Menlo Park — Overlay Districts
Overlay Districts under the Menlo Park local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
Menlo Park's zoning title establishes several overlays—local code tools that layer additional rules or permissions on top of the base zoning map to achieve targeted policy goals. The principal overlays in the Menlo Park Zoning Code are the Residential Overlay, the Affordable Housing Overlay (AHO), and the Emergency Shelter for the Homeless Overlay; each has its own purpose, permitted uses, and development rules tied to specific parcels or plan areas. Confirm parcel-level applicability with the city; the code lists APNs and tables for parcel-specific rules.
Notes on related topics: overlays interact with the base zoning and with the city's rules on development standards, parking, and design review. ADU rules remain governed by the ADU chapter and state law; see Menlo Park ADUs and the California Building Standards Code for building-code approvals.
Overlay-by-Overlay breakdown
Residential Overlay (Chapter 16.95)
- Purpose: The Residential Overlay is intended to "allow and encourage new or additional residential development on certain parcels" where the underlying zoning otherwise might not permit residential uses or where limited acreage is identified for residential development. § 16.95.010.
- Where it applies: The overlay is parcel-specific; applicable parcels and the allowed residential acreage for each parcel are listed in Table 16.95.015(A) (APNs and addresses). § 16.95.015. The table in the ordinance (image/table) identifies parcels such as portions of Sand Hill Road and Middlefield Road locations; verify the exact APN and acreage from the city's table. § 16.95.015.
- Typical permitted uses: Multiple dwellings and accessory buildings/structures associated with multifamily residential development are explicitly permitted. § 16.95.020.
- Key development rules: Residential development is limited to the acreage shown for each parcel (residential acreage may be located anywhere on the parcel), and projects must meet the development regulations and residential design standards in the chapter. § 16.95.030–.040. The overlay can be combined with the Affordable Housing Overlay. § 16.95.010.
Decision-relevant reference: see § 16.95.010, § 16.95.015, § 16.95.020, § 16.95.030.
Affordable Housing Overlay (AHO) (Chapter 16.98)
- Purpose: The Affordable Housing Overlay (AHO) is intended to incentivize affordable housing production (very low, low, extremely low and, for for-sale, moderate income) by providing density bonuses, incentives, and waivers on designated housing opportunity sites and specified plan areas. § 16.98.010.
- Where it applies: The AHO is applied to specific areas including the Menlo Park El Camino Real and Downtown Specific Plan area, properties zoned R-4-S(AHO), certain R-3 parcels near El Camino Real/Downtown, and housing opportunity sites listed in the adopted Housing Element Appendix (2023–2031). Use the ordinance maps/tables to confirm whether a parcel is within the AHO. § 16.98.030.
- Typical permitted uses / qualification rules:
- To qualify for AHO benefits, a project must be 100% residential or mixed-use, have 5 or more units, and provide a minimum share of affordable units (for rental projects at least 20% restricted to extremely low/very low/low; for for-sale projects at least 20% to extremely low/very low/low/moderate—see § 16.98.040 for exact breakdowns and thresholds). § 16.98.040.
- A portion of the affordable units must be very low or extremely low (e.g., at least 25% of the affordable units restricted to very low/extremely low, or 15% to extremely low); see the section for the precise options and calculations. § 16.98.040.
- Density bonuses and combinations with State law:
- The AHO grants a local density bonus (Table 1 in the chapter) and allows combination with State Density Bonus Law under particular thresholds. When combined, the AHO bonus is additive but subject to caps (in no case shall total density bonus exceed 65%, except for 100% affordable projects where higher caps apply; see § 16.98.050). § 16.98.050.
- The AHO density bonus can be used to increase residential density only; it cannot be used to increase nonresidential FAR/height except as allowed by other provisions. § 16.98.050.
- Other controls: Projects using the AHO must enter affordability agreements (recorded covenants), construct affordable units concurrently with market-rate units, and meet below-market-rate program guidelines. § 16.98.070–.080.
Decision-relevant reference: § 16.98.010–.080 (density bonus rules in § 16.98.050, affordability and agreements in § 16.98.040 and § 16.98.070).
Emergency Shelter for the Homeless Overlay (Chapter 16.99)
- Purpose: The overlay aims to enable emergency shelters while protecting nearby properties and neighborhood character. § 16.99.010.
- Where it applies: The overlay is strictly parcel-specific — it applies only to a list of APNs included in the chapter (the code lists the APNs). Any other uses on those parcels are regulated by the underlying zoning. § 16.99.020.
