Do I need a permit for a new driveway in LA?

Replacing an existing driveway in the existing footprint generally does not require a building permit — it's considered maintenance. Any change triggers permits: a new curb cut requires a LADBS Bureau of Engineering A-permit ($500 + inspection fee), widening an existing curb cut is the same A-permit, adding drainage that discharges to a public storm drain requires an encroachment permit, changing driveway location triggers zoning review, and a driveway on a hillside-ordinance parcel may require grading permits per LADBS BOS. The $500 BOE curb-cut permit is the line item homeowners most often miss.

What does a real LA driveway build cost?

Budget plain concrete replacement at 500–900 sqft runs $12K–$24K — demo ($2K–$4K), base prep, 4-inch concrete with wire mesh at $10–$14/sqft, broom finish, control-joint cut. Standard stamped concrete or simple Belgard paver at 600–1,200 sqft runs $24K–$48K with added drainage and BOE curb-cut work if required. Premium architectural paver with full linear drain and integrated lighting runs $48K–$75K. Ultra hillside post-tensioned slabs with EV-charger conduit run $75K–$95K+. The biggest cost jumps: 4-inch to 6-inch concrete adds $4–$8/sqft; plain to stamped adds $8–$17/sqft; stamped to paver adds $17–$30/sqft.

How long does driveway construction take?

Budget concrete replacement runs 2–4 weeks — one day of demo, three days of base prep and rebar or mesh, one day of pour, seven days of cure before you can drive on it (28 days before full strength), then sealing. Standard stamped or paver runs 4–6 weeks. Premium architectural paver with linear drain and curb-cut permit runs 6–10 weeks because the BOE permit sits 2–3 weeks and the paver order has a 3-week lead. Ultra hillside post-tensioned runs 10–16 weeks because the PE-stamped structural plan and the PT subcontractor have scheduling constraints.

Concrete vs pavers — what's the real tradeoff?

Concrete is monolithic — one pour, joints cut to control cracks, lasts 25+ years, cheapest at $10–$35/sqft stamped. Damage requires replacing a full slab section. Pavers are individual units on a compacted base or concrete sub-slab — lasts 30+ years, individual pavers are replaceable if a truck stains one, costs $35–$65/sqft. The style reads differently: concrete reads clean and modernist, pavers read premium and Mediterranean. Pavers are the higher-maintenance choice (re-sanding joints every 3–5 years, occasional re-setting) but they also absorb movement better on LA hillside and seismic zones because the individual unit joints flex.

Can I DIY a driveway?

Small-scope yes, full driveway no. DIY-safe: patching cracks with Quikrete Concrete Crack Seal, re-sanding paver joints with polymeric sand, pressure-washing and sealing existing concrete. Not DIY: any pour over 100 sqft (concrete finish window is 30–60 min on a warm LA day — amateur pours crack and waste material), any curb cut (requires BOE permit + licensed C-8 concrete subcontractor), any drainage tied to a public storm drain, any structural slab, and any hillside grading. Baily will split scope — we handle the structural pour, you handle the paver fill-in or the sealer re-coat.

What's the real LADBS BOE curb-cut process?

The LADBS Bureau of Engineering A-permit application runs through the BOE permit counter (201 N. Figueroa or online via LADBSOnline). Submit a site plan showing existing curb, proposed cut width and location, proximity to fire hydrants and storm drains, and sidewalk tie-in detail. Permit fee is $500 base plus inspection fees that add $200–$800 depending on sidewalk dimensions. Curb cut must be at least 3 ft from a fire hydrant, at least 5 ft from a storm drain inlet, and at least 40 ft from a corner on arterial streets. ADA detectable warning strips are required if the cut is within an accessible route. Install inspection happens before and after the pour.

Does a new driveway add appraisal value?

A well-finished permitted driveway appraises at 55–70% of replacement cost in almost every LA zip — a $40K standard stamped or paver driveway adds $22K–$28K and is frequently mentioned in the MLS listing. Pavers and stamped concrete appraise higher than plain broom-finish concrete in premium zips (Beverly Hills, Palisades, Hollywood Hills, Manhattan Beach) because the curb impression signals the rest of the property condition. Unpermitted curb cuts get flagged at appraisal and either deducted or forced to be closed and re-permitted — always pull the BOE permit.

How does a driveway overlap with landscape, fence, or exterior scope?

Significantly. If we're already on-site for /landscape-design-los-angeles, /exterior-design-los-angeles, or /fence-and-gate-los-angeles, adding a driveway costs 10–20% less because the excavation, base prep, and drainage trenching overlap. The motorized gate and the driveway are paired scopes — the loop-detector groove gets cut into the concrete before the final pour, the gate photo-eye conduit runs under the slab, and the EV-charger circuit gets its stub-out during base prep. Scope standalone driveway here; bundle it into the bigger project if one is active.

What makes a driveway right in LA

Five spec decisions that separate a box-store asphalt patch from a driveway that survives heat cycling, tree roots, and EV weight over 25 years.

