Permits and Title 24
Mechanical permits come from Imperial County Planning & Development Services (ICPDS) or your city's Building & Safety division. The County's Civic Access online portal is live at icpds.com.
| Requirement | Details |
|---|---|
| Permit office | ICPDS (El Centro) for unincorporated areas; city Building & Safety inside city limits. El Centro city submittals are still paper-based. |
| Sizing audits | Manual J load calculations are mandatory and strictly audited - sizing must account for extreme 115-degree summer conditions. |
| Title 24 registry | All CF1R compliance forms must be registered through the CHEERS registry. |
| Refrigerant charge | Refrigerant Charge Verification by a certified HERS/ECC rater is mandatory in Climate Zone 15 (the Imperial Valley). |
IID electric rates and programs
Imperial Irrigation District (IID) is the local utility - not SCE or SDG&E. Its rates are lower than the coastal utilities, but summer cooling is still 75-80% of a valley electric bill.
Base rate
IID's consolidated residential base runs around 22 cents per kWh with a fixed monthly customer charge. Current numbers are always on IID's rates page at iid.com.
Shift & Save
IID's time-of-use program puts the summer peak at 4-9 PM weekdays. IID has offered a $250 enrollment incentive for customers who shift usage off-peak - check iid.com for the current offer.
Summer bill credit
IID's board approved a direct summer bill credit on energy used June through September 2026 - 12% off qualifying consumption. Confirm the current program with IID.
Rates and programs change. We link IID's own pages rather than promise numbers - iid.com/power/rates-regulations/rates.

Desert-specific care
Valley systems live on silt, UV, and 115-degree afternoons. The short version: rinse condenser coils monthly in summer, test the capacitor every spring, protect line insulation from sun, and change filters on a desert schedule. The full routine is in our desert maintenance guide, and the highest-value DIY skill is in the capacitor guide.
