Tanque Verde is unincorporated Pima County on Tucson's east side, permitted through Pima County Development Services. Lots are large, many properties keep horses or livestock, and septic systems are common. Valdez Custom Builders (Arizona ROC 341570) builds guest houses, barns, shops, and additions throughout the area. Call (520) 909-0866.
Permitting and zoning in Tanque Verde
Tanque Verde is unincorporated county land, so permits come from Pima County rather than the City of Tucson. As with the Foothills, the Tucson mailing address misleads a lot of homeowners about which authority governs their property.
County zoning on these larger parcels is comparatively accommodating toward detached accessory structures, which is why barns, shops, and guest quarters are so much more achievable here than on a city lot. Setbacks are generous relative to lot size, and lot coverage is rarely the binding constraint.
What does constrain projects is water. The Tanque Verde Wash and its tributaries run through this area, and washes carry drainage and floodplain implications that affect where a structure can go and how its foundation must be designed. Regulatory floodplain aside, building in a path where water moves during monsoon is a bad idea regardless of what a permit allows. We map drainage during site analysis.
Septic capacity and well status apply here as they do in Vail. Adding a dwelling unit to a septic served property may require capacity review, and properties on private wells need honest evaluation of yield before adding demand.
The homes we work on in Tanque Verde
Tanque Verde housing runs from midcentury ranch homes on multiple acres through recent custom construction, with a substantial share of properties set up for horses. Many parcels carry a house plus some combination of barn, arena, tack room, shop, and equipment storage, and those outbuildings are a real part of the property's function rather than an afterthought.
Equestrian work is a genuine specialty within what we do. The horse barn shown above illustrates the approach: proper ventilation, which matters enormously in this climate, a roof assembly that handles both heat load and monsoon, cupolas that do real ventilation work rather than serving only as decoration, and a structure detailed to last decades in desert conditions. Stall barns, run in sheds, tack and feed rooms, wash racks, and covered arenas all require particular knowledge, and a contractor who has only built houses tends to get the ventilation and drainage wrong.
Guest houses and casitas are the other major category. These properties have the space for a properly separated detached unit, and the usual purpose is family: adult children, aging parents, or long staying visitors. Because the parcels are large, placement can prioritize privacy, view, and orientation rather than fitting into the only available corner.
Mature vegetation is a defining feature. Established mesquite and other desert trees are a large part of why these properties feel the way they do, and protecting root zones during construction requires actual planning around equipment routing and material staging.
Site conditions that shape a project here
| Condition | What it means for your build |
|---|---|
| Pima County jurisdiction | Unincorporated land permitted through Pima County despite Tucson mailing addresses |
| Washes and drainage | Tanque Verde Wash and tributaries affect buildable area and foundation design |
| Septic systems | Common on these parcels, and adding a dwelling may require capacity review |
| Large lots | Coverage is rarely the binding constraint, so placement becomes a genuine design decision |
| Mature vegetation | Established desert trees require root zone protection and planned equipment routing |
| Livestock operations | Construction sequencing has to account for animals remaining on the property throughout |
What we build in Tanque Verde
ADUs and guest homes in Tanque Verde
Tanque Verde parcels are large enough to place a guest house properly, with real separation and its own orientation. Septic capacity is typically the first thing we evaluate.
Kitchen and bath remodeling in Tanque Verde
Remodels on midcentury ranch homes and newer custom construction. Older homes on these properties sometimes carry undocumented modifications worth investigating before scope is set.
Home additions in Tanque Verde
Additions where lot coverage is not the limiting factor, so design can respond to view, orientation, and how the property is actually used.
Outdoor living in Tanque Verde
Barns, stalls, tack and feed rooms, wash racks, shops, and covered work areas. Ventilation and drainage are where equestrian structures succeed or fail in this climate.
Neighborhoods and developments in Tanque Verde
We work throughout the Tanque Verde Valley, Forty Niner Country Club Estates, Agua Caliente, and the horse properties toward Redington Pass.
Much of this area carries SR, or Suburban Ranch, zoning with parcels running from one to five-plus acres. That is why detached barns, shops, and guest quarters are so much more feasible here than on a city lot, and why 1970s slump-block ranch homes are a common starting point.

Frequently asked questions
Is Tanque Verde part of the City of Tucson?
No. Tanque Verde is unincorporated Pima County, and permits are issued by Pima County Development Services rather than the City of Tucson. Tucson mailing addresses in this area do not indicate city jurisdiction.
Do you build horse barns and equestrian structures?
Yes. Stall barns, run in sheds, tack and feed rooms, wash racks, and covered work areas are a regular part of our Tanque Verde work. Ventilation and drainage are the details that determine whether an equestrian structure performs well in this climate, and they are where inexperienced builders most often fall short.
How do washes affect building on my property?
The Tanque Verde Wash and its tributaries carry drainage and potential floodplain implications that can affect where a structure may be placed and how its foundation must be designed. Beyond regulation, building in a path where water moves during monsoon is inadvisable regardless of permitting. We map drainage during site analysis.
Can I build a guest house on my Tanque Verde property?
Usually yes. These parcels are typically large enough that lot coverage is not the constraint, and county zoning is comparatively accommodating toward detached structures. The practical limits are septic capacity, water source, and utility distance, which we evaluate during the consultation.
