Why Homeowners Choose
iarchstudios
Homeowners throughout Wilshire and the surrounding Los Angeles neighborhoods work with iarchstudios for thoughtful architectural design, realistic project guidance, and permit-ready plans tailored to local requirements. Our team regularly works with LADBS and understands the permitting challenges that can arise throughout Los Angeles, from zoning reviews and plan check corrections to utility coordination and site-specific design limitations.
We specialize in creating plans that are designed not only for aesthetics, but also for constructability and city approval. Every property is different, especially throughout Mid-Wilshire where many homes feature unique lot conditions, older structures, and varying zoning overlays. We take the time to evaluate each site carefully to help homeowners understand what is feasible before moving into the design process.
Our services include architectural planning, engineering coordination, permit submittals, and responding to city corrections throughout the approval process. We focus on creating realistic project timelines and clear communication so clients can move forward with confidence from concept to permit approval.
ADU Design in Wilshire
Wilshire and Mid-Wilshire continue to see growing demand for ADUs, garage conversions, and property additions as homeowners look for ways to maximize existing lots and increase long-term property value. iArch Studios provides custom ADU design services for a wide range of property types throughout the area, including detached ADUs, attached ADUs, garage conversions, and second-story additions.
Many properties throughout Wilshire, Hancock Park, and nearby Koreatown feature older Los Angeles housing stock with detached garages, alley access, and underutilized rear yard space that may provide strong ADU opportunities. Our team helps homeowners evaluate potential layouts while considering setbacks, parking requirements, utility locations, and overall site constraints.
For properties located near transit corridors, homeowners may also qualify for parking exemptions under California ADU regulations. Multifamily properties throughout Mid-Wilshire may additionally qualify for multiple ADUs depending on existing conditions and zoning allowances. We work closely with property owners to identify practical design solutions that align with both city regulations and long-term project goals.
SB9 Opportunities in Wilshire
California SB9 regulations have created new opportunities for homeowners throughout Los Angeles to maximize residential properties through lot splits and additional housing units. In neighborhoods throughout Wilshire and Mid-Wilshire, SB9 may allow qualifying single-family lots to be split or developed with additional units depending on zoning and site conditions.
Our team assists homeowners with preliminary zoning reviews, feasibility analysis, site planning, and architectural design for SB9 projects throughout Los Angeles. We evaluate factors such as lot dimensions, access requirements, setbacks, utility coordination, and existing structures to determine whether a property may qualify for SB9 development opportunities.
SB9 projects can create opportunities for duplex conversions, additional rental income, multigenerational housing, or long-term property appreciation. Because every site is unique, early planning and zoning analysis are critical before moving into the design and permitting process.
Common Challenges for Wilshire Properties
Properties throughout Wilshire and Mid-Wilshire often present unique architectural and permitting challenges due to the age and density of the surrounding neighborhoods. Many lots feature narrow site conditions, alley access limitations, aging utility infrastructure, or older foundations that require careful coordination during the design process.
Historic preservation overlays and specific planning requirements may also impact certain properties throughout the area, particularly near Hancock Park and surrounding historic neighborhoods. In addition, some sites may include sloped terrain, irregular lot configurations, or limited access for construction.
Our team regularly works through common LADBS plan check corrections, zoning comments, and engineering coordination requirements that arise during the permitting process. By identifying potential issues early, we help homeowners reduce delays and move projects forward more efficiently.
Frequently Asked Questions
Architectural fees in Los Angeles and surrounding cities (Glendale, Burbank, Pasadena) typically range from 5%–10% of the total construction cost for residential projects. For smaller projects like ADUs or garage conversions, some architects may offer a flat-rate design package. Hiring an architect ensures your plans meet city code and pass permit approval smoothly.
Adding an ADU (Accessory Dwelling Unit) or a home addition in Los Angeles often increases property value based on the average price per square foot in your neighborhood. For single-family homes and properties with fewer than four units, an ADU not only raises resale value but can also generate rental income, making it one of the best investments for California homeowners.
Most architectural projects in California follow these stages:
Consultation & Site Analysis – reviewing property conditions, zoning, and project goals.
Rough Design – initial sketches and layout concepts.
Design Development – refining the floor plans, elevations, and materials.
Prepare Documents – preparing detailed plans for permits and builders.
Permit Submittal – submitting to LADBS (Los Angeles Department of Building & Safety) or your local city’s planning department.
Construction Administration – optional, where your architect coordinates with contractors during the build.
In Los Angeles, Glendale, and Burbank, plan check approval usually takes 3–6 months. Timelines may be longer if your property is in a Historic Preservation Overlay Zone (HPOZ), hillside area, or near utility easements. Working with an experienced architect can speed up approvals by submitting a complete, code-compliant set of plans.
A wall can be removed only if it’s not load-bearing. Load-bearing walls support the roof, ceiling, or floor above and require a new beam or structural support to replace them. An architect or structural engineer in Los Angeles can determine if your wall is load-bearing and prepare safe, permit-ready plans for removal.
You can check eligibility for SB9 lot splits or duplex projects in Los Angeles by using the ZIMAS (Zone Information & Map Access System) tool or your city’s zoning map. Properties in very high fire zones, historic overlays, or environmental restrictions may not qualify. A licensed architect can review your parcel and confirm if SB9 applies to your property.
Under California state law, every single-family property has the right to build an ADU up to 800 sq. ft., even if local zoning would otherwise restrict it. In Los Angeles, detached ADUs can be as large as 1,200 sq. ft., depending on Residential Floor Area (RFA) limits. Glendale and Burbank also follow California ADU law but may enforce local design standards.
Always check with a local architect to confirm the latest ADU regulations for your city.
Los Angeles – Two-story ADUs are allowed if they meet height limits (generally up to 25 ft. for detached units).
Glendale – Detached ADUs are limited to single-story, though attached conversions may be possible.
Burbank – A second story is usually permitted only above an existing structure, such as a garage.
