ADU Design & Permitting Near Me in Pasadena - One Fixed Price, Permits Handled

ADU Design & Permitting Near You in Pasadena, CA

If you’re searching for our ADU Design & Permitting services near you, Ellery ADU Studio works throughout Pasadena and the surrounding San Gabriel Valley cities under one contract at one written price – drawings, permit set, and construction included. Nadia Ellery founded the studio in 2015, and every project starts with a written quote before any work begins, per Haven Standard Clause 1. Call (626) 427-9813 and a live person will answer – no voicemail, no callback queue.

Homeowners in Pasadena often reach us after getting a quote from a designer who hands them off to a contractor, or a contractor who subcontracts the drawings to someone they’ve never met. That gap between designer and builder is where most ADU projects get expensive and slow. Our one-contract model closes it: the same studio that draws the plans pulls the permit and builds the unit, so there’s no one to point fingers at when something doesn’t match the drawings. And if it doesn’t match – under our 365-Day Done Right Promise, we make it right. In writing. Before the project starts.

We’ve designed, permitted, and built more than 900 ADUs since 2015. Each one came with a written price before work started and a documented photo record when it was done. That’s not a marketing claim – it’s the paper trail we hand you at project close.

Pasadena’s permitting environment is specific. The city operates under its own municipal code layered on top of California’s statewide ADU statutes, and the Planning and Building Department on Garfield Avenue has its own submittal standards, plan check sequencing, and comment turnaround times. We know that office. We know what their plan checkers flag on a first-pass submittal and how to write the drawings so the comment list is short. That local knowledge is part of what you’re paying for – not just CAD files.

Fast, Local ADU Design & Permitting

When you call (626) 427-9813, you reach a live person who can schedule a Site Assessment – not a form submission that routes to a scheduling queue. For homeowners in Pasadena and nearby cities, we typically get eyes on the property within a few business days of your first call. The site assessment covers lot coverage, setbacks, utility connection points, and existing structure condition – the four things that determine whether your ADU budget is realistic before you spend a dollar on drawings.

From site assessment to a complete permit-ready drawing set, most Pasadena projects run eight to fourteen weeks depending on design complexity and the city’s current plan check queue. We track the city’s queue in real time and build that timeline into the written scope you receive at signing. No surprises on timeline, no surprises on price – that’s Haven Standard Clause 5.

We serve Pasadena and the broader San Gabriel Valley, including homeowners who contact us from Alhambra, Glendale, Arcadia, Temple City, Rosemead, Monterey Park, and El Monte. If your property is in one of these cities and you already have a written estimate from another firm, bring it – our Free Second Opinion review is available at no charge, and we’ll tell you exactly what it does and doesn’t include.

What the Single Contract Covers

Ellery ADU Studio offers five service lines, all available under the one-contract model:

• ADU Design & Permitting – full drawing set, Title 24 energy calculations, structural, and permit coordination through final inspection sign-off.
• Garage Conversion ADU – structural assessment of the existing slab and framing, drawings, permit, and conversion build. Garage conversions in Pasadena typically run $90,000-$160,000 all-in depending on finish level and utility separation requirements.
• New Detached ADU – site prep through framing, MEP rough-in, and finishes. Detached new-build ADUs on Pasadena lots generally range from $180,000-$340,000 depending on size, site conditions, and whether the project uses a prefab or modular system.
• Junior ADU & Interior Conversion – conversion of an existing interior space, typically lower permit complexity and faster city review.
• ADU Site Prep & Utilities – grading, drainage, utility trenching, and meter separation – the line items that catch homeowners off guard when they’re quoted separately by a contractor.

We also have direct experience specifying and coordinating prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie products within the same single contract. If a prefab system fits your site and budget, we’ll say so – and we’ll spec it into the drawings rather than leaving you to manage a separate vendor relationship.

How Pasadena’s ADU Rules Affect Your Project

California’s statewide ADU law sets a floor – maximum setbacks of four feet from rear and side property lines for most new detached ADUs, no owner-occupancy requirement through at least 2025, and streamlined approval for units under 800 square feet. Pasadena adds its own layer on top of that floor.

In the Bungalow Heaven Landmark District and parts of the Madison Heights and San Rafael neighborhoods, design review adds a step that doesn’t exist in most of the city. The Planning Commission has specific expectations about exterior materials and massing that affect how we draw the elevations. We’ve navigated that process enough times to know which design choices sail through and which ones generate a continuance.

Lot coverage matters in Pasadena’s R-1 zones more than homeowners expect. The city counts accessory structures toward your total lot coverage percentage, so if you have an existing pool house, large shed, or covered patio, we calculate the available envelope before we draw anything. Finding out you’ve already maxed your lot coverage at the Permit Application counter costs you the plan check fee and weeks of time. We find it at site assessment, at no extra charge, as part of your written scope.

Utility separation – specifically, whether your ADU needs its own water and electric meters – is a cost variable that’s often omitted from early contractor quotes. In Pasadena, the city requires separate utility service for ADUs in most configurations. We include utility coordination in the written price, not as a change order after permits are pulled.

Pricing: What ADU Design & Permitting Costs Near Pasadena

Design and permitting fees in the Pasadena market for a standard ADU project typically fall in the following ranges. These are all-in figures per Haven Standard Clause 1 – written before any work begins, not adjusted after the fact.

City permit fees for Pasadena are separate from design-build fees and are paid directly to the city. Plan check fees for a new detached ADU under 1,000 square feet currently run roughly $3,000-$6,500 depending on valuation. We include an estimate of city fees in your written quote so the total project cost is visible from day one.

If you have a written estimate from another firm, call (626) 427-9813 and ask for the Free Second Opinion. We’ll review what’s included, what’s not, and whether the scope matches what Pasadena’s building department actually requires.

The Haven Standard: What Every Client Receives

The Haven Standard is the operating agreement that governs every Ellery ADU Studio project. Three clauses matter most to a first-time ADU client:

• Clause 1 – Written Price Before Any Work Starts: You receive a written, line-item price before we draw a line or pull a permit. The price doesn’t change unless you change the scope.
• Clause 5 – No Surprises: The scope is locked at signing. No door-side upsells, no “we found something” change orders that weren’t foreseeable at site assessment.
• 365-Day Done Right Promise: If the finished ADU is not built to the permitted drawings, we make it right. This is a written commitment in your contract, not a customer service policy that exists until the project manager takes another job.

Every site visit generates a documented photo record – images of existing conditions, structural findings, utility locations. You receive that record, not a summary of how the meeting felt. If a future buyer, lender, or contractor asks what was behind the wall before the conversion, you have the answer in your project file.

Areas We Cover

Ellery ADU Studio’s primary service area covers Pasadena and the cities immediately surrounding it in Los Angeles County’s San Gabriel Valley. We actively take on projects in Alhambra, Glendale, Arcadia, Temple City, Rosemead, Monterey Park, and El Monte. Each of these cities has its own municipal permit process and HOA & Zoning Compliance requirements layered on top of California’s ADU statute, and our permit coordination covers all of them under the same single-contract model.

If your property is in one of these cities and you’re trying to figure out whether your lot qualifies for an ADU, the fastest path is a call to (626) 427-9813. A live person will walk through the basic lot coverage and zoning questions with you before you schedule anything.

For a deeper look at what the permit process looks like specifically in our home city, the ADU Design & Permitting in Pasadena page covers the city’s specific submittal requirements, plan check timelines, and the neighborhood-by-neighborhood design review considerations that affect projects in the Bungalow Heaven district and beyond.