- Permitted and conditional uses:
- The only permitted use under the overlay is a facility housing the homeless with 16 or fewer beds (serving up to 16 persons) unless a use permit authorizes more. § 16.99.030.
- Facilities with more than 16 beds or actions that increase the cumulative total above 16 beds require a use permit. § 16.99.040.
- Development regulations and performance standards:
- Shelters must conform to the underlying zoning's development regulations except as specifically modified (notably, off-street parking rules can be adjusted under this chapter; the community development director may reduce parking need on demonstrated grounds). § 16.99.050. The chapter includes parking ratios expressed per employee, per family, and per bed and allows a small parking reduction for proximity to transit. § 16.99.050.
- Performance standards (e.g., waiting/intake area sizes, management plans, hours, on-site management) apply; modifications to performance standards require a use permit. § 16.99.060.
- Review procedures: A compliance review is required (application, noticing to property owners within 300 feet, a planning commission study session) and the community development director makes the final compliance determination not subject to appeal. § 16.99.070.
Decision-relevant reference: § 16.99.010–.070 (permitted uses in § 16.99.030, parking and development rules in § 16.99.050, performance standards in § 16.99.060, compliance procedures in § 16.99.070).
Quick reference table — key permitted uses and limits
| Overlay / Topic | Most decision-relevant standards or permitted uses | Code Reference |
|---|---|---|
| Residential Overlay | Multiple dwellings allowed; residential development limited to parcel-specific acreage in Table 16.95.015(A). | § 16.95.010–.030 |
| Affordable Housing Overlay (AHO) | Requires ≥5 units, 20% (min) affordable unit thresholds; local density bonus rules (Table 1), recorded affordability agreements (55-year or per chapter), combination rules with State Density Bonus Law. | § 16.98.040–.080 |
| Emergency Shelter Overlay | Only permitted shelter without use permit: facility with ≤16 beds; parking rules specific to shelters (spaces per employee, per family, per bed); 300‑ft notice and planning commission study session for compliance review. | § 16.99.030–.070 |
Checklist (what an applicant must satisfy)
- Confirm the parcel is within the intended overlay(s) (check Table 16.95.015(A) for the Residential Overlay; AHO and ESH overlay chapters list applicability). § 16.95.015, § 16.98.030, § 16.99.020.
- Meet the overlay-specific use and unit thresholds (e.g., ≥5 units for many AHO benefits; ≤16 beds for by-right emergency shelter). § 16.98.040, § 16.99.030.
- Prepare required supporting documents: site plans, affordability proposal, density-bonus calculations, and any required affordability covenant/agreements for AHO projects. § 16.98.040–.070.
- Demonstrate compliance with overlay development regulations and city development standards (setbacks, open space, FAR/density limits unless modified by the overlay). See applicable chapters and § 16.95.030, § 16.98.050, § 16.99.050.
- For emergency shelters: submit compliance review application, pay fee, follow 300‑ft noticing and participate in the planning commission study session; community development director issues final compliance determination. § 16.99.070.
- If requesting incentives/waivers under AHO or State Density Bonus Law, provide the financial/pro forma justification and comply with waiver rules; obtain any required approvals and record covenants prior to building permits. § 16.98.050–.080, § 16.97.040–.080.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Parcel applicability (APNs/tables are parcel-specific) | Overlay permissions are limited to listed parcels; building on a parcel not listed can be disallowed. | Verify the APN against Table 16.95.015(A) and overlay applicability language in § 16.95.015, § 16.98.030, § 16.99.020; contact planning staff. |
| Density bonus numeric table entries (Table 1) | The exact bonus percentages and caps drive feasibility and financing. | The ordinance references Table 1 in § 16.98.050; the image/table text was omitted in the source preview. Get the full table from the official code or planning staff. Not found in retrieved materials for full table values. |
| Interaction with State Density Bonus Law | Whether AHO bonuses add to State bonuses and caps affects allowable unit counts and waivers. | Confirm combination rules and caps in § 16.98.050 and review how incentives/waivers interplay with § 16.97 (State Density Bonus implementation). |
| Development-standard waivers and incentives | City allows waivers/incentives but the specific discretionary findings and exceptions vary by area (e.g., specific plan exemptions). | For El Camino Real/Downtown specific plan and other special areas, review § 16.97.085 and relevant specific-plan exemptions. Verify with planning staff. |
| Emergency shelter cumulative bed counts | The code limits cumulative beds through the chapter; exceeding thresholds requires a use permit. | Confirm cumulative bed counts allowed in § 16.99.030–.040 and check the APN list in § 16.99.020. |
Plain-English Summary
Menlo Park uses parcel-specific overlays to allow focused changes to what can be built: the Residential Overlay opens certain commercial or otherwise non-residential parcels to limited housing, the Affordable Housing Overlay gives density and other incentives to projects that meet specified affordability thresholds, and the Emergency Shelter Overlay permits small shelters on a short list of city parcels while imposing performance and parking rules. Always confirm whether your lot appears on the overlay maps/APN lists and follow the specific code sections for required agreements, notice, and review. Verify with the jurisdiction for parcel-specific interpretations.
