Overview
Moraga’s land-use rules live in Title 8 (Planning and Zoning) of the Moraga Municipal Code; the town adopts a single official zoning map and then applies district-specific standards, planned‑development procedures, and a set of townwide chapters (design review, ridgeline/hillside protection, parking, etc.) to implement the General Plan. The local code organizes broad district families (single‑family/rural, multifamily, commercial/MCSP, planned development, open space, institutional) and a handful of specific‑plan and overlay rules that change standards inside Moraga Center, Rheem Park and special sites such as Saint Mary’s and Moraga Ranch. See the town’s official Zoning page for navigation and parcel lookup.
How Moraga's code is organized
- Title and table of contents: Planning and zoning rules are written as Title 8; the Town adopts a single Town Zoning Map (the “Town of Moraga Zoning Map dated February 13, 1991”) which is made part of Title 8 and controls district boundaries § 8.04.030.
- Chapters by topic or district: individual districts (for example the single‑family tables, MCSP districts, planned development, open‑space districts) are organized into stand‑alone chapters (examples: Chapter 8.24 for single‑family SFR districts, Chapter 8.32–8.42 for Moraga Center Specific Plan (MCSP) districts, Chapter 8.48 for Planned Development, Chapter 8.52 for Open Space). Each chapter includes permitted uses, development standards, and cross‑references to townwide standards.
- Administrative and procedural chapters: the code sets up the planning commission, design review board, zoning administrator and staff responsibilities (duties and appeal paths) in Chapter 8.08 and related procedural chapters; the design review procedures themselves are in the design‑review chapters (see design review).
Zoning district families
Moraga’s code is organized around explicit district chapters; key district families and representative chapters are:
- Single‑family residential (SFR 1 DU/acre, SFR 2 DU/acre, SFR 3 DU/acre) — dimensional tables, setbacks and lot sizes are in § 8.24.060 and related SFR provisions (maximum heights and setback rules appear directly in those SFR tables).
- MCSP (Moraga Center Specific Plan) districts — the MCSP contains multiple subdistricts and medium/high‑density multifamily and mixed commercial/retail/office designations (for example MCSP R‑6, R‑12, MCSP Mixed Retail/Residential, MCSP Mixed Office/Residential). Each MCSP district has its own development standards tables (see § 8.32.050, § 8.33.010, § 8.41.050, § 8.42.050).
- Planned Development (PD, PD‑C) — Chapter 8.48 establishes the Planned Development District (design and three‑stage approval: conceptual, general, precise) and allows flexible standards adopted as part of the PD review § 8.48.060–8.48.090; Chapter 8.50 (PD‑C) is a streamlining tool for commercial center redevelopment with specific PD‑C standards and applicability rules § 8.50.010 et seq..
- Open Space / MOSO — the open space rules (non‑MOSO and MOSO) and their density options and constraints are in Chapter 8.52, which also defines the Moraga Open Space Ordinance‑driven rules § 8.52.050–8.52.080.
- Institutional / Campus (Saint Mary’s College) — a dedicated chapter recognizes a campus master‑plan process and controls for Saint Mary’s, and the campus master plan is authoritative where it applies § 8.56.050–8.56.060.
- Overlay districts — overlays (for example the Moraga Ranch Overlay District) layer additional purpose, permitted uses and standards on top of base MCSP rules; see Chapter 8.65 for Moraga Ranch specifics and Figure 8.200‑2 for the mapped overlay.

Citywide development standards (high level)
The code combines district tables and recurring townwide chapters. Representative, enforceable examples from the code:
- Setbacks and lot sizes: single‑family tables set front yard setbacks of 25 ft (SFR 1) or 20–25 ft depending on density band and lot (see § 8.24.060 for the SFR tables and exceptions).
- Height limits: SFR districts generally cap height at 35 ft / two stories (with slope/step‑down exceptions), while MCSP districts list maximum primary building heights of 45 ft in many MCSP tables § 8.24.080 and § 8.42.050.
- Lot coverage / FAR: MCSP tables and multifamily chapters specify lot coverage caps (often 60% in MCSP) and explicit FAR caps (example: 0.85 non‑residential FAR; other MCSP tables permit up to 1.15 FAR when enclosed parking is provided) — see § 8.42.050 and § 8.34.060 for project‑scale FAR and coverage rules.
