Pasadena is a city that cares about its houses. From the Craftsman bungalows that line its older streets to Spanish Revival homes, post-war ranches and hillside houses above the Arroyo Seco, much of the city’s character lives in its architecture. So when a Pasadena homeowner thinks about a sunroom or patio room, the first question is usually not the size or the glass. It is whether the new room will look like it belongs. California Sunroom Price works with homeowners in Pasadena and the surrounding areas, including Altadena, South Pasadena, San Marino and Arcadia.

You will not find a flat price here. Instead, this page explains how design choices, the age of the house and the San Gabriel Valley climate come together in a Pasadena quote.

How do you add a room that fits an older Pasadena home?

Match the roofline

Older homes often have low-pitched gables, deep eaves or tile roofs. The shape and height of the new roof, and where it meets the house, do more than anything else to make an addition look original or tacked on. A cathedral roof can echo a gable, while a lower sloped roof tucks under a deep eave.

Choose colors and details with care

Frame colors, trim and the finish of solid wall sections can be selected to work with wood siding, stucco or brick. Rooms come in hundreds of combinations, and our customization page shows how wide the range is.

Consider a conservatory style

For a traditional or period home, a conservatory-style sunroom with more formal proportions often feels right at home in a garden setting.

Respect the garden

Many Pasadena yards have mature oaks, camellias and established plantings. Room placement and size are planned so the garden stays the star of the view.

How much does a sunroom cost in Pasadena? What drives the price

Rooms are manufactured in California, and the price follows the style, size and features you choose, plus what your site needs.

Room type

Patio covers, pergolas and screen rooms are the lightest projects. Glass enclosures come next. Insulated patio rooms and glass sunrooms are complete rooms meant for year-round living.

Style and roof

A studio sunroom with a single sloped roof is the most straightforward. A cathedral roof adds height and presence. A solarium with an all-glass roof brings in the most light. Each adds a different amount of framing and glass.

Glass

Low-E glass and other energy-efficient glass options reduce heat gain and glare, which matters in Pasadena summers. They cost more than basic glass and are among the most worthwhile upgrades. Read more on our energy efficiency and tests page.

The house connection

Older homes may have raised wood floors, uneven additions from past owners or unusual door locations. Tying a new room into the house cleanly can take more planning, and the estimator will look closely at where the room meets the home.

Slab and grade

A patio room can often use an existing slab in sound condition. Older slabs, brick patios and sloping yards near the Arroyo may need new concrete or extra site work.

Doors, windows and finishes

French-style hinged doors, sliding doors, operable windows and custom colors all contribute to the price and to how well the room suits the home.

How does Pasadena’s climate affect what you should buy?

Pasadena sits at the foot of the San Gabriel Mountains. Summers are hot, often much hotter than the coast, winters are mild with cool nights and some rain, and fall can bring dry, gusty wind.

Heat

An insulated roof is the most effective defense against summer heat. For a glass room, energy-efficient glass is essential, especially on south- and west-facing walls.

Wind

Homes toward the northern edge of the city feel stronger downslope wind events. Solid aluminum framing and proper anchoring keep a room steady.

Winter use

A closed room with good glass stays comfortable on cool winter evenings, turning the patio into a space you use all year instead of mostly in spring.

Sunroom, patio room or enclosure: which fits your Pasadena home and budget?

Insulated patio room

A patio room with an insulated roof and walls that match the house is the most practical choice for a study, family room or guest space, and it handles summer heat well.

Sunroom and patio room options in Pasadena

Glass sunroom

A studio, cathedral or conservatory-style sunroom suits homeowners who want to enjoy the garden and the mountain views from indoors.

Enclosure or screen room

Enclosing an existing covered porch or patio can give a vintage home a sheltered sitting room without changing its footprint much.

Pergola or patio cover

A pergola over a garden patio suits many older homes and provides shade while keeping the yard open.

What kinds of projects do Pasadena homeowners ask about?

The garden room

A glass room set among established plantings, used for reading, morning coffee or starting seeds. Light and the view come first, so the glass package gets most of the attention.

The quiet study

Many homes near Caltech, the hospitals and downtown offices belong to people who work from home part of the week. An insulated patio room with steady light and a door that closes makes a calm workspace.

The porch that finally gets used

Some older homes have a back porch that sits empty for much of the year because of heat, insects or winter chill. Enclosing it or replacing it with a real room brings it back into daily life.

The pool pavilion

On larger lots, a room or cover beside the pool gives shade, a place to change and a comfortable spot to keep an eye on swimmers.

Pasadena neighborhoods and lot types

Bungalow Heaven

A neighborhood of Craftsman bungalows on modest lots. Matching the architecture and keeping the addition in scale are the key considerations, and additional design review may apply to exterior changes.

Hastings Ranch

Post-war ranch homes on larger, level lots in the eastern part of the city, often with pools. Straightforward installations and larger rooms are common.

Linda Vista and the Arroyo

Hillside and canyon-edge homes with views, varied grade and mature trees. Site work and wind exposure get a close look.

Madison Heights and the south side

Stately older homes on generous lots with established gardens. Conservatory-style rooms and careful color matching are frequent requests.

Condos and townhomes

Attached homes may have small patios where an enclosure or cover is the practical choice, and association approval may be required.

Do you need a permit or HOA approval?

A room addition in Pasadena may require a permit from the City of Pasadena, and some covers and enclosures may as well. Homes in historic or landmark districts may also need design approval for exterior changes, and condominiums or planned developments may need association approval. The estimator can explain what is typically involved for your property.

How the free in-home estimate works

Estimates are free with no obligation, available 7 days a week from 9am to 9pm, and usually take about 15 to 40 minutes.

  1. The estimator looks at your home’s style, roofline, slab and the spot you have in mind.
  2. You discuss how the room will be used and which style suits the house.
  3. You review brochures and design layouts showing styles, glass, roofs, doors and colors.
  4. You receive estimates for the options you prefer and can ask every question.

Ways to save: financing and current specials

Special financing programs are available; see our financing page for details. For a limited time, current specials include savings on materials and rooms plus free factory room upgrades, which can help cover extras like upgraded glass.

Once you decide, preferred contractors complete the installation in days, not weeks. Every room carries a transferable lifetime factory warranty that carries over to the next owner if the home is sold.

Which option fits your Pasadena home?

For a traditional home with a garden, a conservatory-style or cathedral sunroom often feels most natural. For a comfortable everyday room through hot summers, choose an insulated patio room. For a lighter project, enclose a porch or add a pergola.
