A four season sunroom is a fully insulated, climate-controlled room addition you can use on the hottest day in August and the coldest night in January.
Four season sunrooms in Burbank, CA are fully enclosed room additions with insulated walls, proper roofing, and a dedicated heating and cooling system - built to the same standard as the rest of your house. Most projects take four to eight weeks to build once permits are approved, and the finished room works as a true year-round living space. BSP Burbank Sunrooms and Patios handles design, permitting, and construction from start to finish.
If you want a room that feels exactly like the rest of your home, a four season build is the right direction. If you are weighing a lower-cost option for milder use, see our three season sunrooms page for a side-by-side comparison. If you are looking for a similar but slightly different framing, all season rooms cover the same climate range with a few design differences worth reviewing.
California's energy efficiency requirements apply to new room additions, which means the glass, insulation, and HVAC equipment in a four season sunroom must meet state standards. In practice, that translates to a room that is more comfortable and costs less to heat and cool over time.
If Burbank's Valley heat drives you inside every time you try to enjoy your backyard, your current outdoor setup is not working. A four season sunroom gives you a fully climate-controlled room you can sit in at noon in August - not a covered patio that just blocks the direct sun.
A patio cover or pergola blocks direct sunlight but does not seal out heat, cold, or wind. If you have already added fans and space heaters and still find the space uncomfortable, the underlying problem is that it is not truly enclosed. A four season sunroom solves that permanently.
Adding a four season sunroom is one of the few ways to gain a full, livable room without the cost and disruption of moving. Many Burbank homeowners use the room as a home office, a second living area, or a playroom that takes daily pressure off the rest of the house.
An existing patio slab in good condition can significantly reduce the foundation cost of a four season sunroom. If you have been wondering whether that slab could become something more useful, a contractor visit will tell you quickly whether it is a good candidate.
Four season sunrooms are not one-size-fits-all. The design depends on how you plan to use the room, your property's footprint, and your home's architectural style. We build compact single-purpose rooms as well as large open extensions that flow naturally from the main living area.
Every build uses insulated glass panels rated for Southern California heat and a dedicated heating and cooling source for the room. Whether you connect to your existing HVAC system or install a separate mini-split, we size the system based on the room's square footage and the direction it faces - both matter significantly in Burbank. The U.S. Department of Energy has useful guidance on mini-split systems if you want to understand how they compare to ducted options.
Compact, single-purpose space for a home office, reading room, or hobby area that connects to the backyard.
Larger open footprint that flows naturally from the main living area, adding functional square footage to the home.
Oriented for natural light and indoor-outdoor access, designed for everyday meals and entertaining.
Designed from scratch for complex lot shapes, architectural requirements, or clients with specific material preferences.
Burbank sits in the San Fernando Valley, where summer temperatures regularly push into the 90s and the sun is intense for most of the year. Glass selection is the single most important decision in a four season sunroom design here, and a contractor who knows the Valley will steer you toward panels with a lower solar heat gain rating - meaning less of the sun's heat passes through the glass into the room. Homeowners across the valley, from Burbank to El Monte, face the same challenge, and we build across the entire service area.
Burbank also has its own city permit process, separate from Los Angeles County, and many of the city's homes were built in the postwar decades when electrical panels were sized for far smaller loads. We assess the panel during the estimate visit and flag any upgrades needed before you sign. California's energy standards for new room additions also push glass and insulation requirements higher than most other states - which is actually good news, since it means a more comfortable, efficient room long term. The California Energy Commission publishes the current building energy efficiency standards if you want the full picture.

We measure the space, review the foundation, and assess your existing electrical panel. You receive a written estimate that covers all work, with no line items added later.
We submit permit drawings to the City of Burbank and handle any HOA architectural review. We prepare the site and foundation while permits are processing, so construction starts as soon as approvals land.
We frame the room, install insulated glass, run electrical, and set up your heating and cooling. City inspectors verify the work at key stages before the final walkthrough with you.
We respond within 1 business day. No obligation after the estimate. When you submit, someone from our office will call to schedule a free on-site visit and walk through your options.
(747) 291-7068We specify glass with a low solar heat gain coefficient on every four season build so the room stays comfortable in August without running the air conditioner constantly. This is not optional in the San Fernando Valley.
We handle the full permit application, plan submission, and inspection scheduling with the City of Burbank Building Division, including HOA architectural review if your neighborhood requires it.
California's energy efficiency requirements for new room additions are among the strictest in the country. We build to those standards, which means a room that is cheaper to heat and cool over time.
Before a single shovel moves, you have a written timeline showing permit review, site prep, construction phases, and final inspection. No surprises, no mid-project schedule changes without notice.
Every four season sunroom we build in Burbank is permitted, insulated to California energy standards, and inspected by the city at multiple stages. That documentation matters - for your insurance, for your appraisal, and for a smooth sale when the time comes. The National Association of the Remodeling Industry recommends verifying that your contractor carries the required licenses and insurance and that all work is inspected before final payment.
A lower-cost option for mild climates where full year-round temperature control is less critical.
