Do I need a roofing permit in unincorporated San Diego County? The re-roof sheet, cool-roof rule and $926 in fees

The County rule

The County's adoptive ordinance (PDS 110, rev. 1 January 2026, read 23 October 2026) requires a permit to "construct, enlarge, alter, repair ... a building or structure". Its building exemptions cover small sheds, low fences and walls, decks and driveways under 30 inches, painting and similar finish work, but not roofing, so even a shingle-for-shingle swap is permit work.

The County's Residential Re-Roof Referral Sheet (PDS 641A, rev. 15 April 2024) is the form your roofer fills in. What it asks:

The steep-slope cool-roof exceptions on the sheet include "50% or less of roofing area replaced", "Reinstallation of concrete or clay tile permitted (i.e., lift and re-lay)", "Project is in climate zone 7", minimum R-38 ceiling insulation, a radiant barrier in the attic, roofs of 25 pounds per square foot or more, and roof area covered by integrated PV. The inspector verifies the insulation-based ones on site. A recover over existing roofing "is required to comply unless exempted".

Who pulls it

Usually a roofer with a CSLB C-39 Roofing license or a general contractor; 85.4% of the 294 roofing firms on County permits matched an active CSLB license in our file, and 13 carried a license that was not active. A homeowner can file as owner-builder by signing the Owner-Builder Acknowledgement (PDS 421), which makes the owner "the responsible party of record on the permit" and an employer if they pay an unlicensed crew $500 or more.

How to apply

1. Confirm the parcel is unincorporated. Fallbrook, Ramona, Lakeside, Alpine and the rest are County; the 18 cities permit their own.
2. Fill in PDS 641A with the roofing product's listing and cool-roof data or the exception that applies.
3. File over the counter. Re-roofs are not on the County's list of online residential permit types (Online Services Central). In the County's open data, re-roof permits opened since October 2023 sit mostly under scope "3310 - RES - Misc." (1,823 permits whose description says re-roof, all property types, none filed online; counted 23 October 2026). The sheet's top block is for the plan reviewer, who either sends you to a technician for issuance or asks for engineering.
4. Inspections and final. A sheathing job adds the roof nail inspection. Permits expire if work does not start and get a valid inspection within two years, or if work stops for 180 days (PDS 807).

What it costs

From the County's fee schedule (PDS 613, effective 10 July 2026):

The usual County re-roof permit carried $14,825 of declared value, so the over-the-counter fee is about 6% of a typical job. A roof that needs engineering (heavier tile, framing changes) falls to the plan-check line at more than twice the cost; that is a reason to ask your roofer early whether the new material weighs more than the old.

What 1,584 County re-roof permits show

Re-roofs are quick to close here, 41 days, against 63 for electrical. The spread between firms is the useful part: the 10th-percentile busy roofer closed 63.2% of its permits and the 90th 95.9%. Roofing is spread out by County standards (50.7% of firms appear on one permit) and barely seasonal: March runs at 112 and January at 83. National prices are in roof replacement cost.

What this does not tell you

Declared value is the roofer's figure on the application, not the contract price. Fire-hazard-zone roofing rules come from the fire district and the County Fire Code, which we did not review here; ask the plan reviewer at intake. Unincorporated county only.
