Mt Washington Exterior + Hillside Design 2026 | CSLB #1105249
Mt Washington exterior work is mostly a hillside engineering problem dressed up as a design problem. The Baseline Hillside Ordinance §B and §C define what you can build on slope, retaining walls over 4 feet need structural permit and a soils report, narrow private streets constrain equipment and deliveries, and the Mid-Century post-and-beam vocabulary deserves to be honored on the exterior the same as the interior. We design and build to all of it. NPLD, CSLB #1105249, 200+ LA builds, real Mt Washington exterior cost band $30K to $170K.
Exterior Design Questions Homeowners Ask About Exterior Design in Mount Washington
Retaining walls over 4 feet - what's required?
Structural permit, soils engineer report, drainage detail, subdrain behind wall. Real engineering, not stacking blocks.
What's BHO §B and §C?
Baseline Hillside Ordinance zones, constrain new construction on slope. Affects decks, accessory structures, additions. We pull the overlay first call.
Narrow streets - how do you build there?
Smaller equipment, alley/pull-out staging, hand-carry last leg, scheduled crane lifts. 6 Mt Washington projects since 2023.
Hillside drainage - why does it matter?
Hillside lots that drain wrong cause landslides. We engineer drainage, install subdrains, direct discharge to street or drywells - not to neighbors.
View-axis design for hardscape?
Schematic-design driver. Decks, terraces, overlook hardscape designed around the home's primary view direction.
What's a realistic full-exterior renovation?
$130K to $170K for facade + hillside hardscape + retaining + drainage + lighting + irrigation.
Mid-Century exterior details?
Honored. Exposed beam returns, geometric signage, integrated lighting, restored original hardware where present.
Soils engineering - is it required?
On any project touching retaining walls, foundations, or significant grading, yes. $3K-$8K typical investigation. Skipping is how hillside projects fail.
