Deck Permit in Riverside County, California
It depends
Sometimes, depending on the project
Before building a deck over 200 square feet, more than 30 inches above grade, attached to the house, or serving the required exit door, in unincorporated Riverside County
By Mario Bailey, verified against official sources
Quick answer
Riverside County's deck exemption is a four-part test: the deck must be 200 square feet or less, no more than 30 inches above grade at any point, not attached to a dwelling or townhouse, and not serving the required exit door. Fail any one of those and a building permit is required, filed either against the county standard deck plan or as an engineered deck. This applies to unincorporated Riverside County; the county's incorporated cities run their own building departments.
Typical threshold: A deck is exempt only if it is 200 square feet or less in area, no more than 30 inches above grade at any point, not attached to a dwelling or townhouse, and does not serve the required exit door.

How to apply in Riverside County
A residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- A permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- A scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- A deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- A section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
Deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Riverside County permit portal or by phone at 951-955-1800.

- Where do you apply for a deck permit in Riverside County?
- You can apply through the Riverside County permit portal or contact the Riverside County Building and Safety Department (Transportation and Land Management Agency) directly. The links are listed on this page.
- Can a homeowner pull a deck permit themselves in Riverside County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner-builder from contractor licensing when the owner personally performs the work, or uses only wage employees, on their own property and does not intend the improvements for sale. A homeowner may also directly hire licensed trade contractors for up to four single-family residences a year, or improve their own principal residence without a general contractor's license, as long as they have actually lived there for the 12 months before the work is finished. Selling a self-built structure within one year of completion creates a rebuttable presumption that it was built for sale, which defeats the exemption, and selling five or more structures within a year makes that presumption conclusive. Separately, every city or county that requires a building permit must also require the applicant to file a signed statement giving their contractor license number or the basis of their claimed exemption; a false or missing statement carries a $500 civil penalty. Confirm how Riverside County applies this before you apply.