Information Gaps
- The ordinance preview included images/tables that were omitted in the extraction: the exact entries of Table 1 in § 16.98.050 (AHO density-bonus percentages) were not fully viewable. Not found in retrieved materials — obtain full table from the official city code.
- Table 16.95.015(A) (Residential Overlay parcel APNs and allowed acreage) appeared as an image in the file; the full tabular text was truncated/omitted in the preview. Not found in retrieved materials — confirm APNs and acreage with the city's published table or planning department.

Frequently asked questions
Can I build housing on a parcel only if it’s in the Residential Overlay?
Yes — the Residential Overlay allows residential development only on the parcels specifically listed in Table 16.95.015(A) and only up to the acreage shown for each parcel; permitted uses include multiple dwellings and accessory buildings. Confirm your APN against the table before assuming eligibility. § 16.95.015–.020.
What affordable-unit minimums trigger AHO benefits in Menlo Park?
To qualify for AHO density bonuses an eligible project generally must provide at least 20% of its units as affordable (specific breakdowns vary by rental vs. for-sale and income tiers); see the exact thresholds and options in § 16.98.040. Also review § 16.98.050 for how the AHO density bonus is calculated. § 16.98.040–.050.
Can I combine the Affordable Housing Overlay bonus with the State Density Bonus?
Yes, under conditions. The AHO can be combined with State Density Bonus Law if project thresholds are met; combined bonuses are additive up to specified caps (see § 16.98.050 for the formula and caps, including the 65% cap in many cases and special rules for 100% affordable projects). § 16.98.050.
What’s allowed as a “by-right” emergency shelter in Menlo Park under the overlay?
On the APNs listed in § 16.99.020, a shelter housing the homeless with 16 or fewer beds is the only permitted-by-right use under the emergency shelter overlay without a use permit. Anything above that or actions increasing the cumulative total require a use permit. § 16.99.020–.040.
Do emergency shelters have different parking rules?
Yes. Shelters must meet the overlay’s parking standards (spaces per employee, per family, per bed) in § 16.99.050 but the community development director may reduce parking requirements if justified, and small reductions are allowed if the site is within a certain distance of transit. § 16.99.050. Link local parking guidance for design and calculations. Menlo Park Parking
Does the AHO require recorded affordability covenants?
Yes — before issuance of any building permit an affordability agreement/covenant ensuring continued affordability for the required term (the chapter specifies durability, e.g., 55 years in some provisions) must be recorded; see § 16.98.070. § 16.98.070.
If my parcel is in the AHO, am I required to use the overlay rules?
No. Properties within the AHO “may, but are not required to, utilize the rules and regulations of this chapter”; however, to receive AHO benefits you must follow the chapter’s requirements and record agreements. § 16.98.030–.040.
Where do I check setbacks, open-space and other objective rules when using an overlay?
Overlay approvals are layered on the base zoning and must comply with the city’s development standards unless a waiver/incentive is approved; check the applicable base-district development regulations and the overlay chapter’s development rules. § 16.95.030, § 16.98.050, § 16.99.050.
Who issues the compliance determination for an emergency shelter?
After the required notices and study session, the community development director or designee makes the final written determination of compliance for emergency shelter proposals; that determination is final and not subject to appeal per the chapter. § 16.99.070.
Are ADU rules affected by overlays?
Overlay provisions do not replace state ADU law or Menlo Park’s ADU chapter; ADUs remain governed by Chapter 16.79 and state ADU law. Overlays typically address multifamily or site-level incentives, not ADU ministerial entitlements. See the ADU chapter and state ADU law. § 16.79.030–.080. Menlo Park ADUs California ADU law
