Flat concrete on your own lot usually needs no building permit. Anything that touches the curb, gutter, sidewalk or driveway approach needs a City of Oakland Curb, Gutter, Sidewalk (CGS) permit. The points below come from the City's own pages and from state law. Rules change, so we confirm them for your address before work begins.
Do I need a permit for a driveway or patio?
For a patio on the ground on your own lot, usually not. The California Building Code, section 105.2, exempts sidewalks and driveways that are not more than 30 inches above the adjacent grade, are not over a basement or story below, and are not part of an accessible route. That is an exemption from the building permit only. Zoning rules still apply. For a driveway you do need a permit for the part in the public right of way. Oakland requires a CGS permit to install, remove, widen or repair a driveway or to cut into a curb, gutter or sidewalk. OakDOT issues it after zoning approval.
Do I need a permit to widen my driveway?
Yes. Oakland lists widening a driveway among the jobs that need a CGS permit. For lots with one or two dwelling units, the City limits the driveway to 19 feet wide across the front 20 feet of the lot, limits the curb cut to 19 feet, and allows one driveway and one curb cut per street frontage. A wider curb cut also removes street parking, which is one reason the City reviews it.
Who owns the driveway apron: me or the city?
The apron, meaning the sloped part between the street and your property line, lies in the public right of way. You do not own the land, but the upkeep is yours. Oakland treats it with the sidewalk, and any work on it needs the CGS permit. Only state-licensed contractors holding a suitable class, such as A, B or C-8, with an Oakland business tax certificate can be issued that permit.
Who is responsible for the sidewalk in front of my house?
You are. The City of Oakland cites California Streets and Highways Code section 5610 and Oakland Municipal Code section 12.04.380, which place sidewalk maintenance on the owner of the fronting property. There is one stated exception. Where the damage comes from a tree the City has recorded as an official City tree, the City is responsible for that repair.
Oakland also requires a Sidewalk Compliance Certificate before a property's title is transferred and before a permit is issued for renovations valued above $100,000.
The city sent a notice to fix the sidewalk. What do I have to do?
If the city sent you a Notice to Repair, Oakland says you must repair the sidewalk within 30 days. Repairs of 25 square feet or more need a CGS repair permit. Smaller repairs do not, but the City says a licensed contractor should do them. If you believe an official City tree caused the damage, call 311 and ask the City to check its records before you spend money.
Must I use the city's contractor, or can I hire my own?
You can hire your own. Oakland lets you choose any properly licensed contractor. Licensed contractors in the right classes can also self-certify the repair for the compliance certificate. Oakland lists a Sidewalk Assistance Program as well. We have not confirmed its current terms, so ask the City if you want to compare.
How close to the property line can I pour?
Flatwork can generally run up to the property line, because a slab on the ground is not a structure with a setback. Two cautions apply. Water from your slab should not be sent onto the neighbor's lot. And Oakland's zoning rules govern front yard paving and parking, which we have not been able to confirm in detail. Walls, steps over 30 inches and anything roofed do have setback rules.
Do I need a survey?
Not for most replacement work that stays in the old footprint. A survey is worth the money when new concrete or a wall will run along a boundary nobody is sure of, when a fence is the only marker, or when a neighbor disputes the line. On Oakland's narrow lots and shared driveways a few inches can matter.
Do I need HOA approval?
If your home is in a homeowners association, yes, check first. HOA rules are separate from City permits and can cover color, finish, driveway width and work hours. Townhouse and condominium communities around Oakland and Emeryville often own the driveways themselves. Get approval in writing before signing a contract.
How much of my lot can I cover with concrete?
Oakland's Planning Code controls lot coverage, landscaping and front yard paving by zone, and new impervious surface adds stormwater runoff. We could not verify a percentage for front yards, so we give no number. What we did confirm is the 19 foot driveway width limit at the front of one and two unit lots. For a mostly paved yard, ask the Planning Bureau or have us check your zone.
When does a retaining wall need a permit or an engineer?
In Oakland a retaining wall needs a building permit unless it is not over 4 feet high, measured from the bottom of the footing to the top of the wall, and is not supporting a surcharge. A surcharge is load above the wall such as a driveway, slope or building. The City's permit page says structural calculations are required with the application, which in practice means an engineer. Walls visible from the street or neighboring lots need design review, and walls generally may not exceed 8 feet.
How do I find underground utility lines before digging?
Contact USA North 811 by dialing 811 or at usanorth811.org. It is the free call-before-you-dig center for Northern and Central California. The request has to go in at least 2 working days before digging, not counting the day you make it. Outline the dig area in white beforehand. The utilities then mark their utility lines, and the ticket lasts 28 days. Within 24 inches of a mark, digging is done with hand tools. Sprinkler pipe, yard lighting and other private lines are not marked.
I need a wheelchair ramp and a wider walkway. What rules apply?
For a private home there is no single required ramp design, but the common guide is a slope no steeper than 1 inch of rise per 12 inches of run, with level landings at the top and bottom. A ramp is treated differently from flatwork: the state exemption does not cover accessible routes, and a ramp more than 30 inches above grade needs a permit and guards. Businesses and rental housing must follow the accessibility chapters of the California Building Code. We have no published price for ramps and quote them after measuring.
My house is in a historic district or has old decorative concrete. Can I change it?
Check with the Oakland Planning Bureau before removing anything. Oakland has designated landmarks and preservation districts where exterior changes are reviewed. We have not confirmed which concrete work falls under that review. Old scored sidewalks, contractor stamps and tinted walks are part of the character of many blocks, and where possible we cut repairs along existing score lines and match the pattern.
Creeks and steep slopes bring extra rules. Oakland regulates work close to creeks and requires engineering for grading and walls on steep or slide-prone ground. We have not verified the exact triggers, so we ask the City about any site beside a creek or on a steep hillside before quoting.
The only real price for your job comes from a free visit, a tape measure and a written quote. Call (510) 694-1913 or text us a photo of the area.
