About A Mountain

A Mountain is a little under nine-tenths of a square mile of Tucson's west side directly below Sentinel Peak, the hill the University of Arizona's students marked with an "A" in 1915. The neighborhood runs from Starr Pass Boulevard south to 36th Street and from Mission Road west to La Cholla Boulevard, and the peak's 372.8-acre city park begins just across Starr Pass Boulevard from its north-east corner. It is an older Tucson neighborhood where the newest houses set the top of the market: its streets were platted from the late 1930s, and a second wave of subdivision and building followed after 2000. All 39 Residential closings recorded inside this boundary over the three years to October 2026 were detached houses; there were no condominium or townhouse closings. They closed between $155,000 and $448,000, around a median of $299,000 and an average of $301,408, at a median $200 a square foot on a median 1,400 square feet. The build years in that record run from 1952 to 2025 to a median of 2005, and price follows them closely. The three closings under $200,000 were houses built between 1958 and 1979, at $155,000 to $176,000. The seven between $200,000 and $250,000 had a median build year of 1983, the ten between $250,000 and $300,000 one of 2003 and the ten between $300,000 and $350,000 one of 2005. All nine closings at $350,000 and above were built in 2006 or later, to a median build year of 2022, measured a median 2,240 square feet and closed at a median $410,000. At that top tier the price per square foot was still a median $200, the same as the whole record, so the newer houses here sold for their size rather than at a premium per foot. Compare a house here with sales of the same era, not with the neighborhood median. The median listing went under contract in 21 days, 33 once relists are counted, and the record closed at 100 cents on the list dollar; 15 of the 39 closed above their asking price and 14 took at least one price reduction. The range printed at the top of this page holds 36 of the 39 closings: the three older houses below $200,000 are outside it, and nothing closed above $450,000. Five further closings over the same three years were recorded as residential income property, at $390,000 to $420,000 and built from 2023 to 2025, and are not in these figures. These are closed sales, not homes currently for sale, and they are medians over a small group; a valuation still works from closely matched sales. The land record explains the two waves. Pima County counts 1,141 parcels wholly inside the line, every one carrying the county's TUCSON jurisdiction code, and 1,015 of them are zoned R-1, the City of Tucson's single-family zone; 114 are R-2, and the remaining 12 are C-1, C-2, R-3 and MH-1 along the arterial frontages. The 697 parcels under a single-family residential use code sit on a median lot of about 9,400 square feet, a little over a fifth of an acre. Twenty-five subdivision filings lie inside the boundary, and only one, Hiram Banks Acres of 1938, reaches past it. Sentinel Peak Acres came first, in November 1936, then Hiram Banks Acres in 1938, Vista del Pueblo in 1941, the 116-lot "A" Mountain Addition in February 1948, Vista del Pueblo Annex in 1949 and Plainview Heights in 1951. The 207-lot 36th & Mission filing followed in 1981, with Sentinel Villas and Sentinel Park in 1982, and the second wave was recorded from 1994: Casa Alegre, Casitas Alegres, Banks Grove, Regalo del Sol Estates and Hiram Banks Court, then the 114-lot Starr Pass Heights in December 2004, Sylvester Drive Estates in 2005 and small lot splits in 2021, 2023 and 2025. The county's legal description for the 33-acre Cholla High School parcel reads Vista del Pueblo No. 2, lots 1 through 140, a 1964 plat the school site now covers. Every edge checks against Pima County's own centrelines: Starr Pass Boulevard on the north, Mission Road on the east, 36th Street on the south and La Cholla Boulevard on the west. Inside the line is about 560 acres, and all 939 official address points inside it read ZIP code 85713. The whole boundary is inside the City of Tucson: annexation ordinance 2014, effective in March 1960, covers all 97 interior sample points with no deannexation. The City-registered A Mountain neighborhood association, registered in November 1984 and listed in Ward 1, is returned at all 97 points. A registered neighborhood association is a voluntary civic body and not a homeowners association. Starr Pass Heights and 36th & Mission each have recorded common-area parcels, and Pima County publishes no register of homeowners association dues, so whether a particular lot carries one, and what it costs, is answered by the title work and the resale disclosure, not by this page. Two of its neighbours have pages on this site: Menlo Park directly north across Starr Pass Boulevard and Westside Development west across La Cholla Boulevard. The Santa Cruz Southwest association to the east and the Enchanted Hills association to the south have no page here. San Juan Park, a 36.3-acre City of Tucson community park at 1665 South La Cholla Boulevard with a playground, ramadas, grills, a basketball court and horseshoe pits, lies wholly inside the boundary on its western side, and the City lists no restrooms there. Pima County maps a 75-foot regulated setback on San Juan Wash and another on Cholla Wash, the two named washes that cross the neighborhood, and records soil-cement bank protection on both; a handful of smaller, unnamed flow paths carry 25-foot setbacks. FEMA's flood map returns Zone X at 91 of the 97 interior sample points, Zone AH, a special flood hazard area for shallow flooding, at three in the northern half, and Zone AE, a special flood hazard area with base flood elevations, at three in the southern half. A setback is drawn from the mapped channel and not from a lot line, and a sample point is not a flood determination for any particular property, so check the flood map for a specific address. The Tucson Airport Authority's avigation easement and disclosure area for Tucson International reaches the south-east corner, ten of the 97 interior points, all near 36th Street and Mission Road. That is the ground over which the Authority asks for avigation easements and noise disclosure statements as a condition of new development and rezoning; it does not mean an easement is recorded against any particular parcel, and the title report is what answers that. Pima County's Davis-Monthan vicinity layers and the Marana airport overlays return nothing here. Measured from the middle of the boundary, John F. Kennedy Park at 3700 South Mission Road is about 1.4 miles south and Pima Community College's West Campus at 2202 West Anklam Road about 2.1 miles north. Schools are Tucson Unified throughout. Pima County's attendance-area layer returns Cholla High, at 2001 West Starr Pass Boulevard inside the boundary, at every sample point, and splits the lower grades along San Juan Trail: Tolson Elementary and Mansfeld Middle north of it, Oyama Elementary and Valencia Middle south of it. LiveBy's assignment query names the same five campuses. Assignments are drawn by address and change, so confirm a specific address with the district.
