The Tucson Subdivision Where a Carport Decides the History
San Rafael Estates, 69 Lusk-built Ranch houses off Broadway and Wilmot, joined the National Register in 2013. Why 13 of them no longer count.
The National Park Service approved refreshed documentation for San Rafael Estates on September 1, 2026. The file underneath it is one of the most specific descriptions of a 1950s Tucson street that exists.
On September 1, 2026 the National Park Service approved additional documentation for a pocket of east-central Tucson that most people only ever see from the Broadway side, as a wall. San Rafael Estates has been on the National Register since January 23, 2013, and the nomination behind it does something unusual: it counts the neighborhood house by house and says exactly which ones no longer qualify. Sixty-nine houses were built. Fifty-six of them contribute to the district. The thirteen that do not all lost their standing the same way, and the culprit is a feature almost nobody thinks of as architecture. It is the carport.

Sixty-Nine Houses, Three Models, Two Years
The subdivision was platted in 1954 and built out by 1956 by the Lusk Corporation, with Arthur H. Rader and Robert A. Little named alongside it as architect and builder on the nomination form. There are three models — the Lanai, the Monterrey, and one called Home for All America — and the original houses ran 1,600 to 1,900 square feet. Burnt adobe is the primary wall material almost everywhere, with red brick as a secondary. Roofs are pitched gable or shed forms with wide fascia boards, originally finished in gravel ballast that has since come off every one of them. Adobe chimneys, ribbon windows, window walls, sliding glass doors and wood clapboard recur throughout. The nomination is blunt about why three models do not read as three models: the variety of elevations and orientations gives each house a sense of individuality, so the street has cohesion without repetition. Lusk was, per the nomination, the only builder in the country to take the National Association of Home Builders Award of Merit five years running starting in 1954, four of those for Tucson projects, San Rafael among them.
A Street Plan That Turns Its Back on Broadway
The layout is the other half of what got the district listed, under Community Planning and Development. There are two entrances, one off Wilmot and one off Broadway, each marked by a low stuccoed wall with burnt adobe trim, integrated planters and the subdivision's name in wrought iron. One primary road curves between them; three secondary streets branch off it at T-intersections and dead-end in cul-de-sacs. Front façades face away from the arterials. Most streets run east-west, which is how a flat site keeps its view of the Santa Catalinas and how the houses keep the sun off their main windows. Alleys reach the back of every lot. There are no sidewalks, the curbs are rolled, and houses sit about forty feet back, centered on quarter-acre lots. Drainageways run the east, north and southwest edges as a landscaped buffer against the commercial development on the other side. The pool sits in the middle, next to two of the T-intersections, which puts more than half the houses within a block of it. At the time all this was built it was not even in the city — the area was unincorporated Pima County until Tucson annexed it in 1959.
The Carport Is the Test
Every house here was built with an integrated carport for one or two cars, and the nomination treats it as a load-bearing part of the design rather than a place to park: the carport is what gives the façade its depth. That is why enclosing one is the most consequential thing an owner of one of these houses can do. All thirteen non-contributing residences were reclassified for lost architectural integrity, and the nomination names carport enclosure — into a garage, or into interior living space — as the most common alteration in the subdivision. The call is not arbitrary. The form applies the Arizona State Historic Preservation Office's revised policy statement of March 25, 2011, which asks whether an infill happened inside the period of significance, whether the infill is itself significant, and whether it meets the Secretary of the Interior's Standards — chiefly whether it destroyed the character-defining features of the original building, the carport included.
What an Owner Actually Gets Out of This
Two practical things. The first is that the nomination is a free, unusually detailed description of a specific house type — setbacks, materials, roof forms, window types, what the original landscaping looked like and why the front yards are gravel — which is the document to read before quoting a remodel on a house of this vintage, here or in any of Tucson's other post-war districts. The second is that contributing status is a per-parcel fact, not a neighborhood one, and it is not fixed forever: a house that lost it can, in principle, regain it if what was done is undone. Whether a given address contributes, and what the City of Tucson's own historic preservation rules require of it, is a question for the city's historic preservation office rather than for a listing sheet. San Rafael was not the only Tucson district to clear the Park Service that week in 2013, either — Rincon Heights was listed the very same day.
