San Carlos — Parking

Q: What parking ratio applies to a two‑bedroom apartment in a San Carlos MU district?

In San Carlos mixed‑use districts the ordinance requires 1.5 parking spaces per unit for two‑bedroom (and larger) units; at least one stall per unit must be covered where the table specifies covered spaces. See § 18.20.040 (Table 18.20.040‑A(1)).

Q: How close can required off‑site parking be to my building?

Nonresidential off‑site parking must be within 400 feet along a pedestrian route of the principal entrance it serves, and the city requires a recorded parking agreement reserving those stalls. See § 18.20.070 .

Q: How many bicycle racks do I need for a retail store?

Short‑term bicycle parking must equal 10% of the required automobile parking spaces , with a minimum of 4 short‑term spaces per establishment for commercial uses listed in § 18.20.080 ; racks must be within 50 feet of a main entrance and meet anchoring/size rules. See § 18.20.080 .

Q: If my commercial site doesn’t have room for the required parking, can I use valet or stacked parking?

Yes — stacked or valet parking is allowed if an attendant or automated system is present and the city receives adequate guarantees (e.g., a recorded guarantee that an attendant will always be present when required parking is used). See the general provisions that address stacked parking and attendant guarantees in § 18.20.030 .

Q: Who decides the parking rate when my use isn't listed?

If a use is not listed, the Director determines the parking requirement based on the most similar use and parking demand data. See § 18.20.040 (Other Districts / Director determination) .

Q: When must required parking be built?

On‑site parking required by the chapter must be installed prior to issuance of a certificate of occupancy for the uses they serve. See § 18.20.020(D) .

Overview

This page summarizes San Carlos's on-site parking, bicycle parking, and loading rules as written in the City Zoning Ordinance (Title 18). It explains how many spaces are required for common uses, where parking must be located, bicycle and loading rules, and district-level constraints and design requirements. All rules below are taken from the San Carlos Zoning Ordinance; consult the cited code sections and the City for parcel‑specific determinations. § 18.20.010–100 set the core rules for parking, loading, bicycle parking, and design standards.

Note: this page references related San Carlos pages where relevant: see the zoning overview and the development standards, design review, overlay districts, and ADUs pages for topics that interact with parking requirements. Also see the City’s adoption of the California Building Standards Code for building-level requirements.

District-by-district breakdown

Below are the San Carlos districts most directly implicated by parking rules. Each subsection shows the district name in bold, its on‑paper purpose, typical uses (as used by the parking tables), the key parking/placement rules that apply to that district, and where the district generally applies in the City.

MU (Mixed‑Use) districts — e.g., MU‑DC‑100, MU‑D‑100, MU‑D‑120, MU‑SC‑120, MU‑NB‑120, MU‑SB‑100/120, MU‑N‑40/50/120

Purpose / typical uses: Urban/commercial/residential combinations (retail, offices, restaurants, multi‑unit housing). See the Mixed‑Use chapter and building form standards.
Parking requirements: Mixed‑use parking rates and specific residential/unit rates are listed in Table 18.20.040‑A(1) (part of § 18.20.040). Examples: studio & 1‑bedroom = 1 space/unit (1 covered); 2+ bedroom = 1.5 spaces/unit; office = 1 per 450 sq ft; retail = 1 per 400 sq ft; restaurant = 1 per 250 sq ft.
Placement / design constraints: In many MU districts surface parking is required to be set back or placed behind buildings: the MU parking/placement figure and table indicate surface parking setback from street property line = 40 ft (or behind the building/interior side/rear) and above‑ground parking must have 8 ft building/plaza separation depending on the subdistrict standards; see the MU parking & loading standards table.
Where it applies: Mixed‑use zones along San Carlos commercial corridors and nodes; see the Zoning Map and MU chapter.

(For development form rules controlling parking location and frontage see the San Carlos Development Standards page.)

IA (Industrial Arts) District

Purpose / typical uses: Industrial, light manufacturing, and supporting office/customer areas.
Parking requirements: § 18.20.040 sets IA‑specific rate: 1 parking space per 2,000 sq ft of industrial area plus 1 space per 300 sq ft of office/customer area.
Placement: Truck docks, loading and service areas must be located and screened per general parking area design standards and per IA supplemental rules (build‑to and orientation rules may apply).
Where it applies: San Carlos’s industrial arts area(s) mapped in Title 18.

R / RS / Single‑Family Residential Districts

Purpose / typical uses: Single‑unit dwellings and accessory uses.
Parking requirements: Residential parking rates for multifamily vs. single‑unit are in § 18.20.040 and mixed‑use/residential tables; single‑unit minimums and garage/driveway rules appear in the general provisions. Example rule for garage conversion: conversion of a single‑unit garage to living space is allowed only for homes constructed before 1954 provided one off‑street parking space is maintained and garage dimension limits apply. (See § 18.20.030 (Residential Garage Conversion)).
Placement: Off‑street parking may be located in front yards only to the extent permitted by the residential development standards (garage‑in‑front rules, driveway/curb cut limits). See the Small Lot and RS standards for driveway/garage widths and setbacks.

