Key Takeaways
- Cost (KC): Covered patio $25-$60/sq ft; screened porch $60-$130/sq ft; sunroom $120-$400/sq ft depending on three- vs four-season
- Seasons of use: Covered patio ≈ 5-6 months; screened porch ≈ 7 months; three-season room ≈ 9 months; four-season sunroom = 12 months
- Permits: All three need permits in most KC-metro cities; a four-season sunroom is a full room addition with energy-code and HVAC inspections
- Resale: Patios and porches recoup the highest percentage; a four-season sunroom adds the most total value because it counts as living area
- Verdict: Covered patio for budget and open air, screened porch for bug-free evenings, sunroom for a true extra room
"We want to enjoy the backyard more" is one of the most common goals we hear, and it almost always leads to the same three-way decision: covered patio, screened porch, or sunroom. They solve overlapping problems at wildly different budgets — roughly $10,000 to well past $100,000 — so picking the right category matters more than any individual design choice.
I'm a 4th-generation Kansas City contractor, and my team has built all three across the metro — from simple roof extensions in Lee's Summit to four-season sunroom additions in Leawood. I don't earn more by steering you to one category, so this is a straight comparison: what each one costs here, how many months a year you'll actually use it, what the city will require, and what buyers pay for later.
The Three Options, Defined
Covered patio: a concrete, paver, or stone patio with a solid roof overhead — either an extension of the house roofline or a freestanding structure. Open on the sides, fully outdoors.
Screened porch: a roofed, floored structure enclosed with screens. It keeps out bugs, birds, and most blowing rain while staying open to breezes. Usually built on a deck-style or slab floor attached to the house.
Sunroom: a glass-walled room attached to the house. A three-season sunroom uses single-pane or lightly insulated glass and no HVAC; a four-season sunroom is a true room addition with an insulated foundation, insulated glass, and its own heating and cooling. Our sunroom installation page shows examples of both.
What Each Costs in Kansas City
These are real-world installed ranges we see across the KC metro. National guides like HomeGuide's sunroom cost data and HomeAdvisor's patio enclosure guide land in similar territory, but local footing depth, roof tie-ins, and finish level move the needle.
Covered Patio
$25 - $60 / sq ftPatio surface plus a solid roof. Most KC projects land between $8,000 and $25,000 depending on size, roof style (tied into the house vs freestanding), and whether the patio slab already exists.
Price drivers:
- • New slab or pavers vs existing patio
- • Roof tie-in to existing roofline
- • Ceiling finish, fans, and lighting
Usable season
~5-6 months
Best for
Budget-friendly shade and open-air living
Screened Porch
$60 - $130 / sq ftA roofed, screen-enclosed room. New builds in the KC metro typically run $20,000-$45,000. Screening in an existing covered structure is far cheaper — often $3,000-$8,000.
Price drivers:
- • New structure vs screening existing roof
- • Floor system (slab vs framed deck)
- • Ceiling, fans, electrical, and screen quality
Usable season
~7 months (Apr-Oct)
Best for
Bug-free evenings with outdoor feel
Sunroom (3-Season / 4-Season)
$120 - $400 / sq ftGlass-walled living space. Three-season rooms run roughly $120-$250/sq ft; true four-season sunrooms with insulated foundations and HVAC run $200-$400/sq ft — $60,000-$150,000+ for most KC projects. See our full sunroom cost guide for Kansas City for a detailed breakdown.
Price drivers:
- • Three-season vs four-season construction
- • Foundation and roof tie-in complexity
- • Glass package and HVAC solution
Usable season
9 months / year-round
Best for
A true extra room that adds square footage
Seasons of Use: The Kansas City Reality
This is the comparison that matters most, because KC weather is genuinely four-season: humid 95-100°F summers, gorgeous springs and falls, and winters that dip into the single digits. Here's how each space actually gets used across the calendar:
Covered patio: great from May through October, with the roof extending use into light rain and blocking the worst of the summer sun. But mosquitoes own KC evenings from June through September, and wind and cold end the season by early November.
Screened porch: the screens neutralize the mosquito problem, which is why porch owners consistently report using the space two to three times more than a comparable open patio. April through October is comfortable; add a ceiling fan and it stays pleasant through most summer evenings.
Three-season sunroom: glass instead of screens extends the season from roughly March through November. On a sunny 45-degree day the room warms itself. It will not be comfortable in January or during a 100-degree heat wave.
Four-season sunroom: a real room. Christmas morning coffee, July afternoons in the AC — it works 365 days a year, which is exactly why it costs what it does.
Permits, Codes & HVAC
All three projects require building permits in nearly every KC-metro city — Kansas City, Overland Park, Lee's Summit, Olathe, Liberty, and the rest. The difference is in how involved the review is.
Covered patios and screened porches are permitted as accessory or porch structures: footing inspections for the posts (KC-area frost depth is 36 inches), framing inspection for the roof, and electrical inspection if you add fans or outlets. Straightforward, typically 2-4 weeks of review.
A four-season sunroom is a room addition, full stop. That means a foundation designed to frost depth, framing and roofing to house standards, energy-code compliance for insulation and glazing, and mechanical permits for HVAC. For heating and cooling, a ductless mini-split is the workhorse solution — efficient, zoned, and no ductwork modifications. Extending the home's existing system is possible but requires a load calculation to confirm capacity. This Old House's porch guide is a good primer on how these structures differ from a code standpoint.
Resale Value & Maintenance
Resale: outdoor living consistently ranks near the top of buyer wish lists in the KC market. Covered patios and screened porches recoup the highest percentage of their cost because the investment is modest and the appeal is universal. A four-season sunroom adds the most total value because heated, cooled square footage on a proper foundation counts as living area in an appraisal. Three-season rooms sit in between: buyers love them, but appraisers treat them as an amenity, not square footage.
