Georgia’s New 45-Day Land Disturbance Permit Deadline: What SB 447 Means for Every Metro Atlanta Developer

The Short Version: Georgia Senate Bill 447 passed both chambers in the 2026 session and is on the Governor’s desk. Once signed, every Georgia local issuing authority must issue or deny a land disturbance permit within 45 days of a completed application, with shorter clocks of 20 days for the first resubmittal and 14 days for each one after. Miss the deadline and the local government must refund every dollar of permit fees. Resubmittal reviews are also limited to the original comments — reviewers cannot pile on new issues that did not appear the first time. For every site developer, homebuilder, and commercial owner working in Metro Atlanta, this is the single biggest change to permitting workflow in more than a decade.

If you build, develop, or engineer anything in Georgia, the rules of the permitting game just changed. On April 2, 2026 — the final day of the Georgia legislative session — the General Assembly sent Senate Bill 447 to Governor Brian Kemp’s desk. The bill amends the Georgia Erosion and Sedimentation Act (O.C.G.A. § 12-7) and rewrites how every local issuing authority in the state handles a land disturbance permit (LDP)^[1]. The most important word in that sentence is “every.” From a 0.5-acre infill home in Johns Creek to a 200-acre build-to-rent community in Cherokee County, the same statutory shot clock now applies.

At Mack Engineering, we shepherd LDPs through every Metro Atlanta jurisdiction — Fulton, Cherokee, Forsyth, Cobb, Gwinnett, Hall, and beyond — every single week. Here is exactly what SB 447 does, what it does not do, and how to position your next project to capture the benefits the day the bill becomes law.

What SB 447 Actually Says

SB 447 is short — six sections — but it rewrites four key pieces of Georgia code: O.C.G.A. § 8-2-26 (private professional provider inspections), § 12-7-3 (definitions inside the Erosion and Sedimentation Act), § 12-7-9 (LDP application and review timeline), and § 12-7-11 (denial procedures and applicant remedies). It also adds a brand-new § 36-60-34 requiring large jurisdictions to publish a real-time public permit-status website^[2].

The core mechanics, distilled:

Action	New Deadline	What Happens If the Deadline Is Missed
Completeness check on a new LDP application	5 days	If the local issuing authority does not notify the applicant the application is incomplete within 5 days, the application is deemed complete by law.
Initial decision on a completed LDP application	45 days	The local issuing authority must refund every applicable fee that was collected. The applicant can also petition superior court for mandamus relief, with priority on the court’s docket.
Review of the first resubmittal	20 days	Same consequence — full fee refund and mandamus available to the applicant.
Review of every subsequent resubmittal	14 days	Same consequence. Reviewers also cannot raise new issues outside the scope of their prior comments unless the applicant added unrelated material.
Acceptance of a private professional provider’s inspection report	2 business days	The inspection is automatically accepted, work continues, and the local government cannot pause progress while it catches up on its review.
Public permit-tracking website (jurisdictions issuing 250+ permits per year)	Jan. 1, 2028	Every covered local government must publish real-time, free, login-free status data for every permit, including missed-deadline flags.

A few statutory definitions matter more than they first appear. SB 447 formally defines a “completed application” as one containing all information and supporting documentation required by the local issuing authority. It defines a “material addition” as anything added to a resubmittal that is not directly tied to a reviewer’s prior comment. That single definition is the gate that prevents counties from re-opening closed issues on the third or fourth round.

Why This Bill Happened (And Why It Matters in Atlanta)

For years, Metro Atlanta developers have complained that permit timelines were unpredictable, that reviewers added new comments on every round, and that even straightforward residential plans were sitting on a desk for 90, 120, or 180 days. The Atlanta Business Chronicle reported in December 2025 that approval delays were measurably slowing housing production across the region, and Georgia lawmakers spent the 2026 session looking for fixes. SB 447 was the only one to make it through both chambers.

SB 447 was the lone substantive housing-permitting reform to pass the 2026 Georgia General Assembly, according to the Housing Affordability Institute’s 2026 state legislative tracker. HB 1166, the much-discussed 400-square-foot ADU bill, passed the House 111-50 on Crossover Day but never received a Senate vote and died when the legislature adjourned on April 6, 2026. SB 447 is the reform that actually became law.

What This Means If You Are a Developer or Builder in Metro Atlanta

Predictable Schedules — and Real Financial Recourse

Under the previous version of § 12-7-9, Georgia already required local issuing authorities to act on an LDP application “as soon as practicable” but in no event more than 45 days after filing. The problem? The statute had no teeth. SB 447 puts teeth in the law. If the 45-day clock runs out, the local issuing authority must refund every applicable fee that was collected, and the applicant can petition superior court for mandamus relief with priority on the docket^[3]. For a typical 50-acre residential subdivision in Cherokee or Forsyth County, that is thousands of dollars at stake plus the cost-of-capital savings of starting work weeks or months sooner.

