ADU Design & Blueprints in Burbank, CA

ADU Design & Blueprints in Burbank, CA

ADU Design & Permitting in Burbank means producing a permit-ready drawing set – site plan, floor plans, elevations, electrical layout, and structural notes – that the City of Burbank’s Building & Safety Division will stamp and approve. Without that set, nothing gets built legally. At Ellery ADU Studio Burbank, we’ve been doing this since 2015, and every drawing package we produce is priced in writing before a single line goes on paper, per Haven Standard Clause 1.

If you’re trying to figure out what a full blueprint package actually costs in this market, or why the permit set your neighbor’s contractor handed over got rejected twice, this page answers both questions with numbers attached. Our ADU Design & Permitting in Burbank parent service covers the full arc from zoning analysis through final inspection sign-off – this page focuses on the design and drawing phase specifically.

When You Need ADU Design & Blueprints

• You own a lot in Burbank and want to add rental income or a family unit. Neighborhoods like Magnolia Park, Rancho, and the Chandler Estates area have a high concentration of 1940s-1960s single-family homes sitting on lots that can accommodate a detached ADU of 400-800 square feet – but the city requires a code-compliant drawing set before a permit application can even be filed.
• Your contractor gave you a price but no permit set. In Burbank, a contractor who bids a job without a stamped, city-approved drawing set is essentially pricing work that may never pass inspection. The drawings have to come first, and they have to be site-specific – Burbank’s 5-foot rear setback rule and its R-1 lot coverage cap of 40% mean generic plans from another jurisdiction will not work here.
• You had drawings done and the city kicked them back. Burbank’s plan check process flags missing fire-separation details, incorrect egress window dimensions, and underspecified electrical panels more often than homeowners expect. If you’re on your second or third round of corrections, a fresh set of eyes on the drawing package – with knowledge of what local plan checkers actually look for – is faster than another round of revisions.
• You’re considering a prefab or modular unit and need site-specific engineering to match. Prefab systems like Cover or Abodu ship with manufacturer drawings, but Burbank still requires a site-specific foundation plan, utility connection details, and a soil report in many cases. Those documents have to be coordinated with the manufacturer’s drawings before the city will accept the package.
• You want to convert your garage but aren’t sure what’s structurally involved. Burbank’s older garage slabs – many poured in the 1950s at 3.5 inches – sometimes fall short of the 4-inch minimum for a habitable conversion without a structural upgrade. The drawing set has to document the existing condition and specify the remedy before the permit office will proceed.
• You need drawings that actually match what gets built. The most common ADU dispute in Burbank isn’t price – it’s a finished unit that doesn’t match the permitted drawings, triggering a stop-work order or a failed final inspection. Our 365-Day Done Right Promise means that if the finished ADU isn’t built to the permitted drawings, we make it right, in writing, before the project starts.

Our ADU Design & Blueprints Process

1. Site Survey and Zoning Verification

   Before any drawing starts, we measure the lot, confirm the existing structure dimensions, and pull the current zoning file from the City of Burbank. We check the lot’s R-1 or R-2 classification, the existing lot coverage percentage, and whether any prior permits on the property created conditions that affect HOA & Zoning Compliance and ADU eligibility – an unpermitted garage conversion from 2003, for example, shows up here. You receive a written summary of what we found, not a verbal overview.

2. Written Scope and Price Before Any Design Work

   Under Haven Standard Clause 1, we produce a written price for the complete drawing package before any design work begins. The scope document names every sheet in the permit set – site plan, floor plans, all four elevations, cross-section, electrical plan, and structural notes – along with the engineering deliverables required for your specific unit type. No surprise add-ons at submission.

3. Schematic Design and Client Review

   We produce a schematic layout – floor plan and basic massing – and walk through it with you before moving to construction documents. For detached ADUs in Burbank, this is also the stage where we confirm the unit’s position relative to property lines and confirm the setback compliance: 5 feet from the rear and side property lines for most R-1 lots, with variations near alleys or in hillside zones north of the 134. Changes at the schematic stage cost nothing. Changes after construction documents are drafted cost time and money, so we take this step seriously.

4. Construction Document Set

   This is the full permit set: dimensioned floor plans at 1/4″ scale, four-elevation drawings, a site plan showing the ADU footprint relative to all property lines and existing structures, a cross-section showing ceiling height and roof pitch, an electrical plan with panel schedule, a structural detail sheet, and the Title 24 energy compliance documentation California requires for all new habitable space. Every sheet carries the project address, the applicable Burbank Municipal Code sections, and the licensed design professional’s information. This is the document set you own – it stays with your property record.

5. Plan Check Submission and Correction Management

   We submit the package to Burbank Building & Safety and track it through plan check. Burbank’s current over-the-counter plan check is available for ADUs under 500 square feet that meet standard setbacks – larger or more complex projects go through a standard review cycle that typically runs 3-6 weeks for a first submittal. When the city returns correction comments, we respond to them as part of the same scope. You don’t pay a separate fee every time a plan checker asks for a clarification on a fire-wall detail.

6. Approved Permit Set Delivered

   When Burbank stamps the drawings, you receive the full approved permit set in digital and paper form. If your project is part of our one-contract design-build model, construction begins from those exact drawings – no handoff gap, no version confusion. The photo record of the construction phase documents compliance with the permitted set at each inspection stage.

ADU Design & Blueprints Pricing in Burbank

How Much Does ADU Design & Permitting Cost? (2026 Price Guide) - Burbank, CA fees in Burbank’s ADU market range from around $8,000 for a straightforward garage conversion drawing set to $22,000 or more for a new two-story detached ADU with complex structural requirements or a hillside lot condition. The table below reflects what we see in this market – not a national average.

