Building or remodeling in Cave Creek: native plants, grading, and wash rules

Your vision, your home, our expertise.

In most of Cave Creek's Desert Rural zones, the first 12 feet inside every property line has to stay natural desert. You can cross it with a driveway and utility lines, and that is about it. That one rule, from Chapter 6 of the Town's zoning ordinance, surprises a lot of buyers who plan to add a pool, a garage, or a casita after closing. It is one of several Town rules on native plants, grading, and washes that shape what you can actually build on a Cave Creek lot.

The short answer Before you grade, clear, or build anything in Cave Creek, you need a Zoning Clearance and Building Permit, and most projects also need a Native Plant Inventory Plan and Landscape Plan. Saguaros over 4 feet tall cannot be removed or moved without Town approval, major washes stay in their natural condition, and lots with natural slopes of 15% or more are treated as hillside. Check these rules before you write an offer, not after.

What the Town's rules say

  • Natural buffer in DR zones: the area within 12 feet of any property line stays natural and undisturbed, except for driveway and utility access (Town of Cave Creek Zoning Ordinance, Chapter 6, Section 6.0, effective Dec 22, 2011)
  • Native plants near lot lines: in DR zones, no native plants within 12 feet of a property line may be removed or relocated, except for driveway and utility access (Chapter 8, Section 8.1 F, effective Dec 22, 2011)
  • Saguaros: removing or relocating a saguaro taller than 4 feet requires a Zoning Clearance (Chapter 8, Section 8.1 C)
  • Cactus salvage inventory: required for all saguaro, barrel, hedgehog, ocotillo, and buckhorn cholla inside the area of disturbance, submitted with building plan review (Chapter 8, Section 8.1 B)
  • Hillside: any lot or parcel where the natural terrain has a slope of 15% or greater; steep slopes are 20% or more (Technical Design Guideline No. 1, Grading and Drainage, Section 1.4, accepted Oct 15, 2007)
  • Major washes: a wash in a FEMA floodplain or with a 100 year peak flow of 50 cubic feet per second or more (Guideline No. 1, Section 1.4); the 100 year floodplain and erosion setback of a major wash stays in its natural condition (Chapter 10, Section 10.1 G)

Why these rules matter to a buyer

Cave Creek's ordinance is built around keeping as much desert intact as possible. Chapter 8 says site design shall provide for the maximum possible undisturbed area on the site, and it calls out washes, riparian areas, rock outcroppings, mesquite bosque, and saguaro stands for special care. In practice, that means the buildable part of a lot can be much smaller than the lot itself.

Take a one acre lot that looks wide open on a listing map. Subtract the 12 foot natural strip along every lot line. Then subtract any wash corridor, which for a major wash is set by an engineer's 100 year floodplain and erosion setback study rather than a fixed distance. Then work around saguaros you would rather not relocate. The space left for a house, a pool, and a garage can shrink fast.

Paperwork is the other surprise. Chapter 6 requires a grading and drainage plan and drainage report prepared by an Arizona registered civil engineer and approved by the Town Engineer before a permit is issued. A dust control permit comes first. On a hillside lot, the Town also requires financial assurance before any grading or grubbing, and it can use those funds to restore the site if the work does not follow the approved plan.

Washes need their own analysis

Washes are common in Cave Creek, and the Town treats them seriously. Chapter 10 says no disturbance is allowed beyond approved non disturbance boundaries during or after construction, and those boundaries must be staked and fenced. A minor wash can sometimes be rerouted on site, but only with approval from the Flood Control District of Maricopa County and the Town Engineer, and the new channel must carry the 100 year flow with at least one foot of freeboard. Grading must also keep historical drainage at the property boundaries, including where water leaves the parcel and how fast.

Outdoor lighting is part of the design

The Town lists its dark night sky among the things buyers should know about. Its outdoor lighting page says fixtures must be fully shielded and cast downward so the bulb is not visible from an adjacent street or property. Clear glass coach lights are not allowed unless the glass is frosted, wall mounted fixtures top out at 10 feet, dusk to dawn lights are prohibited, and the only security lights allowed are fully shielded, downward, motion sensor fixtures.