- Parking: required parking standards are maintained in a consolidated parking chapter — the chapters repeatedly cross‑reference Chapter 8.76 (Of‑Street Parking and Loading) for residential and nonresidential parking requirements; district tables refer applicants to § 8.76 for counts and loading standards. See references in § 8.41.050, § 8.42.050, § 8.34.060. [/us/california/moraga/parking]
- Design details and corridors: Moraga relies on the Moraga Center Design Requirements (cross‑referenced as § 8.200.050) and the Moraga Design Guidelines; specific corridor/ridgeline and scenic corridor controls are in Chapter 8.132 (scenic corridors) and Chapter 8.136 (hillside protections). These chapters add visibility, stepback, and design expectations above the numeric tables. [/us/california/moraga/design-review]
(For quick access to the town’s development‑standards overview, see the Development Standards page.) [/us/california/moraga/development-standards]
Specific plans & overlays
- Moraga Center Specific Plan (MCSP): MCSP districts are given their own chapters and multiple district subtypes (R‑6, R‑12, MCSP Mixed Retail/Residential, MCSP Mixed Office/Residential). MCSP chapters include first‑floor activity requirements on School Street, private open‑space minimums, and MCSP‑specific FAR/height/lot‑coverage tables; see § 8.32.050, § 8.33.010, § 8.41.050, and § 8.42.050.
- Rheem Park and other specific areas: Planned development designations for large parcels and Rheem Park references appear in the Planned Development chapter; PD approvals require conceptual/general/precise plan stages § 8.48.080–8.48.090 and the PD‑C chapter is tailored to existing commercial centers § 8.50.010.
- Moraga Ranch Overlay: the Moraga Ranch Overlay District modifies MCSP Commercial rules to preserve rural character and allow adaptive reuse (bed‑and‑breakfast, boutique hotel, additional retail) — see § 8.65.010–8.65.030 (overlay applicability and incorporated MCSP Commercial rules). [/us/california/moraga/overlay-districts]
Building permits & review — the procedural path
- Who decides: the planning commission, design review board, and zoning administrator have defined duties. The planning commission hears and decides land‑use permits referred by the zoning administrator and hears variances and rezonings; the design review board performs design review and the planning director is the zoning administrator (procedural roles in § 8.08.020–8.08.070). [/us/california/moraga/design-review]
- Typical permit workflow: small, ministerial work that meets objective standards may proceed through building‑permit and plan check (see grading and building cross‑references), while conditional uses, variances, PD or MCSP projects go through discretionary review (conceptual → general → precise PD stages § 8.48.080–8.48.090, PD‑C for commercial centers § 8.50.030–8.50.060). Building permits specifically in PD areas cannot be issued until the PD stages are complete § 8.48.150.
- Design review & appeals: design review is enforced via the design review board/administrator and appeals from design review or zoning administrator decisions go to the planning commission as the board of appeals § 8.08.030–8.08.060; the code also makes unauthorized permits void and provides enforcement remedies § 8.04.140–8.04.160.
- Submittal content: PD‑C and PD‑rezone applications require a PD plan with permitted uses, development standard changes, parking, landscaping, sign master plan, and proposed design standards (§ 8.50.050–8.50.060).
State housing law in Moraga
Moraga’s code repeatedly recognizes the primacy and effect of state housing law by qualifying many district development standards “to the extent consistent with state law” and by cross‑referencing density bonus provisions:
- General state‑law qualifier: multiple MCSP and project chapters state that development standards apply “to the extent consistent with state law” (examples § 8.42.050(A) and § 8.34.060(A)). That language means state ADU/JADU rules, SB 9, density‑bonus provisions, and other state mandates can override local numeric limits where state law requires it. [/us/california/housing-laws]
- Density bonus cross‑reference: the municipal code explicitly points to a local density‑bonus chapter by reference in the residential calculation rules (see reference to § 8.172 inside § 8.04.095); applicants should consult the density‑bonus provisions when a project invokes state density‑bonus law.
- ADUs / SB 9 / rent rules: a discrete local ADU chapter or explicit SB 9 implementation language was not found in the retrieved Title 8 excerpts provided for this review. Where the town does not adopt a conflicting ADU ordinance the state ADU laws apply; for concrete ADU procedures consult the town’s ADU page and state ADU law pages for ministerial timelines and standards. Not found in retrieved materials: specific Moraga ADU code §. Verify with the Planning Department. [/us/california/moraga/adu] [/us/california/california-adu-laws]
Practical orientation — what to check first on every project
- Confirm the parcel’s base zoning on the official zoning map § 8.04.030 (that determines the default district chapter and permitted uses). [/us/california/moraga/zoning]
- Read the applicable district chapter (SFR, MCSP subdistrict, PD, Open Space) for numerical tables on setbacks, heights, lot area and private‑open‑space minimums (see § 8.24.060, § 8.32.050, § 8.41.050, § 8.42.050). [/us/california/moraga/development-standards]
- Check overlays and special chapters for additional constraints: Chapter 8.132 (Scenic Corridors), Chapter 8.136 (Hillside Development), Chapter 8.65 (Moraga Ranch overlay), and campus overlay § 8.56 for Saint Mary’s. These can impose additional setbacks, stepbacks and design rules. [/us/california/moraga/overlay-districts]
- Confirm parking obligations by consulting Chapter 8.76 and any MCSP or PD‑C parking adjustments noted in the district chapter § 8.41.050 / § 8.42.050 / § 8.34.060. [/us/california/moraga/parking]
- For building‑code technical compliance and plan check, follow the California Building Standards Code (Title 24) and local building/grade cross‑references (the Municipal Code cross‑references Title 14 grading chapters where relevant). For building‑code rules see the state code resource. [/us/california/building-codes]
Information Gaps (what was not found in the uploaded excerpts)
- A discrete, local ADU/JADU chapter or explicit local SB 9 implementing ordinance was not present in the retrieved Title 8 excerpts — confirm current Moraga ADU rules with the Planning Department or the town’s ADU page. Not found in retrieved materials.
