Menlo Park-area home addition and reroof under construction

Menlo Park's residential permit process is moderately predictable, but it has a few specific characteristics worth understanding before you submit. Here's how the process actually works in 2026.

The two-track system

Menlo Park splits residential applications into two general tracks:

Over-the-counter or expedited (no design review)

  • Kitchen, bathroom, and interior remodels with no exterior change
  • Re-roofs (same profile)
  • Window replacement (same size openings)
  • Solar installations
  • Standard ADUs that meet objective design standards (state law SB 9 / 10)

Plan check timeline: 2–5 weeks. Permit fees: $1,000–$4,000 typical.

Standard review

  • Additions over a certain square footage
  • Exterior changes
  • Hillside or sensitive sites
  • Tree-affecting projects
  • Properties in the Historic Resources Inventory

Plan check timeline: 6–12 weeks. Permit fees scale with project value.

Heritage tree ordinance

Menlo Park has one of the most aggressive heritage tree ordinances on the Peninsula. Protected trees include:

  • Oaks (any size)
  • Other native trees over certain trunk diameters
  • Any tree over 47.5" in trunk circumference

Removing or significantly altering a heritage tree without a permit is a misdemeanor with fines of $5,000+ per violation. Most projects affecting any tree need an arborist report and a Heritage Tree Removal Permit.

Hillside and seismic review

Properties west of Alameda de las Pulgas often fall in the Hillside zone, which adds:

  • Soils report (geotechnical)
  • Grading and drainage plans
  • Slope stability analysis for additions
  • Sometimes view corridor analysis

Add 4–8 weeks and $5,000–$15,000 in additional engineering for hillside lots.

Setbacks and FAR

Standard residential setbacks in Menlo Park: 20' front, 5' side (with adjustments), 20' rear. FAR varies by zone but typically caps total floor area at 35–45% of lot.

Verify FAR early in design — many additions have to be reduced after FAR calculations are run.

Typical project costs

Kitchen remodel (interior only)

  • Permit + plan check: $1,500–$3,000
  • Plan check timeline: 2–4 weeks

Single-story rear addition

  • Permit + plan check: $6,000–$12,000
  • Plan check timeline: 6–10 weeks
  • Total project timeline (contract to permit): 4–6 months

Detached ADU

  • Permit + plan check: $5,000–$9,000
  • Plan check timeline: 4–8 weeks (state ADU streamlining helps)
  • Total project timeline (contract to permit): 3–5 months

New construction

  • Design review required
  • Timeline: 8–14 months from concept to permit

Recent changes worth knowing

  • SB 9 (lot splits) and SB 10 are being implemented — Menlo Park has objective design standards published
  • Recent updates to the parking requirements (some projects no longer need replacement parking)
  • Streamlined ADU pre-approved plan sets available for some configurations