Surface — plain concrete vs stamped vs pavers vs permeable
Plain broom $10–$18/sqft · Stamped $18–$35/sqft · Pavers $35–$65/sqft · Permeable paver $42–$75/sqft
Plain broom-finish concrete at 4-inch thickness with rebar on a compacted base is the LA budget standard — 25+ year life if control joints are cut on time. Stamped patterned concrete (Ashlar Slate, Running Bond, from Brickform or Butterfield) hides hairline cracks and adds curb style. Belgard, Techo-Bloc, and Pavestone interlocking concrete pavers read premium and are individually replaceable. Permeable pavers (Belgard Eco-Dublin, Techo-Bloc Aquastorm) meet MS4 stormwater rules and capture LA County credits.
Base — 4" concrete vs 6" + rebar vs post-tensioned
4" + wire mesh $10–$14/sqft · 6" + rebar $14–$22/sqft · Post-tensioned $22–$38/sqft
4-inch concrete with wire mesh is fine for passenger cars — a Civic or a Tesla weighs 3,500–4,500 lb. 6-inch concrete with #4 rebar on 12-inch centers is the right call for trucks, Sprinters, or Tesla X (5,400+ lb). Post-tensioned slab (PT cables pulled at 7 days) is reserved for hillside driveways with active slope movement or heavy commercial vehicles — PE-stamped design and specialty subcontractor only.
Drainage — crown + area drain vs linear slot vs French drain
Crown + 3" area drain $800–$1,800 · Linear slot (NDS, ACO) $35–$95/lin ft · French drain $45–$120/lin ft
LA driveways must slope at least 1% (1/8 inch per foot) toward a legal drainage path per LADBS Green Building standards — not into the neighbor's yard, not toward the house foundation. Crown-and-slope with a 3-inch area drain at the low point works on most flat driveways. Linear slot drains (NDS Pro Series, ACO PowerDrain) are the cleaner modernist look and catch sheet flow across the full width. French drains are used when the driveway sheds into an adjacent landscape that needs percolation.
Curb cut — existing reuse vs new LADBS BOE permit
Reuse existing $0 · New curb cut $500 permit + $2,500–$8,000 install
LADBS Bureau of Engineering issues A-permits for new curb cuts (driveway aprons). The $500 permit plus $2,500–$8,000 in install (concrete apron, sidewalk tie-in, ADA detectable warning if near a pedestrian crossing) is a significant line item many homeowners miss. Widening an existing curb cut from 12 ft to 16 ft or 20 ft is the same A-permit. Cutting the curb without a BOE permit is a code violation that shows up on close-of-escrow inspection and gets dug up.
ADA access — accessible route from sidewalk to entry
Standard 2% max slope $0 additional · Ramp or lift $4K–$18K
If the driveway intersects an accessible route from public sidewalk to the main entry (rare on standard residential, common on ADU and duplex conversion), CBCh 11B applies — 2% max cross-slope on the accessible route, 5% max running slope without a ramp, 8.33% max running slope with a ramp. Most single-family driveways do not trigger this. ADUs and JADUs permitted under AB 1033 may trigger it if the ADU is a rental.

Cost bands by tier

Tier picks track with curb style, structural demand, and drainage sophistication. LA flat-lot replacements stay in budget or standard.

Tier	Total	Scope · Timeline

Standard — stamped concrete or simple paver	$24K–$48K	600–1,200 sqft 4–6 weeks Stamped concrete with release agent and sealer, OR Belgard interlocking pavers on 6-inch compacted base, linear drain at low point, pressure-treated edging, new area drain tied to existing sump or daylight exit, BOE curb-cut permit if widening.
Premium — architectural paver with linear drain	$48K–$75K	900–1,600 sqft 6–10 weeks Techo-Bloc or Pavestone Moduline pavers on 6-inch rebar concrete base (dual system — structural slab plus paver aesthetic), full linear slot drainage, integrated lighting, turnaround with retention curb, new BOE curb cut with ADA detectable warning.
Ultra — post-tensioned hillside or resin-set paver	$75K–$95K+	1,200–2,500 sqft 10–16 weeks Hillside post-tensioned slab OR resin-set European-import paver on full concrete sub-slab, PE-stamped structural and drainage, integrated EV charger conduit (Tesla Wall Connector or ChargePoint Home Flex 48A), heated driveway snowmelt rarely applicable in LA.

LADBS code and compliance

Driveways pull LADBS BOE for curb cuts, stormwater rules for discharge, and hillside review on sloped parcels.

LADBS BOE A-permit — curb cut
New curb cuts, widening existing cuts, or relocating a cut all need Bureau of Engineering A-permit ($500 + inspection). Min 3 ft from fire hydrant, 5 ft from storm drain inlet, 40 ft from arterial corner.
LADBS Green Building — drainage slope
Minimum 1% slope (1/8 inch per foot) to a legal drainage outfall. Cannot discharge onto adjacent property. MS4 stormwater rules may require permeable surface credits on new driveways over 500 sqft.
CBC §11B — ADA accessible route
If driveway intersects an accessible route from public way to dwelling entry (common on ADU and duplex), max cross-slope 2%, running slope 5% without ramp, 8.33% with ramp. Detectable warning strips at curb-cut entry.
LAMC Hillside Ordinance
Driveways on hillside-ordinance parcels have grading review, maximum 15% grade for first 20 ft from street, PE-stamped plan if retaining is required. Post-tensioned slabs allowed only with structural engineer of record.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
