The rule in 5 cities, with their permit counts
Rules from each department's own page, read 23 October 2026. Counts are permits in the city's patio category over three years to September 2026, and the categories are broader than patio covers: Scottsdale includes ramadas, Albuquerque sunrooms, Denton decks and porches, Citrus Heights and Sacramento County other accessory structures.
| City | The rule | Permits | Usual filed value | Usual days to final |
|---|---|---|---|---|
| Sacramento County (unincorporated) | "Patio Cover, Porch, Enclosure" is on its permit list | 631 | $19,294 | 86 |
| Scottsdale, AZ | "A building permit is required for any attached addition to the residence including the construction of an attached patio cover" | 424 | $20,797 | — |
| Denton, TX | "Permits are required"; site, elevation, framing and foundation plans | 190 | $19,412 | 44 |
| Citrus Heights, CA | Exempt if under 120 square feet: floor area for walled structures, roof area for open ones | 155 | $8,690 | 90 |
| Albuquerque, NM | Covered patios fall under "Porches and Carports": zoning check first, posts on footings at least 18 inches square and 16 inches below grade | 187 | $15,241 | — |
Scottsdale and Albuquerque show no days because their files carry no final date we can time.
Six more departments, without patio cover counts in our file:
| Building department | The rule |
|---|---|
| San Diego, CA | Exempt up to 300 square feet, 12 feet above grade and outside the setback, "unless in the Coastal Overlay Zone or a Planned Development"; historic districts need a permit |
| San Diego County (unincorporated) | Exempt: "Patio covers, carports, and horse shade covers" up to 300 square feet of projected roof; electrical may still need a permit |
| Waco, TX | A covered porch counts as a Residential Addition and needs a permit; wall-supported awnings up to 54 inches do not |
| Cary, NC | A screened or open porch needs a permit; a "trellis/pergola with open roof" does not |
| Seattle, WA | Exempt: "Arbors or other open-framed landscape structures that don't exceed 120 square feet" |
| Pikes Peak Regional (Colorado Springs) | Exempt: shade cloth structures up to 200 square feet of fabric, and window awnings projecting no more than 54 inches |
Roof, walls and wiring change the answer
Three things move a patio cover into permit territory. A solid roof: the open-roof pergola is exempt in Cary, a roofed porch is not. Walls: Citrus Heights measures walled structures by floor area and lists "Addition of an enclosed patio" as permit work, and Sacramento County lists enclosures with patio covers (more in home addition permits). Wiring: San Diego County says separate electrical permits "may be required" even for an exempt cover, and Scottsdale permits electrical added to an existing one. A fan or light on the cover is electrical work; see electrical work permits.
Who pulls it
The builder, or you on your own home. Scottsdale's patio cover handout includes building plans "for your use", with the rule "You cannot exceed the building dimensions that are shown." Denton requires a pier or foundation inspection, an electric rough if the cover is wired, and a building final. Albuquerque requires rafters to bear on the wall top plate or a ledger fastened to the studs, never directly on the fascia or truss tails.
How long it takes
The usual permit closed in 44 days in Denton, 86 in Sacramento County and 90 in Citrus Heights. 93.7% of Citrus Heights's permits a year or more old reached a final, against 51.3% of Scottsdale's. Hold back part of the last payment until the final passes.
Check it in five minutes
- Measure the roof area and the height at the highest point.
- Decide the roof type: open slats, solid or louvered. Open is exempt in more places.
- Check the setback to the nearest property line; San Diego's exemption is lost inside the setback.

What this does not tell you
We read 11 departments' rules; HOA rules are separate. Our five patio categories mix patio covers with decks, porches, ramadas, sunrooms or accessory structures, so the counts overstate patio covers alone.
How we know this
Rules are quoted from the pages under Sources, read 23 October 2026. Permit counts, filed values, usual days to final and finished shares come from each city's permit file over the three years ending September 2026. "Usual days" is the median from issue to final inspection; "reached a final" counts permits a year or more old.
Numbers come from Sacramento County building permits on single-family, duplex and townhouse homes in the unincorporated county (the County's Accela permit layer); City of Scottsdale building permits (the City's open-data permit file up to January 2026, and the City's SPUR permit system since), with the contractor named on each permit; City of Denton Building Safety permits on homes (the city's yearly permit reports); City of Citrus Heights building permits on homes (the city's issued-permits layer); City of Albuquerque building permits, data through October 17, 2026. Nobody paid to be on this page and nobody can.
Questions
- How big can a patio cover be without a permit?
It depends on the city. San Diego and San Diego County exempt patio covers up to 300 square feet; San Diego also caps the height at 12 feet and keeps them out of setbacks, the Coastal Overlay Zone and Planned Developments. Citrus Heights exempts open structures up to 120 square feet of roof. Denton, Scottsdale and Sacramento County list patio covers as permit work with no size exemption.
- Does a pergola need a permit?
Often not, if the roof is open. Cary exempts a 'trellis/pergola with open roof', and Seattle exempts arbors and other open-framed landscape structures up to 120 square feet. A solid or louvered roof makes it a patio cover in most of these cities.
- Do I need a permit to replace an existing patio cover?
In Scottsdale, yes: a permit is required 'for the repair and replacement or an existing patio cover', and 'Any electrical that is added to an existing patio cover also requires a permit.'
- How long does a patio cover permit take?
The usual permit in these categories reached its final inspection in 44 days in Denton, 86 in Sacramento County and 90 in Citrus Heights. Denton requires a pier or foundation inspection, an electrical rough if wired, and a building final.
- What does a permitted patio cover cost?
The usual filed value was $20,797 in Scottsdale (patio covers and ramadas), $19,294 in Sacramento County and $8,690 in Citrus Heights. Filed values are what the contractor wrote on the application.