Scope-Locked Resubmittals

The most quietly powerful provision in SB 447 is this single sentence in the new § 12-7-9(c): “the local issuing authority may not issue any comments on aspects of the application that are not related to its initial comments on such application or any changes made in a resubmission of the application.” In plain English: once a reviewer has issued the first round of comments, they cannot invent new issues on round two, three, or four unless your team added something unrelated. This ends the “death by a thousand resubmittals” problem that has plagued Metro Atlanta site work for a generation.

Faster Inspections, Faster Construction

Section 1 of SB 447 also reworks how private professional provider (PPP) inspections work under the Georgia Building Code. When a PPP submits an approved inspection report, the local government has two business days to flag deficiencies in writing. If it does not, the inspection stands and the project keeps moving. Critically, the statute now reads that “in no event shall any deficiency in an inspection report or a correction to such report prevent the completion of work that has been approved by the private professional provider or otherwise delay the progress of the project.” For builders, that means inspector backlogs no longer have to stop a foundation pour or a slab inspection.

Sunlight on Permit Status

By January 1, 2028, any Georgia county, city, or consolidated government that issued more than 250 building permits in the prior year must publish a real-time, free, login-free public website showing every permit’s current status, the reviewing department, the most recent update date, the statutory basis for any denials, and any missed deadlines. Every meaningful Metro Atlanta jurisdiction — Fulton, Cherokee, Forsyth, Gwinnett, Cobb, DeKalb, Hall, Bartow, Paulding — clears that threshold easily. For the first time, applicants will be able to verify whether a county is actually meeting its deadlines^[4].

Five Things SB 447 Does NOT Change (Read Carefully)

• It does not change the underlying Georgia EPD NPDES Construction General Permits (GAR100001, GAR100002, GAR100003). The 50-acre simultaneous disturbance cap, the 67 cy/acre sediment storage requirement, the 14-day stabilization rule, and every other Blue Book best management practice still apply exactly as written.
• It does not lower the substantive engineering standard for an ES&PC plan. A site that did not meet § 12-7-6 yesterday still does not meet it today — the clock just runs faster on the review.
• It does not apply to Developments of Regional Impact (DRIs) as determined by the Georgia Department of Community Affairs. DRIs still follow their own review track.
• It does not toll the clock indefinitely. Review time is only paused while a separate state agency is conducting an external portion of the review, and the local issuing authority must give the applicant a written list of which items go to which external reviewer.
• It does not eliminate stormwater management review, utility approvals, or other companion regulatory items. But — and this is important — SB 447 explicitly subjects all of those companion items to the same 45/20/14-day clock if the local issuing authority is the body approving them.

How This Plays Out in Metro Atlanta County by County

Cherokee County

Cherokee County’s current LDP process already imposes a second-failed-submittal team meeting and requires an annotated comment-response document with every resubmittal^[5]. Those internal procedures continue to be valid under SB 447 — but they now have to fit inside the statutory 14-day clock for any submission after the first resubmittal. Applicants in Canton, Hickory Flat, Woodstock, and Holly Springs should expect a meaningful workflow change at the county.

Forsyth County

Forsyth’s Unified Development Code currently gives reviewers six business days to review each resubmittal^[6]. That is already faster than SB 447’s statutory floor, so the practical impact in Cumming will be more about the scope-lock on comments and the fee-refund hammer than the day-count.

Fulton County and the City of Atlanta

For high-volume permitting bodies like Fulton County Public Works and the City of Atlanta, the public-tracking-website requirement is the heaviest lift. Both jurisdictions issue well over 250 permits per year, and both will need to either build a compliant portal or expose a third-party permitting system by January 1, 2028.

Cobb, Gwinnett, Hall, and Bartow

These counties all clear the 250-permit threshold and all currently quote informal LDP turnarounds that exceed the new 45-day statutory ceiling for the initial round. Expect process reorganization in the back half of 2026.