Maintenance: covered patios are nearly maintenance-free — occasional slab sealing and roof upkeep. Screened porches need screen repairs every few years and periodic staining if the structure is wood. Sunrooms carry the most upkeep: glass cleaning, seal and caulk inspection, and (for four-season rooms) servicing the mini-split. None of it is burdensome, but it scales with how enclosed the space is.
| Factor | Covered Patio | Screened Porch | Sunroom |
|---|---|---|---|
| Installed Cost (KC) | $25 - $60 / sq ft | $60 - $130 / sq ft | $120 - $400 / sq ft |
| Typical Project | $8K - $25K | $20K - $45K | $40K - $150K+ |
| Seasons of Use | ~5-6 months | ~7 months | 9 mo / year-round |
| Bug Protection | None | Full | Full |
| Permit Complexity | Simple | Simple-moderate | Full room addition (4-season) |
| HVAC | N/A | Ceiling fans | Mini-split (4-season) |
| Counts as Living Area | No | No | Yes (4-season) |
| Maintenance | Minimal | Screens, stain | Glass, seals, HVAC |
Where Each Option Shines
- Covered patio – lowest cost, open-air feel, nearly zero maintenance
- Screened porch – bug-free evenings, best cost-to-use ratio in KC
- 3-season sunroom – glass comfort from March to November without HVAC cost
- 4-season sunroom – true added square footage, usable 365 days
Where Each Option Falls Short
- Covered patio – no bug protection; season ends when the weather turns
- Screened porch – unusable in winter; screens need periodic repair
- 3-season sunroom – sunroom price without year-round use; no appraisal square footage
- 4-season sunroom – by far the highest cost, longest build, biggest permit lift
So Which Should You Choose?
After building all three across the metro, here's the decision framework I walk clients through:
Choose a covered patio if: your budget is under $25,000, you love the open-air feel, and bugs don't drive you inside. It pairs beautifully with a fire pit or outdoor kitchen later, and our patio construction team can design the slab so a roof or screens can be added down the road.
Choose a screened porch if: mosquitoes are the main thing chasing you indoors, you want the best usage-per-dollar in the KC climate, and a spring-through-fall room covers how you actually live. For detailed local pricing, see our screened-in porch cost guide.
Choose a sunroom if: you want a real room — a plant-filled breakfast room, a home office with a view, space that works in January. Go three-season if year-round use isn't essential; go four-season if you want the space to count as living area and hold its value like one.
One more honest tip: if you're torn between two categories, build the structure so it can be upgraded. A covered patio framed to porch standards can be screened later, and a screened porch built on frost-depth footings can become a three-season room. Planning that path up front costs a little more in framing and saves a fortune in rework.
Frequently Asked Questions
How much does each option cost in Kansas City in 2026?
In the Kansas City metro, a covered patio typically runs $25-$60 per square foot ($8,000-$25,000 for most projects), a new screened porch runs $60-$130 per square foot ($20,000-$45,000), a three-season sunroom runs $120-$250 per square foot, and a four-season sunroom runs $200-$400 per square foot ($60,000-$150,000+). Site conditions, roof tie-in complexity, and finish level drive where you land in each range.
Which option can I use year-round in Kansas City?
Only a four-season sunroom is a true year-round space. It is built on a frost-depth foundation with insulated walls, insulated glass, and its own heating and cooling, so it stays comfortable through KC's 100-degree summers and single-digit winter nights. A three-season sunroom is comfortable roughly March through November, a screened porch about April through October, and a covered patio whenever the weather cooperates.
Do I need a permit for a sunroom, screened porch, or covered patio?
In nearly every KC-metro city, yes for all three. Any roofed structure attached to the house requires a building permit, and a four-season sunroom is treated as a full room addition with foundation, framing, electrical, and energy-code inspections. Covered patios and screened porches are usually simpler permits, but they still need footing and framing inspections. Your contractor should pull the permits; if a bid skips them, that is a red flag.
Does a sunroom count toward my home's square footage?
A four-season sunroom that is heated and cooled and built on a proper foundation generally counts as finished living area in an appraisal, which is a big part of its resale value. Three-season rooms, screened porches, and covered patios do not count as living area, though they still add value as desirable outdoor amenities.
Can a screened porch be converted to a sunroom later?
Often, yes, and it is a common phased approach. If the porch is built with a conversion in mind (frost-depth footings, roof framed to house standards, electrical roughed in), swapping screens for windows to create a three-season room is straightforward. Getting all the way to a four-season room is a bigger lift because of insulation, foundation, and HVAC requirements, so tell your builder up front if that is the long-term plan.
Which adds the most resale value?
Dollar for dollar, covered patios and screened porches tend to recoup the highest percentage of their cost because outdoor living is heavily requested and the investment is modest. A four-season sunroom adds the most total value because it adds appraisable square footage, but its higher cost means a lower percentage recoup. The worst outcome is an under-built sunroom that leaks or is unusable in summer; quality matters more than category.
How do you heat and cool a sunroom?
The most common solution we install is a ductless mini-split, which handles both heating and cooling efficiently without tying into the home's existing ductwork. Extending the main HVAC system is possible but requires a load calculation to confirm the furnace and AC can handle the added volume. Three-season rooms usually skip HVAC entirely and rely on ceiling fans and operable windows.
How long does each project take to build?
A covered patio typically takes 1-2 weeks once work begins. A screened porch takes 2-4 weeks. A three-season sunroom runs 4-6 weeks, and a four-season sunroom usually takes 8-12 weeks because it involves foundation work, insulation, drywall, HVAC, and multiple inspections. Permit review adds 2-6 weeks up front depending on your city.