These are design and blueprint fees only – separate from construction costs. When Ellery ADU Studio handles your project under the one-contract design-build model, design fees are included in the all-in written price you receive before work starts. The written price covers drawings through final inspection, with no separate billing event when the permit gets issued.

What moves the fee up within any range: a lot with a recorded easement that affects buildable area, an older property with no existing as-built drawings (we have to measure and document the existing condition before designing the new one), a hillside lot in the Verdugo Woodlands or Sunset Canyon area where Burbank’s grading and geology requirements add engineering sheets to the set, or a prefab unit that requires close coordination with the manufacturer’s engineering team.

What keeps the fee toward the lower end: a flat, standard R-1 lot in the Magnolia Park or Equestrian District area with a clear permit history, a straightforward garage conversion on a slab that already meets the 4-inch minimum, and a unit under 500 square feet that qualifies for Burbank’s expedited over-the-counter plan check.

Every price we quote is written down and locked before any design work starts – Haven Standard Clause 1, no exceptions. If you have a written estimate from another firm and want a second opinion on the scope or the number, that service is free. Call (747) 322-4648 and we’ll review what you have.

What the Burbank Blueprint Set Actually Contains

A lot of homeowners in Burbank have been handed a “set of plans” that turned out to be three pages and a sketch. A permit-ready ADU drawing set for Burbank Building & Safety is a specific, multi-sheet document package. Here’s what a complete set includes:

• Site Plan: Shows the lot boundaries, the ADU footprint, all setback dimensions, the existing structure, and the utility connection points. Burbank requires this at a scale that clearly shows compliance with lot coverage limits.
• Floor Plans: Dimensioned at 1/4″ = 1′-0″, showing room layout, door and window locations with sizes, fixture placement, and egress compliance. Burbank’s Building & Safety checks window dimensions against California Residential Code Section R310 for egress in sleeping rooms.
• Elevations (all four sides): Show exterior finish materials, roof pitch, finished floor to plate height, and window/door header heights. If you’re specifying James Hardie fiber cement siding – which handles Burbank’s dry summer heat and Santa Ana wind cycles better than wood – the elevation sheet names the product and the installation method.
• Building Cross-Section: Shows interior ceiling height, roof assembly, insulation type and R-value, and floor/foundation assembly. Required by Burbank for any new habitable structure.
• Electrical Plan and Panel Schedule: Shows all circuits, outlet locations, panel amperage, and the smoke/CO detector placement California requires in every sleeping room and on every floor.
• Structural Details: Foundation type and dimensions, hold-down hardware, shear wall locations, and beam/header schedules. Hillside lots north of the 210 and 134 interchange require additional details.
• Title 24 Energy Compliance Report: California’s mandatory energy calculation for all new conditioned space, covering insulation, glazing, mechanical systems, and lighting. Burbank accepts the standard CF1R/CF2R documentation package.

FAQs – ADU Design & Blueprints in Burbank

How long does it take to get ADU blueprints approved in Burbank?

A complete, code-compliant ADU drawing set for a straightforward project typically takes 4-6 weeks to produce from the start of design to a ready-to-submit package. Burbank Building & Safety’s plan check for ADUs under 500 square feet can sometimes be handled over the counter, but most projects go through the standard review cycle, which currently runs 3-6 weeks for first submittal and another 1-3 weeks per correction round. Budget 2-4 months from design kickoff to approved permit if your project is a standard detached or garage conversion ADU. More complex projects – hillside lots, two-story units, prefab coordination – run longer. We track your application through each stage and handle correction responses without a separate billing event.

Can I use a prefab ADU and still need a full drawing set in Burbank?

Yes. Prefab manufacturers like Cover and Abodu provide their own structural and architectural drawings, but Burbank still requires a site-specific permit set that shows your property’s lot lines, setbacks, foundation design, and utility connections. The manufacturer’s drawings become part of the package, but they don’t replace the site-specific documents. We coordinate directly with the manufacturer’s engineering team to produce a combined package that Burbank’s plan checkers can review without gaps. Call (747) 322-4648 to discuss what your specific prefab unit requires.

What’s the difference between a design fee and an all-in ADU cost?

The design and blueprint fee covers the drawing production and permit management phase only – it doesn’t include construction. An all-in ADU cost includes design, permits, site prep, foundation, framing, MEP (mechanical, electrical, plumbing), finishes, and the city’s final inspection. In Burbank, a new detached ADU typically runs $280,000-$420,000 all-in, design through final inspection, depending on size and finish level. A garage conversion typically runs $130,000-$220,000 all-in. When Ellery ADU Studio handles your project under the one-contract model, both phases are in a single written price – no separate design contract, no separate build contract, no gap between what the drawings say and what the builder does. Call (747) 322-4648 for a written price specific to your lot.

What happens if Burbank rejects my drawings during plan check?

Plan check corrections are normal – most ADU projects in Burbank receive at least one round of comments, particularly around fire-separation details for garage conversions and egress requirements for sleeping rooms. At Ellery ADU Studio, correction responses are included in the original scope. We don’t bill you a separate fee each time the plan checker requests a revised detail sheet. Under Haven Standard Clause 1, the written price you receive before work starts covers the drawing set through permit issuance. If a correction requires a genuine scope change – something materially different from the original design – we document that in writing before proceeding. Call (747) 322-4648 if you’re already mid-process with a set that’s been rejected and need a second opinion on how to move it forward.
