Building and remodeling in Catalina
Catalina is the small, rural community just north of Oro Valley along Oracle Road, with Catalina State Park to the south and mountain views in every direction. Most addresses are in the 85739 ZIP code. Much of its history traces to the Golder Ranch: Lloyd Golder III bought the Rail N Ranch in 1959, built the Golder Dam in the early 1960s for a lake community that was never completed, and developed subdivisions like Twin Lakes. The Golder Ranch Fire District still carries the name.
Catalina has stayed unincorporated with no plans to join a nearby town, and residents work to keep its rural character. Lots here are often an acre or more, horse properties are common, and the housing is a mix of manufactured homes, older site-built houses and newer construction, including a few production neighborhoods.
Who issues permits in Catalina
Catalina is unincorporated Pima County, so permits come from Pima County Development Services, not Oro Valley. That catches some people out, because Oro Valley is only a few minutes south. In the county, a detached casita is a guest house: one per lot, on a lot of at least 4,000 sq ft, a kitchen is allowed, it shares the main home's driveway and access, and it can't have its own utility meter.
What to check on a Catalina lot
- Septic. Most rural lots here are on septic. Adding a bedroom, suite or guest house can mean the system has to be checked or enlarged under Pima County's onsite wastewater rules.
- Washes. The Cañada del Oro and its side washes drain this area. Work in a regulatory floodplain or erosion hazard area in unincorporated Pima County generally needs a floodplain use permit first, including walls and fences.
- Manufactured homes. Additions to or beside a manufactured home can follow different rules than a site-built house. We confirm what applies before planning.
- Utilities and access. Distance from power, long driveways and caliche all affect cost. We walk the route utilities would take.
What Catalina owners call us for
Custom homes. An acre with Catalina Mountain views is a good place to build. We handle the whole build with our own crew on framing, structural work, stucco and roofing. See custom homes and our custom home cost guide.
Guest houses and additions. Larger lots leave room for a detached guest house for family or a mother-in-law suite. The casita cost guide covers the price drivers.
Decks, porches and covered patios. Outdoor space that faces the mountains and stands up to the sun. See decks and deck repair.
Roof and exterior repairs. Older shingle, tile and flat roofs, stucco cracks, rotted fascia and porch posts. See roofing, roof leak repair and stucco.
Many Catalina properties have been added to over the years: a carport enclosed here, a room added there, sometimes by a previous owner without a permit. Before planning new work, we look at what is already on the lot and how it was built. Older add-ons with undersized framing or roofs that tie in poorly are common leak and sag points, and it's usually better to deal with them as part of a new project than to build next to them. Our structural repair and framing crews handle that work directly.
Before monsoon season
Rural homes take the full force of summer storms. A roof check, clear drainage around the house and sealed stucco cracks before the monsoon, which in Arizona runs roughly mid-June through September, can prevent a lot of damage. Our monsoon prep guide has a simple checklist.
