Common rejection reasons

AI-researched, not yet verified

The most frequent reasons Oncor or DeSoto kicks back a residential solar permit. Avoid these on your first submittal to skip a 7–14 day correction cycle.

  • AHJ rejects Electrical Permit application if electrical subcontractor is not registered with City of DeSoto (annual state-licensed trade registration requirement)
  • SLD is missing required VLLD overlay showing Oncor utility meter interface; Oncor eTRACK will not advance application without this separate diagram per May 2025 Residential/Small Commercial Requirements
  • Structural/wind uplift letter is not PE-stamped by Texas-licensed professional engineer or does not reference ASCE 7 load calculations for Dallas County 115 mph design wind speed; DeSoto enforces IBC 2021 compliance
  • Equipment specification sheets (PV modules, inverter, AC disconnect) do not match make/model/quantity listed on SLD; Oncor flags mismatch as hold reason in eTRACK portal
  • Contractor Registration & Subcontractor Validation Form is submitted via email instead of through CSS Portal (https://cityofdesototx-energovweb.tylerhost.net/apps/selfservice#/home); DeSoto no longer accepts email submissions as of September 5, 2025
  • Inverter lacks UL-1741 Utility Interactive certification or IEEE 1547-2018 compliance documentation; system is reclassified as non-certified and requires separate Oncor non-certified application form + witness testing
  • Certificate of Insurance (ACORD 25) does not list Oncor Electric Delivery Company as additional insured or has lapsed coverage; Oncor will not execute Interconnection Agreement without current certificate
  • HOA approval letter (or written non-restriction statement per TX Property Code §202.010 / TX HB 431) is missing from AHJ permit package; DeSoto may not explicitly require it but absence creates downstream delays if HOA challenges installation mid-permit

How long does it take to get a solar permit in DeSoto, TX?

DeSoto's plan-desk averages about 15 days from submittal to permit issuance. From first submission to PTO (utility approval), the typical residential install runs about 60 days — AI-researched, not yet verified.

Where do I submit a solar permit in DeSoto?

DeSoto accepts solar permit applications through its online permitting portal. Portal: https://cityofdesototx-energovweb.tylerhost.net/apps/selfservice#/home. Plan-desk contact: buildinginspections@desototexas.gov.

Which utility handles interconnection in DeSoto?

Oncor is the utility TexPTO lists for DeSoto, but other utilities may serve parts of the area — for a specific address, confirm the utility with your meter or a recent bill (the utility is the company that delivers power to this address, which may not be the one that bills you). Residential solar systems typically need both a permit from the permitting authority (where one is required) AND an interconnection agreement from the serving utility before the utility grants Permission to Operate (PTO).
