Santee asks for a retaining-wall permit sooner than state code does — at 3 feet, or at any height within 5 feet of your property line. We design, permit and build block, concrete and stone walls that pass that checklist the first time, with a drain behind every one. Call for a free on-site estimate.

Santee walls by the numbers
Most California cities start from the model code, which exempts a retaining wall up to 4 feet measured from the bottom of the footing. Santee’s Engineering Department works from its own Form 019 instead, and it is stricter on every count: a permit at 3 feet measured from the top of the footing, and a permit for any retaining wall within 5 feet of a property line — which on a typical tract lot is most of the back yard. Hillside-overlay lots, geologic zones C and D and floodplain lots need one regardless.
The City also tells you how the wall must perform, not just when to permit it. Every retaining wall, “regardless of height,” has to be designed for earth and water pressure with a safety factor of 1.5 against tipping and sliding, built to the region’s standard drawings or an engineer’s design. More than half of Santee’s homes were built before 1980, so many of the walls we’re called to are decades old and leaning — and the replacement has to meet today’s checklist in full.
Retaining and freestanding walls, new and replacement. For the full build detail on each type, see our county-wide retaining wall and block wall pages.
Retaining
Grouted, steel-reinforced block on a keyed footing — drawn to the San Diego Regional Standard Drawings C-1 to C-8 where the wall fits them, or engineered where it doesn’t, with control joints laid out to Standard Drawing C-7.
Hillside lots
North- and west-side lots in the hillside overlay (HL, R-1 and R-1A zones) need a grading permit for any wall. We plan stepped terraces with the soils report the City will ask for on Friars Formation ground, and keep each tier’s backfill level so a short wall stays a short wall.
Property line
Leaning or cracked 1970s property-line walls taken down and rebuilt in grouted CMU on a proper footing — stucco, split-face or slump stone to match the street. A freestanding wall up to 6 feet, footing included, needs no building permit in Santee; we still confirm the line and height with Planning first.
Street frontage
Santee’s Ordinance No. 311 requires an anti-graffiti surface on any retaining wall visible from a public place. We specify one of the City-listed permanent coatings in the submittal, so it isn’t a correction notice later.
Stone
Dry-stacked or mortared fieldstone for low garden walls, and stone veneer over a reinforced block core where the wall is structural — the look of rock with a wall the inspector can sign off.
Wall + fence
Once a retaining wall stands more than 42 inches above the grade at its base, Santee requires a fence or safety rail at least 42 inches high on top. We design the footing and steel to carry it from the start, instead of bolting a fence onto a wall that wasn’t built for it.
Form 019 is unusually specific for a city handout. A wall must resist both the soil and the water behind it, with a minimum factor of safety of 1.5 against overturning and sliding. Walls that fit the region’s standard drawings can be built from them; anything taller, surcharged or outside their assumptions needs an engineer’s report, calculations and a soils report.
Our part of that is the drainage and the steel. Clean gravel backfill and a perforated pipe to daylight keep water pressure off the wall, which matters on Santee’s two kinds of ground: Friars claystone in the hills, which the City’s geotechnical study links to landslides, and San Diego River alluvium on the valley floor.
Santee splits wall permits between two counters. Engineering (619-258-4100 ext. 167) issues the retaining wall or grading permit when the wall is near a property line, 3 feet or taller, on a hillside-overlay lot or in a geologic, flood or open-space area. If none of that applies, the Building Division (ext. 155) still wants a permit for a wall that carries a surcharge or holds back sloping ground. Applications go through the City’s online portal with a plot plan drawn to engineer’s scale and a section through the wall.
Two details catch people out. If digging the footing means excavating on the neighbour’s side, the City’s sample plans show a signed letter of permission from that owner. And a retaining wall you can see from the street or a park needs an anti-graffiti finish. Since 2025, any job of $1,000 or more, or any job needing a permit, requires a licensed contractor.
Contractors who work mostly in other cities quote to the model code. Here is where Santee differs — and why a wall that would be permit-free elsewhere often isn’t here.
| California model code (CRC R105.2) | City of Santee | |
|---|---|---|
| Height exempt from permit | Up to 4 ft, unless surcharged | Under 3 ft, unless surcharged or near a property line |
| Measured from | Bottom of the footing | Top of the footing |
| Near a property line | No separate trigger | Permit at any height within 5 ft |
| Sloping backfill | Treated as surcharge | Building permit unless level ground behind equals wall height |
| Freestanding wall / fence | Exempt to 7 ft | Exempt to 6 ft, footing included |
| Street-visible retaining wall | — | Anti-graffiti surface (Ord. 311) |

