What Happens If Your Grading Permit Expires Before Your San Diego Addition Is Finished?
A San Diego grading or right-of-way permit is only good for so long. Here is exactly how long, how to extend it before the clock runs out, and what it costs you if it lapses anyway.

Key takeaways
- 24 months is the standard term. A San Diego grading or right-of-way permit expires 24 months after issuance, or sooner if it is tied to a subdivision improvement agreement or an associated building permit, whichever comes first.
- You can request an extension, but only in a 60-day window. Applications for an extension of time must be filed no earlier than 60 calendar days before the permit’s expiration date, on form DS-340.
- What you owe if it lapses depends on how much is built. Fully completed and inspected work mostly needs paperwork, not a new plan check. Anything under 75% complete has to be re-checked against whatever code is current when you reapply.
- Extensions carry their own fees, separate from your original permit cost: an application extension and an issued-permit extension are priced differently in the city’s current fee schedule.
- A temporary state extension has already lapsed. Assembly Bill 2729 gave some 2024-and-earlier permits extra time, but only if they were set to expire before the end of 2025 — it does not help a permit expiring in 2026 or later.
- This guide covers grading and right-of-way permits specifically. Your project’s building permit runs on its own separate expiration terms.

Why a Grading Permit Matters on an Addition or New Build
A building permit and a grading permit are not the same document, and a San Diego project can need both. The building permit covers the structure itself. A grading or public right-of-way permit covers the earthwork, drainage and street-facing work that a larger addition, a new home, or a whole-home remodel with site changes can trigger. Not every project needs one on its own; the City of San Diego evaluates that based on the amount of earthwork, retaining walls and drainage change involved, and a bond is required for that grading work above a set construction-cost threshold.
The reason this matters is timing. Design-build additions and new-construction projects in San Diego routinely run past 12, 18 or 24 months once you count design, plan check, and construction. A grading permit issued at the start of that timeline can expire before the project is finished, and the rules for what happens next are specific.
How Long a Grading Permit Lasts Before It Expires
Under San Diego Municipal Code §129.0650 and §129.0750, a grading or right-of-way permit expires on whichever of these dates comes first. That last condition matters on a design-build addition: if your grading permit is tied to a building permit that expires earlier, the grading permit expires on that earlier date too, not on its own 24-month mark.
| Trigger | When it controls |
|---|---|
| 24 months after issuance | The default term for most grading and right-of-way permits |
| Linked subdivision improvement agreement | Permit expires with the agreement, if that date is earlier |
| Linked building permit | Permit expires with the building permit, if that date is earlier |
| Date set at issuance | Some permits are issued with a specific expiration date instead |
Requesting an Extension Before the Clock Runs Out
The city allows extensions, but the window to ask for one is narrow and easy to miss on a busy job site. Per Information Bulletin 306, a permittee may apply for an extension of time no earlier than 60 calendar days before the permit’s expiration date, using form DS-340. Two consecutive 180-day extensions are available where circumstances beyond the applicant’s control prevented finishing on time.
File too early and the request is not eligible; file after the permit has already expired and you are dealing with an expired permit, not an extension, which is a materially different process described in the next section. Mark the expiration date on your project schedule the day the grading permit is issued, not when it starts to feel urgent.
- Extension requests use Application for Extension of Time for Grading/Right-of-Way Permits, form DS-340.
- Two consecutive 180-day extensions are the standard allowance for delays outside the applicant’s control.
- The 60-day pre-expiration window applies to the request itself, not to when work must resume.
What Happens If It Expires Anyway
If the window closes and the permit lapses, Information Bulletin 306 is specific that a new permit application is required unless the only remaining items are administrative. What that new application actually costs you in time is tied directly to how much of the graded work was done and inspected before the lapse.
| Work completed & inspected | New plan check required | Bonding |
|---|---|---|
| 100% complete | Not required | Bond Rider only, if a bond originally applied |
| 75% or more complete | Not required | Bond Rider only, if a bond originally applied |
| Less than 75% complete | Required, to confirm compliance with current regulations | Bond Rider only, if a bond originally applied |
| Construction never started | Same process as a brand-new permit | Original bond released once a new bond is accepted |
The 75% line is the one worth planning around. A project that stalls at 60% complete does not just pay a fee to pick back up — it goes back through plan check against whatever grading and drainage standards are current on the day it reapplies, which may not be the same standards it was originally approved under.
