AfterFast, Reliable Home Additions & ADU Across Old Fig Garden
Home additions and ADU construction in Old Fig Garden run $45,000 to $130,000 for most room additions, $90,000 to $220,000 for a new detached ADU, and $30,000 to $80,000 for a garage conversion.

Barrett & Sons Construction has worked these streets since 1998, and Tom Barrett or one of his sons is on-site most days. If you want a straight answer about what it takes to add square footage in this neighborhood, call (877) 610-1318.
Why Barrett & Sons Construction Is Old Fig Garden’s Preferred Home Additions & ADU Company
Old Fig Garden is not a neighborhood where you send a crew that has never seen a 1930s pier-and-beam foundation. The homes here were built between the 1920s and 1950s, mostly Spanish Colonial Revival, Mediterranean, and Tudor Revival styles. Original plaster walls, aging sewer lines, and mature fig tree roots don’t show up on a Google Street View. They show up when you start digging.
Our crews know what happens when a foundation trench meets a valley oak root. We’ve pulled permits for ADU work in ZIP code 93704, dealt with the city’s tree-protection reviewers, and scheduled pours at 6:00 a.m. before the summer heat hits 100°F. Tom Barrett publishes his name, address, and license number. You can look it up before you sign anything. That’s how we’ve done business for 29 years.
Every price change comes as a written change order before work happens. Permits are pulled and inspections signed on every eligible job. And when we finish, the 90-Day Done Right Promise is on the contract in plain language: if it’s not done right, one call brings Tom back.
Key Takeaways:
- Home additions in Old Fig Garden typically run $45,000-$130,000; ADU construction $90,000-$220,000; garage conversions $30,000-$80,000.

Our Home Additions & ADU Services in Old Fig Garden
Every project starts with the same question: what will actually work on your lot? In Old Fig Garden, that answer is different than it is in the newer subdivisions east of the 41. Our Home Additions & ADU team plans around tree roots, historic facades, and narrow side yards. Here’s what we handle most often around here.
ADU Design & Permitting
An ADU on a 1920s Old Fig Garden lot almost always triggers a pre-construction root-zone assessment if there’s a mature tree anywhere near the footprint. We handle that step before drawings go to the city. It saves weeks of back-and-forth and keeps the project from stalling at the permit counter. We also produce full permit sets with structural drawings that reflect the actual conditions of your house, not a template from a plan mill.
Garage Conversion ADU
Detached garages in Old Fig Garden were built for Model A Fords, not for living space. Most need new slab insulation, upgraded electrical service, and often a roof restructure. If the garage shares a wall with the neighbor’s garage, we review the structural load transfer before rough-in. A sketchy party-wall agreement is the fastest way to fail an inspection. We don’t let that happen.
New Detached ADU
Building a detached ADU behind a 1930s Tudor on a wide Fig Garden lot takes careful siting. We stake the footprint with the tree canopy in mind, and when the drip line is too close, we adjust the plan before the excavator ever rolls in. On a recent project off East Holland Avenue, we staged a detached ADU without disturbing two mature valley oaks. We used a boom lift over the driveway instead of trenching across the root zone, and poured at 6:00 a.m. to beat the heat.
Junior ADU & Interior Conversion
Old Fig Garden has plenty of large homes where a tucked-away wing, a former maid’s quarters, or an oversized utility room can convert into a legal junior ADU. The catch is the original plaster-and-lath walls. We keep them intact where possible, which saves you from full seismic retrofit triggers and preserves the period character. A junior ADU in a 1920s home is often the fastest path to rental income per dollar spent.

Trusted Brands We Service in Old Fig Garden
We install products you can look up by name, not mystery brands off a van. For window and door packages on Old Fig Garden additions, we frequently spec Simonton and Ply Gem, both of which carry lines that fit the historic profiles common around here. On impact-rated openings where the summer heat and sun exposure are hard on materials, PGT is a frequent choice. We order direct and schedule delivery to match the access constraints of your driveway, because on a gated estate lot, a missed drywall delivery doubles the handling cost.
Common Home Additions & ADU Problems We See in Old Fig Garden Homes
- Ignoring tree-root zones during excavation. Trench or grade near a mature fig or valley oak without an arborist report and you risk a stop-work order from the city’s tree-protection enforcement. This is the number one delay factor on ADU foundations in Old Fig Garden.
- Assuming suburban-style access. A narrow driveway or gated courtyard on a 1920s estate lot can block a concrete pump or drywall delivery. We plan material handling before the quote is final, because moving Sheetrock by hand through a side gate costs real money.
- Party-wall agreements done on a handshake. A shared wall with an attached garage ADU stalls at inspection if the neighbor’s side isn’t reviewed for structural load transfer before rough-in. We get the written agreement and the engineering review done early.
- Original plaster walls cut without a plan. Plaster-and-lath interiors hide wiring, lead paint, and sometimes structural cracks from 80 years of settling. We open walls carefully and only where the design requires it, which keeps costs down and your home’s character intact.
Pricing for Home Additions & ADU in Old Fig Garden, CA
Here’s the honest picture for Home Additions & ADU in Old Fig Garden. A straight room addition runs $45,000 to $130,000 depending on square footage, foundation work, and whether we’re matching period detailing on the exterior. A detached ADU from excavation to certificate of occupancy lands between $90,000 and $220,000. Garage conversions sit at $30,000 to $80,000. What moves the number on these lots: tree-root mitigation, plaster retention versus removal, soil conditions under 1920s-era slabs, and access for equipment. We write every allowance and every change order down before work happens. The allowance that isn’t on paper is a surprise waiting for a date.

FAQs - Home Additions & ADU in Old Fig Garden
Yes, in most cases it does. Old Fig Garden’s tree-protection ordinance requires a pre-construction root-zone assessment and arborist sign-off before any excavation for an ADU or addition when a protected tree is near the footprint. We arrange the arborist, set the foundation depth around the root findings, and file the paperwork with the city. Call (877) 610-1318 if you want us to check your lot before you commit to a design.
Often yes, if the conversion stays within the existing building envelope and we retain the original walls as shear elements. Cutting new openings through plaster-and-lath can trigger structural review, but keeping the walls intact and adding light-touch finishes usually avoids a full seismic retrofit. We assess this on every Old Fig Garden junior ADU before recommending a scope.
Construction noise in Old Fig Garden is generally limited to weekday daytime hours, and the neighborhood is quiet enough that even legal hours draw attention. We keep the noisy work to mid-morning starts, coordinate deliveries to avoid school drop-off traffic on Van Ness, and talk to the neighbors before the project starts. It keeps the job moving and the block friendly.
We use smaller, staged material drops, load-out as we go, and run a daily end-of-day cleanup. On tight Old Fig Garden lots where a full roll-off won’t fit, we schedule debris removal in smaller containers and keep materials on our trucks instead of piled in the driveway. Your neighbors will tell you whether we did it right.
It should, and we make sure it does. If your addition touches a shared wall, the structural load transfer has to be reviewed on the neighbor’s side before rough-in. We get the written party-wall agreement and the engineering review done before the permit application moves forward. Skipping this is what turns a $60,000 garage conversion into a stalled inspection and a stop-work notice.
