Santee, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Santee Municipal Code Section 13.10.040(C) adopts Table 13.10.040A, 'Basic Development Standards - Residential,' as the minimum development standards for every residential district, and item 5 of that table is Maximum Lot Coverage. The table runs the eight residential zones side by side: HL at 25 percent, R-1 at 30 percent, R-1A at 35 percent, R-2 at 40 percent, R-7 at 55 percent, R-14 at 60 percent, R-22 at 70 percent and R-30 at 75 percent. The same section states that private deed restrictions can't permit a lesser standard where the code sets a minimum, and can't permit a greater standard where the code sets a maximum, so an HOA's CC&Rs can't waive the 25 percent cap in HL even if a homeowner wants to build more.

Section 13.10.040(A) makes clear these figures apply citywide to residential development and aren't superseded by private covenants running the other direction. For accessory dwelling units, Section 13.10.045(G)(3) cross-references this same lot coverage table and bars an ADU from pushing a lot's total coverage over the zone's maximum, though it also guarantees an ADU can't be forced below 800 square feet purely because of a lot coverage limit. Planned Residential Developments in the R-7 and R-14 zones get their own coverage figures under Table 13.10.040E: 55 percent in R-7 and 60 percent in R-14, matching the base table for those two zones.