- I did not retrieve the full text of the town’s density bonus chapter § 8.172 (the code references it); applicants should consult that chapter and state density‑bonus law for calculations and affordable‑housing concessions. Reference to § 8.172 appears in § 8.04.095; the density‑bonus chapter itself was not included in the excerpts I reviewed.

Who this affects
Frequently asked questions
What zoning districts does Moraga have?
Moraga organizes its base districts in Title 8: single‑family SFR bands (1, 2, 3 DU/acre) with numeric tables in § 8.24.060, several MCSP subdistricts (R‑6, R‑12, MCSP Mixed Retail/Residential, MCSP Mixed Office/Residential) in § 8.32–8.42, Planned Development in Chapter 8.48, Open Space/MOSO in Chapter 8.52, and institutional/campus designations (Saint Mary’s) in Chapter 8.56. Check the official zoning map § 8.04.030 to see which chapter applies to a parcel.
Do I need a permit to remodel my house in Moraga?
Likely yes for work that affects the building envelope, structural systems, grading, or utility connections — small interior work that doesn’t change use or structural elements may be ministerial. The SFR chapters set height and setback limits such as § 8.24.060/8.24.080; unauthorized permits are void and enforcement is allowed under § 8.04.140–8.04.160, so confirm with planning and building staff before starting.
Does Moraga have a Moraga Center Specific Plan (MCSP) and what’s special about it?
Yes — the MCSP is implemented through several chapters with MCSP subdistricts and detailed tables for setbacks, heights, FAR, first‑floor activation on School Street, and private open space (see § 8.32.050, § 8.41.050, § 8.42.050). MCSP standards frequently cross‑reference the Moraga Center Design Requirements at § 8.200.050 for design guidance.
Where are parking requirements set in Moraga?
District chapters defer to the consolidated parking and loading chapter: applicants should consult Chapter 8.76 (Of‑Street Parking and Loading); MCSP and multifamily chapters repeatedly point to Chapter 8.76 for required residential and nonresidential parking calculations (see references in § 8.41.050, § 8.42.050, § 8.34.060). [/us/california/moraga/parking]
How does design review work in Moraga?
Design review is a formal part of Title 8: the design review board’s duties are set out in the procedural chapters and the design review board performs the functions prescribed in the design‑review chapters (§ 8.08.030 and cross‑references to Chapter 8.72). Smaller design determinations may be made by the design review administrator (planning director) while appeals go to the planning commission.
If my lot is visible from a scenic corridor, are there extra rules?
Yes — development fronting or visible from a major scenic corridor is subject to additional setback, stepback and design guidelines in Chapter 8.132 and the MCSP chapters’ cross‑references to § 8.200.050; the scenic‑corridor chapter explicitly allows more restrictive setbacks and design controls for corridors § 8.132.050.
Can I use density bonus or other state law tools to exceed local limits?
Moraga’s code acknowledges density bonus and state preemption where applicable (residential calculation rules reference a local density bonus chapter § 8.172 inside § 8.04.095 and many district tables qualify standards “to the extent consistent with state law”). Check the density‑bonus chapter and consult planning staff, because the density‑bonus provisions and state law may change allowable unit counts and concessions.
Does Moraga have rent control?
No local rent‑control chapter appears in the Title 8 excerpts reviewed; housing‑rent regulation is typically a municipal code topic in another title if adopted. Not found in retrieved materials — verify with the Town Attorney or Housing staff.
Is there a special process for large institutional projects (Saint Mary’s)?
Yes — Saint Mary’s College uses a campus master plan process; the town may require a master plan for large institutional uses and the campus master plan prevails over conflicting Title 8 provisions for parcels covered by the campus plan § 8.56.050–8.56.060.