How to plan a build or remodel in Cave Creek

  • Walk the lot with the rules in hand. Note where the property lines run, where water flows, and where the larger saguaros stand. A survey that shows lot lines and topography makes this far easier.
  • Ask whether the parcel is hillside. If natural slopes reach 15%, expect engineering, financial assurance, and closer review.
  • Check for mapped washes and floodplains. Look at the FEMA flood map and ask the Town about any wash on or next to the lot. A wash can decide where the house goes.
  • Budget for consultants. Plan on a civil engineer for grading and drainage, and on a native plant inventory before plan review. Get quotes during your inspection period if you plan to build.
  • Call the Town early. Town staff can confirm the zone, the current rules, and which permits apply. The Town's main number is 480.488.1400.
  • Plan lighting with the house. Choosing shielded fixtures during design costs less than replacing noncompliant ones later.

Avoid this mistake: clearing brush, moving a cactus, or grading a pad before you have a permit. Chapter 8 allows fines to the maximum extent allowed by law for salvage, grubbing, or grading without a permit, and Chapter 10 requires land disturbed in violation to be regraded to its original contours and revegetated with the same species, size, and density. That is an expensive way to start.

The honest caveats

The ordinance chapters cited here carry effective dates from 2011, and the grading guideline was accepted in 2007. They were the versions posted on the Town's website when we checked, but codes change, so confirm current rules with the Town before you rely on them. The two Town sources also differ on timing: Chapter 6 says to post the permit 48 hours before grading starts, while Guideline No. 1 says 96 hours. The ordinance says the more restrictive rule applies, so ask the Town which one it enforces.

We have not covered every requirement. The protected native plant list and size thresholds sit in Technical Design Guideline No. 4, and zone specific limits such as building height and lot disturbance percentages sit in the residential zoning chapter. Subdivisions and HOAs can add their own rules on top of the Town's. Every lot is different, so treat this as a starting checklist, not a site plan.

Frequently asked questions

Do I need a permit to clear brush or grade my lot in Cave Creek?

Yes. Chapter 6 of the Town's zoning ordinance requires a Zoning Clearance and Building Permit before any grading or grubbing on a lot or parcel in any zone. Chapter 8 also requires a Building Permit before plant salvage, grubbing, site grading, or landscape improvements.

Can I remove a saguaro on my Cave Creek property?

Removing or relocating a saguaro taller than 4 feet requires a Zoning Clearance from the Town. Saguaros, barrel, hedgehog, ocotillo, and buckhorn cholla inside the area of disturbance must also appear on a salvage inventory submitted with building plan review.

What counts as a hillside lot in Cave Creek?

The Town's Grading and Drainage guideline defines hillside as any lot or parcel where the natural desert terrain has a slope of 15% or greater. Hillside lots require financial assurance before grading or grubbing, and slopes of 20% or more are treated as steep slopes.

Can I build close to a wash in Cave Creek?

It depends on the wash. The 100 year floodplain and erosion setback of a major wash must stay in its natural condition, except for necessary roads, driveways, and utility easements, and an Arizona registered civil engineer sets that setback through a study. A minor wash may be rerouted on site only with approval from the Maricopa County Flood Control District and the Town Engineer.

What are Cave Creek's outdoor lighting rules?

The Town says outdoor lighting must be fully shielded and cast downward so the bulb is not visible from an adjacent street or property. Wall mounted fixtures can be no higher than 10 feet, dusk to dawn lights are prohibited, and security lighting must be fully shielded, downward, motion sensor fixtures.

The bottom line

A Cave Creek lot comes with rules that protect its desert, washes, and night sky, and those rules decide where a house, pool, or addition can go. The 12 foot natural strip in DR zones, the 4 foot saguaro threshold, the 15% hillside line, and wash setbacks set by an engineer are the ones that most often change a buyer's plans. If you plan to build or remodel, confirm the current rules with the Town and line up a civil engineer before your inspection period ends.
