Hand-vetted contractors for kitchens, bathrooms, ADUs, and whole-home remodels across Baltimore Canyon, Baltimore Park, Heather Gardens, and Larkspur Landing. Free for homeowners.
Larkspur's housing stock spans more than a century. Baltimore Park and Old Downtown carry 19th-century cottages and early-1900s historic homes, Heather Gardens runs to remodeled 1940s cottages and bungalows, and the wooded eastern slopes of Mt. Tamalpais hold custom hillside homes in Baltimore Canyon and Madrone Canyon. The typical Larkspur house is a three-to-four-bedroom around 2,200 square feet, and the architectural mix moves from Victorian and Craftsman to California ranch, mid-century, and contemporary.
We match Larkspur homeowners with contractors who know the difference between a flat downtown lot and an irregular, heavily wooded canyon parcel. The projects we place here tend to be kitchen openings in older cottages, primary-bath expansions, detached ADUs and garage conversions, and full-scope remodels on canyon homes where hillside access and Wildland-Urban Interface assemblies drive the bid.
Realistic 2026 cost ranges based on the projects our contractors are actually pricing in Larkspur right now.
The most common request we field in Larkspur. In the early-1900s cottages of Baltimore Park and downtown, scope usually means opening a wall to a living or dining room, replacing dated cabinets, and re-running plumbing and electrical that predate modern code. Canyon homes often add structural work where the kitchen sits on a hillside-framed level.
Older Larkspur homes tend to have small, original bathrooms with tub-shower combos. Most projects we see expand into an adjacent closet or hallway to fit a curbless walk-in shower and double vanity. Full-scope primary baths land at the upper end; a hall-bath refresh sits lower.
Marin's certified housing element streamlined ADU pathways, so permitting moves faster than it did three years ago. On flat downtown and Baltimore Park lots a detached or garage-conversion ADU is straightforward; canyon parcels carry hillside foundation and access costs. Common uses are in-law suites, rental income, and a future downsize on the same lot.
Browse ADU models →Common for owners of older cottages and ranch homes who want to rebuild every system while keeping the character of the house. On canyon properties these projects often include drilled-pier foundation work, drainage upgrades, and Chapter 7A exterior assemblies. Down-to-studs remodels and second-story additions both happen here.
See how pricing works →Permits run through the City of Larkspur Community Development Department (Building and Planning Divisions) at 400 Magnolia Ave., Second Floor. The city accepts Building, Public Works, Fire, and Planning permits online through the eTRAKiT portal, and the permit counter is open Mondays and Wednesdays 9 to 5 and Thursdays 9 to noon. The Planning Division recommends contacting staff before you submit and will schedule in-person or online pre-application appointments, including when the counter is closed.
Portions of Larkspur sit in Cal Fire Fire Hazard Severity Zones, including Very High. The wooded canyons on the eastern slopes of Mt. Tamalpais (Baltimore Canyon, Sycamore Canyon, Blue Rock) carry the highest risk, and Central Marin Fire and the Marin Wildfire Prevention Authority run defensible-space (PRC 4291) and home-hardening inspections throughout the city, with 2025 rounds in Baltimore and Madrone Canyon. New construction and major remodels in designated zones must meet Wildland-Urban Interface (Chapter 7A) ignition-resistant building standards.
Old Downtown Larkspur along Magnolia Avenue is a locally designated H Zone overlay (1980) and a National Register district (listed 1982, NRHP #82000972); discretionary work there can go before the Heritage Preservation Board and the Planning Commission for design review. On older 1900s cottages and 1940s-50s stock, foundation bolting and cripple-wall shear paneling are common bid-day adders, and canyon hillside lots often add drilled-pier and drainage work. The San Andreas Fault offshore to the west is the dominant regional rupture hazard for Marin.
