The county map separates city limits from ETJ clues.
Collin County's engineering FAQ sends users to the county interactive map to locate a parcel, identify unincorporated areas and turn on the ETJ Boundary layer under Boundaries.
Read the source ->Jamie Ellis' ETJ and permit handoff
Send ETJ, city-limit and permit clues before they stall a file.
For builders, developers, lenders, agents and attorneys: collect the Collin County map, ETJ, OSSF, permit, plat, survey or commitment source and one process question without asking the public form to decide jurisdiction, zoning, approval, title or legal effect.
Audience and job
Built for acreage, builder and permit-sensitive packets.
A builder, developer, lender, commercial agent or attorney may see a city-limit clue, ETJ boundary, OSSF question, permit record, plat note, survey callout or commitment item before the file is ready for a decision. This handoff keeps the first packet source-forward: public source, jurisdictional lane, timing pressure and one next title or escrow process question.
The useful source packet
Send the source that raised the ETJ or permit question and label what kind of file condition it created. WG Title can route the title and escrow process question; city, county, health, engineering, underwriting and legal conclusions stay with the right reviewer.
Current source check
ETJ and permit sources help when each lane stays labeled.
These public sources were checked on September 1, 2026. They help a transaction professional organize a better first packet, but they do not decide city jurisdiction, ETJ status, zoning, subdivision compliance, platting authority, permit sufficiency, OSSF approval, title status, underwriting, legal effect or closing timing.
ETJ platting questions have a city lane and an OSSF lane.
The FAQ says ETJ parcels generally follow the city ETJ subdivision lane, while an OSSF Suitability Subdivision Review for the plat still routes through Collin County Development Services.
Read the source ->Land-division packets should name the ETJ source early.
The county land-division page tells developers in a municipal ETJ to contact that city for platting information and notes that ETJ parcels served by individual OSSF need county OSSF suitability review prior to any city plat review.
Read the source ->OSSF routing depends on the permitting authority.
The development-services FAQ says outside-city-limit properties apply through the Collin County CSS portal, inside-city-limit properties may also need a county OSSF permit, and TCEQ keeps the local-authority lookup.
Read the source ->The OSSF plat review has its own clock and attachment path.
For an OSSF Suitability for Plat Review, the FAQ says applicants use the CSS portal, check whether the parent tract is unincorporated, city-limits or ETJ, allow 2-4 business days for invoice intake and plan for a review that can take up to 45 days.
Read the source ->Permit records belong in the public portal lane.
Development Services points permit applicants to Citizen Self-Service and keeps its permit-fee and department contact material on the public county site.
Read the source ->TCEQ keeps the statewide OSSF authority source.
TCEQ's OSSF homeowner page links readers to find their permitting authority and current OSSF rules, which helps keep county and city source questions out of guesswork.
Read the source ->This is public education, not a referral benefit.
TDI's P-53 framework prohibits rebates, discounts and other things of value tied to solicitation or referral of title-insurance business. This page is available on the same terms to everyone.
Read the source ->What to send
Give the closer a packet that separates map clues from conclusions.
The best ETJ and permit handoff is not a zoning answer, permit opinion, title opinion or legal conclusion. It tells the team what source exists, what file condition raised the issue and who needs the next answer.
- Property address, county, city or ETJ clue, parcel or Property ID, subdivision name, acreage or lot-count clue, map layer used and target timing
- Map lane: Collin County interactive-map link or screenshot reference, city-limit clue, ETJ Boundary layer clue and date checked
- Platting lane: city ETJ contact, county land-division source, subdivision-regulation question, plat package status and any city or county reviewer already contacted
- OSSF lane: permitting authority source, CSS application or OSSF Suitability for Plat Review status, invoice or review stage and missing attachment note
- Title packet lane: commitment or GF number, Schedule B or C item number, survey, deed, plat, lender condition, attorney note and one process question
What to avoid
Keep city, county, health and legal conclusions out of the first note.
- Do not use the public form to decide city jurisdiction, ETJ status, zoning, subdivision compliance, platting authority, permit sufficiency, OSSF approval, title status or legal effect.
- Do not assume a map layer, ETJ form, CSS portal record, OSSF review, permit record, survey, plat, deed or title-commitment item satisfies a title, lender, city, county, engineering, health or underwriting requirement.
- Do not paste wire instructions, account numbers, taxpayer credentials, Social Security numbers, identity-document numbers, confidential contracts, complete commitments, surveys, plats, permit packets or client documents.
- Do not offer or request a rebate, discount, commission, gift or any other benefit for sending the question or future closing.
TDI safety posture
No title-premium claim. No referral bargain. No ETJ, permit or legal opinion.
This public resource is available to anyone on the same terms. It is not conditioned on sending a closing to WG Title and it does not offer a rebate, discount, commission, gift or thing of value for a referral.
Prepared as a courtesy. This document is available to any real estate professional on the same terms and is not conditioned on directing a closing to WG Title.
WG Title provides title and escrow services, not legal advice. WG Law is a separate, independently operated company and any relationship with it is governed by its own engagement.
Read TDI Procedural Rule P-53 ->D1-first conversion path
Send the property and the first ETJ or permit process question.
This uses the existing closing-readiness form. The page URL, referrer, UTM fields and click IDs stay with the lead record, so the title team can see that the question came from this Collin County ETJ and permit source handoff.
Do not paste wire instructions, account numbers, taxpayer credentials, Social Security numbers, identity-document numbers, confidential contracts, complete commitments, full plats, surveys, permit packets or client documents into this form.