(If you are planning an ADU, see the San Carlos ADUs guidance; state ADU law also affects how parking is applied. )

Public & Semi‑Public — e.g., P, PK, OS

Purpose / typical uses: Government facilities, parks, schools.
Parking & loading: Truck docks, loading, and service areas for these districts must be at the rear or interior sides of buildings and screened from streets and residential properties (see § 18.08.040(C)). Required parking numbers for these uses are governed by the Other Districts table when the use is not in a MU table.
Where it applies: Public parcels and park/open space lands.

Airport District

Purpose / typical uses: Airport operations and compatible uses; additional development rules (e.g., vehicular access and setbacks).
Parking: Airport district development standards permit limited parking in required front/exterior side yards as described in Table 18.09.040; detailed parking calculations fall under § 18.20.040 unless superseded by Airport chapter provisions.

Planned Development (PD) and Special/Subdivision Districts (Small Lot, etc.)

Purpose / typical uses: PD and small‑lot districts allow project‑specific adjustments to parking standards and may set bespoke ratios or shared parking approaches. PDs can modify parking, setbacks, and parking location through the approved PD plan; see § 18.10.
Small‑lot developments have specific garage width, driveway, and access rules (e.g., maximum garage width = 20 ft in some small‑lot single‑unit standards). Parking placement (alley/side street access encouraged) is enforced.

Key decision‑relevant standards (quick table)

Topic / Use	Decision‑relevant standard	Code Reference
Studio & 1‑BR units (MU)	1 space per unit; 1 covered required per unit	§ 18.20.040 (Table 18.20.040‑A(1))
2+ BR units (MU)	1.5 spaces per unit	§ 18.20.040 (Table 18.20.040‑A(1))
Office (nonresidential)	1 space per 450 sq ft (MU example) — other districts use Table 18.20.040‑A(3)	§ 18.20.040
Retail	1 space per 400 sq ft (MU example)	§ 18.20.040
Restaurant	1 space per 250 sq ft (MU example)	§ 18.20.040
IA district parking	1 per 2,000 sq ft industrial + 1 per 300 sq ft office/customer	§ 18.20.040 (IA rules)
Required loading (by gross floor area)	See Table 18.20.090‑A: e.g., 0 spaces for 0–6,999 sf; 1 for 7,000–30,000 sf; 2 for 30,001–90,000 sf	§ 18.20.090 and Table 18.20.090‑A
Short‑term bicycle parking	10% of required auto spaces (minimum 4 spaces per establishment) for specified uses; locate within 50 ft of main entrance	§ 18.20.080
Off‑site parking location	Nonresidential off‑site parking must be within 400 ft along a pedestrian route; recorded agreement required	§ 18.20.070
Construction timing	Required on‑site parking must be constructed prior to issuance of a certificate of occupancy for served uses	§ 18.20.020(D)

Practical guidance / interpretation notes

Start with § 18.20.040: determine whether your use is listed in the Mixed‑Use table, the IA rule, or the “Other Districts” table. If your use is not listed, the Director assigns the most comparable rate. § 18.20.040 explains that for unlisted uses the Director determines the requirement.
If your site is in a Mixed‑Use district, expect stricter placement rules (parking behind buildings and substantial street setbacks for surface parking); you may need structured or concealed parking to meet both lot‑line frontage and parking minimums. § 18.05 & § 18.20.040 are the cross‑references.
Bicycle parking is mandatory and sized: short‑term racks must allow the frame and one wheel to be secured to a stationary anchored object, each space min 2 ft x 6 ft, and must be ≤50 ft from the building entrance (exceptions for encroachment with sidewalk clearance rules apply). See § 18.20.080.
Loading requirements are explicitly tied to gross floor area via Table 18.20.090‑A; the Director can waive or increase spaces based on the use’s delivery profile. See § 18.20.090.
If you propose off‑site parking, you must supply a recorded parking agreement guaranteeing access and reservation of spaces; off‑site nonresidential parking must be within 400 feet along a pedestrian route. See § 18.20.070.

Checklist (for applicants)

Identify the applicable parking table: Mixed‑Use table (Table 18.20.040‑A(1)), IA rule, or Other Districts table and compute required automobile parking. § 18.20.040.
Provide required short‑ and/or long‑term bicycle parking per § 18.20.080 (counts, spacing, anchoring, and location).
Provide required loading berths per § 18.20.090 and Table 18.20.090‑A (or demonstrate to the Director why fewer are needed).
Confirm parking placement and setbacks consistent with district build‑to/parking‑placement rules (e.g., MU setbacks) in the applicable district chapter (e.g., MU rules in § 18.05).
If using off‑site parking, prepare a recorded parking agreement and ensure the lot is within 400 ft pedestrian route of main entrance. § 18.20.070.
If seeking a parking reduction or in‑lieu option, document eligibility and apply per § 18.20.050–060.
Include parking area design, surfacing, landscaping, screening and curb‑cut minimization measures per § 18.20.100 and related development standards.
Ensure required parking is constructed prior to certificate of occupancy (for new structures / uses) per § 18.20.020(D).

