AfterFast, Reliable Home Additions & ADU Across Silver Lake
The first thing you hit in Silver Lake is the hill. It’s not a backdrop, it’s the deal. After nearly three decades of framing rooms over cut-and-fill lots around the reservoir, we’ve learned that an addition on Micheltorena Street is a different animal than one on a flat grid street ten minutes away. The Hillside Ordinance kicks in the moment a slope tops 15 percent, and on most Silver Lake parcels it tops that fast. That means engineered caisson or deepened-pier foundations, retaining walls, and grading plans, all before a single wall goes up. If you’re weighing a home addition or ADU in Silver Lake, call us at (877) 610-1318. We’re the Home Additions & ADU team that reads the lot before we quote it.
Why Barrett & Sons Construction Is Silver Lake’s Preferred Home Additions & ADU Company
We’re not a franchise dispatching strangers. Tom Barrett’s sons run the crews, and Tom answers the phone. That matters more in Silver Lake than almost anywhere else, because the work here is unforgiving. A 1928 hillside bungalow with a cripple-wall foundation doesn’t let you guess. Neither does a 1949 Neutra-style flat roof with a parapet that’s been catching Santa Ana wind for seventy years. Homeowners here tell us stories about contractors who bid blind, pulled a standard addition permit, and got a stop-work correction the day grading started. We’ve heard it enough that we walk every hillside parcel in 90026 with a civil engineer before we ever hand you a number. Our Silver Lake customers leave reviews that mention one thing over and over: the price on the contract matched the price at the end. Written change orders, permits pulled, inspections signed. Look up Tom’s license number yourself. He publishes it.
Our Home Additions & ADU Services in Silver Lake
ADU Design & Permitting
Starting an ADU in Silver Lake means getting the design through a plan check that treats hillside lots differently than flat ones. We handle the architectural set, the civil grading plan, the structural calcs for caissons or piers, and the permit submittal. We’ve shepherded ADUs through the city for accessory units above garages on Micheltorena, behind bungalows near the reservoir, and tucked into upslope corners off Silver Lake Boulevard. The paper gets done before the trenching starts. That’s the order it needs to happen in.
Garage Conversion ADU
Most garages in Silver Lake were built for a single car and a workbench, not for living. Conversion means upgrading the seismic connection to the main house, pouring a proper floor over the old slab, insulating the walls, and often adding sheer panels because the garage sits on the downhill side. A garage conversion ADU in Silver Lake generally runs $90,000 to $220,000 depending on whether you keep the original footprint or extend it. We’ll quote the line items in writing.
New Detached ADU
A new detached ADU on a Silver Lake hillside lot is a small house with a foundation problem. Caisson drilling, retaining walls, utility trenching upslope, and sometimes a crane for panel placement all factor in before you pick a paint color. We estimate new detached ADUs in this neighborhood from $90,000 to $220,000, with a full ADU construction scope included. The site prep and utilities line is where cheaper bids quietly fall apart. We don’t let them.
Junior ADU & Interior Conversion
For a home that already has a finished but underused room, a junior ADU is the fastest path. We convert attached spaces into legal JADUs under the state’s relaxed standards, which helps on hillside lots where adding square footage triggers the Hillside Ordinance. Interior conversions avoid most of the grading and foundation work entirely. The kitchenette, separate entrance, and egress requirements are what we focus on, and we handle all Home Additions & ADU in Silver Lake jobs with permits pulled and inspections signed.

Trusted Brands We Service in Silver Lake
We don’t install mystery materials off a van. For windows and doors on Silver Lake additions, we work with Simonton for clean sightlines and thermal performance that matters when the Santa Anas blow through the canyons. For impact-rated packages on exposed hillsides, PGT gives you a frame that holds up to wind-driven rain. We keep common sizes and parts accessible for Silver Lake customers, so a replacement sash or a door threshold doesn’t turn into a three-week wait. Our Silver Lake clients get named brands they can look up, not whatever the supply house had on sale.
Common Home Additions & ADU Problems We See in Silver Lake Homes
- Stop-work corrections on hillside permits. A contractor pulls a standard addition permit on a sloping lot, and the inspector flags the grading plan as insufficient. The project sits for weeks while a civil engineer gets brought in late. The correct order is the grading plan first, and that’s how we work in the 90026 zip.
- Unbolted or cripple-wall foundations from the 1920s and 1930s. Adding load to a post-and-beam house with an original concrete-block foundation is a seismic risk. We assess the bolting and sheer transfer before designing any second-story or addition scope.
- Wind-driven rain at flat-roof parapets and deck ledgers. Silver Lake’s hillside microclimate channels Santa Ana winds through the canyons each fall. Flat-roof parapets and second-story deck connections that were watertight in a flat neighborhood leak here. We detail those junctions to shed water under wind pressure, not just gravity.
- HPOZ complications on architecturally sensitive homes. Silver Lake holds one of the densest concentrations of 1920s to 1950s California modernist homes in the country. Even modest structural work can trigger Historic Preservation Overlay Zone review. We prepare for that review before demo day, so it doesn’t ambush the schedule.

FAQs - Home Additions & ADU in Silver Lake
How quickly can you get to a Silver Lake home for an estimate?
We schedule estimates in Silver Lake within a few days in most cases, and because dispatch and scheduling are coordinated from our Los Angeles office, we can often get someone to a Silver Lake lot the same week you call. Call (877) 610-1318 and a live person answers.
Do you cover all Silver Lake neighborhoods?
Yes, we cover the full 90026 zip, from the reservoir’s edge up through the hillside streets, and all surrounding Silver Lake neighborhoods. We don’t cherry-pick flat lots.
Does a Silver Lake hillside addition cost more than one in Echo Park or Hollywood?
Typically yes. A room addition in Silver Lake runs $45,000 to $130,000, and the hillside lots push the high end because of foundation engineering, retaining walls, and grading plans that flat neighborhoods rarely need. That’s not markup. That’s the cost of doing it right on a slope.
Do you pull permits for ADU work in Silver Lake?
Every eligible job gets permits pulled and inspections signed. On Silver Lake hillside lots, that means a licensed civil engineer’s grading plan before the permit submittal in most cases. The inspector works for you, not for us, and that’s the way we like it.
What warranty do you offer on a Silver Lake addition?
Every completed job carries our 90-Day Done Right Promise, written on the contract. If something’s not done right, one call brings Tom back to make it right. We don’t bury the guarantee in fine print.
