Adding an ADU in Sedco Hills

Named for the South Elsinore Development Company, Sedco Hills is semi-rural with a genuinely mixed build era — a 1970s-to-1990s core with newer construction layered in.

The older section is the stronger ADU candidate, and because most of this housing stock was permitted before Wildomar incorporated in 2008, the original approvals are county records rather than city ones.

We publish only what we verified. Lot dimensions vary enough inside a single tract that a neighborhood average would mislead you, so the tool reads your own parcel instead.

Why two Sedco Hills lots the same size answer differently

Both of these are 7,200 sq ft with the same 40 × 46 ft house, under Wildomar's rules. The only difference is the shape, and it changes the answer.

Two made-up lots, but not made-up numbers: the green area, the fit verdicts and the plan counts are computed with Wildomar's own 4 ft setback and 10 ft separation by the same functions the lot tool runs on a real parcel. Your lot is not either of these, which is the point — we read yours.

Measure my actual lot

Honest limits

What the geometry check can and cannot tell you

Why three answers, not yes or no

  • Public parcel lines sit 3 to 25 ft from the surveyed boundary.
  • The setback being measured is only 4 ft.
  • When the error bar is wider than the measurement, "yes" is a guess. So: Fits Tight Unlikely

What public data cannot see

  • Easements through the rear yard
  • Slope
  • Sewer or septic capacity
  • Electrical panel capacity
  • Soil conditions

Any one of these can stop a project that passes the geometry check.

On a tight lot, studio needs about 29 by 17 ft of clear space — and staying under 750 sq ft waives impact fees entirely.