Risks & Ambiguities

Issue	Why it matters	What to verify
Unlisted use parking rate (Other Districts)	Director assigns comparable rate — could increase required stalls or require TDM.	Confirm the Director’s comparable‑use determination and appeal options; request written determination. § 18.20.040.
Eligibility for parking reductions/in‑lieu fee	Reductions affect project feasibility; criteria and credits may be discretionary.	Obtain the full § 18.20.050–060 text and meet required findings; ask planning staff how transit proximity is scored. Not fully shown in retrieved materials.
Off‑site parking location vs. pedestrian routing	400‑ft measurement is along a pedestrian route — a straight‑line measurement may not qualify.	Have staff confirm walk route measurement, curb cuts, and recorded agreement content. § 18.20.070.
Bicycle parking minimums and exceptions	Minimum 4 short‑term spaces per establishment for many uses may be binding for small shops.	Verify whether shared racks or plaza racks can serve multiple establishments; verify long‑term bicycle counts if you have employees. § 18.20.080.
Garage conversions and pre‑1954 rule	Conversion allowance tied to construction date and minimum retained parking; ambiguous for altered lots.	Confirm property’s construction date and whether the garage was “legally constructed”; consult Building/Planning. § 18.20.030(F).

Plain‑English summary

San Carlos requires on‑site automobile parking, bicycle parking, and loading based on your land use and zoning district. Mixed‑use districts have explicit per‑unit and per‑square‑foot rates (example: 1 space per studio/1BR; 1.5 per 2+ BR; office ~1/450 sf; retail ~1/400 sf) and place strong limits on street‑facing surface parking; bicycle and loading rules are mandatory and location‑sensitive. Always confirm the “Other Districts” table and any parking reduction/in‑lieu options with planning staff because the Director has discretion for unlisted uses and reductions. § 18.20.040–090 are the controlling rules.

Frequently asked questions

What parking ratio applies to a two‑bedroom apartment in a San Carlos MU district?

In San Carlos mixed‑use districts the ordinance requires 1.5 parking spaces per unit for two‑bedroom (and larger) units; at least one stall per unit must be covered where the table specifies covered spaces. See § 18.20.040 (Table 18.20.040‑A(1)).

How close can required off‑site parking be to my building?

Nonresidential off‑site parking must be within 400 feet along a pedestrian route of the principal entrance it serves, and the city requires a recorded parking agreement reserving those stalls. See § 18.20.070.

How many bicycle racks do I need for a retail store?

Short‑term bicycle parking must equal 10% of the required automobile parking spaces, with a minimum of 4 short‑term spaces per establishment for commercial uses listed in § 18.20.080; racks must be within 50 feet of a main entrance and meet anchoring/size rules. See § 18.20.080.

Does San Carlos require loading berths for commercial buildings?

Yes — loading is required by gross floor area per Table 18.20.090‑A (for example, 1 loading space for 7,000–30,000 sf, 2 for 30,001–90,000 sf); the Director can waive or require more based on the use’s needs. See § 18.20.090 and Table 18.20.090‑A.

Can I reduce required parking because my site is near transit?

The ordinance allows parking reductions in transit‑served locations and for shared parking arrangements; the specific reduction criteria and process are in § 18.20.050 (parking reductions) and the in‑lieu fee option is in § 18.20.060. The detailed eligibility criteria and required findings should be confirmed with planning staff. Not all reduction details were visible in the retrieved snippets; verify with the Code.

If my commercial site doesn’t have room for the required parking, can I use valet or stacked parking?

Yes — stacked or valet parking is allowed if an attendant or automated system is present and the city receives adequate guarantees (e.g., a recorded guarantee that an attendant will always be present when required parking is used). See the general provisions that address stacked parking and attendant guarantees in § 18.20.030.

Are there special placement rules for parking in Mixed‑Use districts?

Yes — many MU district standards require surface parking to be behind the building or set back from the street (the MU parking/placement standards indicate a 40 ft surface parking setback from the street property line in applicable MU tables). Confirm the specific MU subdistrict rules in the MU chapter and the parking tables. See § 18.05 and § 18.20.040.

Does converting a garage to living space remove my parking obligations?

Garage conversions are controlled: conversion of a single‑unit garage into living space is allowed only if the residence was constructed prior to 1954, one off‑street parking space will be provided, and the garage dimensions meet specified size limits. See § 18.20.030 (Residential Garage Conversion).

Who decides the parking rate when my use isn't listed?

If a use is not listed, the Director determines the parking requirement based on the most similar use and parking demand data. See § 18.20.040 (Other Districts / Director determination).

When must required parking be built?

On‑site parking required by the chapter must be installed prior to issuance of a certificate of occupancy for the uses they serve. See § 18.20.020(D).
