Year-Round Glass Rooms for Pasadena's Historic Homes
Pasadena homeowners tend to care how an addition looks from the street and how it meets the original house. A glass sunroom is a good fit here because it adds a bright, usable room while staying visually light, so the bungalow, shingle siding, or stucco facade still reads as the main event. We size the roof pitch, frame color, and mullion layout to sit comfortably behind the house rather than compete with it.
Inland Pasadena summers are warm, with July highs typically near 90°, and winter mornings can be cool at the foot of the San Gabriels. A four-season sunroom with insulated framing and CONSERVAGLASS NXT glass handles both. A design consultant visits for a free quote and site check, and we prepare the drawings and submit them to the Pasadena Permit Center. If you'd like to see full-size rooms first, our Buena Park showroom is about a 40-minute drive.

SUNROOMS WE BUILD
Sunroom Designs for Pasadena Homes
Each glass room is drawn to match the character of the house it attaches to. If you only need shade over an open patio, compare our patio covers.
Four-Season Glass Rooms
Insulated frames plus CONSERVAGLASS NXT glazing, which blocks up to 85% of solar heat and 90% of UV, give you a glass room you can heat and cool and use in every month.
Craftsman-Friendly Profiles
Low-slope roofs and earthy frame finishes echo the wide eaves and horizontal lines of a Pasadena bungalow, so the sunroom looks considered rather than bolted on.
Garden Rooms & Conservatories
A gabled glass roof suits Pasadena's mature gardens and old shade trees, turning the back of the house into a light-filled room that looks out on the landscape.
Three-Season Sunrooms
A lighter, lower-cost glass room for spring, fall, and mild winter days, when Pasadena weather is at its best for sitting in the sun.
Foothill & Arroyo Lots
Parts of Pasadena near the Arroyo Seco and the foothills are mapped as Very High Fire Hazard Severity Zones. We check your parcel and specify materials to meet the wildfire construction rules that apply.
Sunroom Renovations
Replace fogged or single-pane glass, tired doors, and worn screens on an older sunroom, or remove it and build a new, better-insulated room in its place.
WHY PASADENA HOMEOWNERS CHOOSE US
A Sunroom Builder Who Respects the House
In Pasadena, the design and the approvals matter as much as the glass. Here's how we approach both.
Designed to Defer to the Original Home
We keep sunrooms subordinate in height and scale, place them toward the rear where possible, and pick finishes that relate to the existing trim and siding.
Historic Review Navigated for You
Pasadena has dozens of designated landmark and historic districts. When a project is visible from the street in one of them, a Certificate of Appropriateness is needed, and we prepare that submittal along with the building plans.
Concurrent City Review
The Pasadena Permit Center routes plans to building, planning, fire, and design and historic preservation reviewers at the same time. We assemble a complete package up front so nothing stalls the review.
California-Made, Lifetime-Warrantied
C-Thru is manufactured in Riverside, Duralum in Sacramento, and Four Seasons at its California plant. Each system carries a transferable lifetime manufacturer warranty.

Factory-trained installers assemble your pre-engineered sunroom, typically in days to a few weeks on site.
Final Sign-Off & Warranty
We meet the city inspector for final approval, walk you through the room, and register your transferable lifetime warranty.
PASADENA SUNROOM FAQs
Pasadena Sunroom Questions, Answered
Pasadena sunrooms generally run $15,000 to $70,000+. Three-season glass rooms usually start around $15,000-$25,000, while insulated four-season rooms with premium glass are about $30,000-$70,000+. That is typically 50-70% less than a conventional room addition. Your exact price comes as a line-item quote after the free in-home visit.
Often, yes. In Pasadena's landmark districts, exterior changes visible from the street need a Certificate of Appropriateness, while exterior alterations not visible from the street are exempt from that review. A sunroom placed at the rear of the house frequently falls in the exempt category. We confirm your home's status and handle any design review submittal.
Pasadena issues its own permits through the Pasadena Permit Center, part of the Planning & Community Development Department. Building, planning, fire, and historic reviewers look at plans concurrently. We prepare the engineering, submit the plans, and schedule every inspection.
Yes, with the right specification. CONSERVAGLASS NXT glass blocks up to 85% of solar heat and 90% of UV, and insulated framing keeps the room stable. For rooms facing west or south, we often suggest a solid or partial-solid insulated roof and a ductless mini-split.
We are an authorized dealer for Four Seasons Sunrooms, C-Thru Sunrooms (made in Riverside, CA), and Duralum (made in Sacramento, CA). All three are manufactured in California and include transferable lifetime warranties.
Plan on a few months from contract to completion, most of it for design, engineering, and city review. Homes that need historic or hillside review can take longer. Once the permit is issued, installation is usually days to a few weeks.
