Pasadena Is Not the City of Los Angeles, and Your Permit Proves It
Almost every remodeling guide written for this region assumes LADBS. Pasadena is its own city with its own building department, and that is not administrative trivia. It changes what you file, who reviews it, and how long you wait. Permits here come from the City of Pasadena Planning & Community Development Department through its Building & Safety Division, and the Permit Center works as a one-stop counter where the reviewing departments sit together. Los Angeles express-permit rules do not apply on this side of the line.

The Second Question: Is Your House in a Landmark District?
Pasadena holds one of the densest concentrations of protected residential architecture in Southern California, and the city takes it seriously. Design review and historic preservation both sit inside the Planning Division. If your property is individually designated or falls inside a landmark district, the city reviews exterior work against preservation standards instead of just checking it for code compliance.
That hits hardest on the parts of a remodel people assume are cosmetic. Windows are the usual collision. A like-for-like vinyl swap that would pass without comment somewhere else can get rejected on a contributing property. Roofing material, exterior cladding, porch details, even the extent of a repaint can come into review, depending on the designation.
None of that is a reason to avoid buying or remodeling a historic Pasadena house. It is a reason to settle the designation status before the design is fixed, so the scope gets drawn to what will actually be approved. If you own a designated property, look at the Mills Act too. It can change how the property is assessed for tax while you are doing the rehabilitation.
Designation Check First
We find out whether the property is designated or contributing before we draw anything, because that decides what the exterior scope can be.
Kitchens and Bathrooms
The two rooms with the most value per square foot and the most hidden complexity, in houses whose plumbing and wiring often predate current standards.
Structure In-House
Opening a plan in a 1920s Craftsman or a post-war ranch means a beam and a load path. Our engineering sits in the same office as the drawings.
Bathroom Remodeling in Pasadena
Around Los Angeles a typical bathroom remodel runs about $20,124, and most homeowners spend between $13,185 and $27,072. By scope: a minor remodel runs $5,274 to $19,488, a partial remodel $20,308 to $48,726, and a full remodel $51,685 to $153,203. Labor takes roughly 40 to 60 percent of the total, and homeowners here typically recoup around 65 to 70 percent at resale.
In Pasadena’s older houses, two things move the number more than the finishes do. The first is plumbing. Keep the fixtures where they are and the rough-in mostly disappears. Move the shower and you are trenching to reach the sewer at the right fall. The second is what the walls are hiding. Galvanized supply lines, cast iron waste, knob-and-tube remnants and ungrounded circuits all show up in houses this age, and once you find them you have to fix them.

Kitchen Remodeling in Pasadena
Historic Pasadena kitchens were built for a household that no longer exists. Closed off, service-oriented, cut off from the rooms families actually live in now. Opening them up is the change we get asked for most here, and it is also the one that most often turns a cosmetic project into a structural one.
A designated or contributing property adds a second layer. The interior may be free to change while the exterior is not, so any plan that leans on a new window or a moved door needs checking against the preservation standards before you commit to it. We cover the layout side in Pasadena kitchen remodeling layouts, and the broader question of updating a historic house without stripping its character in remodeling Pasadena’s historic homes.
Additions, and Building Up Instead of Out
When a Pasadena lot runs out of yard, you are choosing between a rear addition and a second story, and the foundation usually settles it rather than preference. A pre-war house on a raised foundation with cripple walls needs that whole system upgraded before it can carry another floor. A post-war slab may need cutting and new footings under the new bearing points. We lay out what really drives the number in second story addition cost, and the local version of the question in adding a second story in Pasadena.
Design, structural engineering and permitting sit in one team here, so the beam schedule and the drawings the city reviews are never two separate conversations. Our remodeling page shows how we run a project end to end, and our Pasadena architects page covers the wider work we do here.