Shaun measures heights, distances to the property line and to the house or driveway, and checks the zoning (hillside overlay or not) and geologic-zone maps for your parcel.
You get a plain answer: exempt, building permit, or Engineering retaining-wall or grading permit — and whether a soils report is likely on your ground.
Engineer’s-scale plot plan, wall section, standard drawing or engineered design, control joints and the anti-graffiti coating where needed, submitted through the City portal.
Underground Service Alert called two days ahead, footing excavated and keyed, steel set and inspected before the pour.
Reinforced block laid and grouted, waterproofing on the back face, gravel and perforated drain placed as the wall rises.
Cap, stucco, split-face or veneer finish, rail if the height calls for it, and final inspection sign-off.

Call (619) 581-2492Our 2026 county-wide ranges. In Santee the swing factor is the permit path: a standard-drawing wall is priced very differently from one that needs an engineer, a soils report and a grading permit.
| Wall type | Typical range |
|---|---|
| CMU retaining wall, standard, under 4 ft | $35–$60 per sq. face ft. |
| Engineered CMU retaining wall, 4–8 ft | $60–$140 per sq. face ft. |
| CMU retaining wall with stucco or stone veneer | $90–$220 per sq. face ft. |
| Natural stone retaining wall | $80–$250 per sq. face ft. |
| Stucco-finished block wall (freestanding) | $100–$200 per linear ft. |
| Block wall with stone or split-face veneer | $200–$400 per linear ft. |
Ranges for comparison, not a quote. Engineering, soils reports and City permit fees are separate lines on your written proposal.
The same 4-foot wall can be permit-light on one street and a grading-permit job on the next. What usually decides it, by part of town:
The Santee page covers the ground, permits and neighbourhoods across every kind of job. The county-wide pages go deeper on the build itself.
Straight answers before you hire. Anything else — call, and Shaun answers it himself.
Call (619) 581-2492Under 3 feet, measured from the top of the footing — and only if it is more than 5 feet from every property line, holds back level ground, carries no surcharge, and isn’t on a hillside-overlay, floodplain or geologic-zone C or D lot. Anything else needs a City permit (Form 019).
Usually because it is within 5 feet of a property line. Santee’s Engineering Department requires a retaining wall permit for any wall that close to the line, whatever its height. A hillside-overlay lot or sloping ground behind the wall will also trigger one.
Not a building permit if it is a freestanding wall no taller than 6 feet, measured from the bottom of the footing to the top. Santee still asks you to confirm the location and height with Planning and Padre Dam. If the wall also retains soil, the retaining-wall rules apply instead.
If it stands more than 42 inches above the ground at its base, yes — Santee requires a fence or safety rail at least 42 inches high on top. We design the footing and steel to carry it.
City Ordinance No. 311 requires retaining walls visible from any public place to have an anti-graffiti surface, and the City publishes a list of approved permanent coatings. We name the coating on the plans so it’s approved with the permit.
Not always. Walls that match the San Diego Regional Standard Drawings C-1 to C-8 can be built from them. Taller walls, surcharged walls, sloping backfill and difficult ground need an engineer’s design and a soils report. We tell you which after the site visit.
Standard CMU walls under 4 feet typically run $35–$60 per square foot of face; engineered 4–8 ft walls $60–$140. Engineering, soils and City fees are extra where required. You get an itemised written price after a free visit.