This entire guide describes grading and public right-of-way permits. Your project’s building permit is a separate document with its own expiration terms under the locally adopted building code, and the two do not automatically move in lockstep unless the grading permit was explicitly tied to the building permit’s date. Confirm the status of both permits with San Diego’s Development Services Department, not just one.
What an Extension or Reinstatement Actually Costs
Extension fees are billed separately from whatever you already paid to obtain the permit, and the two extension types are priced differently depending on whether you are extending an application that has not yet become a permit, or a permit that has already been issued.
| Fee | Amount | Applies to |
|---|---|---|
| Extension of Time – Application | $176.57 | An expired application, before a permit has been issued |
| Permit Extension | $353.13 | An issued grading or right-of-way permit nearing its expiration date |
Both are administrative fees, not construction costs — they do not include any new plan check or inspection fees that a lapsed, under-75%-complete permit would also trigger.
The AB 2729 Exception, and Your Building Permit’s Separate Clock
Information Bulletin 306 notes that Assembly Bill 2729 gave an 18-month extension to certain housing project permits, but only to permits issued before January 1, 2024 that were set to expire before December 31, 2025. If your grading permit was issued more recently, or expires in 2026 or later, this state provision does not apply to your project — plan on the standard 24-month term and the two 180-day extensions described above.
Keep the building permit on a separate mental calendar. Information Bulletin 306 addresses the building permit only as one of the conditions that can end a grading permit early; it does not set out the building permit’s own expiration rule. On a whole-home remodel, addition, or new build using both permit types, confirm each permit’s status independently with Development Services rather than assuming one expiration date covers both.
Does every home addition or new home build in San Diego need its own grading permit?
Not automatically. A grading permit is required when a project’s earthwork, drainage changes or right-of-way work cross the city’s thresholds, and a bond is required above a set construction-cost estimate on that grading work. Confirm with San Diego Development Services whether your specific scope needs one.
How long is a San Diego grading or right-of-way permit valid before it expires?
24 months from issuance is the standard term, but it can end sooner if the permit is tied to a subdivision improvement agreement or an associated building permit that expires first, or if a different date was set when the permit was issued.
Can I extend my grading permit if my project is running long?
Yes. File an Application for Extension of Time for Grading/Right-of-Way Permits (form DS-340) no earlier than 60 calendar days before the permit expires. Two consecutive 180-day extensions are the standard allowance for delays outside your control.
What happens if I miss the deadline and the permit expires?
It depends on how much work was completed and inspected. Fully or 75%-plus complete work mainly needs a Bond Rider and administrative close-out items. Anything under 75% complete requires a new plan check against current regulations before work can continue.
How much does a grading permit extension cost in San Diego?
Per the city’s current fee schedule, an Extension of Time for an application is $176.57, and a Permit Extension for an already-issued permit is $353.13. These are administrative fees and do not include any new plan check or inspection costs a lapsed permit might also require.
Is Assembly Bill 2729 still giving extra time to permits in 2026?
No. That state provision only extended permits issued before January 1, 2024 that were set to expire before December 31, 2025. A grading permit expiring in 2026 or later follows the standard 24-month term and the two 180-day extensions instead.
Does my building permit expire on the same schedule as my grading permit?
Not necessarily. A grading permit can be set to expire on the same date as a linked building permit, but the building permit itself follows its own separate expiration terms under the locally adopted building code. Check the status of both permits, not just one.
Keep Every Permit on Your Project Moving
A design-build addition or new home involves more than one permit clock running at once. Eco Home Builders manages design, engineering and construction under a single contract, and tracks permit deadlines as part of that scope so a lapsed grading permit never becomes a surprise mid-project.
