Common Challenges in Sunroom Additions
While rewarding, sunroom projects can present challenges:
- Design Matching – Aligning new roofing and siding with your existing home.
- Energy Efficiency – Ensuring windows and insulation meet Greenville’s seasonal climate needs.
- Hidden Costs – Foundation repairs or electrical upgrades may arise during construction.
We anticipate these challenges early, helping you plan and budget effectively.
Cost of a Sunroom Addition in Greenville, SC
On average, sunroom additions in Greenville range between
$80–$250 per sq. ft. , depending on design, materials, and features. A modest 12x12 sunroom may cost $11,520–$36,000, while a larger, four-season space with HVAC integration will be higher.
We provide upfront, transparent estimates tailored to your project.
What Goes Into the Cost of a Sunroom Addition?
The price varies based on several factors:
Size & Design – Larger sunrooms with custom layouts cost more than smaller, standard designs.
Windows & Glass – Energy-efficient glass packages can significantly impact the budget.
Foundation & Roofing – Depending on your home’s structure, new foundation or roof tie-ins may be needed.
HVAC Integration – Adding heating/cooling for four-season usability increases costs.
Finishes & Materials – Flooring, trim, and lighting choices affect the final price.
While screened rooms and three-season options are more affordable, four-season sunrooms often deliver greater long-term value due to year-round usability.
Will a Sunroom Addition Add Value to My Home?
Yes. In Greenville’s active housing market, a sunroom addition often increases resale value and buyer appeal. According to industry reports, homeowners typically recoup 50–60% of a sunroom’s cost at resale.
Why it makes sense locally:
- Greenville’s growing housing market means buyers seek versatile living spaces.
- Families and retirees value sunrooms as multi-use areas (dining, office, or relaxation space).
- Homes with light-filled, flexible spaces tend to sell faster.
Think of it as both a lifestyle upgrade and an investment in long-term equity.
How Long Does a Sunroom Addition Take?
The timeline depends on the design complexity and permit process. Here’s a general guide:
- Smaller screened or three-season rooms – 2–4 weeks.
- Four-season or custom-designed sunrooms – 3–5 months.
We provide clear schedules and regular updates so you always know what to expect.
Do We Need Permits for a Sunroom Addition in Greenville?
Yes. Greenville County requires permits and inspections to ensure all additions meet safety and zoning codes.
As your contractor, we handle:
- Permit applications with the county.
- Inspections for electrical, structural, and safety compliance.
- Zoning compliance for setbacks, lot coverage, and neighborhood rules.
Skipping this step risks costly delays—working with an experienced contractor avoids that hassle.
