Garage-to-JADU, garage-to-ADU, home office and in-law suite conversions in Foster City — permitted, Title 24 compliant, and built for the city's flat, reclaimed-land lots.
Foster City sits on filled and engineered land along the bay, and while that means almost none of the hillside grading questions that come up elsewhere in San Mateo County, it brings its own considerations — a higher water table and drainage patterns that were engineered for the neighborhood as a whole rather than left to natural grade. Garage conversions here are generally more straightforward from a structural standpoint since lots and garages tend to be fairly uniform across the city's planned-community layout, but drainage and moisture management still deserve a closer look than they would on higher ground. We confirm your specific lot's drainage situation before finalizing the design.

Foster City's reclaimed-land lots have a higher water table than higher-ground cities — we account for drainage and moisture management even though there's no hillside grading to worry about.
Existing garage slabs, framing and rooflines aren't automatically reused or automatically torn out — we assess what's structurally sound first.

It generally sidesteps the hillside grading questions that come up elsewhere in the county, but the higher water table near the bay means drainage and moisture management deserve real attention in the design. We evaluate this as part of every Foster City site walk.
A JADU stays within your garage's existing footprint, is capped at 500 square feet, and can share utilities with the main house — usually a simpler, faster permit. An ADU can be larger or detached, requires independent utilities, and has no owner-occupancy requirement.
Generally, yes — the city's planned-community layout means garages and lots tend to follow a fairly consistent pattern, which makes for a more predictable conversion process than in cities with more varied housing stock.
Yes — we prepare the Title 24 energy calculations and CF1R documentation as part of every permit package, and manage plan check correspondence directly with the city so you're not the one interpreting correction letters.
