The City’s line
Sunroom and enclosed porch permits in Fort Worth: porch or room
Porch or room, it takes a building permit. Fort Worth’s code requires one to build or alter any structure, and its list of work that needs no permit doesn’t name a porch or a sunroom. The City’s own residential code then sorts it two ways.
A porch with screens or glass can still count as a patio cover. The City’s code lets it have walls of any shape, as long as at least 65 percent of two walls stays open or glazed and it stays one story, 12 feet or under.
“Patio covers shall be used only for recreational, outdoor living purposes and not as carports, garages, storage rooms or habitable rooms.”
A sunroom you heat, cool or live in is a room, and the City’s patio cover rules no longer fit it. Built new onto the house, it’s filed as an addition.
“All additions require building permits.” And energy code compliance “if adding conditioned or heated space, or lighting”.

Tell us how you want to use the room, and we’ll tell you which side of the line it’s on.
The 65 percent wall
How open does a porch have to stay to count as a patio cover?
To stay a patio cover, at least 65 percent of two walls stays open or glazed: the longer wall and one more, measured from the floor up to 6 feet 8 inches.
- What can fill the openings
- Insect screen, approved clear or translucent plastic up to 1/8 inch thick, glass that meets the code’s glazing section, or a mix.
- How tall
- One story, 12 feet or under.
- What it’s for
- Outdoor living. Not a garage, a carport, a storage room or a room you live in.
- 6 ft 8 in: the City measures each wall below this line
- Open or glazed: 65 percent or more
- Solid wall: 35 percent or less
- Above the line: not counted
“Enclosure walls shall be permitted to be of any configuration, provided the open or glazed area of the longer wall and one additional wall is equal to at least 65 percent of the area below a minimum of 6 feet 8 inches (2032 mm) of each wall, measured from the floor.”
The house behind it
Can a bedroom window open onto an enclosed porch?
Not if that window is the bedroom’s way out in an emergency. The City’s code lets windows open onto a patio cover for light and air, but if one is a bedroom’s escape window, the patio cover has to stay unenclosed.
Doors have their own rule. If a door out of the house opens into an enclosed porch, the porch needs its own way out that meets the code’s exit rules.
Check this before you pick screens or glass. Closing in the porch can trap the window a bedroom depends on. Building it as a room instead doesn’t make that window safe to close in.
Walk the porch with us and we’ll look at every window and door that opens onto it.
A sunroom addition
What a sunroom addition needs from the City
A new sunroom takes the same permit any addition takes. The City’s permit sheet files construction attached to the house as a Residential Addition, and its example is “adding an attached covered porch or patio cover”. It doesn’t name closing in a porch that’s already there, so ask the City which permit yours is filed under.
-
The drawings and the energy paperwork Drawings for the permit, plus the energy code paperwork the City’s permit table asks for when you add heated or cooled space.
-
The foundation Any new foundation or footing, and any addition to a post-tension slab, is designed and sealed by a Texas-registered engineer. We work with licensed outside engineers for that. The City’s wording doesn’t cover new walls on an existing porch slab, so have an engineer check the slab before walls go on it.
-
The trade permits and inspections New circuits, lights or heat and air take their own permits. “Aside from your building permit, you still must obtain all trade permits that are needed separately and schedule inspections as required for each permit type.”
If an inspector needs to see behind finished work
The City says that if an inspector needs finished work opened up, the cost is yours: “Neither the Building Official nor the jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.”
Who does what
Who pulls a sunroom permit in Fort Worth
On our additions, our team walks the permit through the City. A sunroom is one of the additions we draw.
You tell us whether it’s a porch you’ll sit on in April or a room you’ll use in August. We draw it to the side of the line you choose and take the drawings to the City.
Do I need a permit to screen in a porch in Fort Worth?
Yes. Screening in a porch alters a structure, and the City’s code requires a building permit for that. Nothing on its list of work that needs no permit covers it.
Can I put heat and air in an enclosed porch?
Yes, but then it’s a room, not a patio cover, in the City’s code. A patio cover can only be used for outdoor living, never as a room you live in, and the City’s permit table asks for energy code paperwork when you add heated or cooled space. Ask the City which permit it’s filed under.
What can I enclose a porch with and keep it a patio cover?
Insect screen, approved clear or translucent plastic up to 1/8 inch thick, glass that meets the code’s glazing section, or a mix. The longer wall and one more wall have to stay at least 65 percent open or glazed up to 6 feet 8 inches.
Does a sunroom need an engineer in Fort Worth?
A new foundation does. The City’s residential code says every foundation or footing it covers, and any addition to a post-tension slab, is designed and sealed by a Texas-registered engineer. The City’s wording doesn’t cover new walls on an existing porch slab, so have an engineer check the slab before walls go on it.
Can a bedroom window open onto an enclosed porch?
Not if it’s the bedroom’s escape window. The City’s code says the patio cover has to stay unenclosed when an escape window from a bedroom opens into it.
Can I pull my own sunroom permit in Fort Worth?
Yes, if the house is your homestead: you own it, live in it as your primary residence and have the appraisal district’s homestead exemption. Otherwise the City requires a registered building contractor to apply.
Does a sunroom count toward lot coverage in Fort Worth?
Yes. The Zoning Ordinance counts the area under every roof on the lot toward your district’s maximum lot coverage. That’s 50% of the lot in A-5 and 45% in A-7.5.
