What is the cheapest type of enclosure I can add in Palm Beach County?

A screen porch enclosure is the most affordable option, ranging from $4,650 to $13,950 for a 200 square foot space. This provides insect protection and shade without climate control. However, you will need screens rated for hurricane zones, which adds some cost compared to inland areas.

Why do sunroom costs in Palm Beach County require hurricane-rated materials?

Palm Beach County has a FEMA hurricane risk score of 99.87 (Very High). Local building codes require impact-resistant glass or approved shutter systems for any enclosed addition. These materials add $2,000 to $8,000 to project costs compared to standard glazing used in non-coastal regions.

Do I need AC in a 4-season sunroom here?

Yes. With 2,758 cooling degree-days annually and average summer temperatures, an unair-conditioned sunroom will be unusable from May through September. Budget for HVAC extension or a ductless mini-split system, plus low-E glass to reduce solar heat gain by 25-40%.

How much does electricity cost to cool an enclosed sunroom?

At the current Florida rate of $0.158 per kWh, expect $200 to $500 in additional annual cooling costs for a 200 square foot climate-controlled sunroom. High-performance glass and proper insulation can reduce this toward the lower end of that range.

What do carpenters charge for sunroom installation in this area?

Carpenters in the Miami-Fort Lauderdale-Pompano Beach metro area earn an average of $25.97 per hour. Labor accounts for 40-50% of total project cost, with the remainder going toward materials, permits, and any subcontracted electrical or HVAC work.

Will a sunroom addition increase my property taxes?

Permitted additions become part of your assessed home value. With Palm Beach County's median property taxes at $3,600 annually on a $407,300 median home value (roughly 0.88% effective rate), a $35,000 sunroom could add approximately $300 per year to your tax bill.

Is a 3-season sunroom practical in South Florida's climate?

A 3-season sunroom works well from November through April when temperatures moderate. During summer months with high heat and humidity, comfort depends entirely on ventilation. If you want year-round use, the 4-season option with AC (averaging $35,340 locally) is the better investment.

Why Palm Beach County prices look like this.

Is that unused patio space worth converting into a year-round living area? For Palm Beach County homeowners, the answer often depends on budget and intended use. A basic screen porch enclosure runs $4,650 to $13,950, while a fully insulated 4-season sunroom ranges from $23,250 to $51,150 for a 200 square foot addition. The county's median home value of $407,300 (2.36x the national average) means sunroom additions can deliver strong returns on higher-value properties. Your final price depends on the enclosure type, foundation requirements, and whether you need climate control for Florida's intense summers.

Carpenter and Installation Labor Costs

Sunroom construction in Palm Beach County draws from the Miami-Fort Lauderdale-Pompano Beach labor market, where carpenters earn an average of $25.97 per hour ($54,030 annually). This rate falls slightly below the national carpenter average of $29.58/hr, which contributes to the 0.93x local cost adjustment applied to project estimates. The metro area employs approximately 10,100 carpenters, providing a solid labor pool for residential projects. Labor accounts for roughly 40-50% of total sunroom costs, with the remainder covering materials like aluminum framing, glass panels, and roofing components. Complex projects requiring electrical, HVAC, or foundation work will involve additional trade specialists beyond the primary carpentry crew.

Hurricane and Storm Considerations

Palm Beach County carries a FEMA National Risk Index score of 99.20, placing it among the highest-risk areas in the nation. Hurricane risk scores 99.87 (Very High), meaning any sunroom or enclosure must meet Miami-Dade hurricane code standards for impact resistance. Lightning risk also ranks at 99.81 (Very High), requiring proper grounding and surge protection for electrical systems. Coastal flood risk (93.40) and inland flood risk (98.92) both rate as Relatively High, so elevation and drainage planning matter for ground-level additions. Tornado risk scores 93.80. Expect permit reviewers to scrutinize wind load calculations, and budget for impact-rated glass or approved shutter systems. These requirements add $2,000 to $8,000 compared to non-coastal installations.

Climate Zone and Year-Round Comfort

Palm Beach County sits in IECC Climate Zone 1A (hot-humid), the warmest classification in the building code system. With only 1,472 heating degree-days annually (60% below the national median of 3,700 HDD), heating demand is minimal. The real concern is cooling: 2,758 cooling degree-days annually means air conditioning runs heavily from April through October. For 3-season sunrooms, adequate ventilation and ceiling fans may suffice during shoulder months, but summer use without AC will be uncomfortable. 4-season sunrooms require insulated glass (low-E coatings), properly sized HVAC extensions, and reflective roofing materials to manage solar heat gain. The DOE classifies this as the Southeast HVAC region, where cooling loads dominate energy planning.

Electricity and Cooling Costs

Florida residential electricity averages $0.158 per kWh as of February 2026. A climate-controlled 4-season sunroom adds roughly 150-300 square feet of conditioned space, increasing annual cooling costs by $200 to $500 depending on insulation quality and glass specifications. Palm Beach County receives 5.71 peak sun hours daily, making solar panels a viable offset strategy. A 6kW rooftop system generates approximately 9,372 kWh annually here, enough to cover a sunroom's added load and then some. Low-E glass with argon fill can reduce solar heat gain by 25-40%, directly lowering AC runtime. Screen enclosures avoid these energy considerations entirely but sacrifice climate control.

Financing Your Sunroom Addition

With the 30-year mortgage rate at 6.36% (as of May 14, 2026), many homeowners finance sunroom additions through home equity products rather than cash. A $35,000 4-season sunroom financed over 15 years at current rates adds roughly $300 to monthly payments. Palm Beach County's median home value of $407,300 and annual property taxes of $3,600 suggest most properties carry sufficient equity for these projects. Some contractors offer 12-month same-as-cash financing, though rates climb steeply after promotional periods. Permit-pulled sunroom additions that meet code requirements become part of your home's assessed value, potentially increasing both resale price and property tax obligations.