A 7-Step Action Plan for Your Next Project Under SB 447

1. Submit a genuinely completed application. The 5-day completeness window is now a meaningful gate — silence past day 5 deems your application complete, but a single missing item resets you to day zero.
2. Front-load your ES&PC plan, hydrology study, stormwater report, and utility approvals. SB 447 forces the local issuing authority to roll all companion items into one clock; you should mirror that on your side and submit everything together.
3. Insist on written, statute-cited denial reasons. The amended § 12-7-11(a) requires the local issuing authority to provide “a written list of the reasons for such denial or nonacceptance and sufficient information and documentation supporting each such reason.” Hold them to it.
4. Document every clock-start date in writing. A clean paper trail (submission receipt, completeness notice, denial letters) is the foundation of a fee-refund claim or a mandamus petition.
5. Use private professional provider inspections wherever your municipality allows them. The two-business-day automatic-acceptance rule is one of the most valuable scheduling tools in the new statute.
6. Treat each resubmittal as scope-locked. If a reviewer raises a new issue, ask in writing whether it is tied to their original comments or to a “material addition” you made. If it is neither, the law no longer authorizes the comment.
7. When in doubt, ask your civil engineer. Process errors at the submittal stage are the single most common reason an LDP review stalls — and SB 447 makes engineer-led submittal discipline more valuable, not less.

How Mack Engineering Helps Clients Win Under the New Rules

Mack Engineering is a full-service civil engineering and land development firm based in Alpharetta, Georgia. We serve clients from Milton and Canton to Athens and downtown Atlanta. Our practice is built on the exact services that SB 447 puts on the clock:

• Feasibility reports and concept site plans before money is spent on full design.
• Zoning exhibits, land disturbance plans (LDP), and grading plans that pass first-round review.
• In-house stormwater design and hydrology studies so reviewers cannot stall a project on a missing companion item.
• Sanitary sewer and septic system design, erosion and sediment control plans, and land planning across the Metro Atlanta market.
• ADU designs and engineering, Revit modeling, and water-loss auditing for clients with specialized needs.

When a Metro Atlanta land development project lands at our desk, we engineer it to clear the new 45-day SB 447 clock the first time — not the third. That is the entire point of how this firm was built^[7].

Frequently Asked Questions

When does Georgia SB 447 take effect?

SB 447 passed both chambers of the Georgia General Assembly during the 2026 session and now awaits the Governor’s signature. The permitting-timeline and fee-refund provisions take effect upon signature; the public permit-tracking website requirement takes effect on January 1, 2028^[8].

What is a Georgia land disturbance permit?

A land disturbance permit (LDP) is the local approval required under the Georgia Erosion and Sedimentation Act (O.C.G.A. § 12-7) before any land-disturbing activity — clearing, grading, excavation, filling, or deposition — can begin on a site. In most Metro Atlanta jurisdictions, an LDP is required whenever the cumulative disturbance equals or exceeds one acre, or whenever soil is disturbed within 200 feet of state waters.

Does SB 447 apply to single-family homes?

SB 447 amends the state-wide erosion and sedimentation permitting framework, which applies to any land-disturbing activity not covered by a statutory exemption. Most one- and two-family residential construction below the one-acre disturbance threshold is exempt from the LDP requirement altogether under existing law, and SB 447 does not change those exemptions. For permitted activity, however, the new clocks apply.

What happens if my Cherokee County or Fulton County LDP is not decided in 45 days?

The local issuing authority must refund every applicable fee you paid in connection with the permit application. You can also petition the superior court for mandamus relief, and your petition will be given priority on the court’s docket.

Does SB 447 replace the Georgia NPDES Construction Permits?

No. The Georgia EPD NPDES Construction Stormwater General Permits (GAR100001, GAR100002, GAR100003) remain in effect through July 31, 2028, exactly as written. SB 447 changes how local governments process permits; it does not change the substantive environmental standards in the NPDES permits or in the Georgia Stormwater Management Manual.

Does SB 447 apply to commercial and industrial projects, or only residential?

Both. The statutory amendments to § 12-7-9 apply to any LDP application from any project type. The only categorical exclusion is for Developments of Regional Impact (DRIs) as determined by the Department of Community Affairs.

Bottom Line

For the first time in a generation, the Georgia permitting clock has consequences. Local governments that drag their feet must write checks. Reviewers can no longer reopen closed issues on the fourth round. Private inspections clear themselves in two business days. And the public will be able to watch every permit move in real time.

The catch — because there is always a catch — is that the new law rewards engineering teams that submit clean, complete, defensible packages the first time, and punishes the ones that do not. A near-complete submittal that triggers a single completeness reset can give back the entire advantage SB 447 was designed to deliver.

If you have a project teed up in Fulton, Cherokee, Forsyth, Cobb, Gwinnett, Hall, or anywhere else in the Metro Atlanta market, the next 90 days are the right window to align your civil engineering, stormwater, and permitting strategy with the new statute. Contact Mack Engineering to walk through your project. We will tell you what SB 447 means for your specific schedule, your specific site, and your specific budget — and then we will engineer it to win the 45-day clock.
