"Loved working with Mark and his guys! Love our new sunroom even more! Mark was open and honest from the very first call, never salesy. He was a great resource in helping us finalize the design."

Sunrooms built for Howard County homes
Howard County is really three different places to build a sunroom. Columbia's planned villages come with architectural review. Ellicott City brings hillsides and older homes. Western Howard around Clarksville, Glenelg, and Highland means acreage, custom homes, and open exposure. We design and build three-season rooms, insulated four-season rooms, screen rooms, and porch enclosures across all three with our own crews. As an authorized Sunspace dealer that also handles the structure and the roof tie-in, we keep the whole room under one company.
Planning a sunroom in Howard County
In Columbia, the Columbia Association architectural committee reviews most visible exterior changes, and a sunroom is about as visible as it gets, so we prepare that submission during design. In Ellicott City, slope decides what can support a room, and many projects need engineered footings and stepped framing before the enclosure is even discussed. In the rural west, large lots leave room to size the space properly, while open sites gain and lose heat quickly, which makes orientation and the choice between a three-season and four-season room especially important. We sort through all of that on the first call and the site visit.
Investment Guide
Sunroom options and typical prices
| Option | What it is | Typical price |
|---|---|---|
| Sunspace Model 100 screen room | An aluminum screen room for bug-free open air, upgradeable to windows later. | $12,000 to $35,000 |
| Sunspace Model 200 WeatherMaster | Our most popular three-season room, with vinyl windows that open up to 75 percent. | $38,000 to $80,000 |
| Sunspace Model 300 glass sunroom | A bright glass three-season room with double roller windows that vent from both sides. | $42,000 to $85,000 |
| Sunspace Model 400 insulated sunroom | A fully insulated four-season room with Low-E argon glass for year-round use. | $75,000 to $120,000 |
| Walls-under porch enclosure | Windows and walls added under the roof of a porch or covered deck you already have. | $22,000 to $68,000 |
| Patio cover | A solid insulated, clear acrylic, or hybrid roof over an existing deck or patio. | $10,000 to $40,000 |

Permits and Inspections
Howard County sunroom permits
Howard County permits go through the Department of Inspections, Licenses and Permits, and structures attached to a home need a building permit. In Columbia we file for Columbia Association architectural review alongside the county permit. Howard County is landlocked, so there is no Chesapeake Critical Area review here, though Ellicott City's historic Main Street area carries preservation review.
One company, start to finish
It helps to know who does what. A sunroom dealer sells the enclosure. A sunroom installer assembles it. We are the contractor, which means we are responsible for the footing, the structure, the roof tie-in, the permits, the electrical, and the enclosure itself.
Our own crews build the whole room, so one company answers for every part of it, from the first conversation to the final inspection.
How It Works
Three steps to a firm price
- 1
A free phone conversation
Tell us about your house and how you want to use the room. You get a price bracket on the first call, so you know where the project lands before anyone visits.
- 2
A one-hour site visit
We look at what the room will sit on and how it ties into your house, and we bring samples and colors so you can see the options in person.
- 3
A to-the-penny written proposal
You get a written proposal with the final number, to the penny, so there are no surprises when the work starts.

Questions
Sunroom questions from Howard County homeowners
Do I need Columbia Association approval for a sunroom?
In most Columbia villages, yes. A sunroom is a visible exterior change, so it typically needs Columbia Association architectural committee approval in addition to the Howard County building permit. We prepare that review during design so it runs alongside the county process.
How much does a sunroom cost in Howard County?
Most sunroom additions we build cost about $38,000 to $120,000 depending on the model and size. A screen room runs about $12,000 to $35,000, and enclosing an existing porch runs about $22,000 to $68,000. You get a price bracket on the first phone call and a final written number after the site visit.
Do you handle the Howard County permit?
Yes. Every sunroom we build is permitted and inspected. We prepare the plans, submit them, meet the inspector, and handle HOA or architectural review where it applies.
Which sunroom is most popular?
The Sunspace Model 200 WeatherMaster. Its vinyl windows open up to 75 percent for the breeze and close tight against weather and bugs, which makes it a comfortable three-season room. For year-round use, the insulated Model 400 is the four-season option.
Do sunrooms connect to my home's heating and cooling?
No. We give sunrooms their own heating and cooling, such as a ductless mini-split, rather than tying into your home's system, and we coordinate the electrical it needs.
