Northlake, Texas Building Permit Guide

Inside Northlake town limits, building and trade permits are issued by the Town’s Development Services Department and applied for online in Community Core. The Town partners with SAFEbuilt for plan review and inspections. A new single-family home costs $0.80 per square foot of conditioned floor area (minimum $1,000) plus a $100 plan review fee, and the master building permit covers the electrical, plumbing and mechanical work.

What requires a permit in Northlake?

The Town’s rule is that a building permit is needed before any building or structure is built, and most home improvement projects need one too. The permit types the Town lists include:

No permit is needed for a detached tool or storage shed or playhouse up to 120 sq ft, or for minor repair and maintenance. A building permit is issued only on a platted lot, or on land with an approved development plat where no subdivision plat is required, and only if the project meets the Unified Development Code.

Who handles permitting in Northlake?

Development Services runs permitting, inspections, code enforcement and planning for the Town. The Permit Technician handles applications, process and fee questions; SAFEbuilt reviews plans for building code compliance and carries out building and health inspections for the Town. The Town’s 2021 construction guides still name Countywide Inspection Services for that role, and the inspection email address on the current page is the same one those guides list. Fire plan review and fire inspections are run by Denton County Emergency Services District No. 1, which serves Northlake along with Argyle, Bartonville, Copper Canyon, Corral City and Lantana. Land outside the town limits is in unincorporated Denton County.

Community Core, contractor registration and forms

Permits are filed online in Community Core. Register an account first: contractors register as contractors, and property owners doing their own work choose Community Member. The Town posts instructions for using the software on its permit pages.

All electrical, mechanical, plumbing and irrigation contractors must be registered with the Town before they get a permit or work in town, and the registration lasts one year. Trade subcontractors are listed on the master building permit; a stand-alone trade job uses the Miscellaneous Permit application.

Applications posted by Development Services include the Residential and Commercial Building Permit Applications, Certificate of Occupancy application, Fence, Irrigation, Pool Construction (with a notary letter), Driveway-Culvert, Water Well, On Site Sewerage Facility, Floodplain Development, Fire Protection, Sign, Tent and Oil and Gas Well permit applications. Right-of-way permits are requested through the Town’s separate OpenGov portal.

Northlake permit fees

Building fees are set in Appendix A, Article A2.000 of the Code of Ordinances, adopted by Ordinance 24-0613D on June 13, 2024. Plan review fees are non-refundable and due with the application; the rest is paid when the permit is issued.

For example, a new home with 3,000 sq ft of conditioned space pays $2,400 for the permit plus the $100 plan review fee. Electrical, plumbing and mechanical work on a master building permit is included in that fee. New water service can add a deposit, tap fee, meter placement fee and a cost recovery or impact fee.

Electrical, plumbing, mechanical and fire coordination

A new house or commercial building normally gets one master building permit that covers the electrical, mechanical and plumbing work, with each registered trade contractor listed on it. Trade work that is not part of a master permit is charged $50 if it needs only one inspection, or by the valuation table if it needs more.

Fire protection: SAFEbuilt is the only third-party plan reviewer for fire service work in Denton County ESD 1. Its stamped approved drawings, equipment data package and approval letter act as the authorization to start work, because the ESD’s Fire Marshal’s Office does not issue fire permits itself. Small jobs, such as sprinkler systems of 5 heads or fewer and fire alarm work adding or replacing 3 devices or fewer, send as-built drawings and cut sheets straight to the ESD. Before a final fire inspection is scheduled, submit as-built drawings, the ESD inspection request form and a fee receipt; fees are paid in advance at 511 S. Gibbons Road, Argyle.

What to submit for a new home

• Completed Residential Building Permit Application
• One set of building plans
• A scaled site plan showing all existing and proposed improvements and the setbacks of new structures from every property line
• An engineered foundation plan signed and sealed by a professional engineer
• Energy code compliance worksheets
• The $100 plan review fee

Interior remodels can skip the site and foundation plans when nothing changes outside or under the house. Accessory buildings need the application, plans and a site plan, plus energy worksheets if the building will be air-conditioned. A septic application needs a valid site evaluation and a site plan with measured distances, wells and water features, slopes over 15%, easements and any floodplain, and an area of about 5,000 sq ft reserved for the drain field.

How to get a Northlake permit: 6 steps

Inspections and closeout

Request inspections by email at inspections@cwistx.com or by phone at 940-521-0470; the Town’s residential guide says emailed requests are inspected the next business day. Your permit’s required inspections are listed on the checklist in Community Core: open the permit record, choose Documents, then the System-generated tab.

A typical house is inspected in this order: temporary power pole, plumbing rough, foundation, “seconds” (electrical rough, plumbing stack-out, mechanical rough and framing together), insulation, drive approach, an optional temporary utilities inspection, and finals. A failed inspection costs $60 to re-inspect on a home and $72 on a commercial job.

Commercial buildings get a Certificate of Occupancy once all final inspections pass, and they may not be occupied before it is issued. The final fire and life safety inspection is scheduled only after the ESD has every required document on file.

Texas building code

Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
