City of Pasadena
Pasadena Doesn’t
Negotiate on Detail
Pasadena’s Design Commission and Historic Preservation Commission review residential projects with rigor that catches firms unfamiliar with the city off guard. Eave depths, window mullion proportions, trim profiles, material grades, paint sheens, and roof pitches all get asked about. We work in Pasadena because we are based here, and because the way we draw is the way the city expects work to be drawn.

The Problem
Pasadena Reviews the Details.
Pasadena protects its architectural heritage more rigorously than most California cities. The Design Commission, the Historic Preservation Commission, and the city’s landmark district frameworks are not ceremonial. They review actual decisions about actual buildings — and the questions they ask are detailed enough that generalist designers regularly fail to answer them on the first round.
What gets asked: What is the roof pitch on the existing structure, and does the addition match it? How deep is the existing eave overhang, and why is the proposed eave shallower? What is the muntin profile of the original windows, and why does the proposed window package use a flat aluminum muntin instead? Why is the proposed siding exposure 6 inches when the existing exposure is 4-and-three-quarters? These are not nitpicks. They are the work. They define whether a project reads as part of the original house or as an attachment from a different building.
Firms that arrive at a Pasadena hearing without these answers do not move forward. Firms that arrive with them tend to. The difference is preparation, not luck.
How We Approach It
Restraint, Subordination, Documentation
Pasadena work asks for three things consistently: restraint in the design moves, subordination of the addition to the original house, and documentation that gives the commission what it needs to evaluate the proposal. We design and document with all three in mind from the first sketch.
01
Match the Original’s Discipline
Period homes were designed with consistent rules — eave depth, window rhythm, wall proportion, trim grammar. Successful additions extend those rules. They do not improvise around them.
02
Subordinate, Don’t Compete
An addition that visually competes with the original house is the addition that fails review. We mass, locate, and detail additions to read as supporting work, not as a second house.
03
Draw to the Question
Sheets, callouts, elevations, and material schedules are organized to answer the questions Pasadena commissioners actually ask. The plan set should make their job easier, not harder.
Real Projects
Older Homes, Careful Additions
The Pasadena and broader San Gabriel Valley historic context is where we operate every week. The discipline that survives review here is the same discipline that produces good work everywhere — but the bar is higher and the review is closer.
365 Toyon Road — Residential Addition
An active addition project in adjacent Sierra Madre, currently moving through city design review. Multi-zone HVAC integration, basement laundry, bathroom revisions — all integrated into a residential addition in a city that takes its character seriously.
Spanish Revival, Craftsman, Mid-Century, Modern
Pasadena’s landmark districts span multiple contributing periods. We work across the styles that show up in this city — not from a default visual preference, but from the period the original house actually represents.
What This Page Does Not Promise
Some Pasadena Additions Shouldn’t Be Made at All.
Honest Counsel
If a proposed addition can’t be made compatible with the existing house, the answer is not better drawing. The answer is a different scope, a different location, or a different project.
We have advised Pasadena owners against additions we could have been paid to draw. When the original house is too constrained, when the contributing period rules out the proposed massing, when the lot doesn’t support the program — we say so. The owner gets the analysis. They keep the money they would have spent on a plan set that was never going to be approved.
Pasadena rewards projects that respect the original. It penalizes projects that don’t. We try to make sure the owner only commits to projects that fall in the first category.
