, typically up to around 10% of your dwelling coverage amount. What it doesn’t cover: anything growing or stored inside (that’s personal property coverage, a separate limit), and any greenhouse used to grow or sell produce commercially (that needs farm or business coverage instead). Check your declarations page for the actual Coverage B number before assuming a large kit is fully protected.

Most of what gets written about greenhouses is which one to buy or how to keep it warm. Almost nobody covers what happens if a windstorm takes the roof off one — because for most hobby growers, the honest answer is “your existing homeowners policy already handles it,” just not without limits worth knowing about first.

Greenhouse insurance by the numbers: a standard homeowners policy’s Other Structures coverage (Coverage B) is typically capped at about 10% of your dwelling (Coverage A) limit, according to insurance-industry guidance from Hippo — so a policy with $450,000 in dwelling coverage carries roughly $45,000 in combined other-structures protection, shared across every shed, fence, detached garage, and greenhouse on the property, not issued separately per structure. That same guidance confirms Coverage B is automatically bundled into most homeowners policies (you can’t opt out of it), but explicitly excludes structures used for business or short-term-rental purposes and doesn’t extend to the contents inside.

What’s actually covered, and what isn’t

What you're protecting	Coverage type	Typical limit	Covered?
The greenhouse structure itself (frame, glazing, foundation)	Coverage B — Other Structures	~10% of dwelling coverage, shared across all structures	Usually yes, for personal use
Tools, pots, grow lights, heaters stored inside	Personal property coverage	Separate limit, set by your policy	Usually yes, subject to that limit
The plants themselves	Personal property coverage (often a low sub-limit for plants)	Often capped low, e.g. per-plant or per-event limits	Sometimes — check your specific policy wording
Greenhouse used to grow/sell produce commercially	Farm or business property insurance	Separate policy entirely	No, homeowners policies generally exclude business use
Flood damage to any of the above	Separate flood insurance	Separate policy entirely	No, standard homeowners policies exclude flood

Why “other structures” is the category that matters

Insurers don’t have a line item for “greenhouse.” When one shows up in an underwriting file, it gets classified the same way a shed, detached garage, gazebo, or guest house does: an “other structure” on the same property as the insured dwelling. That’s genuinely good news for anyone with a small walk-in kit or mini greenhouse — no separate policy to shop for, no extra premium in most cases, since Coverage B typically comes bundled into a standard policy at no additional cost for its default limit.

The friction shows up at the higher end. A serious large greenhouse kit or a glass structure like our best Exaco greenhouse picks can run well into four figures — sometimes low five figures once a real foundation and utilities are added, as our how much does a greenhouse cost guide breaks down. If that single structure, plus an existing detached garage and shed, adds up to more than the shared Coverage B limit, a total loss won’t be fully reimbursed even though the greenhouse itself is technically “covered.”

Confirm your Coverage B limit before you order a large kit

Check your policy's declarations page · look for "Other Structures" or "Coverage B" · compare against the kit price plus foundation and electrical

If a large kit alone would exceed your current limit, ask your agent about raising it — usually a small premium increase rather than a new policy.
Anchoring matters here too: a kit that isn't properly secured is more likely to become a partial, argument-prone claim after a storm. Our best greenhouse anchor kit picks cover wind-rated anchoring.

The line between “personal use” and “business use”

The other place homeowners coverage quietly stops is commercial activity. If a greenhouse is purely for your own tomatoes and seedlings, it stays squarely inside Coverage B. The moment it’s regularly producing plants, cut flowers, or starts that get sold — at a farmers market, roadside stand, or online — most homeowners policies treat that as business use, which Coverage B specifically excludes. At that point the structure needs farm insurance or small-business property coverage instead, a genuinely different product with its own underwriting, not just an add-on to the existing homeowners policy.

This distinction matters even for casual sellers. You don’t need a large commercial range to trip it — a backyard nursery selling starts a few weekends a year can already be outside personal-use coverage, and liability is part of the exposure too: if a customer is hurt on the property or alleges a plant-related issue, personal liability coverage on a homeowners policy generally isn’t built to handle that either. Anyone selling regularly, even part-time, is worth a conversation with an agent about a business rider rather than assuming the homeowners policy stretches to cover it.

What to actually do before (or after) you buy

Pull your declarations page and find the Coverage B number. It’s usually listed as a flat dollar amount, not a percentage — that’s the real ceiling across every non-dwelling structure on your property.
Add up what’s already using that limit. A detached garage, shed, fence, and gazebo can already be drawing on the same shared pool a new greenhouse would join.
Call before ordering anything large. A large greenhouse kit or a heavy glass structure is worth a five-minute call to confirm it fits, especially once a foundation and wiring for a heater are factored into the replacement cost.
Separately check your personal property limit if the plants and equipment inside represent real value — a mature citrus or bonsai collection, for instance, can be worth more than the structure housing it.
Flag business use honestly. If there’s any regular selling involved, ask specifically whether it needs to move to a farm or business policy rather than assuming the homeowners policy already stretches to cover it.

The bottom line

For the large majority of backyard growers, a greenhouse is already insured the moment it goes up — bundled in as an “other structure” alongside the shed and the fence, no extra shopping required. The two things worth actually checking are the dollar limit on that shared Coverage B pool (not just whether coverage exists) and whether any selling activity has quietly pushed the structure into business-use territory that a personal policy doesn’t reach. Both take one phone call to confirm, and both are far cheaper to sort out before a claim than during one.
