ADUs & Additions in Silver Lake
Detached ADUs, garage conversions, room additions and second stories. Designed, permitted and built by our own crews.
ADUs & Additions built for Silver Lake properties
Silver Lake takes its name from the reservoir at its center, and its streets bend around that water and the hills that hold it. Public stairways climb between those streets, and many houses are set into the slope or perched at its edge, including modernist work by Schindler, Neutra, Soriano and Lautner scattered through the hills. That setting shapes outdoor projects on its hillside lots: a pool, a terrace or a backyard ADU has to earn its level ground through retaining and drainage, then sit gracefully beside a house that may be architecturally significant. Hillside grading rules and a Very High Fire Hazard Severity Zone cover much of the neighborhood, so both belong in the first conversation about design.
Hillside lots around the Silver Lake and Ivanhoe reservoirs are often steep, with houses set into the slope or perched at its edge, and many modern houses turn toward the rear to take in the view. Blocks on either side of Sunset Boulevard began as early streetcar tracts, with relatively shallow setbacks, little provision for the car, and Craftsman and Spanish Colonial Revival houses mixed with a smaller share of multi-family buildings such as bungalow courts.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054.
Permits in Silver Lake: Private pools in the City of Los Angeles are permitted through a Combined Building-Mechanical permit, while pools serving more than two dwelling units need separate building, electrical, plumbing and mechanical permits. Using a City of Los Angeles standard plan on file with LADBS reduces plan check time. Much of Silver Lake, including the hills around the reservoirs, is mapped in both the Hillside Area, where the Baseline Hillside Ordinance caps grading and import/export quantities, and the Hillside Grading Area, where a pool needs its own LADBS grading permit. Most of the neighborhood also falls in a Very High Fire Hazard Severity Zone on CAL FIRE's March 2025 local responsibility area map. No Historic Preservation Overlay Zone covers Silver Lake, but the city's SurveyLA historic resources survey recorded the Silver Lake Residential Historic District, more than 1,000 properties anchored by the Moreno Highlands tract on the reservoir's west side.
Permit details checked September 2026 against LADBS and LA City Planning. Rules change, so we confirm them again for your parcel.

Local Conditions
What building in Silver Lake actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Silver Lake projects.
Steep hillside lots around the reservoirs, some once considered unbuildable, often need retaining walls and engineered foundations before a pool or terrace has level ground
Curving streets and public stairways thread the hills, so equipment access, staging and haul-off need to be planned before work begins
Pockets of the hillsides are mapped by the California Geological Survey as earthquake-induced landslide zones, where the city may require a geologic or soils investigation before issuing permits
Much of the hills is mapped as both a Very High Fire Hazard Severity Zone and a city Fire Brush Clearance Zone, which brings clearance, planting and material choices into the design early
Investment
What this costs in Silver Lake
Real Southern California ranges, not a teaser number. Every project is priced line by line after we have seen the site.
Detached ADU
$150,000 to $400,000+
What moves it: square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build
Garage conversion ADU
$80,000 to $180,000
What moves it: whether the existing slab and framing meet current code, how far utilities have to run, and the finish level of the kitchen and bathroom
Plans, drawings and permit management
$4,500 to $25,000+
What moves it: project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved
Your number depends on your lot, your access and your finishes. We walk the site, then price every line so you can see exactly where the budget goes.

Your Silver Lake project, step by step
Feasibility
We check lot size, setbacks, utilities and access to confirm what your property will actually support.
Design & 3D
Layout, elevations and finishes, modeled in 3D so you approve the unit before submittal.
Plans & Permits
We prepare the full drawing set, handle engineering and Title 24, and manage the city submittal and corrections. In Silver Lake that submittal goes to Los Angeles Department of Building and Safety (LADBS).
Foundation & Framing
Site prep, foundation, framing and dry-in by our own crews.
Systems & Finishes
Electrical, plumbing, HVAC, insulation, then kitchen, bath and interior finishes.
Final Inspection
We pass final inspection, walk the unit with you and hand over the keys.
Silver Lake Questions
Common questions from Silver Lake homeowners
Who issues the permits for this work in Silver Lake?
Los Angeles Department of Building and Safety (LADBS). Private pools in the City of Los Angeles are permitted through a Combined Building-Mechanical permit, while pools serving more than two dwelling units need separate building, electrical, plumbing and mechanical permits. Using a City of Los Angeles standard plan on file with LADBS reduces plan check time. Much of Silver Lake, including the hills around the reservoirs, is mapped in both the Hillside Area, where the Baseline Hillside Ordinance caps grading and import/export quantities, and the Hillside Grading Area, where a pool needs its own LADBS grading permit. Most of the neighborhood also falls in a Very High Fire Hazard Severity Zone on CAL FIRE's March 2025 local responsibility area map. No Historic Preservation Overlay Zone covers Silver Lake, but the city's SurveyLA historic resources survey recorded the Silver Lake Residential Historic District, more than 1,000 properties anchored by the Moreno Highlands tract on the reservoir's west side. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.
What makes building in Silver Lake different?
Hillside lots around the Silver Lake and Ivanhoe reservoirs are often steep, with houses set into the slope or perched at its edge, and many modern houses turn toward the rear to take in the view. Blocks on either side of Sunset Boulevard began as early streetcar tracts, with relatively shallow setbacks, little provision for the car, and Craftsman and Spanish Colonial Revival houses mixed with a smaller share of multi-family buildings such as bungalow courts. One local condition that shapes the work: Steep hillside lots around the reservoirs, some once considered unbuildable, often need retaining walls and engineered foundations before a pool or terrace has level ground.
Which parts of Silver Lake do you work in?
All of it, including Moreno Highlands, Ivanhoe, Sunset Junction and Neutra Colony. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What does an ADU or addition cost in Silver Lake?
Detached ADU: generally $150,000 to $400,000+ across Southern California. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does an ADU take start to finish?
Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.
Is a garage conversion cheaper than a detached ADU?
Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.
Can I rent the ADU out?
California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.
Do you handle the permits?
Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
